Age: 1 Year(s)
15 Years of Wunderlandit's our Birthday and we look back on 5479 wonderful days.
Dear friends and companions,
today 15 years ago we opened the doors to Wunderland. It is our birthday, so to speak, and we want to take this as an opportunity to say thank you look back a little bit – the celebration will have to wait until after the opening of our Italy section.
We are looking back on fifteen, almost fairytale-like, years. If somebody would have told us back when we opened Wunderland for the first time, that we would receive around 1.3 million visitors a year from all over the world and would one day belong to the most popular attractions in Germany, we would have surely thought they were crazy. Especially in the last few months before the opening we were constantly called nutcases and almost nobody believed that model trains could lead to success.
To be honest, despite all our optimism in the beginning, we were still scared as hell. On the first day we hoped for a long queue at the entrance, but only a few hundred guests actually came. Only on the following weekend salvation came with a queue leading far outside our doors. This was the beginning of a fairytale, which enables us to tinker with creative ideas every day.
And this is what we want to say thank you for. Since then we received almost 15 million visitors in Wunderland and this strong support is the reason we can focus on all our small playful details. Over 350 "Wunderlanders" are creating small things with lots of love and devotion. We can afford to play around without looking to closely at the figures and without following strict rules. For us, it is not about creating something in a set amount of time, but to tell great stories. This freedom surely is not always very efficient, but leaves us room for creative and loving details and ideas. We believe that love cannot be expressed with numbers. And we are well aware of the fact that we couldn't work like this, if not this many of you would come and visit us year by year. For this, THANK YOU and a small promise: When you reach the age of 15 you get closer to becoming of age and puberty makes you want to dismiss everything childish. We will stand against this and will ensure that playing around, tinkering and creating will always be our number one priority.
We are unbelievably thankful for the last 5479 days and are hoping for many more to come.
Thank you for your wonderful support!
Your Wunderland Team

Unfortunately, I have no photo, so here is my best description: - Fairly large (about 20 inches deep, about 15 or 16 inches wide - it was deeper than it was wide) - Matte black leather - Had vertical seaming, perhaps lightly quilted (A bit like a Chloe Bay) - 2 handles; short enough to be hand held or in nook of arm, long enough to be carried on the shoulder It reminded me a bit of Chloe and YSL, but I have no idea if it actually was either of those brands. If anyone has any ideas, let me know!

