Card with inhibit given remote interrogation
Contact-free cards that have at least two coupling elements spatially separated from one another such as, inductor coils, capacitors plates or photoreceivers, that utilize the effects derived from the spatial distance of the coupling elements from one another, i.e. stereo effect, is provided. The contact-free chip cards use the stereo effect to decide whether they are located within a prescribed range of a transmitter receiver. The range of the access can be reduced further, but cannot be increased beyond a fixed limit. Thus, access to the data of such cards outside this range is precluded. Such cards can additionally be equipped with means for switchable authorization of remote access. The contact-free card apparatus of the present invention further provides that it is the card itself and not the card environment that decides whether it is located in the near range of the terminal device such that it allows protectable access to its data and prohibits access from a greater distance.

1. Field of the Invention
The present invention is directed generally to chip cards and more specifically to a chip card with the capability of inhibiting remote interrogation of the card.
2. Description of the Related Art
Plastic cards that contain a semiconductor chip (i.e., chip cards, smart cards, intelligent chip cards etc.) are being increasingly utilized in the marketplace. The chips function as data storage devices, microprocessors, input/output modules and much more. They serve purposes such as telephoning, parking, paying for goods and services, conveying credits, controlling access, acquiring time, etc. In their many-faceted embodiments and, in particular, as multi-application cards (cards which are capable of handling a plurality of functions on a single card), these cards allow the storing of personal data. The data on a card provides information about the owner of the card and the card owner's behavior.
Chip cards are mainly known in two technical embodiments, contact cards (voltaic cards) and contact-free (non-voltaic) cards. Contact cards require voltaic contacts at their surface for faultless functioning. Contact-free cards forego these contacts and contain transmission coils, capacitor plates or optical elements for transmitting energy and/or data. The energy required for the operation of the card can be acquired from a battery, particularly a battery located in the card.
There are two embodiments of contact-free chip cards; international standardization is underway for both of these embodiments. Close-coupled cards, for example C2.RTM. CARDs, should only be usable over short distances according to ISO 10536. Other cards (remote-coupled cards) work in a different way and can be used over greater distances. The standardization of these remote-coupled cards is still in its infancy. The discrimination between contact-free cards is gaining increasing significance because of the problem of unnoticed access to the card. Table 1 provides a rough overview of the conditions with respect to the usability of the various cards at different distances.
TABLE 1 ______________________________________ Type Contacted Contact-Free ______________________________________ Standard ISO 7816 ISO 10536 No Standard Usability (remote-coupled) close + + + far - - + ______________________________________
It is virtually impossible when the voltaicly contacted card is used for a means to gain access to the content of the card, without being noticed, as long as the owner has control of the card. However, the conditions are entirely different with contact-free cards. The content of such cards can be accessed without an electrical connection between the card and the terminal device, i.e., wirelessly (contact-free) by definition. Such contact-free cards operate, for example by way of electrical coupling, magnetic coupling, electromagnetic radiation, lightwaves, microwaves, acoustic transmission or combinations of these principles. Thus, the access of the terminal device to the content of the card can be beyond the control of the card owner in these cases. Fundamentally, the terminal device can access the content of the card unnoticed.
Since the data in the remote-coupled card can be accessed both in a terminal device (terminal), as well as from a greater distance outside the terminal, a discrimination between close-coupled chip cards on the one hand and remote-coupled chip cards on the other hand functions properly only when the close-coupled cards necessarily preclude access from a distance.
Contact-free cards contain a chip embedded in the carrier material in a way that cannot be manipulated. Also, contact-free cards have a longer service life than voltaicly contacted cards. Specific embodiments of contact-free cards offer the ergonomic advantage that they can be operated at the terminal without taking into consideration the geometrical orientation of the four different operating positions along the card's longitudinal axis. Most likely the use of the contact-free chip cards will become widespread in addition to that of the voltaic chip card, and advantages will accrue therefrom for the user of the contact-free card.
Card issuers counter the disadvantage of unnoticed access to data of contact-free cards with the argument that their cards allow "remote transmission" only from a limited, small distance. The range is allegedly limited in the manner desired. The counter-argument thereto is that the range can be arbitrarily expanded, within the technologically-possible limits, after an adequate boost of the intensity of the information carrier output by the transmitter. The limits between near operation and remote operation are therefore blurred. The unauthorized manipulation of the card by manipulation at the transmitter cannot be precluded in a documentable fashion. The range of the data traffic is only limited by the intensity of the transmitting medium and can be made arbitrarily great within the scope of feasible technology.
Another argument is that encoding of the data traffic between the card and a specific terminal can protect against unnoticeable access to the data in the card. The counter-argument thereto is that not only does a stolen or simulated terminal likewise meet the function thereof, but that the afore-mentioned boost in intensity can again be used. The encoded data traffic can also occur remotely and the encoding thus has no value as a protective mechanism.
Particular purveyors of products or services--especially banks that accommodate credits or lines of credit on cards of the type under consideration here, have special problems. For instance, such banks can only assume responsibility for the proper condition of the card information content when the card necessarily must be physically inserted into a terminal for processing. The terminal must also be capable of retaining the card when necessary as soon as an error in the processing is found. It is unlikely that such banks will allow a manner of commercial use that cannot irrevocably and non-manipulably provide such a minimum security level.
Thus, a solution is needed for cards which carry out specific functions only within a range predetermined by the card. Then, this solution can also be applied to other problems of non-contacting data transmission, such as, the parameterizing and interrogation, as well as transmission of data to/from contact-free heart pacemakers.
Two possibilities are known for protecting the owner of a contact-free card against unnoticed access to his card data:
the owner of the card is forced to plug his contact-free card into a terminal because the card does not function outside the terminal; and
the card user can intentionally and consciously withhold the card from contact-free data transmission by actuating appropriate technical means, i.e. by providing an enveloping shield or operating a switch.
As a result of the latter possibility, the owner of the card not only suppresses the potentially undesired remote access, but also the near access desired in a proper use of the card. No unassailable criterion for distinguishing between near and remote operation exists. For making a card inhibited in this way accessible again for desired, authorized near operation, particularly for intentional incrementing or decrementing of credits in a terminal device, of course, the user must either remove the shield or return the switch to the position to provide a response capability.
This cancellation of the inhibit need not be exclusively manually and intentionally required on the part of the owner; it is also conceivable that the terminal automatically cancels the inhibit with technological means. Whether the inhibit is manually or automatically canceled, protection against remote access, particularly such a remote access by attacking with high intensity is then lost.
In the automatic case, the prior art requires shielding the terminal around the card. This, in fact, leads to a defined distinction between near/remote: near is within the shield and remote is outside the shield. Also, no outside operation can overcome this hurdle no matter how great its intensity. However, the undesirable, physical outlay of shielding the terminal yields a great disadvantage of this solution. Specifically, the quality of the protection is not defined by the card but by its environment. Thus, the card sacrifices control over its data to the environment in which the card is used.
In the manual case, the unprotected time span is substantially lengthened when the owner has the card in his hand outside the terminal device between deactivation and activation of the protection, which is an especially dangerous situation. A mobile shielding around the card that, upon introduction of the card into the terminal device, is subsumed in the afore-mentioned shielding of the latter is equally unreasonable. It should be fundamentally noted that shielding is nothing more than means for attenuating the transmission intensity. More intelligent features are not inherent therein.SUMMARY OF THE INVENTION
It is an object of the present invention to provide protection against unnoticed access of the data on cards working contact-free wherein the card itself--and not its environment determines, in a way that can be unmistakably reduplicated, whether it is located in the near range (of a terminal device) and only allows protectable access to its data so that the card controls the access.
