This is a continuation of application Ser. No. 905,433, filed Sept. 10, 1986, abandoned.
1. Technical Field
The present invention relates to computer controlled material handling systems as used in factory automation. More particularly, it relates monitoring and handling the many input and output signals distributed throughout a system comprised of a variety of material handling devices and plurality of workstations which signals are indicative of workstation status.
2. Background Art
It is known to use direct computer I/O to provide a solution to the problem of monitoring a great plurality of I/O signals generated in a highly mechanized manufacturing operataion. The disadvantage to such a system is that the control computer must have great I/O capability and must poll all inputs and outputs. Additionally, much cabling is needed to make the connections.
U.S. Pat. No. 4,306,292 describes the segmented asynchronous operation of a automated assembly line including a control computer in communication with a plurality of worker computers which are not automatically polled as in the present invention.
U.S. Pat. No. 4,100,533 discloses a multi-point polling technique which relieves the control computer of some polling overhead, but does require that it transmit an address list for polling periodically.
U.S. Pat. Nos. 3,747,074 and 3,775,751 relate to methods of apparatus for baud rate detection involving special circuitry to process data transmission and determine the baud rate by timing the transmission times.
In highly automated manufacturing installations including many workstations at which the same or differing operations are performed, remotely guided vehicles are used to transport work in progress to the workstations. The path of the vehicle, work in progress route, changes as a result of several factors, not the least of which is the condition or status of a workstation. Such conditions include whether the workstation is operative and available to receive and process work. It is desirable to optimize vehicle path length to transport work to workstations so that non-productive time is minimized and system throughput is increased.
The present invention provides automatic polling of input and output signals distributed throughout an automated material handling system by automatically polling and storing workstation status data from a plurality of Remote Station Controllers RSCs, in communication with the workstations. The data is transmitted to a Control Interface Unit CIU which provides the data to the control computer on demand. The CIU resumes polling while the control computer processes the data. Since all polling and buffering is done by the CIU; the control computer is relieved of time consuming polling and data request operations leading to more efficient throughput and minimized down time of the factory installation. Further, the manner in which workstation status data is transferred to the control computer enhances the control of vehicle movement among the workstations.
For better understanding of the present invention together with other and further advantages and features thereof, reference is made to following description taken into connection with the accompanying drawing in which:
FIG. 1 is a schematic block diagram of a control system for an automated manufacturing process.
FIG. 2 is a block diagram of CIU 20.
FIG. 3 is a block diagram of a serial multiplex card 104 in FIG. 2.
FIG. 4 is a block diagram of one RSC 30 FIG. 1.
FIG. 5a-d is a flow diagram of the CIU Main Program.
FIG. 6a-e is a flow diagram of the CIU Control Computer Service Program.
FIG. 7a-e is a flow diagram of the RSC Main Program.
FIG. 8a-c is a flow diagram of the RSC CIU Service Program.
In a highly automated multi-step manufacturing/ assembly process, many material handling devices such as vertical storage systems, conveyor systems, transport, guided vehicles and the like are involved. Such a process includes controlling material flow through complex processes at many stations. A computer for controlling such a system must continuously monitor and control many I/O signals for successful process operation with minimum down time and maximum throughput.
Monitoring of the various I/O signals is typically performed via switches, photocells, and controls by using relays or LEDS. Information transmitted via these signals triggers process control decisions and material move transactions. The reliability of these information signals is therefore of critical importance.
Such automated manufacturing or assembly installations cover many square feet involving large distances between individual workstations. It is desirable that the control system be extremely reliable, easily maintainable and efficient.
FIG. 1 shows control computer 2 connected to the universal multiplexer system UMS 10 of the present invention. UMS 10 is a microprocessor controlled modular system for automatically determining the status of input devices and reporting that information, on demand, to control computer 2. Operator communication to control computer 2 occurs via system components, terminal 4 and printer 6. Control computer 2 is connected directly to the Control Interface Unit CIU 20 of the present invention which in turn communicates with up to 32 Remote Station Controllers RSCs illustrated at 30, 32 and 34.
Each RSC 30, 32 and 34 can support up to 32 input and 16 output lines where the communication is to a plurality of various workstations, represented at 40, 42, and 44, in the manufacturing installation. Control computer 2 is also in communication with an automated material handling system control 50, which also interacts with workstations 40, 42 and 44.
Refer now to FIG. 2, a block diagram of CIU 20. CIU 20 hardware includes a processor card, a mother board, two serial multiplex cards 104, and a power supply. A processor 110 is provided for controlling UMS 10 in FIG. 1. Processor 110 is driven by system clock 112 to process and store data in memory 114, which may be a random access device. Programs for driving CIU 20 are stored in memory device 116.
A programmable peripheral interface 118 is used to provide the data link to control computer 2, FIG. 1, and consists of 16 Digital Input (DI) lines and 16 Digital Output (DO) and data synchronization signals.
Data and program information are transferred via address bus 120, control bus 122 and data bus 124. Address bus 120 provides address information and control bus 122 provides clock signals, read/write signals and the like. Data bus 124 is a bidirectional bus for program and data information. Processor 110 is connected to two serial multiplex cards 104 by address, control and data bus signals on buses 120, 122 and 124, respectively. These signals are buffered by an address bus interface 130, control bus interface 132 and data bus interface 134, respectively. The two serial multiplex cards 104 are essentially the same so only one will be described in connection with FIG. 3. The first serial multiplex card 104 deals with the first 16 of the 32 possible RSCs while the second serial multiplex card cooperates with the other 16 of the 32 possible RSCs. Refer now to FIG. 3, which shows a block diagram of one of the serial multiplex cards 104 included in CIU 20. Address, control and data buses 120', 122'and 124', respectively from bus interface devices 130, 132 and 134 (FIG. 2) are input to address bus interface 140, control bus interface 142 and data bus interface 144. Address bus 148 connects address bus interface 140 to address and control logic 150. Similarly, control bus 154 connects control bus interface 142 and address and control logic 150.
Address and control logic 150 is provided for interpreting address and control information in order to select either the serial channel latch 158, switch status interface 160 or serial data converter 164. When serial channel latch 158 is selected, it accepts a new channel address from the data bus for connecting serial data converter 164 to one of the RSCs by means of serial multiplex circuitry 170.
Serial multiplex circuitry 170 connects transmit and receive signals 172 and 174 from serial data converter 164 to one of the 16 RSCs served by this serial multiplex card 104. In this preferred embodiment 16 current loop interfaces CLIs 176 are provided to convert serial data so that it can be reliably transferred between the RSCs and CIU 20 over the large distances involved in a factory environment.