This application is a continuation-in-part of copending application Ser. No. 358,310, filed May 26, 1989, now U.S. Pat. No. 5,012,236 entitled "Electromagnetic Energy Transmission and Detection Apparatus," assigned to the assignee of the present invention. This application is also related to two copending applications both assigned to the assignee of the present invention, entitled "Impedance Matching Coil Assembly for an Inductively Coupled Transponder" Ser. No. 4000,600 filed Aug. 30, 1989 and "Method and Apparatus for Producing a Subcarrier Signal for Transmission by an Inductively Coupled Transponder" Ser. No. 420,798 filed Oct. 12, 1989.
1. Field of the Invention
The present invention relates generally to inductively coupled electromagnetic energy field transmission and detection systems, such as a transponder in combination with an interrogation system, and more particularly to a method and apparatus for modulating and detecting an inductively coupled transponder subcarrier signal.
2. Brief Discussion of the Prior Art
Many objects, such as houses, pets and cars, require some means of identification. Many prior art methods of identification have required visual interrogation of the identifying medium to extract the identification data, such as reading numbers on houses, license plates on cars, and collar tags or brands on animals. Electronic identification tags have also been created, which can be associated with the object and electronically communicated with at a distance, such as the electronic sensing and actuator systems shown in U.S. Pat. Nos. 3,732,465 and 3,752,960.
The systems described in those patents are comprised of an active element, having a single transmitting and receiving coil, which operates by transmitting an electromagnetic field within the proximity of a passive electrical circuit, thereby inductively coupling the coil with the passive circuit. The passive circuit operates to create a characteristic change in the transmitted electromagnetic field that can be detected by the electronics associated with the receiving coil and used to trigger some mode of operation for the system. Although such systems remove some of the restrictions associated with the previously described visual identification systems, such systems are really nothing more than electronic keys, and actually convey less information to the active element than does a visually inspectable tag.
More sophisticated electronic systems use an exciter coil to transmit a high intensity electromagnetic energy field in the proximity of an electronic tag or transponder. The transponder is energized by the electrical energy inductively transferred by the transmitted magnetic field and is made operative to output a modulated identification signal which can be detected by an inductively coupled receiving coil proximately located at the exciter coil. The passive tag or transponder element of many of these devices, such as that described in U.S. Pat. No. 4,262,632, includes a coil which receives electromagnetic energy from a transmitted interrogation signal and retransmits an identification signal developed by the identification circuitry associated with the transponder. Electrical control circuitry within the transponder converts and rectifies the energy received from the transponder coil and develops a dc power source for use in operating the transponder's identification circuitry.
Transponders which utilize a sufficiently large capacitor or resident power source, such as a battery, are able to transmit identification signals over fairly large distances, from a few yards to thousands of feet. However, in certain applications, such as identifying small animals, the size of the sealed packaging required to house the battery or capacitor may be too large for the intended use.
A great amount of effort has been expended to develop a truly passive transponder, which will do more than simply operate as an electronic key. A transponder which can be safely implanted within livestock and interrogated from a practical distance would help to reduce problems associated with certain regulations being implemented by the European Economic Community that will require all livestock to be separately identified.
One effort to create such a transponder resulted in the syringe-implantable transponder of European Patent No. 258,415. This patent and other related patented systems, such as U.S. Pat. Nos. 3,859,624, 3,689,885, 4,532,932 and 4,361,153, disclose passive elements which operate in real time and therefore do not require any type of significant energy storage means. The transmitting and receiving units of these systems, which are often referred to as interrogators or readers, typically include either a single, dual or triple coil arrangement, which is used to both transmit a high intensity electromagnetic field in proximity of the identification unit and receive an identification signal retransmitted by the transponder in proximity of the reader coils of the interrogator.
The detection range of such systems is typically very restricted since the strength of the electromagnetic field produced by the transponder drops by 1/d5 at the receiver, where d is the distance between the receiving coil and the transponder coil, as the interrogator is moved away from the transponder. In fact, it has been calculated that at distances of 6 to 8 inches the strength of the magnetic field carrying the identification signal from the transponder, in devices similar to that described in the European Patent No. 258,415, is only an estimated one billionth the strength of the magnetic field carrying the interrogation signal to the transponder. Hence, the interrogator must normally be placed in very close proximity to the transponder in order for the identification signal to be detected. This limitation, of course, greatly restricts the utility of such devices, since not all objects may be so closely approached in order to be read.
Although the specification of European Patent No. 258,415 states that the system disclosed therein is operative to detect the retransmitted signal at distances on the order of inches, it has been found that devices constructed in accordance with that specification are actually incapable of obtaining such a range and are generally only effective when positioned within about an inch of the transponder. An identification device which is limited to operation within such a small range is of limited usefulness, especially when it is to be used to identify large or wild animals or other objects which cannot be readily approached.
If a transponder system is to be expected to maintain a greater reading distance, a number of different characteristics of the system must be considered. To increase or maintain a certain reading distance, the interrogator's ability to detect the identification signal transmitted by the transponder must be enhanced. A limitation restricting the reading distance of the transponder system is associated with the strength of the signal transmitted from the transponder to the reader. Hence, it is not only important to assure that an efficient inductive couple exists between the interrogator and the transponder, so that the transponder receives as much energy for operation as is possible, but it is also important to maximize the strength of the signal transmitted from the transponder to the interrogator.
Prior art transponder systems not only generally fail to provide for an efficient coupling between the interrogator and the transponder, but also fail to maximize the strength of the transponder signal. One reason prior art systems do not maximize the transponder signal is because the physical and electrical configurations of the interrogator's transmitting and receiving coils require that the frequency of the transponder signal be significantly different from that of the interrogator signal, thereby limiting the frequency and amplitude of the subcarrier signal. For example, U.S. Pat. No. 3,689,885 states that "[i]t has been found that by having the carrier time-base signal at a comparatively high frequency such as, for example fz =450 KHz, and the electromagnetic power field at a lower frequency, for example, f1 =50 KHz, interference between the electromagnetic coded information field and the electromagnetic power field is minimized." Col. 7, lines 11-17.
The efficiency and speed of many of the prior art transponder systems is also restricted by the type of modulation technique used to modulate the subcarrier. Many prior art systems use frequency-shift-keyed modulation for modulating the transponder's subcarrier, which generally requires fairly complex circuitry and which severely limits the data transfer rate of the subcarrier. U.S. Pat. No. 3,964,024 discloses a transponder system which utilizes phase-shift modulation for modulating the subcarrier, a technique which reduces the complexity of the circuitry required in the transponder, generally enhances the efficiency of the band-width, and increases the data rate of the subcarrier. However, this modulation technique requires that the transponder be equipped with two separately located coils, one for receiving power from the interrogator and one for transmitting the identification signal. In addition, since the data bit shifts high or low each time a phase change occurs, this technique does not anticipate a change in the orientation of the transponder resulting in a phase shift of the incoming signal or the transmitted signals.
Hence, a need has arisen for a transmission and detection system which can simultaneously transmit a high energy magnetic field, sufficient to power the transponder unit, and detect a localized retransmitted magnetic field at greater distances and with greater reliability.
It is therefore an object of the present invention to provide a novel electromagnetic field transmission and detection system which can simultaneously transmit a high intensity magnetic field and detect a localized low intensity magnetic field.
Another object of the present invention is to provide a novel electromagnetic field transmission and detection system which can accurately detect a localized low-intensity magnetic field in the presence of a high-intensity magnetic field, or other uniform electromagnetic interference or noise.
A further object of the present invention is to provide a novel electromagnetic field transmission and detection system which is capable of accurately detecting very low-energy magnetic fields within a range of at least 6-8 inches from the low-energy field transmission source.
A further object of the present invention is to provide a method and apparatus for modulating the subcarrier signal transmitted by the transponder so as to maximize the amplitude of that signal.
A still further object of the present invention is to provide a method and apparatus for modulating the subcarrier signal transmitted by a moving transponder so to accurately detect that subcarrier with the interrogator.
Briefly, a preferred embodiment of the present invention comprises a transponder system including a transponder and an interrogator having a transmission coil for producing a high-intensity electromagnetic field for inductively powering the transponder and two receiver coils for receiving a low-intensity electromagnetic field reradiated by the transponder. The transmission coil includes one or more conductive windings circumscribing a substantially polygonal volume of space. The receiver coils are diametrically disposed opposite one another within the volume space of the transmitter and are electrically connected to each other in a differential circuit relationship, the output of which is at a minimum when the two receiver coils receive approximately equal quantities of energy and is at a maximum when one of the receiver coils receives more electromagnetic energy from the transponder than the other receiver coil. The transponder uses a coil to derive both a power source and a clock pulse from the high-intensity field for powering and driving an identification circuit. The transponder's identification circuit then operates to divide the frequency of the clock pulse by 8 to drive its memory array and logic network so that a new data bit is clocked out every 16 cycles of the carrier frequency. The memory array is constructed to produce a new data bit on the rising edges of its input clock pulse. This results in an effective divide by two stage internal to the memory array, which results in the output of a new data bit every 16 cycles of the carrier. The same clock pulse is then used to generate the subcarrier which is at 1/2 the frequency of the carrier. The choice of 1/2 the carrier frequency as the subcarrier frequency maximizes the amplitude of the transmitted subcarrier. This subcarrier is then phase modulated by the output of a logic network so that one bit is encoded every 8 cycles of the subcarrier. This corresponds to one bit every 16 cycles of the carrier. The transponder also includes a double pulse lockout circuit which prevents rapid consecutive short-outs of the transponder's coil.
These and other objects of the present invention will no doubt become apparent to those skilled in the art after having read the following detailed disclosure of a preferred embodiment which is illustrated in the several figures of the drawing.