Another object is to provide a card wherein the contact-free card also only allows certain functions as necessary when it is plugged into a terminal in the same way as a contacted card. To this end, the contract-free card must automatically and necessarily activate or deactivate functions dependent on unambiguously definable physical features that cannot be varied unsupervised (particularly paths, lengths, distances). It should not be possible with such a contact-free card to overcome the access inhibit from an inadmissibly great distance, particularly by increasing the transmission power of the write/read terminal.
Contact-free cards that have at least two coupling elements spatially separated from one another such as, in particular, inductor coils, capacitor plates or photo receivers available to them can meet this demand by using effects that derive from the spatial distance of the coupling elements from one another (particularly known as stereo effect). Contact-free chip cards that use the stereo effect automatically and necessarily decide whether they are located within an invariable, prescribed range of a transmitter/receiver. Given these cards, the range of the access can in fact still be reduced as a result of inadequate intensity but can clearly not be raised beyond fixed limits due to an arbitrarily high intensity of the coupling medium. Access to the data of such cards outside this range can thus be precluded when the exclusion is intended in conformity with the use. When such cards are additionally equipped with a means for switchable authorization of remote access, then these cards can utilize the advantages of contact-free card technology and also avoid their disadvantages.
An embodiment of the present invention provides an apparatus wherein the electronics of a contact-free card automatically recognize whether the card is in a spatial zone whose dimensions are clearly limited by the geometry of the card and not by the intensity of the coupling field.
According to the present invention, a "close-coupled card function" is a card function that can only be utilized in such a limited spatial zone that surrounds the card, the expanse thereof being limited by the dimensions of the card and/or by the expanse or geometrical arrangement of its function-defining component parts and not being capable of being expanded by increasing the field strength to an enlarged spatial zone.
The present invention also provides for a distinction between "close coupling cards" and "remote coupling cards" for use in the international standards,BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 illustrates "stereo effect" zones for a contact-free chip card and a terminal of the present invention. There are two spaces wherein a contact-free card having two coupling elements KS.sub.-- L and KS.sub.-- R (denoting, in particular, "left card coil" and "right card coil") according to ISO 10536 can automatically evaluate its distance (quasi by stereo effect) from the corresponding coupling elements of the terminal transmitters TS.sub.-- L and TS.sub.-- R (denoting, in particular, "left terminal coil" and "right terminal coil") with especially sharp separation. Due to their special significance, sections through these two spaces are shaded in the figure. These are the stereo-technical zones of the antiphase crosstalk of transmitters having a pronounced directional characteristic onto receivers having a pronounced directional characteristic (dipoles couple onto dipoles). The manner in which these special spaces arise shall be treated in detail later with reference to FIG. 2. Since the distance of the reception elements KS.sub.-- L and KS.sub.-- R from one another--referred to here as a stereo base--is invariable in the card, the stereo base defines the greatest range in which the card can document and use the stereo effect.
In an upper card position POSITION 1, both receiver elements KS.sub.-- L and KS.sub.-- R are respectively located in a shaded zone. Thus, the stereo effect can take effect. The antiphase crosstalk promotes the channel separation because the corresponding element couples over the short distance without phase angle rotation (TS.sub.-- L couples directly onto KS.sub.-- L and TS.sub.-- R couples directly onto KS.sub.-- R), whereas the non-corresponding element simultaneously couples crossed with the wrong phase (TS.sub.-- L couples with the wrong operational sign onto KS.sub.-- R and TS.sub.-- R likewise couples with the wrong operational sign onto KS.sub.-- L). The noise channel (respectively TS.sub.-- L with reference to KS.sub.-- R and, correspondingly, TS.sub.-- R with reference to KS.sub.-- L) acts subtractively on the useful channel (respectively TS.sub.-- L with reference to KS.sub.-- L and, correspondingly, TS.sub.-- R with respect to KS.sub.-- R). As a result of the quadrature phase deriving from ISO 10536, each of the two reception elements KS.sub.-- L and KS.sub.-- R in this position is best suited for receiving the signal respectively intended for it by TS.sub.-- L and TS.sub.-- R with such sharp separation that the following evaluation can generate the desired location information therefrom.
In a lower position POSITION 2, the card is at a greater distance from the transmitter elements TS.sub.-- L and TS.sub.-- R. The two reception elements KS.sub.-- L and KS.sub.-- R no longer lie in a respectively shaded zone at the same time. Therefore, the stereo effect is greatly decreased. In this case POSITION 2, the figure already shows the centers of the two reception elements KS.sub.-- L and KS.sub.-- R in the stereo-technical zone of equiphase crosstalk. The transmission elements TS.sub.-- L and TS.sub.-- R now act only additively on the reception elements KS.sub.-- L and KS.sub.-- R in terms of a center of gravity--the channel separation disappears, and the stereo transmission has become a monophonic transmission. As a consequence of the afore-mentioned quadrature phase, both reception elements KS.sub.-- L and KS.sub.-- R here already carry--by contrast to POSITION 1--nearly exactly the same signal from which, due to the lacking distinguish ability, less location information can be acquired the farther POSITION 2 is located from POSITION 1.
FIG. 2 illustrates the derivation of the shaded zones shown in FIG. 1. The terminal coils TS.sub.-- L and TS.sub.-- R are again the transmission elements. Particularly fashioned as dipoles, the terminal coils are not infinitely short like a Hertz dipole and therefore do not supply spherical, but approximately rotation-elliptical flux surfaces, whose sections are qualitatively identified in FIG. 2. In the figure, the two field vectors of the two transmission elements TS.sub.-- L and TS.sub.-- R reside parallel perpendicularly parallel relative to one another; they are visibly directed upward, so that the flux in FIG. 2 visibly emerges upwardly from the dipole TS.sub.-- L and TS.sub.-- R and in turn penetrates into the respective dipole at the bottom. The flux of TS.sub.-- L is indicated with medium bold face lines and that of TS.sub.-- R is indicated with thin lines. For the purpose of further observations, let this arrangement, in particular, be geometrically stationary; only the generated flux is, in particular, an alternating flux.
The card coils KS.sub.-- L and KS.sub.-- R, in particular, are likewise magnetic dipoles, but now act not as sources like the terminal coils TS.sub.-- L and TS.sub.-- R, but act as sinks. Their two field vectors likewise reside parallel relative to one another and, moreover, likewise particularly reside perpendicularly in the figure and, thus, parallel to the above-described field vectors of the transmission elements TS.sub.-- L and TS.sub.-- R. All the coils, TS and KS, are symbolicly shown in the figure as side views of pancake coils. By contrast to the transmission elements TS.sub.-- L and TS.sub.-- R, the reception elements KS L and KS.sub.-- R are not presumed to be stationary. Rather, they can be shifted parallel without rotation of their field vectors in order to be able to study the different system conditions that are of interest. Correspondingly, further illustrated attitudes of card coils are specifically referenced as KS.sub.-- L' and KS.sub.-- R', KS.sub.-- L" and KS.sub.-- R" as well as, finally, KS.sub.-- L'" and KS.sub.-- R'".
An especially interesting aspect of the flux lines are those singularities that supply no contribution to the induction in one or both card coils. Since the field vectors of the card coils KS.sub.-- L and KS.sub.-- R were previously assumed to be perpendicular, these singularities regularly occur in the field where the flux lines proceed horizontally. The lower half of these singularities are shown, and the loci of the horizontal tangents at all flux lines of the plane of the drawing are entered with heavy lines. These are the two lines KS.sub.-- LL and KS.sub.-- LR that are caused by the transmission element TS.sub.-- L and the two lines KS.sub.-- RL and KS.sub.-- RR that correspondingly derive from the transmission element TS.sub.-- R. These two line pairs are shown in FIG. 1 as the shaded area limits.
These loci are indispensably used for the demarcation of the local regions having different effects of the transmitted field on the signals induced in the receivers. The upper half of the figure is assumed to be known for symmetry reasons in the following conclusions. It can be easily seen that every imaginable flux line in the figure both to the left of the line KS.sub.-- LL as well as to the right of the line KS RR proceeds from top to bottom through an arbitrary card coil KS (the case KS.sub.-- L"/KS R" in FIG. 2). It is defined that the card coils KS are electrically polarized such that the induced voltage is negative in this specific instance. The analysis of the situation close to the center of the figure demands somewhat greater attention because the oppositely directed fluxes can superimpose there. The affected medium is defined as linear, and the result is defined by linear superposition. When an arbitrary card coil KS is located under the lines KS.sub.-- LL and KS.sub.-- LR, then the voltage induced therein because of TS.sub.-- L is positive as a consequence of the above-defined electrical polarization. When, correspondingly, an arbitrary card coil KS is situated under the lines KS.sub.-- RL and KS.sub.-- RR, then the voltage induced in it because of TS.sub.-- R is likewise positive. Correspondingly opposed, the voltage caused by TS.sub.-- L is negative in a KS above the lines KS.sub.-- LL and KS.sub.-- LR and, correspondingly, the voltage caused by TS.sub.-- R in a KS above the lines KS.sub.-- RL and KS.sub.-- RR is likewise negative.