A switch status interface 160 enables the status of the rate switches 182 to be read by processor 110. Rate switches 182 determine the serial communication rate to be gated by rate select logic 180 to the serial data converter 164. A clock crystal 186 and baud rate generator 188 are used to generate communication rates ranging from 9600 baud to 75 baud. Serial data converter 164 utilizes the selected serial clock signal on line 190 to transmit and receive serial data to and from the selected RSC. Parallel data from the processor is converted by serial data converter 164 to serial data and transmitted to the selected RSC. When the RSC's response is received by serial data converter 164 the data is converted to parallel and transferred back to processor 110.
Refer now to FIG. 4, which is a block diagram of one of the 32 RSCs in the system. Each RSC includes a power supply (not shown). Processor 200 may be an 8 bit single chip processor and is driven by a crystal 204 for processing and storing data in memory internal to it. Software commands for driving the RSC are stored in another memory internal to processor 200.
Device 206, which may be an optical coupler receiver for receiving a signal from CIU 20, provides an input to processor 200 while processor 200 provides an output to output device 208, which may be an optical coupler transmitter. Serial to parallel and parallel to serial conversion may be implemented internal to processor 200 as is well understood by those skilled in the art.
Crystal 210 is provided for driving a baud rate generator 212 for generating communication rates to processor 200. The desired communication rate is jumper selectable, and the resulting rate is connected to the clock and timer inputs of processor 200 on lines 214 and 216 respectively. The signal on line 216 is used to measure the duration of the jumper selectable serial clock signal to enable processor 200 to determine the selected baud rate. Once the baud rate is determined, the communication timeout values may be calculated as below described for the desired communications rate. The technique just described of determining baud rate eliminates the need for three components conventionally used for this purpose. The technique used on and described in connection with CIU multiplexer cards 104, FIG. 3, is exemplary of conventional methods of determining baud rate, and requires three components--a rate select device 180, rate switches 182, and a switch status interface unit 160.
Data input to processor 200 is on bus 220 and is gated thereon from one of six tristate buffers 222, 224, 226, 228, 230 and 232. Processor 200 selects date through input select device 234. The first four tristate buffers 222, 224, 226 and 228 are used to read the status of external inputs that may typically be switches, relay contacts, TTL logic and the like. These four groups of eight bits are busses 223, 225, 227 and 229 respectively, are software partitioned into four addresses of eight bits each. The fifth tristate buffer 230 is used for auxiliary inputs on bus 231 as below described. The sixth tristate buffer 232 receives input from output latch 236 on bus 238 for providing a method of self test on the DI/DO buses.
Data output from data processor 200 is placed onto data out bus 240 and directed to one of four output latches 236, 244, 246 or 248. One of these latches is selected by processor 200 using output select device 250.
Latch 244 is connected to tristate buffer 230 via external connections for encoding a unique RSC box address and latch 244 drives a "polling" light provided to display polling status described later. Latches 246 and 248 are used to control external output devices such as indicators or the like in the manufacturing work area through drivers 254 and 256.
The just described configuration supports four addresses with 8 inputs and 4 outputs each. The ability to perform self testing and address verification for insuring data integrity is an advantage of the present invention. This configuration further assures that outputs are not affected by erroneous commands from CIU 20 should a malfunction occur therein.
Refer now to FIGS. 5 and 6 for a better understanding of the software control for CIU 20. This software comprises 2 main sections; the main program CIUMP and the control computer service program CIUSP. CIUMP begins when the CIU 20 is powered up and runs continually, polling RSCs except when interrupted by control computer 2. When an interrupt occurs CIUSP services the interrupt and returns control of CIU 20 back to CIUMP.
Refer to FIG. 5. The CIU Main Program begins when the CIU is powered up by initializing the input and output devices at blocks 301-303 and then reading the communication Rate Switch status on each of the Serial Multiplex Cards at 304. The switch status settings are compared at step 305, and if they are different the program stops at terminal 306. If the communication rates are the same, processing continues by calculating the time out value for the selected communication rate and storing the calculated value at step 307. At block 308 data storage locations for the input and output data are initialized to the inactive state and any interrupt from control computer 2 is enabled at step 309 should an interrupt occur.
To begin polling the RSCs, RSC channel address is set to 00 at block 310. A Read Command is constructed at block 311 as shown in Table 1 for this RSC.
TABLE 1__________________________________________________________________________READ COMMAND[STX] [R] [ADDH] [ADDL] [NULL] [NULL] [NULL] [NULL] [CKSUM] [ETX]__________________________________________________________________________STX Start of transmissionR "Read" command.ADDH High bite of the RSC box address.ADDL Low bite of the RSC box address.NULL Four NULL characters are used to make the "Read" command the same length as the "Write" command.CKSUM Binary sum of the bits of all characters with the most significant bit forced high.ETX End of transmission.__________________________________________________________________________
All command element characters are transmitted in seven bit ASCII except for the CKSUM which has its most significant bit high making the CKSUM character unique from all the others. Once the Read command is constructed, the control computer interrupt is disabled at block 312 and the command is transmitted to the RSC at step 313. If the RSC does not respond at decision block 314, the CIU assumes that no RSC exists on this channel address and prepares for the next RSC at steps 337 and 338.
If the RSC did respond to the Read command by transmitting a NAK character at block 315 up to two more retransmit attempts are made as indicated at step 316. If there is still no ACK response, an error flag is set for this RSC at block 317 and the program prepares for the next RSC at blocks 337 and 338. If there is an ACK response from the RSC, the CIU prepares to receive the status response from the RSC at 318. If the RSC response is not received timely as tested at block 319, the program prepares for the next RSC at blocks 337 and 338. If the RSC message is found not valid at test 320, i.e. the starting character, ending character and check sum do not match, retransmission of the RSC status message is twice requested by sending a NAK character to the RSC as shown at blocks 328 and 329. If by the third try the message is still not successfully received, control branches to setup for the next RSC at blocks 337 and 338. If the RSC message is valid, an ACK character is transmitted at block 321 to confirm receipt of the response.
The format of the RSC status message received in blocks 318-321 is shown in Table 2.