FIG. 4 is a partially-broken, perspective view of an alternative embodiment of the transmission coil and receiving coils of the present invention;
FIG. 5 is a diagram schematically illustrating a transponder assembly circuit in accordance with the preferred embodiment of the present invention;
FIG. 6 is a diagram schematically illustrating an interrogator/receiver circuit in accordance with the preferred embodiment of the present invention;
FIG. 7 is a timing diagram illustrating the relationship between the modulation waveforms present at various locations in the transponder and at various locations in the interrogator/receiver;
FIG. 8 is a timing diagram illustrating a typical bit sequence of a bit stream modulated in accordance with the preferred embodiment of the present invention; and
FIG. 9 is a diagram schematically illustrating the full-wave bridge rectifier of FIG. 5.
FIG. 1 illustrates a box car 10 travelling along rail lines 12 so as to pass along the front side of an interrogator or reader 14. Attached to the front of the box car is an identification box 16, which contains a transponder device in accordance with the preferred embodiment of the present invention, which will be further described with subsequent reference to FIGS. 5 through 9.
This identification device is positioned so as to pass within close proximity of the reader 14, which contains a transmitter coil 20 for transmitting a high-intensity electromagnetic field to the identification box and two receiver coils, shown generally as 22, for receiving the low-intensity electromagnetic field retransmitted by the transmitter of the identification box 16. A generator 18 supplies power to the transmitter coil to produce the high intensity electromagnetic field. A display and storage device 19 receives the output of reader 14 for storage and display of the content of the identification signal contained therein at display 21.
It should be noted that although the reader 14 is shown in communication with a passive identification device for purposes of the present invention, the electromagnetic transmission and detection apparatus of the present invention could be utilized in any of a number of applications where it is necessary to accurately detect a low-intensity electromagnetic field in the presence of uniform high-intensity electromagnetic fields.
The operation of the reader 14 may be better illustrated with reference now to FIG. 2, which illustrates transmitter coil 20 and the two differential receiver coils 22 of the preferred embodiment of the present invention. The number of windings utilized to create these coils, as well as the shape of the coils, can vary significantly. In general, the coils are substantially polygonal in shape, wherein a polygon is defined to mean a figure having many sides and a circle is assumed to be comprised of numerous straight lines rather than a true circle. Hence, the windings of the coils circumscribe a substantially polygonal volume of space, and the large outer transmitter coil 20 of the reader is generally comprised of about 20 turns of copper wire 24 wound in a polygonal manner so as to create a coil having a diameter, or polygonal diameter, of about 5 to 6 inches.
In all embodiments, the transmitter coil 20 and differential receiver coils 22 are ordinarily affixed to a suitable nonconductive support structure so as to be positionable as shown in FIG. 1. Support surfaces, such as the type required to support the coils of the present invention, are well known in the art, i.e., hand-held pistol-shaped scanner structures and wand-like antennas or scanner structures, and can be constructed so as to support the coils in any of a large number of different configurations. As will be noted below, many of the alternative embodiments of the present invention will require a support structure constructed in a manner different than that depicted in FIG. 1. In this regard, it is only important to note that the support should be constructed from such a material and in such a manner so as to not significantly interfere with the passage of electromagnetic energy to or from the coils.
When sufficient power is supplied to the transmitter coil 20, such that there is more electrical energy present in the coil than can be dissipated by the resistance of the coil, substantially toroidal-shaped electromagnetic energy fields, such as the flux fields 26 and 28, will be produced. Although the electromagnetic flux fields 26 and 28 are three-dimensional in nature, circumscribe the polygonal volume of the transmitter coil, and are not bounded within the defined limits depicted in FIG. 2, these electromagnetic flux fields will be illustrated by dashed lines 26 and 28 for the sake of simplicity. It should also be noted that the basic shape of the electromagnetic flux fields will be varied depending on the positioning of the differential receiver coils 22 with respect to the transmitter coil 20, as further described below.
When a passive identification device, such as the transponder assembly 30 of the identification box 16 is within the transmission and power range of the transmitter coil 20, some of the energy contained within the transmission fields will be transferred to the transponder assembly 30 through inductive coupling. The voltage extracted by the transponder's receiving coil (not shown in FIG. 2, but shown in FIG. 5) from the transmission field can then be used to power the electronic identification circuitry of the transponder, and in turn cause a modulated identification signal (in the form of current) to flow back through the coil of the transponder. Since the quantity of energy created by means of the inductive couple is small, and a certain quantity of that energy is utilized to operate the electronic circuitry of the transponder, the transponder coil is only capable of retransmitting a very low-intensity electromagnetic field of a highly localized nature.
The differential receiver coils 22 are comprised of two substantially polygonal coils 32 and 34, which are electrically connected to one another in a differential circuit relationship such that the electrical signals induced within the coils by electromagnetic energy are subtracted from one another so as to form a differential output signal. A schematic illustration of the differential coils 22 is shown in FIG. 3.
Receiver coils 32 and 34 are disposed within the volume space of the transmitter at significantly separated points. Preferably, the receiver coils and the transmitter coil are co-planar and the receiver coils are disposed in diametrically opposite positions. Since the receiver coils are positioned within the volume space of the transmitter coil, both receiver coils share a linking relationship with the flux fields 26 and 28. It is preferable to have the receiver coils diametrically opposed so that there is assurance that the receiver coils will be linked with substantially identical portions of the flux field, so that when the output of the receiver coils are subtracted, the difference will be close to zero.
It is also desirable to separate the receiver coils by some significant distance so that both receiving coils will not receive equally intense transmissions from the transponder. Since the strength of the transponder field typically drops off at the rate of 1/d5 at the receiver coils, separating the receiver coils will help to assure that the energy of the transponder field is primarily only received by one receiver coil. Naturally, the differential receiver coils will work if disposed in positions that are not diametrically opposed, and therefore not separated by as large of a distance. Thus, as long as the receiver coils are not positioned adjacent to one another, there should be some significant difference in the energy received by each receiver coil from the transponder.
It should also be noted that because of the related positions of the receiver coils, both coils would also generally receive approximately equal levels of substantially uniform interference energy created by other nearby transmission sources. The positioning of the receiver coils 22 within the transmitter coil 20 is an important aspect of the present invention, in that it allows the presence of the substantially equal and opposite transmission fields, together with other substantially uniform magnetic fields, to be cancelled by the differential nature of the two coils. Hence, by differentially electrically connecting the receiver coils so as to subtract the output signals of the individual coils from one another, it is possible to produce a combined output signal which has a near zero voltage amplitude when the two coils receive approximately equal quantities of energy, and a maximum voltage amplitude when one of the coils receives more energy from an electromagnetic field than does the other receiver coil.
Alternatively, it may also be desirable in some instances to modify the range or area covered by the transmission and detection fields of the reader 14. Possible methods of doing this would be to modify the shape or physical configurations of the receiver coils, move the receiver coils away from the plane of the transmitter coil, or rotate the receiver coils by some angle, such that their central axes are no longer parallel to the Y-axis of the transmitter 20.
It is important to note, however, that when the receiver coils or the receiver coils position's are modified in any such manner, the electrical symmetry of the reader system must be maintained such that more of the energy of the transponder field can be intercepted by one receiver coil than the other receiver coil, or else the differential coils will not be able to accurately detect the presence of the transponder. It is also important to note that in the event that modifications cause the receiver coils to be linked with flux fields of different or variable intensities, the physical or electrical characteristics of the receiver coils can correspondingly be modified, such that even if the receiver coils are not symmetrical with respect to the energy received, the differential output signal can still be zero when both coils are exposed to substantially uniform fields.
When the reader is configured as shown in FIG. 2, it is known that the reader 14 can accurately detect the presence of the transponder 30 at distances of up to at least 8 inches away. Once again, this increase in detection range over the prior art relates to the reader's ability to cancel out the relative presence of all but the transponder field when that field is primarily detected by only one receiver coil. The ability of the reader 14 to detect the transponder assembly 30 at such distances is also enhanced by the transponder assembly and modulation technique of the preferred embodiment of the present invention, as will be described below.