Let the result of the superposition of the individual couplings from the two sources TS to one sink KS be referred to as equiphase or antiphase crosstalk--dependent on the individual flux direction and, consequently, on the induced polarity. When the two fluxes of TS.sub.-- L and TS.sub.-- R result in the same polarity of the induced voltage in the respective KS, let this crosstalk be called equiphase. Consequently, the crosstalk must be called antiphase when said two fluxes each induces an opposite polarity. According to this definition, FIG. 2 is to be interpreted in the following way: the shaded zones in FIG. 1 experience antiphase cross talk; all other zones in both figures, however, experience equiphase crosstalk. As mentioned, the upper half in FIG. 2 shall not be separately discussed since it is symmetrical to the lower half.
No crosstalk occurs on the bold face lines in FIG. 2. One of the two emissions of TS.sub.-- L or TS.sub.-- R is always clenched thereat. Thus, perfect channel separation prevails. Assuming for the following observations that the stereo base is uniform, let the distance of the two KS from one another be consistent and of the same size as the distance of the two TS from one another. When this arrangement is then displaced along the bold face lines, where these lines respectively proceed parallel to one another, then the afore-mentioned, perfect channel separation takes effect all the way into the induced voltages. Only a single signal from one of the two transmitters TS.sub.-- L or TS.sub.-- R appears at the output of each of the two card coils without crosstalk. The farther the reception coil pair KS is shifted away from the transmission coil pair TS along these bold face lines proceeding parallel to one another, the smaller the solid angle that these lines proceeding parallel to one another assumes becomes. The solid angle in which the usable channel separation prevails also becomes smaller in order to derive an authorization for the access to the card contents therefrom.
Thus, it is not possible to gain unauthorized access by exerting adequate intensity from a distance to utilize the channel separation in this solid angle. The attacker must simulate the transmission coil pair TS with the correct stereo base and align one of the two sectors that are shaded in FIG. 1 such that the card is impinged with the adequate channel separation.
In addition, a further impediment for the unauthorized attack is that the attacking transmitter does not know the alignment of the card in space. The deal arrangement of parallel field vectors shown in FIG. 2 for use in file operation will not be accidentally present in noise operation, so that only the projections of the relevant geometrical paths act on the card coil pair KS. The geometry of the noise transmitter and of the attacked card then already fails to coincide with reference to the stereo base. Over and above this, the operation also becomes noise-resistant on these singular parallels when the two signals transmitted by TS.sub.-- L and TS.sub.-- R have, in particular, the same frequency, are synchronized phase-locked with one another, carry quadrature phase and, finally, when the binary modulation is a symmetrical quadrature modulation (QM). When, in particular, the sum signal as well as the difference signal of the induced voltages from KS.sub.-- L and KS.sub.-- R is then formed in the card, it can be shown that the good channel separation on the singular parallels is not adequate insofar as the card produces the clock of a synchronous detector from the difference signal and allocates the sum signal to the binary modulation. The following occurs as a result. In FIG. 2, the card supplies an unvaried, phase-stable clock from the difference signal and stable quadrature modulation from the sum signal perpendicularly under the transmitters TS.sub.-- L and TS.sub.-- R in all positions on and between TS.sub.-- L and TS.sub.-- R above KS.sub.-- L and KS.sub.-- R at half the height to KS.sub.-- L' and KS.sub.-- R' below.
By contrast thereto, sum signals and difference signals are interchanged with one another in the distance on the afore-mentioned, critical parallels. The recovered clock is dependent on the binary modulation and merely has to be electrically discarded because of the accompanying phase shifts. Above the stereo card separation point (this is the interconnection in FIG. 2 of the two lines KS.sub.-- LR and KS.sub.-- RL in space, two identical cones intersect in a hyperbola whose apex is this intersection), the clock from the difference signal is stable as in the afore-mentioned useful operation but the binary modulation is complementary to the useful modulation, this representing an unmistakable request to the card to segregate a noise signal. The inversion of the conditions occurs at the level of the stereo card separation point that was just defined: both sum signal as well as the difference signal carry quadrature modulation thereat and can likewise be rejected by the card because of this recognizable defect.
Added thereto is that the signal PHS of FIG. 4 cannot rise above 50% high along the singular parallels being discussed here. It is thus meaningful to select the phase limit value, according to FIG. 4, higher than 50% high in order to combat the simulation of useful operation on the singular parallels.
As set forth above, the conditions given the operating mode particularly elected on a straight line between and in the positions of TS.sub.-- L/TS.sub.-- R through KS.sub.-- L'/KS.sub.-- R' are unambiguous, significant and stable. This is in contrast to the other positions, in which they are not so at the same time. This lacking proof is unproblematical as a negative proof for the zones under all bold face lines in FIG. 2. There is no difference signal thereat the farther, all the less significant--because both receivers KS.sub.-- L and KS.sub.-- R are impinged by the same flux, i.e. no clock. The same is true far enough to the right and left of all parallel lines.
The environment of the singular point is the actual useful zone because--referring to FIG. 8--only there does the antiphase crosstalk lead to phase spread which leads to a phase signal PHS>50% high in FIG. 4. As a result of defining the phase limit value above 50% high, the useful zone, on the one hand, can be made smaller in the direction toward greater reliability and, on the other hand, the signal-to-noise ratio can be improved to prevent undesired attacks from noise regions.
It has already been particularly assumed in the legends to FIG. 2 that the two transmitters TS.sub.-- L and TS.sub.-- R transmit with quadrature phase. This idea is initially defined quite specifically only in the time domain in roughly qualitative fashion by FIG. 3. Further supplementary details derive from the vector presentation that follows later. With reference to the periods dimensioned below, TS.sub.-- L is 45.degree. early and TS.sub.-- R is 45.degree. late. As known from FIG. 2 in the space domain, no contribution comes from TS.sub.-- R in position KS.sub.-- L', i.e. the phase of KS.sub.-- L' is identical to that of TS.sub.-- L. Given a qualitative consideration of the superposition while respecting the spacing conditions, KS.sub.-- L comes earlier than KS.sub.-- L' because the negative flux of TS.sub.-- R (definitely 90.degree. earlier than TS.sub.-- L) is added thereat (antiphase crosstalk). Correspondingly, KS.sub.-- R comes later than KS.sub.-- R' because negative flux of TS.sub.-- L (all together 90.degree. later than TS.sub.-- R) crosstalks thereat. These two latter chronological curves, however, are not shown in FIG. 3.
It may be seen from FIG. 2 that the time curve nearly coincides with KS.sub.-- L' in the position KS.sub.-- R'". Due to the antiphase cross talk from TS.sub.-- R, KS.sub.-- R'" comes somewhat earlier than KS.sub.-- L', but this is lost in FIG. 3 due to the resolution of the drawing. In position KS.sub.-- L'", both transmitters TS.sub.-- L and TS.sub.-- R couple antiphase; for drafting reasons, however, FIG. 3 leaves the influence of the remote transmitter TS.sub.-- R out of consideration. In fact, KS.sub.-- L'" comes somewhat later than shown; in principle, however, one can see in FIG. 3 with reference to the opposite operational signs of the two chronological curves of KS.sub.-- R'" and KS.sub.-- L'" that the sum signal disappears and that no good modulation can be acquired according to the manner selected in the legends of FIG. 2.
In a comparable way, the chronological curves of KS.sub.-- L" and KS.sub.-- R" in FIG. 3 can be derived from FIG. 2. The two transmitters similarly couple KS.sub.-- L" antiphase onto the two receivers; in terms of the drawing, however, the reversed phase of TS.sub.-- R dominates here. Together, the two coils do not supply a difference signal, i.e. no clock.
The extensive comments about FIGS. 1, 2 and 3 provide answers from various points of view as to how an embodiment of a card with fixed stereo base according to ISO 10536 and the use of quadrature phase and quadrature modulation can defend against potential attacks on the control of the card owner regarding the data on the card. If an attacker were to manipulate the stereo base of the transmitter by arranging the coils differently in the terminal, then FIG. 2 need not be entirely redrawn. After clarifying the projection of the stereo base that is then effective onto the drawing, only the stereo base of the card KS need be formally reciprocally adapted. The sensitivity of the card to the space domain is then in fact no longer maximal but is still noticeable. When the card is turned within the plane of the drawing of FIG. 2, then the shaded structure in FIG. 1 rotates oppositely. This improves the selection in the preferred space domain. In case of doubt, the card functions with the greatest separation in the environment of the singular point referred to as stereo card separation point (SCSP). All flux components that are vertical in FIG. 2 disappear in the SCSP; when one moves around the SCSP with a reception coil, the alternating flux pointer turns to the same extent (identically directed or oppositely directed dependent on the operational sign of the quadrature phase). In the vector field, this singularity is called rotor (eddy).