TABLE 2__________________________________________________________________________RSC STATUS MESSAGE[STX] [STATUS] [ADDH] [ADDL] [SW0H] [SW0L] [SW1H] [SW1L] [SW2H][SW2L] [SW3H] [SW3L] [CKSUM] [ETX]__________________________________________________________________________STX Start of transmission.STATUS Status byte to indicate errors or status normal.ADDH High bite of the RSC box address.ADDL Low bite of the RSC box address.SW0H High byte of the input status for RSC subaddress 0.SW0L Low byte of the input status for RSC subaddress 0.SW1H High byte of the input status for RSC subaddress 1.SW1L Low byte of the input status for RSC subaddress 1.SW2H High byte of the input status for RSC subaddress 2.SW2L Low byte of the input status for RSC subaddress 2.SW3H High byte of the input status for RSC subaddress 3.SW3L Low byte of the input status for RSC subaddress 3.CKSUM Binary sum of the bits of all characters with the most significant bit forced high.ETX End of transmission.__________________________________________________________________________
Once the RSC status response is successfully received, the CIU processes the message at block 322 by checking the ADDH and ADDL to insure that the RSC address matches the selected channel and checking at step 323 the status byte for any system self test errors. If an error exists, the Read error bit is set at step 324 for this RSC. Next SWOH and SWOL through SW3H and SW3L are converted from ASCII to binary and stored at process block 325. If the new status is different than the information previously stored as indicated by compare step 326, a status change flag is set for this RSC subaddress at block 327.
To complete polling of this RSC, a Write command is constructed at step 330 to update the status of the RSC outputs. The format of the Write command is as shown in Table 3.
TABLE 3__________________________________________________________________________WRITE COMMAND[STX] [W] [ADDH] [ADDL] [OUT0] [OUT1] [OUT2] [OUT3] [CKSUM] [ETX]__________________________________________________________________________STX Start of transmission.W Write commandADDH High bite of the RSC box address.ADDL Low bite of the RSC box address.OUT0 Output status information for RSC subaddress 0.OUT1 Output status information for RSC subaddress 1.OUT2 Output status information for RSC subaddress 2.OUT3 Output status information for RSC subaddress 3.CKSUM Binary sum of the bits of all characters with the most significant bit forced high.ETX End of transmission.__________________________________________________________________________
Output status data for each RSC is stored in a RAM area in the CIU during interrupt servicing of the control computer as will be explained more fully below in connection with FIG. 6. After the Write command is transmitted at step 331, the program checks for a RSC response at block 332. If no response is found, the program sets a Write error flag at block 335 for this RSC and prepares for the next RSC at block 338. If a response is received and it is not an ACK character as shown by compare step 333, the CIU tries up to twice more to transmit at block 335. If that fails a Write error flag is set at block 334 and the program prepares as before for the next RSC. If the Write command is acknowledged by an ACK character at block 333, polling of this RSC is complete and the program prepares for the next RSC at block 338. The CIUMP continuously polls all of the RSC channels until an interrupt is received from the Controlling computer.
When an interrupt is received from the control computer, execution of CIUMP stops and the CIU Control Computer Service Program CIUSP begins (See FIG. 6). Once the CIUSP satisfies the control computer request, control of the CIU is returned to CIUMP and polling of the RSCs resumes.
As shown in FIG. 6, CIUSP begins processing a control computer interrupt at block 339 by reading at block 340 the command of the DI bus and determining the type of command by checking the command character received from the control computer in the tests indicated at blocks 341, 342, 343, 344, 345, 348 and 349. The commands are listed in Table 4 with a brief description of their function.
TABLE 4______________________________________CONTROL COMPUTER COMMANDSCOM-MAND FLOWCHAR- CHARTACTER DESCRIPTION BLOCK NO.______________________________________A Request all input data without 341 data with error status.B Request for all input data that has 342 changed without data with error status since the last A of B request.C Request input data for a single address 343D Request output and error status for a 344 single address.E Request input data with error status. 345F Set an output bit high on a single 348 address.G Set an output bit low on a single 349 address.______________________________________
A or B commands, for All Input Data 341 or Changed Input Data 342, are received in a format wherein the command portion consists of a 7 bit ASCII code for the character A or B with the most significant bit, control computer bit 15 or CIU bit 7, used as a parity check bit. The least significant byte is not used for these two commands.
A type A or B command, causes a branch to a single routine. In addition, a Changed Data Flag is set at 346 for a type B command. This routine, FIG. 6C, begins by selecting an RSC address as shown at block 359 and reads the input data at block 360. The address selection technique referenced at block 359 determines the order that RSC status information is transmitted to control computer 2. This order is predetermined to group related vehicle moves in an area or flow to minimize transactions applicable to material handling systems containing such a vehicle. Forward and reversed Status Sequence Tables are provided to enable two differing sequences to be used, so that the vehicle can service moves while advancing from the process starting point to the ending point and service moves from the next type A or B command while it advances from the ending point back to the process starting point. If the Changed Data Flag is found at test set 361, an additional check is made on the changed data bit for the RSC address at block 367. If the data has not changed, CIUSP continues to the next RSC address.
If this is a type A command, or B command where the data is changed, the CIUSP checks the status for this address at block 362. If the error bit is set, this data is not transmitted to the control computer. An error code is sent at the end of the routine, at block 368, to inform the control computer that an RSC has an error.
If the status is normal, the routine proceeds to check, at test 363, the most significant input bit to determine if an RSC exists at this address and if this address is active. If so, the input data is transmitted to the control computer at block 364.
The routine then advances to the next selected RSC address in the Status Sequence Table at block 365. This process is repeated until all RSC addresses have been processed as indicated by test 366.
Once processing of the last RSC is completed, CIUSP transmits an end of data word at block 355, with a normal or error status code as appropriate, and returns to the CIUMP at block 351. Table 5 contains status code values.
TABLE 5______________________________________STATUS CODES______________________________________FF Normal end.00 Parity error.01 RSC self-test error.02 Invalid control computer command.03 CIU time out.04 Invalid RSC address.______________________________________
Returning to test blocks 343 and 344 FIG. 6a, command types C or D, for Single Address Input Data or Single Address Output Data, are received in the following data format. The command portion consists of a 7 bit ASCII code for the character C or D with the most significant bit, control computer bit 15 or CIU bit 7 used as a parity check bit. The least significant byte contains the specific RSC address for the requested data with the most significant bit used as a parity check bit.
To service either a type C or D command, the program branches to a single routine with an output data flag being set at block 347 for a type D command. This routine, shown in FIG. 6D, reads the desired RSC address at block 369 from the least significant byte transmitted by the control computer with the command character. CIUSP sets an index pointer at block 370 to the desired RSC address and checks the output data flag at test 371 to determine if input or output data is requested.
If the flag is not set, input data is read from RAM at block 372 and transmitted at step 373 to the control computer. If the output data flag is set, output data is read at step 374 and transmitted to the control computer at step 373.
To complete C or D command service, an end of data response is transmitted to the control computer at step 355 as above described and CIUSP returns control to the CIUMP at terminal 351.
E commands for Error Data, test block 345, are received in the same data format as A and B commands. The command portion consists of a 7 bit ASCII code for the character E with the most significant bit, control computer bit 15 or CIU bit 7, used as a parity check bit. The least significant byte is not used for this command.