With reference to the particular arrangement of the various coils depicted in FIG. 1, the transponder 30 is positioned so as to receive the magnetic field generated by the transmitting coil 20. As previously stated, the strength of the electromagnetic field 38 retransmitted by the transponder is so small that it is effectively incapable of being detected by the transmitter coil. The transponder field 38 is, however, within the detectable range of the receiving coil 34. This is true because when the difference between the output of coil 32 is taken from the output of coil 34, the amplitude of the combined output signal will be greater than zero volts by an amount which corresponds to the energy transferred by field 38, thereby indicating the presence of the transponder and allowing for detection of the modulated identification signal contained within the field 38. In other words, the placement of the two receiver coils within the cylindrical volume of space of the transmission coil creates a high sensitivity to the transponder field and a low sensitivity to the transmitter field.
In order to be sensitive to the small transponder field, the receiver coils 32 and 34 should be formed from a sufficiently large number of turns of wire, i.e., 600 turns, so as to be sufficiently sensitive to the transponder field. The polygonal diameter of the two receiver coils should also each be smaller than the diameter of the transmitter coil, although this is not an absolute requirement if electrical symmetry is maintained. In the preferred embodiment, the receiver coils 22 are each approximately 20% of the diameter of the transmitter coil. Hence, when the diameter of the transmitter coil is 5-6 inches, the diameter of the receiver coils should be approximately 3/4 to 1 1/4 inches.
An alternative embodiment of the present invention is depicted in FIG. 4, in which the two receiving coils 132 and 134 are more or less placed on top of one another, so as to be substantially, coaxially positioned along the central axis of the transmitting coil 20. Since the transponder 30 can only be located on one side of the transmitting coil 20 at any one time, the energy of the transponder field 38 will generally only induce an electrical signal in one of the receiving coils and not the other. Because of the substantially symmetrical positioning of the receiving coils 132 and 134 about the transmitter coil 20, the receiving coils will link with substantially identical portions of the flux fields 126 and 128. Hence, the differential coil effect of the two receiving coils will allow the low intensity magnetic field of the transponder to be detected despite the presence of the high intensity transmitter fields.
It is anticipated that the two receiving coils of the present invention could also be shaped, disposed and oriented in a number of other shapes and positions within the volume space of the transmitter coil and achieve the differential detection effect described in reference to the preferred and alternative embodiments.
Although the differential receiving coils 22 of the present invention can extend the range over which the transponder assembly's signals can be detected, this range can be further extended, or at least maintained, if the strength of the transponder field 38 is increased. Since it is desirable to increase the strength of the transponder signal without increasing the size or complexity of the transponder assembly, various means, which are unknown in the prior art, must be developed to derive such power. One such means can be demonstrated with reference now to FIG. 5, which schematically illustrates a transponder assembly circuit 30 in accordance with the preferred embodiment of the present invention.
The transponder 30 is primarily comprised of two parts, a coil 202 and an integrated circuit containing the electronic components that make up the remainder of the transponder. When the transponder 30 is brought within range of the interrogator 14, a current is induced to flow through the turns of the coil 202, thereby creating an AC voltage across the turns of the coil. This AC voltage is then input to and rectified by the full-wave bridge rectifier 204, the operation of which will be further explained with reference to FIG. 9, to produce the positive DC voltage Vcc and the reference voltage Vss.
Node 206 denotes the reference point at the "clock side" of the bridge. This node also allows this same AC voltage to be split-off and used as an input to the clock recovery circuit 208. The other side of the bridge is referred to as the "FET side" because of the presence of the N-channel FET 210, the function of which will be further explained below. The clock recovery circuit 208 generates rectangular clock pulses from the sinusoidal waveform of the AC voltage input for driving the remainder of the circuit.
A frequency divider 212, comprised of a chain of toggle flip-flops configured as a ripple counter, divides the output of the recovery circuit by eight. Since the preferred carrier frequency of the transmitting field is 134 KHz, and the preferred subcarrier frequency is 67 KHz, as will be further explained below, dividing the clock pulses by 8 causes the memory array 214 and the logic network 216 to serially clock out a new data bit every 16 cycles of the carrier frequency. This in turn corresponds to a possible phase shift every 8 cycles of the 67 KHz subcarrier. Hence, the bit period of the subcarrier is eight 67 KHz cycles long, or 119 microseconds, which results in a data transmission rate of 8375 bits per second.
The memory array 214 contains 64 bits of data (although larger arrays are also possible) which are used to identify the particular transponder in which the memory array is installed. The data bits output by the 64 bit memory array 214 are fed to the logic network 216, which toggles the position of the phase select switch 218 in relation to the flip-flop 220 whenever a logic "0" is shifted out of the memory array 214. The flip-flop 220, driven by the clock pulses output by the clock recovery circuit 208, is used to phase modulate the data bits output by the logic network 216 at the subcarrier frequency of 67 KHz. When the phase select switch 218 is moved from Q to Q-bar by the logic network, one 67 KHz pulse is skipped, causing a 180 degree phase shift in the gate drive signal of the FET 210. Conversely, when the phase select switch 218 is moved from Q-bar to Q, a pulse is added to the gate drive signal in order to shift the phase of the subcarrier in the opposite direction.
The N-channel FET 210 is operative to periodically short out the "FET side" of the bridge in accordance with the phase of the 67 KHz gate drive signal in order to modulate the field surrounding the transponder coil 202 with the desired information. Adding a pulse to the gate drive signal would thereby cause the FET 210 to short out the bridge rectifier two 134 KHz cycles in a row. Because power to the transponder circuitry is obtained from the coil 202, and shorting out the bridge prevents the transponder from receiving power over the period of the short, allowing the FET 210 to short out the coil 202 for two cycles in a row would cause the transponder's power to drop below acceptable levels. To avoid shorting out the bridge for an extended period of time, a double pulse lockout circuit 222 is added to remove this extra pulse from the gate drive signal input to the FET 210. Hence, this extra pulse is swallowed by the pulse lockout circuit 222 and will not be present in the actual waveform input to the FET 210. Although pulse lockout circuits are used in many different types of technology, the use of such a circuit in the preferred embodiment is an important feature of the present invention because it allows a single coil to be used to both power the circuit and transmit its output, thereby eliminating the need for separate coils as taught by the prior art.
An additional distinguishing feature of the present invention is the manner in which the subcarrier signal is phase modulated by the digital data stored in the memory array 214. It is important to note that the phase of the 67 KHz subcarrier changes when a logic "0" is transmitted, but does not change when a logic "1" is transmitted. When a logic "0" is assigned to one phase and a logic "1" is assigned to the other phase, such as is taught by the prior art, a missing bit or phase change, i.e., resulting from a realignment in the orientation of the transponder and interrogator, can cause a misinterpretation of the data being transmitted. The phase modulation technique of the present invention prevents the erroneous interchange of logic "l's" and "0's" which can occur in prior art systems because the present invention only watches for chances in the absolute phase of the subcarrier and not the absolute phase as taught in the prior art. Hence, the absolute phase of the received signal can vary as the interrogator moves relative to the transponder and not effect the system's ability to accurately read the transponder's identification data. This modulation technique will be further explained below with reference to FIGS. 7 and 8.
A further additional feature of the present invention relates to the frequency at which the subcarrier is modulated. As described with reference to the prior art, such devices typically modulate the subcarrier at one-tenth of the carrier frequency to make it easier for the interrogator to distinguish between the transmitted and received signals. Assuming the use of a 134 KHz carrier frequency in a prior art system, the main spectral components of that signal would appear at 13.4 Khz. Hence, the energy carrying lower and upper side bands of the carrier signal would be calculated as 120.6 KHz (134-13.4) and 147.4 KHz (134 +13.4), respectively. Although modulating the subcarrier at this frequency simplifies receiver design by separating the subcarrier from the interfering exciter signal by a wider frequency spread, the energy dumped into both the 120.6 KHz and 147.4 KHz sidebands is now wasted energy because the receiver coil is not tuned to listen at these frequencies as well as the subcarrier frequency. In addition, a 13.4 KHz subcarrier signal cannot be modulated at the data rates available with higher frequency subcarriers. Since the data rate is an important factor in determining the code reading time, the data rate available is an important consideration, especially with respect to interrogating a moving transponder.