When any of the necessary boundary conditions are lacking, then the card either recognizes no clock or no modulation and does not allow any protectable functions in this operating condition but only allows unprotected operating functions--insofar as the intensity-conditioned range (the strength of the magnetic field particularly set forth here decreases with the third power of the distance) and the demodulation process that is less intelligent for unprotected functions allows this.
A chip card system that contains the transmission means symbolically indicated in FIGS. 1, 2 and 3 at TS.sub.-- L, TS.sub.-- R, KS.sub.-- L, KS.sub.-- R, etc., is the subject matter of U.S. Pat. No. 4,697,183 (incorporated herein by reference). This patent does not recite how it is assured that the card execute only specific functions when it is located in a spatial zone in which the stereo card separation point SCSP lies, a decision regarding near operation (close coupling) being thus established. It is only when the internal electronics of the card carries this out that it is guaranteed that data can only be read out or modified when the card is situated at a distance from the terminal coils as predetermined by the geometry of the coil arrangement in the card relative to the geometry of the coil arrangement in the terminal (i.e., spacings, stereo bases, stereo card separation point).
FIG. 4a illustrates card coils KS.sub.-- L and KS.sub.-- R, which receive the quadrature-phase signals of the terminals TS.sub.-- L and TS.sub.-- R, have their outputs applied to a card electronics E1 wherein binary modulated signals DKS.sub.-- L, DKS.sub.-- R arise. From these binary modulated signals, electronics E2 generates a signal PHS that, on the basis of its logically true (TRUE) or, respectively, false (FALSE) binary condition, images a phase modulation transported in the signals of the DKS.sub.-- L and DKS.sub.-- R that is usable for the operation of the component parts of the card electronics critical to the invention.
A more detailed block circuit diagram corresponding to FIG. 4a is shown in FIG. 4b and uses standard combination logic elements based on DIN 40700. In particular, the input of a phase limit value generator is additionally shown. In addition, further terminals are reserved for half-spaces that are available.
FIG. 5 illustrates the consequences of charging the two transmitters TS.sub.-- L and TS.sub.-- R with quadrature phase. It is a partially-quantitative development of FIG. 2 and uses like symbols introduced therein. The flux lines are again drawn semi-bold face and also with thin lines. Also, broken-line field strength lines have been added.
First, block circuit symbols show how the phases arise in a known way. A generator generates a sine signal that is oppositely shifted by 45.degree. in two phase shifters. The phase immediately at the output of each phase shifter is respectively unmistakably identified at the left as "-.pi./4" at TS.sub.-- L and, at the right, as "+.pi./4" at TS.sub.-- R.
The illustration of the signal in the phase domain is applied as a AC vector--standard in alternating current theory--as a respectively small symbol immediately on the appertaining feeder to the respective transmitter element. Proceeding therefrom, FIG. 5 shows the spatial response of the AC vectors as a consequence of the addition respectively dependent on phase and magnitude of the two field components but omits the resultant magnitude. Only the phase of the resultant AC vector with the end on a unit circle is shown because the magnitude of the AC vector is not relevant for the system as a result of foregoing the intensity.
When viewing FIG. 5 the AC vectors should not be confused with field vectors. It was already defined in the preconditions regarding FIG. 2 that the field vectors of transmitter and receiver reside parallel to one another and perpendicularly in the figure. Only the vertical components of the location-dependent field vectors induce signals in the receivers. The alternating flux AC vectors of these vertical components are entered location-dependent here in FIG. 5.
Also, FIG. 5 shows the field in the unmodulated condition. In particular, assume the logical status is logical FALSE. Following ISO 10536, the data transmission ensues bit-serially quadrature-phase modulated. It is adequate for this purpose to place the field into the state logical TRUE as needed on the basis of a discrete phase deviation in order to contribute to the transport of logical bits in a way that is otherwise known. The transmitter does this by increasing, in a known manner, the positive phase "+.pi./4" to +3 .pi./4 by the addition of .pi./2 and by reducing the negative phase "-.pi./4" to -.pi./4 by subtraction of .pi./2. In FIG. 5 the abstraction of this procedure denotes that the field image is turned by 180.degree. within the plane of the drawing and otherwise continues to act unvaried. The signal PHS does not change stationarily in any way whatsoever due to this type of modulator and the locating method is therefore stationarily independent of the modulator. Transient disturbances due particularly to re-pulsation of energy stores at the change in logic state can be countered by known blanking methods or synchronous detectors, since the possibility of recovery of a clock that is free of phase shift and is location-independent and modulation-independent in the useful zone around the singular point is available for derivation from the difference signal.
The curves of the alternating fluxes of the terminal coils (known as TS.sub.-- L and TS.sub.-- R from FIG. 3) in the time domain are shown in FIG. 6 as DKS.sub.-- L, DKS.sub.-- R in the upper part. The curves are shown in the way they would appear given perfect channel separation after induction in the card coils KS.sub.-- L' and KS.sub.-- R' from FIG. 2, after the clamping of the lower half-wave and after the limitation of the upper half-wave. These binary signals are thus freed from the intensity and now only carry the phase. The quadrature phase may already be seen in the unmodulated condition, which is exclusively shown here. The various phases that are still unmodulated can be considered according to the attitude of the card coils corresponding to FIG. 2 and according to the initially rough interpretation in the legend of FIG. 3.
In an embodiment, the binary signals DKS.sub.-- L and DKS.sub.-- R within E2 of FIG. 4 are operated upon, for example, by an XOR gate in a means known as a phase detector. FIG. 7 illustrates signal curves that result therefrom. The type of signal evaluation is explained below.
The expanse of the stereo card separation area SCSA, wherein the stereo card separation point SCSP is located, is shown in FIG. 8. Dependent on the stereo base and on the generation of a specific signal PHS in conformity with the principles of the present invention, the stereo card separation area SCSA can be defined in terms of its expanse and determines the limits wherein a standardized card according to ISO 10536 can--without additional information about its attitude--separate a close coupling, relative to a transmitter, from a remote coupling. An embodiment of the present invention provides contact-free chip information carriers that contain at least two reception elements (KS.sub.-- L, KS.sub.-- R) such as inductor coils, capacitor plates, photoreceivers, microphones or other elements that are spatially separated from one another and are suitable for receiving two differently charged signals, particularly charged with a phase difference.
In one embodiment, the signals from KS.sub.-- L, KS.sub.-- R are edited for a second electronics E2 in a first electronics E1 so that a phase difference between these two signals can be electronically interpreted. In particular, the signals KS.sub.-- L', KS.sub.-- R' with 90.degree. phase difference are shown in FIG. 3. FIG. 4 represents a block circuit diagram of the electronics units E1, E2 with their inputs and outputs. The signals acquired from KS.sub.-- L, KS.sub.-- R and operated upon by E1 are shown in FIG. 6. DKS.sub.-- L, DKS.sub.-- R image the phase difference of the signals from KS.sub.-- L, KS.sub.-- R. Due to the use of a comparator having a zero threshold, the intensities have disappeared and cannot influence the operation as long as the intensity of both signals KS.sub.-- L and KS.sub.-- R is absolutely adequate in order to operate the zero-access crossing comparator disturbance-free (a known squelch circuit can resolve this problem in a known way). Other phase differences occur in FIGS. 4 and 6 due to different spatial relationships between KS.sub.-- L, KS.sub.-- R on the one hand and TS.sub.-- L, TS.sub.-- R on the other hand,
Electronics E2 should react to a discrete phase difference between DKS.sub.-- L and DKS.sub.-- R with an unambiguous, discrete signal PHS. Particularly for a phase difference of 90.degree. between DKS.sub.-- L and DKS.sub.-- R--in an information-free reference condition, FIG. 7 shows a signal referenced 1.DEX.sub.-- L/R that results. The 1.DEX.sub.-- L/R signal has a discrete pulse-duty factor of 1:1. Given a phase difference deviating from 90.degree., different pulse-duty factors are acquired with 2.DEX.sub.-- L/R and 3.DEX.sub.-- L/R. The pulse-duty factor is thus an indication for the phase difference and can be taken as an exemplary embodiment of the signal evaluation within the meaning of the present invention. The level of the output PHS can be acquired from the pulse-duty factor. Given deviation from the pulse-duty factor 1:1 in 1.DEX.sub.-- L/R, the level PHS can assume a new condition PHS'. To this extent, the exemplary embodiment is equivalent to the known phase detector having an XOR element and a subsequent low-pass filter.
As already proceeds from the descriptions of FIG. 2, an impressed phase difference between TS.sub.-- L and TS.sub.-- R is maintained with only limited geometrical conditions relative to TS.sub.-- L, TS.sub.-- R and, consequently, can be imaged therefrom. KS.sub.-- L, KS.sub.-- R must be located in this geometrical condition, since the received phase difference can otherwise not have the value impressed in TS.sub.-- L, TS.sub.-- R. When the intensity in the elements TS.sub.-- L, TS.sub.-- R is varied in an arbitrary way, then this has no influence on the limits of the shaded zones in FIG. 1, as was set forth in the description of FIG. 2. When the intensity in both elements TS.sub.-- L, TS.sub.-- R is simultaneously varied in terms of size and/or operational sign, then this has no influence on the phase-wise content (spatial response of the phase gradient) of these zones. Only differently constituted variations of the intensity can influence the content of the zones. However, even then the phase fields are only quantitatively distorted within their invariable limits but remain qualitatively employable.