To service an E command, the program branches to an error service routine block 375, FIG. 6E, that begins at RSC address 00 and reads the status at block 376. The routine next checks status for this address at block 377. If the error bit is set, input data for this address is read from RAM at block 378 and transmitted to the control computer at block 379. If the error bit is found not set at test 377 or input data transmission is complete, the routine increments to the next address at block 380 and repeats the process until all the addresses as indicated at test 381 have been checked.
To complete E command service, an end of data response is transmitted to the control computer at block 355 and CIUSP returns control to the CIUMP at terminal 351.
F or G commands, as found at blocks 348 and 349, to Set Single Address Output Bit High or Set Single Address Output Bit Low, are received in the following data format. The command portion consists of a 7 bit ASCII code for the character F or G with the most significant bit control computer, bit 15 or CIU bit 7, used as a parity check bit. The least significant byte contains the specific RSC address for the requested output with the most significant bit used as a parity check bit.
To service an F command, the CIUSP reads at block 352, FIG. 6B, the desired address from the least significant byte of the first word transmitted from the control computer with the command. The bit desired to be set high is read at block 353 from the next word transmitted from the control computer. That bit is set high in memory at block 354.
Command F service is completed with transmission of an end of data response to the control computer at block 355, CIUSP returns control to the CIUMP as before at terminal 351.
To service a G command, CIUSP reads the desired address at block 356, FIG. 6B, from the least significant byte of the first word transmitted with the command character. The routine then reads at block 357 the bit desired to be set low from the next word transmitted from the control computer and sets that bit low at step 358.
To complete command G service, an end of data response is transmitted to the control computer at block 355 and control is returned to the CIUMP as heretofore described at steps 355 and 351.
Software associated with RSC processor 200 in FIG. 2 will be described in conjunction with the flow charts set out in FIGS. 7 and 8. The software which drives each RSC comprises two main sections; the main program RSCMP and the RSC CIU Service Program RSCSP. RSCMP begins when the RSC is powered up and runs continually, reading the status of the inputs to that RSC excepts when interrupted by CIU 20, FIG. 1. When an interrupt occurs, RSCSP services the interrupt and returns RSC control to RSCMP.
Refer to FIG. 7A to better understand the RSCMP which begins when the RSC is powered up by initializing the inputs and outputs at blocks 401 and 402 and initializing status locations and setting subaddress to 0 at block 403. The program then determines the jumper selected baud rate set in hardware by initializing the timer in processor 200 which receives input on line 216, FIG. 4, at block 404 and reading at block 405 the timer value measuring elapsed time until a change in the value of a register is detected at test 406. At block 407 the new timer value is subtracted from the initial value and the difference is stored at step 408.
The difference value is known to be proportional to the baud rate setting. A set of values corresponding to baud rate resulting from calculations based on this proportionality is resident in processor memory. Thus, a series of comparisons of the elapsed time value and precalculated values at blocks 409, 410, 411, 412, 413, 414 and 415, FIG. 7B, are performed to determine the correct baud rate. Once determined, a serial time out value corresponding to 75 baud is divided by 2 at steps 416, 417, 418, 419, 420, 421 and 422 until a serial time out value corresponding to the correct baud rate is reached. The resulting value is stored at step 423 for use by RSCSP.
Previous read counters are cleared at step 424, FIG. 7C, and any CIU interrupt occurring is enabled at step 425.
RSCMP then conducts an I/O bus test by using the self test hardware described in connection with FIG. 4. The program selects the I/O bus test at step 426 so that a data word can be written out and read back on the input bus. The following hex data words may be in bus test #1 at block 427: 80, C0, E0, F0, F8, FC, FE, FF. If errors are found at test 428 an error status is set at step 431 and the bus test is stopped. If no errors are found, the following hex data words are used in bus test #2 at block 429: 7F, 3F,1F, 0F, 07, 03, 01, 00. If errors are found at test 430, an error status is set as before. If no errors occur, the program continues by decrementing the polling light counter at block 432 and checking if the count equals zero at test 433. If the count has reached zero the program turns off the polling light at step 434 indicating that the CIU is no longer communicating with the RSC. The polling light counter is initialized in the RSCSP routine, explained more fully in connection with FIG. 8, that services the CIU interrupts.
The next portion of RSCMP reads input status and provides a software debounce to avoid incorrect data reads due to possible switch bounce or electrical noise problems. This is accomplished by checking 8 bits at a time for changes from the previous input status. This method works well in a factory floor environment where inputs change at a relatively slow rate, typical of movement in a material handling system. The 8 bit input status reads go through three stages to eventually be transmitted to CIU 20. The three stages are called the New Input Status, Previous Input Status, and finally Valid Input Status. New Input Status is the current read of the inputs. Previous Input Status is the previously read input data stored in RAM with a corresponding Previous Read Count to indicate the number of times the New Input Status has been the same as the Previous Input Status. Once the Previous Read Count has reached 0, the Previous Read Count is reinitialized and the New Input status is stored in the Valid Input Status location for possible transmission to the CIU.
This process of input status is shown in FIG. 7D at blocks 435-443. New Input Status is read at test 435 from one of the four RSC subaddresses and compared to the Valid Input Status at block 436. If the status is the same, the Previous Read Count is reinitialized at 442 and the program increments to the next subaddress at step 444. If status is not the same, the new Input Status is compared to the Previous Input Status at step 437. If they are not the same, the New Input Status replaces the Previous Input Status at block 441 and Previous Read Counter is reinitialized at step 442.
If the New and Previous Input Status are the same and the Previous Read Counter is greater than zero at block 438, the Previous Read Counter is decremented at block 443 and the program increments to the next subaddress at step 444. If the Previous Read Count is equal to zero at block 438, the New Input Status (same as the Previous Input Status) replaces the Valid Input Status at block 439, and clears the Previous Input Status and the Previous Read Counter at block 440.
The RSCMP then increments to the next subaddress as before at block 444 and checks if all four subaddresses have been read at test block 445. If all subaddresses have been read, the subaddress is set to 0 at block 446. Else; the program repeats the bus test and input status reads for the next subaddress until all subaddresses have been read. The program repeats this process continuously until an interrupt is received from the CIU.
When an interrupt is received from the CIU, execution of RSCMP stops and RSCSP begins. Once RSCSP satisfies the CIU request, control of the RSC is returned to the RSCMP and polling of the inputs resumes. RSCSP will be better understood having reference to FIG. 8.