In the present invention, the subcarrier is modulated at one-half of the carrier frequency. The modulation of the coil current at 67 KHz produces three main spectral components, the subcarrier at 67 KHz and the upper and lower sidebands around the 134 KHz carrier signal. The upper sideband is at 201 KHz (134+67) and is wasted energy, but the lower sideband is at 67 KHz, which falls directly on top of the 67 KHz component of the coil current, thereby reinforcing and increasing the strength of the transmitted signal at 67 KHz. Since a stronger transponder signal directly relates to a greater reading distance, this increase in strength is extremely important. In addition, this subcarrier frequency allows for a high data transmission rate, thereby allowing the data to be read from the transponder numerous times before the transponder could possibly move a significant distance away from the interrogator.
FIG. 6 schematically illustrates an interrogator/receiver circuit in accordance with the preferred embodiment of the present invention. An exciter 230 drives the transmitting coil 20 with the 134 KHz carrier signal described above. The differential receiver coils 32 and 34 collect the modulated 67 KHz subcarrier signal emitted by the transponder 30 such that the large 134 KHz transmitting signal does not disturb the sensitivity of the receiver 232. The receiver circuit 232 is comprised of various stages, such as bandpass and notch filters, low-noise amplifiers and limiters, which operate to recover the phase modulated 67 KHz subcarrier collected by the receiver coils. The recovered signal is then applied to a comparator circuit 234 which "squares up" the sinusoidal receiver output by means of zero-crossing detection. this signal is then applied to the phase detector 236. The phase detector 236 is a flip-flop which receives a trigger from the exciter 230. Because the received signal from the comparator 234 is synchronous with, but not necessarily in phase with, the 134 KHz transmitting current, it is possible to easily trigger the phase detector so as to recover the changes in phase of the received signals. These phase changes are then logged by the microprocessor 238 which extracts the correct identification code of the transponder and outputs an identification data signal for storage or display as appropriate.
As stated above, the modulation technique and operation of the circuitry of the present invention can be better understood with reference to FIGS. 7 and 8. FIG. 7 is a timing diagram illustrating the relationship between the modulation waveforms present at various locations in the transponder and those present at various locations in the interrogator/receiver. Traces (A) through (K) illustrate the transmission of one phase shift, or the encoding of a logic "0". The transmission of a logic "1" is not illustrated because a logic "1" is transmitted only when no phase shift occurs over two bit periods, hence, the same repetitious waveforms would be illustrated for two whole bit periods in order to illustrate the transmission of a logic "1".
Traces (A) through (E) illustrate the transponder's operation and are in-phase with respect to one another. Traces (F) through (H) illustrate the operation of the interrogator/receiver. Although traces (F) through (H) are in-phase with respect to one another, they will most likely not be in-phase with respect to traces (A) through (E) because the different orientations of the transponder and receiver coils change the relative phases of the two groups of signals. Likewise, traces (I) through (K), which illustrate the operation of the phase detector 236, are in-phase with respect to one another but have a shifting phase with respect to traces (F) through (H).
Trace (A) is the 134 KHz carrier signal which appears on the "clock side" of the bridge rectifier 204 as measured at node 206. Trace (B) is the recovered clock signal output by the clock pulse recovery circuit 208. Trace (C) is the gate drive signal output from the double pulse lockout 222. When this signal is high, normally every other clock pulse in accordance with the modulation of the 67 KHz subcarrier, the FET 210 shorts out the "FET side" of the rectifier bridge as described above. However, as will be recalled, certain phase changes can result in the addition of an extra high pulse in the gate drive signal, which can undesirably short out the coil 202 for two 134 KHz cycles in a row. Trace (C) shows how this additional pulse 240 (shown by the dotted lines) would appear in the gate drive signal if it were not for its removal by the double pulse lockout 222.
Trace (D) is the voltage signal which appears across the transponder coil 202. The chopped pulses of the sinusoid are a result of the FET 210 being turned on by the gate drive signal. When the gate drive signal skips a regular pulse, as a result of the phase select switch 218 and the pulse lockout 222, the trace (D) stays high two pulses in a row. Trace (E) is the current through the transponder coil 202. The larger current peaks are a result of the coil 202 being shorted by the FET 210, which corresponds to the variations in the voltage signal of trace (D).
Trace (F) is the bit period in relation to the signals received by the receiver coils 32 and 34 from the transponder 30. Trace (G) is the analog output of the receiver circuit 232. Trace (H) is the output of the comparator 234 after it has "squared up" the receiver output. Note that due to the difference in orientation of the receiver/interrogator and the transponder 30, the traces representing the signals within the receiver/interrogator are displaced by a distance Delta-one with respect to the phase of the traces representing the signals within the transponder 30.
Likewise, trace (I), which is the transmitter output of the exciter 230, has the same frequency as the signal represented by trace (A), but would not normally be in phase with trace (A) because of the difference in the orientation of the system. For example, as shown in FIG. 7, traces (I) through (K) are shown to be displaced from traces (F) through (H) by a distance Delta-two, wherein Delta-two is larger than Delta-one. Trace (J) is the synchronous output of the exciter 230 which is used to trigger the phase detector 236. As will be noted, the rising edge of the trace (J) corresponds with the zero-crossing of the trace (I) and clocks trace (H) into the phase detector 236. The rising edge of trace (J) is free to move in time anywhere along the line denoting the low pulse of the trace (H) and no phase change will occur until a desired phase change is instigated. After the desired phase change, the rising edge of trace (J) would be free to move in time anywhere along the line denoting the high pulse of the trace (H) without changing phase until the next phase change.
This mobility in phase alignment is a distinct advantage of the present invention because it allows for variations in the phase relationship between the sync pulse and the comparator output without resulting in an undesired phase change. Although a phase change may occur in some situations, since the microprocessor 238 is designed to only look for phase changes at specific times, such a change would generally not result in a misreading of the transponder's identification code. In addition, even if the phase change impacted the proper reading of the transponder's identification code, the data rate and bandwidth efficiency of the system are such that sufficient readings could be taken by the system before the transponder had a chance to move out of range. Finally, trace (K), which is the output of the phase detector flip-flop, indicates the absolute phase of the incoming 67 KHz subcarrier signal. The microprocessor examines this phase signal and assigns a zero to the decoded data output whenever the phase changes in a bit period.
FIG. 8 illustrates a timing diagram for a typical bit sequence of a bit stream modulated in accordance with the above description, and in particular, to the description of FIG. 7. As shown the initial bit period is high, but the second bit period switches to low at the first phase change. Because the phase does not change at the start of the third bit period, the third bit period is high. A new phase change causes the fourth bit period to go low and a subsequent phase change causes the fifth bit period to stay low. 4 Hence, it can be seen that through the bit stream "1 0 1 0 0 1 1", a change in phase of the signal at the fall of the eighth cycle always results in a logic "0" while no change results in a logic "1".
With reference now to FIG. 9, the full-wave bridge rectifier 204 is shown in greater detail. The positive swings of the AC voltage input to the rectifier 204 from the coil 202 is clamped by the diodes 250 and 252 to Vcc. The P-channel FET 254 clamps the negative swings of one side of the coil 202 to the threshold voltage of the P-channel FET 254 (about -1.0 volts), while the parasitic transistor 256, which is formed by the inherent construction technique of the integrated circuit, clamps the other side of the coil 202 to -Vbe (about -0.6 volts) on its negative swings. In this manner, the AC coil voltage is full-wave rectified and the resulting DC voltage is applied to the integrated circuit as Vcc.
It should be noted that since the distance between the transponder and the transmitting coil is not fixed, wide variations in the induced AC coil voltage are likely to occur. However, the bridge circuit 204 can reduce the variance which would otherwise appear in Vcc with each change in the AC coil voltage. At large distances, transistor 256 merely acts as a diode to rectify the AC coil voltage, but as the transponder is moved closer to the transmitting coil and V would otherwise increase, transistor 256 turns on harder and draws substantial collector current, thereby reducing Vcc by shunting the current to ground. It should also be noted that it is an advantage of the preferred embodiment of the present invention that with respect to the transistor 256, the use of a parasitic transistor, or any transistor for that matter, as a Vcc shunt regulator allows the transponder to be placed right on top of the exciter coil without suffering malfunction or damage in the transponder's circuitry as a result of a large increase in operating power.
Although the present invention has been described in terms of specific embodiments, it is anticipated that alterations and modifications thereof will no doubt become apparent to those skilled in the art. It is therefore intended that the following claims be interpreted as covering all such alterations and modification as fall within the true spirit and scope of the invention.