In the present invention, the strength of the transmission power at the elements TS.sub.-- L, TS.sub.-- R does not influence the signal, i.e. the stereo base is assumed to be constant. The signal PHS indicates a spatial zone that can be measured in conformity with the present invention and is termed a stereo card separation area SCSA herein. The SCSA acquired in this way enables a separation between close coupling and remote coupling. An element is provided in an embodiment to automatically acquire the SCSA.
As an example, if a video camera were used to record the movements of a card in the proximity of the SCSA and if a registration and memory deposit of the chronological change of the signal PHS were present in the same card, then departure from the SCSA as recorded by the camera could be duplicated from the PHS signal changes registered and stored in the memory in the card.
An embodiment having an integrated signal processor can be selected for the blocks E1 and E2 in FIG. 4. In this case, the language for describing the hardware can be turned over to a compiler, with which the generating technique of the signal PHS, according to all known implementation steps, is located in the ROM of the processor as firmware.
The local zone wherein a transmitted phase difference is recognizable is also defined by the size of the phase difference of the transmitted signals at TS.sub.-- L, TS.sub.-- R relative to one another, in addition to being defined by the geometrical conditions. Given antiphase, the field is canceled in the distance. Usable components of the flux are present only in the proximity of the transmitters TS.sub.-- L and TS.sub.-- R. Given phase equality, the fields add up in the distance and consequently lead to an arbitrarily great range; however, a phase information for distinguishing between close/remote is not available. These two phase relations are unusable special instances. The alternating flux resulting from the superposition of the two fields generated by TS.sub.-- L and TS.sub.-- R always has a scalar AC vector; based on the reception location, it changes only magnitude and/or operational sign. It is binarily rotated. The phase gradient is usually zero in the space domain and, for instance, is infinite only at specific geometrical locations. The infinite gradient for the close/remote discrimination is then only of use when the stereo base of the receiver is only about half as large as that of the transmitter. However, "close" is interchanged with "remote" when the card is turned, i.e. KS.sub.-- L changes places with KS.sub.-- R. In both instances, the geometrical locations that are relevant lie within the triangle that is described by the singular point and the two transmitters in FIGS. 1 and 2. This is too close in the equiphase case and far too close in the antiphase case for use in an embodiment of the present invention.
In the case of the quadrature phase on the transmitters TS.sub.-- L, TS.sub.-- R, the entire spatial response of the phase gradient is continuous and differentiable because the orthogonal AC vectors of the two fields add up to an analogously rotated AC vector dependent on the local intensity (AC vector magnitude). The local phase gradient can be taken from a receiver KS.sub.-- L, KS.sub.-- R and can be processed in the described way to form a signal PHS. This is an optimum embodiment of the subject matter of the present invention. Attacks having phase deviating therefrom for the purpose of fooling the card about its position can only falsify the system status in the direction of the previously discarded phase equality of phase opposition and thus expose themselves to the locating problems that have already been discussed.
The apparatus graphically shown in FIG. 4 shows a preferred embodiment for optimum exploitation of this quadrature phase that was just described above. A comparator compares the analog signal PHS, which is proportional to the local phase, to what is referred to as a phase limit value (likewise analog) in FIG. 4, the latter being set such that it is conformally represented (i.e. mapped) in the locus domain onto the boundary between two half spaces of interest. When the card is located in one half space protectable operations are allowed; they are forbidden in the other half space. The binary signal following the comparator in FIG. 4 consequently states in which of the two half spaces the card is located. Meaningfully, the half space for allowing protectable operations is signaled by the logic condition "true" (TRUE) instead of conversely. As particularly shown in FIG. 4, namely, this signal can then be qualified in an AND element with further restrictions (in particular, further "half spaces", as well as abstract restrictions such as an electromechanical switch, particularly in an extremely simple case).
Further half space signals can be added to the logical qualification of the underlying half space signal in the AND element of FIG. 4 that has just been set forth in order to prevent half space positions that indicate a doubtful position of the card from permitting protectable operations in an optimally reliable way. Only when all of these half space signals simultaneously applied to the AND element are logically true, does the output of the AND element allow the protectable operation. This is the conformal mapping of the section of loci from the space domain onto the conjunction of the binary logic.
A few possibilities of adding space for improving the identification of position are unmodulated transmission with quadrature phase, including a sum signal and a difference signal; and quadrature-modulated transmission with quadrature phase, including a sum signal and a difference signal.
The method described here utilizes the interpretation of a phase difference. The intensity received at the elements KS.sub.-- L, KS.sub.-- R can be additionally interpreted--at least redundantly for safeguarding the identification of the receiver position. This intensity is suitable for demarcating the direction of the flux from the elements TS.sub.-- L, TS.sub.-- R but does not select a location zone because the received intensity, in addition to being dependent on the spatial origination of the card reception elements KS.sub.-- L, KS.sub.-- R with reference to the terminal transmission emits TS.sub.-- L, TS.sub.-- R, is also dependent on the intensity of the transmitted signal. Here, too, the absolute intensity of each channel can be fundamentally eliminated in and of itself, for example, by dividing the respective momentary value by an effective value. A usable locus for eliminating ambiguity is, in particular, a hyperbola (in the plane of FIG. 2) acquired by cross-division of the effective values of KS.sub.-- L, KS.sub.-- R. An amplitude modulation, however, is not usable because this is already used for the return channel according to ISO 10536.
The drop in field strength with the third power of the distance caused by a greater distance of the card from the transmission means is, basically, a natural limit for the operation. First, the load-modulated return channel according to ISO 10536 fails because the swing produced by the card no longer occurs in the terminal. However, the phase-modulated forward direction from the terminal to the card may still function at greater distances, so that an attacker can blindly impress information on the card from a distance without being worried about the reply from the card. It is particularly this possibility that is suppressed by the the present invention.
In an embodiment of the invention, the principles thereof can be used to control a heart pacemaker. Heart pacemakers can contain primary batteries or secondary batteries that are charged contact-free in order to maintain their function. Such devices should be controllable from the outside contact-free without other fields situated in the space being allowed to influence the function. When the principle of invention is used, functions of heart pacemakers can be controlled contact-free in a close zone, while precluding an influencing from a greater distance.
In an embodiment of the invention, the principle thereof can be used for access control. The remote transmission of data, for example in means of public transportation or in access control, intended by the card user is advantageous since the task of plugging the card in is eliminated. In order to preclude an unwanted interrogation, the remote transmission can be deactivated by actuating a switch (not shown) on the card.
When a card is basically configured for remote coupling (remote coupling beyond ISO 10536), then the momentary capability of the remote coupling can be decided by comparing the signal PHS to the limit value. A comparator handles the comparison in a known way and switches the capability of the remote coupling in the desired way. This switch can be bridged by the signal PHS because the card is then situated in the close region of a terminal. A remote bridging of the switch can be inventively precluded in this way.
When a card has the elements conforming to the invention, then the card can generate a signal PHS upon recognition of a pre-set phase difference that can be used for inhibiting or enabling card functions and which thus only enables the use of specific card functions when the card is located in a predetermined proximity relative to a terminal. The corresponding location area is defined by the geometrical arrangement of the reception elements not by the intensity of the surrounding field. The limit value to be set in the card can be set to conditions of the terminal.
It is conceivable that, despite the known disadvantages, a card for remote transmission has an on/off switch on the card for the purpose of manual operation. The function of this switch can be connected to the signal PHS on the basis of a combination. For example, the function of the switch can be modified given the presence of the card in the stereo card separation area.
Although other modifications and changes may be suggested by those skilled in the art, it is the intention of the inventors to embody within the patent warranted hereon all changes and modifications as reasonably and properly come within the scope of their contribution to the art.