A request sent from the CIU to an RSC causes RSCMP to be interrupted at terminal 447, FIG. 8A. Execution of RSCSP begins by receiving the CIU request at block 448. The CIU request is either a Read command, Table 1 or a Write command, Table 3. If the complete CIU request is not received timely as indicated at block 449, or the request is not valid as determined at 450 i.e., the starting character, ending character and check sum do not match, the program requests a retransmission of the CIU request by sending a NAK character to the CIU, block 455 and returns control of the RSC to RSCMP at terminal 456. If the CIU request is valid, the program transmits an ACK character to the CIU at block 451 to confirm receipt of request. The RSCSP then at block 452 turns on the RSC polling light and initializes polling light counter at block 453. This counter is decremented by RSCMP as above described.
RSCSP then determines if the CIU request is a Read or Write command by checking at block 454. If the CIU request is a Read command RSCSP constructs a RSC status message at block 457, FIG. 8B. Refer back to Table 2. To determine the status character, at test block 458, a comparison is made between the RSC address on the Auxiliary Inputs and the address encoded in the CIU request. If they do not match an error bit is set at block 459. RSCSP then checks if any RSC self test errors occurred at step 460 and, if so, sets a self test error bit at block 461. The resulting status character is loaded at step 462 into the RSC status message.
Next, Valid Input Status values are included at step 463 into the message. The RSC status message is transmitted at block 464 to the CIU. If no CIU response is detected at test 465 or if the RSC receives an ACK character from the CIU, test 466, the program returns control of the RSC to RSCMP at terminal 468.
If the CIU did respond to the RSC status message by transmitting a NAK character, then the program retransmits up to two more times at block 467 before returning control of the RSC to the RSCMP.
If the CIU request is found to be a Write command at test 454, the program compares the RSC address on the Auxiliary Inputs to the address encoded in the CIU request at step 469, FIG. 8C. If there is no match, an address wrong character is transmitted to the CIU at block 472, indicating that an error has occurred and the CIU Write request was rejected.
If the addresses do match, output data in the Write command received from the CIU is gated to the output latches 236, 244, 246 and 248 at step 470, in the RSC (FIG. 4). An RS character is transmitted at step 471 to the CIU to acknowledge that the Write command has been completed and control of the RSC is returned to the RSCMP at terminals 473.
UMS 10, FIG. 1, has been described to comprise two kinds of hardware, a CIU 20 and up to 32 RSCs 30,32 and 34. The CIU interfaces directly with the DI/Do lines of a factory environment control computer 2, and has up to 32 bidirectional serial data link connections, one to each RSC in the system. Each RSC includes its own power supply and I/O hardware. Functional electronics communicate with the CIU by a serial port with optical coupler buffer logic. The input and output signals are partitioned in four addresses of eight input and four output signals each, so that each input is directly compatible with a switch closure, TTI input, etc., and each output signal can directly drive other devices.
The combination of the RSC hardware and firmware accomplish input switch debouncing and continuous self testing. There is a hardware encoded unique RSC address and CIU channel address verification is provided. Error status is reported.
Each serial data link comprises a transmitter and receiver in each RSC and one of the 32 transmitters and receivers in the CIU. Cabling connecting each RSC to the CIU is preferably a four wire shielded cable. Data transmission may occur at hardware selectable rates varying from 75 to 9600 bps in eight steps. There is optical isolation between the CIU and plurality of RSCs. Data is ASCII encoded to include unique start and stop characters and a message check character. The transmitter is provided with a retry function on error determination and the receiver has a timeout function on error conditions.
In operation, UMS 10 of the present invention provides a CIU 20 for continuously polling all RSCs, recording their status and, upon demand from control computer to, transferring this information in a predetermined sequence to control computer 2. When the data transfer is complete, CIU 20 resumes polling and updating the status of the RSCs.
When control computer 2 requires information from CIU 20, a data transfer option is initiated by a set of commands, addresses and data. Each set of commands, addresses and data support a particular data command option.
Command A is a request for all data. Command B is similar to A except that only data changed from the last data transfer is required. Command C requires the input status of a particular address. Command D requires reporting the output status of the address in the request. Command E requests all self test errors and Commands F and G control the RSC outputs on the specified addresses to match the associated data.
When all requested information has been transmitted to control computer 2, CIU 20 sends an end of data response which includes system status information relating to normal end of data, any parity errors, self test error, invalid data transfer commands or timeout error, as shown previously in Table 5.
In order for any one of the serial communication links between the CIU and RSC to recover from communication errors, there must be a timeout wait after which the receiving device can resume normal operation. It is desirable that the length of the time out be associated with the selected communication rate.
In the present invention means is provided for measuring the duration fo the serial clock frequency as shown in FIG. 4. Only one signal need be monitored to determine the baud rate selected. A software routine, a flow chart of which is shown in FIG. 7A, measures the duration of the clock signal.
While the invention has been described in reference to a particular, preferred embodiment, it will be understood by those skilled in the art that changes in form and detail may be made without departing from the scope thereof.

5 Essential Filters For Digital Video Production....
Learn how to balance exposure, control depth of field, compensate for limited dynamic range, reduce glare, and control reflections with Century's new Essential-5 Filter Kit.
Created by the world's top maker of professional lens add-ons, these new Century Filters by Schneider Optics have been specifically selected to meet the unique needs of today's DV/HDV cinematographers.
The new series of five filtration tools combines top-grade materials, high-end performance and affordability. Century 4"x4" filters fit neatly into standard mattebox filterholders. This creativity booster is bound to become a valued cornerstone in every video professional's toolbox.
Century Filters may be purchased as a 5-filter kit, comes complete with a lightweight, multi-compartment padded pouch outfitted with belt loop for easy, hands-free toting. They may also be purchased separately, in a hard plastic box, designed for safe storage and protection.
Linear Polarizer Filter:
The Century Polarizer reduces glare and unwanted reflections, saturates colors, deepens blue skies, improves contrast, and penetrates haze. Polarizers are commonly used to control glare on water and to allow the camera to see below the surface. They are also used to reduce glare on car bumpers and to control reflections on plate-glass windows.
Neutral Density .6 Filter:
For the best handling of exposure. The ND .6 Solid Filter has a Neutral Density of 0.6 (2 stops), which reduces transmission by 75%. It can be used to control exposure or depth of field under various lighting conditions without affecting color or contrast.
ND .6 Soft Edge Graduated Filter Employs a surface that is 50% clear and 50% with a neutral density of 0.6. The shift from clear to ND is achieved with a SOFT EDGE (SE) transition line. The ND .6 Soft Edge Graduated Filter balances exposure within a scene for example, the exposure of sky and earth in a landscape, avoiding overexposed blank white skies.
Black Frost 1/2 Diffusion Filter:
For subtle enhancement of a scene, the Black Frost 1/2 Diffusion Filter may be used to flare highlights, mute colors, and tone down contrast, without degrading image quality or black saturation.