I was about 4. I tried to mail my tomcat to my grandma. (Hey! She said she wanted to see him!) Lucky Mom saw, or the mailman would have had a big surprise!
I was four. My parents had been given some tootsie rolls. I asked for one and my mom said no. So, in the middle of the night I went sneaking into the kitchen, opened the drawer slooooowly, put my hand in the drawer and bam! On went the kitchen light! BUSTED!
Yes. :p I used to sneak out a lot and I got caught one time.

Monoclonal Antibody
Hundreds of monoclonal antibodies are being developed and are either being tested in clinical trials or are awaiting approval from the Food and Drug Administration. How do you make sense of what a monoclonal antibody is? How do you determine if it is worthwhile for you to participate in a clinical trial that tests monoclonal antibodies?
Finding information about Monoclonal Antibodies
What a monoclonal antibody drug? A drug developed as monoclonal antibody is made to target specific cells in the body called antigens. These drugs are being developed to specifically target the cancer cells. They are being used as a treatment for cancer and for immunological disorders.
Here are only a few names of the monoclonal antibodies you maybe familiar with:
- Abatacept (Orencia)
- Adalimumab (Humira)
- Bevacizumab (Avastin)
- Ibritumomab tiuxetan (Zevalin)
- Infliximab (Remicade)
- Rituximab (MabThera).
Most monoclonal antibodies are derived from cells that are cloned in a mouse.
What is Hot Right Now?
The first FDA approved monoclonal antibody was in 1986. The goal of a drug derived from a monoclonal antibody is to have a specific target. They are a relatively new classification of drugs, but the idea to target specific cells is novel and widely accepted. Since the start of the new century, the industry of testing and developing monoclonal antibodies has grown exponentially. Although the industry is growing, there is still concern that these are very new drugs that will undergo multiple clinical trial tests.
Read the Side Effects
you are prescribed an FDA approved monoclonal antibody, for example, Humira for
rheumatoid arthritis, make sure you read about the risks and side effects. Keep
in mind these are relatively new drugs. The idea of targeting the cells that
you don't want in your body sounds excellent, but they are still not considered
miracle drugs.
Talk to Your Doctor
Consult with your physician or healthcare professional before seeking treatment with monoclonal antibodies. Consider clinical trials that are testing these drugs. Refer to the government website below to learn more about clinical trials available that use monoclonal antibodies. Click on the resources below to learn about how to participate in a clinical trial.