I've got two new casting decisions to tell you about, one part is for Jada Pinkett Smith and Shakur's mother Afeni Shakur.
Hello, Jana here,
David Koechner, is much more than the perfect guy to deliver a huge laugh or to set someone else up for the delivery. He's got a face you instantly recall in the midst of a good memory of a great scene. Actor, director, writer, producer and all around funny man. He's got tons of credits up his sleeve including the blockbuster hilarity inducing 'Anchorman' and it's sequel. He's recently had director co-writer Christopher Landon pitching woo at him for Paramount's upcoming horror-comedy about Boy Scouts who try to fend off a zombie attack, and protect their Girl Scouts, in their small town. 'Scouts Vs. Zombies' sees Koechner joining a cast comprised of Joseph Morgan ('Master and Commander', 'The Vampire Diaries', 'Immortals'), Tye Sheridan ('The Tree of Life', 'Mud') , Logan Miller ('Growing Up Fisher', 'Night Moves'), Andy Fickman, Todd Garner, Bryan Brucks and Betsy Sullenger.

Barbie Kligman ('Private Practice', 'The Vampire Diaries', 'CSI: NY') is writing, executive producer and showrunner along with EP's Tracey Robertson and Nathan Mayfield. Charles McDougall ('Sex and the City', 'The Office') is set to direct the pilot. Ryan Phillippe has signed on to play the patriarch who becomes the prime suspect in the murder of a young boy when he finds the body. Juliette Lewis is the newest addition to the cast and will play Andrea Cornell, the unflappable, somewhat formidable detective conducting the investigation into the slaying of 4 year old Tom Mullen who has her sights set on Ben (Phillippe), the loving father who found the boy's body.
Jana B. here,
I love network television in the fall. The big reason for that is the introduction of dozens of new pilots hopeful of being selected for series orders. One of the hottest networks is The CW. While still relatively young, The CW zeros in on the 18-34 age-demographic with proven success. Fresh story telling and unique scenarios are their calling cards. Hoping to join the ranks of such proven program favorites like 'Supernatural', 'The Vampire Diaries' and 'Smallville' are several projects.
Jana B., Here…
You can't bottle lightning and you won't likely see it strike the same place twice. Yet, television networks seem to be banking on just that improbability becoming the mainstay instead of the rare event it really is. Sadly, those of us that love truly original story lines are running out of things to watch. The silver screen has been a big culprit of this with the barrage of re-makes from successful movies barely 20 years old and mediocre tv shows that have earned the big screen treatment. I always hoped the small screen was safe since spin-offs never seem to do as well as the predecessor. Of course there are exceptions to this rule, but they are few and far between. I'm now taking bets on which of these proposed and shows in the works will make it through their first full season. I'm kidding, I'm not a bookie. Seriously, though…I'll give you excellent odds.