Skintone Enhancer Warming Filter:
The Century Skintone Enhancer Warming Filter adds warmth to skin tones and accentuates foliage and architecture while reducing excessive blue in outdoor open shade. The ideal tool for romantic close-ups, it can be effectively combined with Century softening filters.

About GRANDMANAN
By: GRANDMANAN, 10:41 AM GMT on June 30, 2008
Thick fog, cool at 10C, 10-15C SW with the threat of moisture before the day is out. Forecast poor for most of the week.
Emily out overnight, have not heard tell of Rob, but then did not expect he would be intouch. He knows where he is and what is going on and that is about it.
Quite a few last minute traps getting ashore yesterday. They are all out of the water, with the exception of the few guys that are fishing the 'greay zone'.
No local herring news, majority of the wiers on the front of the island to be built as yet. Jubilee in Whale Cove appears ready for twine, none of the others that far along. Dulsers have been busy, but this weather will curtail that activity for awhile.
By: GRANDMANAN, 10:52 AM GMT on June 29, 2008
Overcast, a little moisture down overnight, cool at 10C, no air moving whatsoever. This is the forecast for the next day or so, hopefully will straighten out for the CANADA DAY celbrations.
Wharves busy yesterday with traps coming home, by last night, not a soul around. Time for the crowd to catch thier breath. Good spring for the level of catch, disappointing for the price. All eyes will be on what price of fuel will be by fall, and what price lobsters might be.
See a couple of boats shucking scallops over the weekend, an area 'up the Bay' opened first of last week.
By: GRANDMANAN, 11:14 AM GMT on June 28, 2008
Overcast, brisk NE breeze, possible showers later on in the day, temp 13C. Not a great outlook for the holiday weekend.
Rob away till mid week at Oak Point, he was looking forward to the change, longer the better of course. Rmily finally on deck close to her usual self, lost 6lbs, on a frame that has none extra to give up.
Mom settled in at the hospital, looking and feeling the best she has for quite sometime. She will be going home once her diabetes can be settled, and a little more home support put in place.
Traps pretty well home I beleive certainly today will get most of them on the bank. Another lobster season in the books.
By: GRANDMANAN, 10:48 AM GMT on June 27, 2008
A little fog in the harbour, sultry, calm, 15C for temp. A chance of showers later on today, weekend starting out pretty nice. Mornng beverages watching the lighthouse on Ross Island come and go in the fog.
Rob a weekend with a friend a campground on the St. John River, he is looking forward to the change. Emily still struggling with the head cold and cough, seems to be making the slightest of progress to getting it behind her.
Mom returned to the island yesterday, now in hospital here getting sugar levels under control. Plan is to have her at home ASAP. She is doing well, especially for a person given at best a few hours to survive.
Traps will be home next couple of days, fellows will be glad to see the last of them for a little while. Have not heard of anyone going netting as yet, price not there to make it viable.
By: GRANDMANAN, 10:47 AM GMT on June 26, 2008
Warm, clear, slight draft from SW, temp already a pleasant 14C anticipate a similar day as yesterday, one to put in the weather books. Damp looking for the long weekend.
Traps coming ashore thick and fast this past few days. Most of the boats fishing everyday taking advantage of the calm weather, to get as many hauled as possible.
Wind farm meeting a positive experiance, they are intent on making the proposal from a number of years ago come to pass. It appears the wind generating project on the island is the furtherest down the road to completion than any other int he Province. The farm would generate more than sufficent energy to give Grand Manan the community powered totally by 'green energy'.
Emily still suffering, but appears to be on the road to recovery. Rob still holding on some of the 'plague', but did spend some time at the park yesterday.
By: GRANDMANAN, 10:51 AM GMT on June 25, 2008
One of those great weather days one can only enjoy on the island. Clear, a nice wessterly 10-15KPH, coffee on the verandah with temp 15C. A high into mid twenties in the foecast. Moisture in the offing for the rest of the week. These types of days makes it more than bearable - at least for a day or so.
Emily still confined to barracks, head cold refuses to give her any relief. This one that hangs on for a longtime, and is rampant in the community.
Wind farm meeting this morning, looking forward to hearing what they have to say. Any level of economic diversification is a welcome thing at this time.

No change in the weather, calm, very wooly, visibility maybe 1/4 mile, temp 13C. Looking for a little moisture and clearing later this week.
Emily suffering with a cold that refuses to give her any relief. Rob is on the mend, both didn't wander far fromt he fort yesterday, Donna forecasting a long summer if this remains the case.
Some construction underway besides the multi-plex, the contractors are busy. It is a time of year where little jobs are impossible to get looked at for consideration. At least one part of the economy appears in good shape.
By: GRANDMANAN, 10:45 AM GMT on June 23, 2008
Another thick fog morning, visibility less than 1/2 mile. Sun would like to make an appearance, but fog on the winning side so far. Temp a moderate 13C, no air moving whatsoever.
Wind farm reps to visit the island this week with a meeting with mayor and council members in the offing for Wed. The wind farm seemed to be a dead prospect,have been assured the plan is moving forward. No idea of what the economics of such a project may have, if any, for economic spin offs for the community. Anything to add to diversity economically would be great.
Last week for lobster fishing in Area 38 underway. Have not heard of anybody going netting, high fuel costs with low fish prices again hard to make it profitable.
By: GRANDMANAN, 11:08 AM GMT on June 22, 2008
Thick fog, attempting to clear ever so slight with a little breeze might get it out of the way. Temp 12C to rise high teens before the day is done.
Attending a conference in Fredericton since Thursday, returning home five thirty boat last night. Quite a few travelling with some tourists now in the mix, another yearly cycle in commence.
Kids done with school till Sept. very pleased with report cards, Rob made it to the hour roll. He has bragging rights for highest average till next report late fall.
Rob out overnight, and Emily had a babysitting job, summer routine has started.
Visited with mom while enroute to Fredericton she is holding her own, the level of improvement must be greater, in my opinion before she can return to her home.
By: GRANDMANAN, 11:50 AM GMT on June 18, 2008
Thick fog, calm, cool 11C, fog so thick almost a drizzle effect. Showers or T.Showers in the forecast. Clearing sometime tomorrow with better weather in the offing for the weekend.
School out at 11AM, as graduation taking place at Noon. The grads are going to PEI for a Safe Grad adventure. In the past have travelled across the border. The expense of travelling any distance a consideration, a sign of things to come.
Junior prom this evening, both Emily and Rob attending. Emily moving into high school and will participate in the Grand March, if she and her grandmother survive getting the hair done properly. Rob a typical male a little bit of hair off the top, new shirt, ready to socialize.
Project moving along with the next stage the pouring of the footings soon to be underway.

A much needed steady farmers rain this morning, calm, 13C for temp. This is the weather for the next 24 hours or so, amzing just how dry it has become in a short time.Fog attempting to make an appearance the tops of the trees on Ross Island starting to be obscured.