Why a Clinical Trial? First of all it can be very scary being diagnosed with cancer. Your doctor may immediately want to talk to you about a clinical trial and you may feel as though this is your only...

text: Hello, Here is the deal. I bought a wii (it is version 3.4u) I have an SD card 2 g formatted(FAT). Can not do the chip got glue. On the root of it I have( apps folder, boot.dol, private, & wad folder). I have the homebrew channel already loaded. I have all sorts of zip files with all sorts of files. I have even got some of my emulators working. I am trying to get to the point of being able to download backup launcher/loader. Everyone seems to have the answer but none have worked. I have tired every wad manager out there (I either get titling error-1035 or ticket - 2011) I do not have the ios 249 so I can not go forward. I then tried to go the round about way and go ios 16 to ios 249 with a couple programs. I thought I found the key last night( which was downgrade to 3.2 and go from there but again to do this you need to use the wad manager( same errors) I have done the cios16 rev 7.prod.wad and cios 16 , rev 10, fix wads and all get errors. I can never get past this point. I have looked on you tube, instructables, various websites and people say it works but I do not know how. I hope is something simple. Please help ( I can get all files on sd card then on homebrew ( some wads manager just give blank screen when loaded) Most have 3 files in them(boot.dol, xml file, & mpg file). do they need all of these or really just the boot.dol file, and is this the reason for the blank screen. I really need help. If someone can walk me through the correct course. Either through this site, e-mail or phone call. I would be indebted. I thought that I was pretty savy with computers but this is kicking my but. Thanks again

Over the last few months, we've been working hard to deliver you an awesome Q1 2013 release (which you can read more about, here). Along the way, we figured today was time to drop a Service Pack for Q3 2012, which includes a bunch of new features and a boatload of fixes. In this blog post, I'll highlight a few of things we've added in this release. To download the Service Pack right away, head over to the downloads page of your account. This post won't cover everything new and improved, so to read more, be sure to check out the change logs:
The Kendo UI Q3 2012 service pack provides a number of updates, fixes, and enhancements to the version of Kendo UI we shipped in November of 2012. From a high-level perspective, we accomplished a great deal of work for this latest milestone:
Here are just a few of the cooler fixes and enhancements we've implemented in this service pack:
New! Check for changes in the DataSource
With this Service Pack, we added the ability to call hasChanges() on the Kendo DataSource, which returns true if the underlying data has changed since the last read.
var ds = new kendo.data.DataSource({
schema: {
model: { id: "id" }
data: [{ id: 1, name: "Burke" }]
output.innerText = ds.hasChanges() // Returns false
ds.get(1).set("name", "Brandon"); // Change some data
output.innerText = ds.hasChanges(); // Returns true
New! Support for canceling the requestStart event
Another addition we recently made to the DataSource is the ability to cancel the requestStart event of the DataSource by calling e.preventDefault() this can be useful in cases where you want to prevent a refresh on the DataSource under certain conditions, as illustrated in this completely contrived example:
var ds = new kendo.data.DataSource({
data: [{name: "Brandon"}, {name: "Burke"},
{name: "Derick"}, {name: "Todd"}],
requestStart: function(e) {
if (dontRead.checked) { // Don't refresh if checked
output.innerText = "Read Canceled";
e.preventDefault(); // Cancel the refresh
New! Editor Link dialog now supports localization
With the Service Pack, we've added three new additional properties to the Editor messages options literal that allow you to control the input labels on the link dialog. So, if I wanted to localize the labels in another language, say Urdu, I could add the following options to my editor initialization:
messages: {
linkWebAddress: "ویب ایڈریس",
linkText: "متن",
linkToolTip: "اوزاری ٹوٹکا"
Then, when a user clicks on the Link button, the dialog labels are now localized, as shown in the following image.
New! Additional widget configuration options for MVC Wrappers users.
We added a lot of new features in this quarter that will be of particular interest to our MVC Wrappers customers. These include support for deferring widget initialization scripts outside of the widget wrapper, the ability to specify aggregate member names on the grid, a configuration builder for setting column filter options on the grid, and series highlight configuration options on DataViz charts. Be sure to check out the Demos and you SP bits to try these features out.
New! Additional DataViz demos, features and enhancements
In addition to adding some additional demos to our recently-release Stock Chart widget, we've also added some new features to DataViz charts and gauges, including series highlight configuration options, the addition of selectStart, select and selectEnd events on charts and additional data attributes for radial and linear gauges.
New! PopOver open event handler provides target element data.
In addition to a number of fixes we added to Kendo UI Mobile, we've added target element information to the PopOver open event, which returns the DOM element that the user clicked on to open the PopOver widget:
popOver = $('#popOver').data("kendoMobilePopOver");
popOver.bind("open", function(e) {
console.log("Opened by: " + e.target[0]);
There's a lot more great stuff in the Service Pack, so head on over to the the downloads page in your account and get the bits now!
While you digest everything new in the Service Pack, we'll keep on working on the Q1 2013 release, which you'll get to see more of as we approach the next two milestones:
We've already talked about a lot of what's coming in the Q1 release, but we've also got a few surprises up our sleeves. Today, I'm happy to share one of these with you….
As many of you know, TypeScript is a compile-to-js maintained by Microsoft. The language is still very-much in an Alpha state, but we've gotten so much demand from our customers, that we decided to start offering support (in the form of TypeScript definition files for Kendo UI ) sooner, rather than later. If you're a TypeScript fan-boy or -girl, keep an eye out for those in the Beta timeframe.
These are just a few of the updates, fixes, and enhancements that you'll find in the service pack for the Kendo UI Q3 2012 release. Many of the bugs and feature requests we implemented came directly from you; our customers. We spend a great deal of time tracking your feedback on our forums, our UserVoice site, Stack Overflow, Twitter (@KendoUI) and elsewhere online. As always, we welcome all feedback. Please continue to submit your requests. We'll continue to make Kendo UI more awesome.

The New England Fisheries Management Council (NEFMC) met January 24, to hammer out what will be the foundation of a sector planthat is allocation.
The volume of fish allowed to be taken is key to sustainability, in the eyes of the National Marine Fisheries Service (NMFS). The NEFMC, aware that its motion on sectors and the 2009 implementation date is an eleventh-hour one, was moving forward with it after a vote of support at the January 17 meeting. The option, waiting another year, as councilmen and fishermen generally agree, could see many more ground fishermen driven out of business and 400 hundred years of New England fishing changed forever.
In addition to the pressure from the National Marine Fisheries Service for the council to continue with the lethal days at sea (DAS) system, the service is pressing to extend the implementation date out to 2010. Fishermen know that between the number of days at sea dropping and a change in the policy dragged out to 2010, many of them will not be around to see the outcome.
In a two-page letter dated 12/7/07, addressed to John Pappalardo, NMFS Regional Director, Pat Kurkel wrote that she did not believe the council could have a sector plan within Amendment 16 for NMFS to implement by the May 1, 2009 deadline. She went on to say NMFS did not have the staff, science or money to for developing a sector plan for 2009. Pulling NMFS support for the councils efforts got the councils attention.