Opinion Column: Game of Thrones isn't great this season and it's ok to admit that!
Dan M., here….
Game of Thrones isn't great this season and its ok to admit that. Come to peace with it. Embrace it. It is still the best looking show on television, with some of the most complicated characters ever seen on screen or page. Even this season the show can reach heights that no other show on television has ever touched, ever. But gone are the reflective moments, the social commentary, the irony, and any emotion. Anyone can make a spectacle. Hollywood is never short on spectacle. You can have a movie with superheroes, giant robots, etc. and you won't find anyone with a pulse who won't admit that is kind of neat looking. But more often than not these big spectacles bomb or get trashed critically because there isn't one ounce of honest character development or storytelling. This is where Thrones finds itself.

This bluray was released over a month ago exclusively at BEST BUY. If you have not picked it up yet, then you can pick Blair Witch up anywhere tomorrow. While this bluray disc is the best Blair Witch has ever looked, it is far from being a demo in your home. Still tons of grain and just over all sloppy. But I believe this was the intent of the filmmakers. To make it look as real as possible. The sound isn't really that great on the disc. Those set aside, if you liked seeing this movie all those years ago, then this is a must pick up to re-live that time and the special features are pretty good.

Grindhouse: Special Edition (Blu-Ray)
It is about time we get these two films from Tarantino and Rodriguez in one release. And YES. YES. We will be getting all the fake trailers in this release of Grindhouse. Now I am a big fan of actual Grindhouse films and Tarantino and Rodriguez did an excellent job in re-creating the atmosphere and feel of this type of film. I cannot wait to sit down with some friends at midnight with tons of beer and food and watch these two films in a row.

Hard Candy (Blu-Ray)
This was another film that was released a while ago as a Best Buy exclusive. This film made me sweat. I was on the edge of my seat the entire film. One of the most tense films I have ever seen. If you have not seen this yet, I really do not want to give anything away, but seriously buy this film if you love uber tense movies. What a thrill ride. it stars Ellen Page from "Juno".

This a slasher/horror foreign film from France and it does not Disappoint at all. A huge twist ending and a whole lot of guts and blood are instore for you. A great addition to any horror collection and just in time for Halloween. Marie and Alexia are classmates and best friends. Hoping to prepare for their college exams in peace and quiet, they decide to spend a weekend in the country at Alexia's parents' secluded farmhouse. But in the dead of night, a stranger knocks on the front door. And with the first swing of his knife, the girls' idyllic weekend turns into an endless night of horror.

The Human Centipede (Blu-Ray)
I saw this film a few months ago. It really did not get a wide release in theaters. IFC put it on demand for a couple of weeks and I got a chance to watch it. WOW. It is a brutal torture film in which a mad scientist/doctor makes a "Human Centipede", by kidnapping innocent people and sewing his victims ass to mouth so they have one digestive track. This is a film to watch with others and watch their reaction. Much much joy. This is a must own for all you cinephiles out there. "During a stopover in Germany in the middle of a carefree roadtrip through Europe, two American girls find themselves alone at night when their car breaks down in the woods. Searching for help at a nearby villa, they are wooed into the clutches of a deranged retired surgeon who explains his mad scientific vision to his captives' utter horror. They are to be the subjects of his sick lifetime fantasy: to be the first to connect people, one to the next, via their gastric system, and in doing so bring to life 'the human centipede."

The Karate Kid 2010 (Blu-Ray)
12-year-old Dre Parker (Jaden Smith) could've been the most popular kid in Detroit, but his mother's latest career move has landed him in China. Dre immediately falls for his classmate Mei Ying—and the feeling is mutual—but cultural differences make such a friendship impossible. Even worse, Dre's feelings make an enemy of the class bully, and kung fu prodigy, Cheng. With no friends in a strange land, Dre has nowhere to turn but maintenance man Mr. Han (Jackie Chan), who is secretly a master of kung fu. As Han teaches Dre that kung fu is not about punches and parries, but maturity and calm, Dre realizes that facing down the bullies will be the fight of his life.

The Last of the Mohicans (Blu-Ray)
An epic adventure and passionate romance unfold against the panorama of a frontier wilderness ravaged by war. Academy Award winner Daniel Day-Lewis (Best Actor in 1989 for My Left Foot) stars as Hawkeye, rugged frontiersman and adopted son of the Mohicans, and Madeleine Stowe is Cora Munro, aristocratic daughter of a proud British Colonel. Their love, tested by fate, blazes amidst a brutal conflict between the British, the French and Native American allies that engulfs the majestic mountains and cathedral-like forests of Colonial America. What a gem of a film in high definition.

The Maltese Falcon (Blu-ray)
A beloved Bogart classic gets the high-def treatment. A gallery of high-living lowlifes will stop at nothing to get their sweaty hands on a jewel-encrusted falcon. Detective Sam Spade (Humphrey Bogart) wants to find out why – and who'll take the fall for his partner's murder. An all-star cast (including Sydney Greenstreet, Mary Astor, Peter Lorre and Elisha Cook Jr.) joins Bogart in this crackling mystery masterwork written for the screen (from Dashiell Hammett's novel) and directed by John Huston. This 1941 Academy Awards® Nominee* catapulted Bogart to stardom and launched Huston's directorial career – all with a bird and a bang.

A Nightmare on Elm St. 2010 (Blu-ray)
This remake of the beloved 1980's classic by Wes Craven gets the remake over haul and only somewhat disappoints. You get everything you want out of the film. Jackie Earl Haley plays Freddy and he does a good job at it and there are even some straight forward shot for shot remake scenes from the original. But what is missing or shall I say what is NOT missing. Listen, I do NOT want an "in my face" reason why Freddy is Freddy. I do NOT want to know when these characters are in a dream or not until creepy shit starts happening. And I want Freddy to be the same funny one liner Freddy, which I get but only in the end. Some stuff was done right and some stuff was not. Overall I still liked it, and will see another sequel if one gets made, but the original still is the best.

Rosencrantz and Guildenstern are Undead (Blu-Ray)
Rosencrantz and Guildenstern are Undead' is the debut feature film of Director Jordan Galland, who also penned the original screenplay, which finds the characters from Hamlet, a tip of the cap to Tom Stoppard, and a two thousand year conspiracy involving vampires and the Holy Grail. This just sounds BADASS! Must Get.
Secretary (Blu-Ray)
What a modern classic cult film this was. I love the fetish world and this films explores quite a bit of that. In an office setting no less. A true Love Story at heart. James Spader and Maggie Gyllenhaal star in the dark comedy Secretary. Praised as "daring, funny and quirkily erotic!" (Glenn Kenny, Premiere) and "sexy and highly stylized" (Gear magazine), Secretary is the story of Lee Holloway (Gyllenhaal), a young woman with a few strikes against her after a brief stay in a mental hospital, who accepts a secretarial position working at the law office of E. Edward Grey (Spader). The work seems normal at first, but somewhere between the typing, filing and coffee-making, Lee and her new boss cross the line of their professional relationship and enter into a Human Resources nightmare!

Splice (Blu-Ray)
I really liked this film. It was a very different take into the realm of sci-fi and horror. It is a bit awkward to watch, but I loved where this move took me. I have not seen it before done. Very good and highly recommended. Superstar genetic engineers Clive (Adrien Brody) and Elsa (Sarah Polley) specialize in splicing DNA from different animals to create incredible new hybrids. Now they want to use human DNA in a hybrid that could revolutionize science and medicine. But when the pharmaceutical company that funds their research forbids it, Clive and Elsa secretly take their boldest experimentation underground—risking their careers by pushing the boundaries of science to serve their own curiosity and ambition. The result is Dren, an amazing, strangely beautiful creature of uncommon intelligence and an array of unexpected physical developments. At first, Dren exceeds their wildest dreams. But as she grows and learns at an accelerated rate, her existence threatens to become their worst nightmare.
Troll 2: Nilbog Edition (Blu-Ray)
Labeled as the Best Worst Film Ever. Troll 2 does not have trolls in the entire film nor is it a sequel. If that does not capture you to want to watch this then I do not know what will. Disguised as friendly country folk, a pugnacious posse of people-eating trolls lures visitors to their town. But a family of four is about to discover this place is a real tourist trap…and they're the prey! Now, the no-good gnomes must be destroyed before the family gets flambéed…and the world becomes a buffet in this feeding frenzy of fear! A ridiculous good time.
That is it for this week. Stay tuned for next week.