Lobster catch on the increase on the northern part of the fishing area, big time. Large catch helps, but with rising expenses an iffy situation to make a 'years work' from November to end of Jun. No sign of herring around the wiers, seiners have been getting a few on the banks, but nothing from Nova Scotia shore past little while.
Kids both less than 100%, too much sun over the weekend stil has lingering effects. They do get brighter in the morning as only a couple of complete days left of school.
Mom continues to improve, goal is now to get her back into her own home. This will be accomplished if she can regain her mobility to the level prior to her heart attack.

Overcast, a threat of rain, harbour millpond like, 14C to rise near twenty. Moisture next couple of days. Could use a little soaker lawn is bonde dry.
With price of heating oil being what it is loads of hardwood for stoves showing up this past week. Don't appear there will be any relief from the high prices for oil, a big concern for many people, heat or eat.
Emily out to another beach fire last night, till midnight. A good time had by all, last week of school. Senior prom tonight graduation on Wednesday, Otis to award the Ivan Green Memorial Scholarship. The amount of money in the award disappointing due to lack of return on investments by the trust, barley broke even, was expecting a few $K with the amount of funding in the account.
By: GRANDMANAN, 10:56 AM GMT on June 15, 2008
Overcast, a struggle to see if the sun will make it out, or will be getting the moisture right away. Temp 12C a steady breeze from NE 10-15KPH
Emily out overnight, beach bonfires the social event these days. Rob had a great time overnight on Ross Island, he declined a evening on the beach for movies and early bunk, did not see him last evening at all.
Fathers Day gathering the smallest one since we returned home, Donnas folks, the other attendees have left or in the hospital.
Yardwork is coming ahead, must get the lawn done prior to the impending rain - I have been advised.
By: GRANDMANAN, 11:06 AM GMT on June 14, 2008
A great weather day, temp already in high teens, calm, clear, mid twenties before the day is done. A little cooler with some clouds in the offing for tomorrow.
The overnight group on Ross Island had great weather, could hear them across the harbour whooping it up, quite a distance but calm. Didn't see a beach fire, but lots of lights after dark. No sign of them on the beach so far this morning.
Emilys' class spent the day on Whitehead, by the time she got home a severe sunburn. Claims she had sunscreen on, but doubtful. She wasn't around too much last evening, trying to get the burn to subside I imagine.
Got my potatoes in at Donnas' folks last evening now require the next hundred days to be frost free to get my crop.
By: GRANDMANAN, 10:49 AM GMT on June 13, 2008
Another fine summer day in the offing, a pleasant 15C, a slight draft from NW. A duplicate of yesterday, looking pretty good for the weekend.
Fuel price took another rise this week around 2.6% over last week, currently $1.397/litre locally. The CAD is dropping a penney or so to the USD, $.97 this morning.
Robs' class overnighting on Ross Island in a SURVIOUR contest. They are looking forward to the experiance, the weather is co-operating for them making the sleeping under the stars much better.
Lobster traps getting further up into the harbour, with quite a number there for the end of the season. Catch has been good, price still no better.
Mom doing well, and pleased to be in St. Stephen rather than St. John.
By: GRANDMANAN, 10:40 AM GMT on June 12, 2008
Clear, beautiful summer like morning, a warm 17C, a refreshing breeze from the west, just enough to keep the flag moving. Forecast for low 20's along the Fundy Coast, similar for next couple of days.
Mom transferred to the St. Stephen hospital, yesterday late in the day. All appear well she has to get some rehab for strength, before she can be considered eligble to for her home. Will wait and see how she makes out.
Lobster catch on the increase, however lots in the system. Other areas in the Maritimes having good spring seasons, some best in years.
Dulse group still hard at it, with Dark Harbour contributing a fair amount during this set of tides.
By: GRANDMANAN, 10:54 AM GMT on June 11, 2008
Typical June weather, all over the place, thick fog this morning, cool @11C, a slight breeze from NE. Calling for a clearing trend for the evening, and into the weekend looking good.
Fishery quiet at the moment with the last few weeks of the lobster season near. Price still poor, and no relief in fuel prices makes it along time till fall fishing.
Should have an idea on where mom will be transferred later on today. The heart issue is as good as it is going to bet, but her mobility in doubt. They will transfer her to this hospital, providing a bed is available, can't see her going to her home until she can at least get around on her own better than she is now.
School continues to wind down, homework is less with more of the courses being completed.
By: GRANDMANAN, 10:46 AM GMT on June 10, 2008
Overcast, calm, a slight draft from NE, temp dropped back a couple degrees to 12C. Looking for showers over next couple of days. Yesterday unusually hot for early June here mid twenties, seldom have those temps in July/August.
First Council Meeting with the new group went well. Starting to move forward with the complex, on just how it will be managed, expectations, policy and areas of responsibilty to be identified. The old building totally off the site as of yesterday.
The CAD has dropped a couple of pennies alongside the USD now in the 96cent range. Fuel costs a major topic of discussion wherever one stops to catch up on what is taking place.
Kids slowly getting into summer mode, school pretty well done by the end of this week. Prom night on 18th, both of ours attending the junior rendition of the evening.
By: GRANDMANAN, 10:42 AM GMT on June 09, 2008
Idyllicy summer morning, total calm, clear with a hint of haze in the harbour, 15C with a forecast high into the mid twenties. Nice weather week in the offing with a hint of moisutre a couple of days down the road.
A morning with coffee on the verandah, a couple of boats hauling traps in the harbour. Could almost hear the plants growiing, taking advantage of the ideal growing conditions.
Record breaking temps down the seaboard in Boston and New York flirting with temps in the 100F for today. Plenty hot for any part of the country, into the low 30'sC inland yesterday, low 20's here, warmer in North Head. Great fly hatching weather.
First meeting of the new Council this evening.
By: GRANDMANAN, 10:47 AM GMT on June 08, 2008
Thick fog, calm,12C for temp, U.S. forecaster giving in mid twenties for Lubec, Canadian guy says high teens, will wait and see who is reading the tea leaves correct. Giving nice temps for the next week.
Mom still holding her own, no word when the anticipated move to our hospital will take place.
Yardwork going along pretty well, Donna has her window boxes on the house, now various pots to plant along with some annuals in the regular flower garden. This type of weather brings things on in a hurry.
Kids have a couple of weeks left of school, they are getting geared up the summer. Emily looking for babysitting, and Rob looking for lawns to mow in between the social commitments they maintain.
By: GRANDMANAN, 10:43 AM GMT on June 07, 2008
Ovecast, calm, 10C, forecast high teens, possible shower. Hot and humid for tomorrow into the first of the week, unusual for this early in the season.