Fiberglass is forever. It never dies, says Keith Otis, whos set firmly into an office chair a floor above where FIRST TEAM dominates one bay of his shop. The time clock punctuates Otis words with an intermittent ka-dunk as he continues, Those Liberty Boats the Navy was doingthose 34smost any harbors got a few still kicking around.
First came the Webber Coves Jughead (Cy) Cousens trained REPCO (in fiberglass construction) and Glen Holland finished off both WEBBER COVES and REPCOS. Early on, there was Dave McGraw, Billings... Bruno & Stillman was a Granddaddy of fiberglass... Otis head is cocked and hes got his eyes fixed, as if hes drawing a bead on a prowling target as he pulls things from memory.

When Blue Hill Marine first came out with their design, there was a little skepticism about the under the floor engine placementsometimes a guy would almost unintentionally walk around it. BHM did a 25', then a 31', then a 39'. They moved Blue Hill to Flye Point, becoming Flye Point Marine, then the business changed handsand then the company was known as Atlantic Boat.

Guleek i8 hands on review, excellent windows desktop with battery
The Guleek i8 is a mini desktop computer with a built in battery. This makes it one of the most unique desktops around. It is as small as Zotac mini PCs but has a 3000 mAh battery inside too which allows you to move it from one place to another without shutting it down.
The Guleek i8 is a compact computer with windows 8.1 operating system and is powered by Intel bay trail processor.
Guleek i8 video review
As you can see, this is basically a mini laptop without a display. It features 1.8 GHz Intel Atom Z3735F quad-core processor, 2GB of RAM, 16GB of storage, a microSD card slot, and a fanless design.
On the ports front you get 2x USB 2.0 ports, a micro USB port (for charging), a micro HDMI port, a headset jack, 802.11b/g/n WiFi and Bluetooth 4.0. It measures 5.9″ x 3.2″ x 0.4″ and weighs about 8.5 ounces.
Here is what we did not like about it:
- Doesn't have a network port;
- The power socket is right next to the USB sockets, should be on the back;
- You can find tablets for the same price with bigger batteries, a screen, and more storage.
This would be interesting paired with one of the old Motorola Lapdocks from the Atrix/Bionic era. The lapdock itself is powered and would provide nearly everything else that's missing: Display, keyboard, trackpad, audio (possibly), and maybe some extra USB ports. Roll your own networking? Just Velcro the thing to the back of the lid and route the cables into the dock ports like with any other stick PC.
Verdict – It's really pointless when consumers can spend less and have a fully portable system with dual functionality. This mini PC would only work if it was on par with prices to the ARM devices. If you need a dual display option you can buy a Asus Vivo that runs Intel 4th Gen. It supports THREE displays connected at once, runs Linux and Windows and is almost the same price as this mini PC. And has USB 3, Ethernet "yada yada". I just don't see the market appeal if its priced the same as a tablet.

From 2008 to June 2014, Chinese outbound investment in commercial property grew more than 200-fold and totaled about US$33.7 billion during the period, according to the white paper titled "China's Outbound Boom: The Rise of Chinese Investment in Global Real Estate."
"We see a variety of fundamental forces driving China's outbound investment trends today," said Mark Suchy, director of investment and capital markets, East China, Cushman & Wakefield. "Domestic restrictions and cooling market conditions in the Chinese real estate sector are pushing many investors to diversify to developed countries, where signs of economic recovery and the prospect of asset appreciation promise more attractive returns."
"Positive Chinese policy reform, the strengthening of the yuan and the desire of Chinese firms to internationalize are further fueling these capital outflows," he added.
A variety of investors — including large private developers, state-owned banks and insurers, sovereign wealth funds and high-net-worth individuals — are tapping into foreign property markets. While state-owned enterprises and private firms each contributed around 50 percent of the total value of outbound real estate investment during the period, private enterprises and individual investors accounted for a larger share of the number of deals, the white paper said.
Among all, office buildings are by far the preferred property type during the period, accounting for over 48 percent of total aggregate investment to date. Office investments experienced a spike in 2013, reaching US$8.4 billion — greater than the sum total for all other asset classes of US$7.4 billion that year.
"Chinese mainland investors prefer developed and mature markets in Asia, North America and Europe," said Ted Li, national director of capital markets, China, Cushman & Wakefield. "The US is the top destination, followed by the UK, China's Hong Kong, Singapore, Australia, Malaysia, Japan and Brazil."
China's investments in US property are concentrated in so-called "gateway cities" in the eastern and western coastal areas as well as the Great Lakes region. However, investors are increasingly tending to diversify their asset choices and spread their investments across the country.
The UK is the first choice for Chinese real estate investors in Europe, with London alone taking 62.7 percent of the European total. Southeast Asia is a favorite location as well, due to its proximity to China and the strong presence of ethnic Chinese communities. In Singapore, Chinese investors prefer to invest in offices, whereas in Malaysia, land development is the preferred vehicle.
"New York City, Los Angeles, San Francisco, London and Sydney will remain top investment destinations for Chinese outbound investment in the West, while cities like Seattle,Dallas and Melbourne will become more relevant as Chinese capital increasingly taps these 'second-tier' destinations," Suchy added.

The modification is nicely presented. I have some basic doubts on this.
- Which companies can donate to political Parties?
- How much they can contribute (Is there any monetory limit) ?
- Do we have to pass a board resolution for donations to political parties?
- Which office or director will be held repsonsible?
- Is there any creteria fixed for political parties? Which parties can be given donations? Can we donate to any political party or only National parties?

@Rahul Rai
1. Any Company other than a Government Company which is in existence for 3 or more financial years may contribute
2. There is a upper limit of 7.5%. of Average Net profits of 3 preceding FYS. No Specific permissible Amount is prescribed.
3. Yes passing a board resolution is necessary and is sufficient compliance of the Act
4. The Officer in default is yet to be prescribed by the act. However, we can safely presume that board of directors as officers in default.
5. No Criteria as such has been prescribed till now. However, there are 2 deemed clauses which spellout the circumstances in which the amounts paid shall be considered as Political contributions.