To hear a pilot whale overture -- sound I (1198K)
and sound II (865K).
Also playing pilots -- sound III (1702K).
Pilot whales are one of the most common inshore species in Newfoundland,
especially when squid, their primary food, are plentiful. They can be seen as early
as May, and stay inshore as late as October. In winter, these whales are thought
to range from the Grand Banks as far south as North Carolina.
Group of pilot whales appearing on the sea surface.
Click here for mpeg movie (1295K).
There may have once been as many as 50,000 pilot whales in Newfoundland
waters. Whaling for this species in Newfoundland was done by driving groups
of animals ashore, and one year in the mid-1950s about 10,000 were killed.
Whaling was discontinued in 1972 because of decimated local stocks and poor
markets for the meat, which was typically sold to fur farms.
Female pilot whales mature at 6 years of age and a length of about 3.5 m. Males
mature much later when 12 years old and 5 m in length. Mature adult males,
which are generally larger than females, can weigh as much as 3 tons. At birth,
calves weigh slightly over 200 lbs. The are born after a pregnancy of 16 months,
and are weaned at around 20 months of age.
Pilot whales have strong social cohesiveness; it is rare to see a single individual.
Even when being driven ashore by whalers, they would stay together as a group.
Groups typically contain animals of both sexes and many different ages. The
males may compete for breeding privileges, forming a hierarchy that excludes
smaller males. Large assemblages may also be composed of smaller, close-knit
groups which are stable over time.
Pilot whales are some of the noisiest whales in Newfbundland waters. Their
group structure requires social communication, and they orient to prey objects
by echolocation. Vocalizations include a wide variety of whistles and clicks.
Occasionally, groups of pilot whales slowly swim ashore and beach them-
selves. Such mass standings are a natural phenomenon and have been observed
throughout history. The reasons for mass strandings are not understood. One
possibility is that some or all of the animals in the group are sick, or have parasites
that affect their navigational system. In many cases, strandings occur at gently
sloping, sandy beaches, which may distort the whale's sonar, making it difficult
for the animal to determine direction or depth. Some scientists have suggested
that mass strandings occur at sites where there are unusual magnetic fields. The
presence of bait very close to shore may also be a factor. It is probably best to think
of mass strandings like any accident where, rather than a single cause, a number
of factors probably contribute.

Trick.ly helps you share secrets
Trick.ly is a website that offers url shortening with a twist. Simple in concept, trick.ly gives you the option of adding a password to your shortened links enabling you to share the link publicly with a select few. But why would you want to password protect a link? Well here are a few ideas:
- Share an inside joke on the fly with friends in specific groups eg. twitter and facebook lists. No need to contact group members individually.
- Share user sensitive data with your team
- Share X-Rated pictures and articles with that special someone
- Get that message out with additional private info embedded in a password locked link
- Embed confidential data in a forum or social site and hold the world at ransom. When the time is write, give them directions to the link and password.
Many people might not find this concept practical or useful but its good to know that if the need arises you can use the feature.
How to use the feature:
- Insert url that you wish to shorten eg. http://shonari.net
- Enter any desired password (optional): eg. 'boo'
- Enter a clue if you want to have your desired target guessing away ;): eg. 'ghostly sound'
- Hit shorten and your url will be ready for use.
Here is the finished product, give it a try with the details above: http://trick.ly/30d
Try it yourself: http://www.trick.ly/
In my humble opinion adding an additional feature will make this service even more useful. Combining it with a quick note option with optional password will make sending secret notes back and forth a breeze. If you had that feature back at school, the teacher couldn't send you to detention for that less than savory note to your best friend in class. A simple text note could be created directly from the site with optional password and clue, the trick.ly url is generated and now you have a safe and easy way to deliver a note over public sources.
Also password enabled links should be date sensitive ie the link will expire in time specified by its creator. See where I'm going…a note with a self destruct timer. Sweet!

The Syrian war was not only a military, geographical and economic campaign but also a 'cultural' war 'systematically targeting' Syrian sites and heritage, according to the wife of Syrian President Bashar Al Assad, Asma al-Assad, who was speaking in Tekkiye Mosque complex in Damascus on Saturday.
Al-Assad made the comments on the side-lines of 'Shadows', an event held to celebrate the inclusion of shadow play as the first Syrian element in the List of UNESCO's intangible cultural heritage.
"It's a war against identity, belonging and roots but also on cultural heritage. It's clear that it is a systematic targeting of heritage and the destruction of sites during these eight years of war," said the Syrian First Lady.
A show acted out with handmade puppets behind a thin translucent screen, shadow play was ascribed in late 2018 by the Intergovernmental Committee for the Safeguarding of the Intangible Cultural Heritage as in need of urgent safeguarding.

Enabling Better Planning and Resource Management during Disruption
In 2017/18 there were 963 incidents of serious disruption (>1,000 delay minutes), which together accounted for over 118,000 PPM failures, 2 million delay minutes and 56,000 cancellations and significantly late trains.
Contingency plans - which offer pre-determined strategies for managing disruption and restoring operation to the planned timetable, maintaining safety, managing the customer experience and ensuring operational robustness – can limited by the availability of stock and crew resources, and by the competence of control staff to transition to and operate a contingent plan, and then removing the plan and restoring the full service.
RSSB is currently developing good practice guidance on contingency planning and resource utilisation during disruption, which is due to be published in the autumn. The first outputs of this work have been completed in early 2019 and are being piloted by Greater Anglia, Scotrail and Govia Thameslink Railway as part of the May 2019 timetable changes. This will be complemented by a toolkit to help operators implement better contingency planning and disruption management, including:
- A methodology for assessing the effectiveness of contingency plans and potential improvements to plans
- A toolkit to support better resource management during disruption
- A competency framework for control staff managing disruption
Get in touch if you would like to find out more and to register an interest in the launch of these resources.

Merricks House
Merricks, Victoria
While the opportunities inherent in a semi-rural, seaside context have been exploited to their fullest in this peninsula house, lessons learned from the effects of an often harsh coastal environment have necessitated a balanced response. Rather than orientate the house solely to the sea view, and the accompanying sea winds, a pair of curved rammed-earth walls arcs across the landscape to divide the site, and the building. To one side of this central spine, views to Western Port Bay are captured and framed; to the other, the vista is back into the slope of the land, away from prevailing winds. Here on this protected side, the house opens up to outdoor living spaces and a pool.
Internally, the subtly curved spine itself is a dramatic thoroughfare drawing the visitor in, past a series of smaller, refined volumes housing bedrooms, to a main living zone. The rammed earth walls, concrete floors and timber-lined ceiling provide a luxuriously raw and tactile backdrop to the spectacular natural surrounds.

Somehow the month of October is already upon us, and with it comes the cool weather of fall. This of course serves as a reminder of the much colder weather that will be here before we know it. With all of the great technology we have, there are plenty of gadgets that will make sure you keep plenty warm this winter. One such device is this Heated Traction Mat.
When it starts getting really cold, just lay this may down along your walkway, and turn it on any time it snows. This will keep your walkway snow-free without the need of a shovel. If you forget to turn it on before the snow starts, it will still melt it away at a rate of 2-inches per hour.
This seems like a great winter gadget, however, I find there to be a couple of problems with it. First, if your walkway slopes downward toward the street, all of the melted snow will run down and create a sheet of ice, which will only cause further issues. Second, at a price of $1,100 for a 2'x15′ mat, it's just not very cost-effective. You could probably pay a neighbor kid to shovel your walkway and driveway for many years at that price.

Long enough
A Reading Note
"…If a book is lost, then someone will write it again, eventually. That should be enough immortality for everyone," he said to me once when he was talking about the destruction of the Library at Alexandria.Manguel, With Borges, page 72
No book lasts forever, because no thing lasts forever. But many things—books included—last long enough.