Mom certainly has improved over the week, from a near death experiance to waiting for a transfer to our hospital qite a transition. She is quite content where she is for the moment at least.
Emily has overnight guest, Rob had been out to a birthday party/air soft war till dark. Both very busy to say the least.
Boat traffic heavy both trips I was on, and sevral vehicles went out on the last trip. The 'late trip' getting more use as the summer season begins to unfold.
By: GRANDMANAN, 9:16 AM GMT on June 06, 2008
Calm, overcast, harbour a reflecting pond this morning. Nice sunrise, but clouds making up, rain expected before the day is over, moisture for the weekend.
Lobster catch getting better, but price dropping back below $5/lb. Did notice the price of diesel did move back five cents, regular fuel no change @$1.55 & $1.35/litre respectivly.
Second stage of the removal of the buildings on the construction site moving along. Removing some of the salvagable lumber,fixtures, etc. before walking through it with big machines. Site taking shape, getting prepared for the cement work.
Off to St. John visit mom have a look for myself how things are going. Reports have been positive since she was transferred there.

Overcast, brisk NE breeze, steady 10-15KPH, 11C, partial overcast and high teens for temp in the forecast. Similar type of weather for next couple of days.
Drain tides, bar seems to be out there almost to Ross Island, no clammers on the beach this morning. Mike telling me yesterday that had around 40K lbs dulse processed, with market for that much and more. Dulsing giving the local economy a shot at around $4/lb a welcome source of income for those involved.
Mom continues to make progress, no fluctuations in heart beat and blood pressure steady. No decision on pacemaker as yet. Will make the trip to visit with her tomorrow.
By: GRANDMANAN, 10:47 AM GMT on June 04, 2008
Overcast, total calm, temp 11C. Raining on the mainland in the forecast here today and rest of the week.
Tides are fulll, see a couple of clammers at it this morning, not the activity of a few weeks ago. Either more employment has showed up or those folks have had to move on. Has been a steady run of dulse going by the house this past few weeks. A large amount has been harvested from the Passage, price is good. See one sign for $7/lb.
Emily has a lot of homework to get the required schoolwork in due to the number of missed days over the winter. Rob seems to get his done at school, or that is his story, soon will know.
Windowbox planting underway, not on display as yet, in the shed getting used to thier new digs prior to a direct shot to the elements.
Mom holding her own, possibly a pacemaker by Friday, final decision yet to be made.
By: GRANDMANAN, 10:39 AM GMT on June 03, 2008
Clear, calm, a sultry 14C, fog disappating in the harbour. A heavy dew this morning, giving rain later on in the day, lots of moisture for the week.
Mom still confined to hospital, no word on when the next move will take place. Her symptons still up and down, evaluating the benefits of a pacemaker.
Great weather day yesterday, warm, slight breeze, after supper overcast and cool. Rob had a baseball practise but still lag from weekend concert, not into it all.
Some fresh bait going yesterday, don't know if it is from the sieners or if the wiers might have caught some either here or Nova Scotia.
Project well underway, one end of the building is gone, ground getting ready for the first of the cement.
By: GRANDMANAN, 10:46 AM GMT on June 02, 2008
Farmers rain this morning, calm, 11C, to clear as the day moves along with rain overnight. Sun and moisture the forecast of the week.
Rob has not given a complete report of his weekend gig as yet. He arrived home on the 2nd trip, said all went well laid down slept till bedtime. One comment is that he did not have enough money as they went out often to eat.
Last few weeks of the lobster season now underway, catch is coming up some, but not the price. Work on the wiers ongoing, some have been dressed for the short term, don'at believe any have captured any as yet. Connors must soon be ready to pack as they have been shut down for the past few weeks getting ready for another packing season.
By: GRANDMANAN, 11:04 AM GMT on June 01, 2008
Overcast, fog just leaving the harbour, a stiff southerly around 20KPH, 10C temp. Looking for some clearing possible this afternoon, rain for most of the week, no sun in the froecast till Friday.
Mom holding her own, things appear to be more steady this last 24 hours. Dr. is continuing to monitor with the possibility of a pacemaker being the answer. A long way from when she first entered the system, at that time just keeping her comfortable was the goal.
Donna to get a start on window boxes next week, she has a plan, now to put it in action will be the thing.
Part of the old B&G Club has been removed, the remaining structure will be removed witin the next couple of weeks. Site prepartation coming along very well, cement work not far off.

If you haven't seen Disney's Oscar-nominated animated short "Paperman," you're missing the most romantic movie of the year.
The irresistible six and a half minute short directed by John Kahrs played in theaters before last fall's hit "Wreck-It Ralph" (also up for an Oscar in the animated feature category). It was conceived in part to test a new animation technology developed by Disney called Meander, which blends the flexibility and expressiveness of 2D drawing with the precision of computer generated animation.
We're rooting for both "Paperman" and "Ralph" to take home Oscars on Feb. 24, but either way it's great to see Disney make "Paperman" available for free viewing online to expose it to as wide an audience as possible.
Check it out in the player above (we recommend clicking the full screen option to maximize the beautiful animation).

Over 70% of patients whose lung cancers harbor specific mutations within the exons encoding the tyrosine kinase domain of the epidermal growth factor receptor (EGFR) experience radiographic responses to the selective EGFR tyrosine kinase inhibitors (TKIs), gefitinib (Iressa) or erlotinib (Tarceva). However, after about one year, these patients develop progression of disease. No targeted therapy has proven clinically effective in treating acquired resistance. In the previously funded period, we identified several mechanisms of acquired resistance, including second-site EGFR mutations (>50% of cases) and amplification of the gene encoding the MET tyrosine kinase (up to 20% of cases). Using mouse models of lung cancer that we generated and characterized, we also showed that the most common form of resistance, mediated by the EGFR T790M mutation, could be overcome by a novel combination of the second-generation EGFR TKI, afatinib (BIBW2992), and the anti-EGFR antibody, cetuximab. A Phase IB/II clinical trial of this combination in humans has now shown unprecedented activity in this patient cohort with a 36% (8 of 22) radiographic response rate. However, at least one patient on this combination has already developed progressive disease, and surprisingly, some tumors without T790M have also responded. The overall goals of this revised proposal are to use human tumor specimens and cell lines, genetically engineered and xenograft mouse models, and various molecular and biochemical techniques to gain further knowledge about the subset of EGFR mutant harboring lung cancers that develop acquired resistance to EGFR inhibition. An improved understanding of acquired resistance will hopefully allow us to treat/suppress the development of progressive disease and provide new insights into the biology of cancers driven by EGFR or other mutant receptor tyrosine kinases.
A new clinical trial involving two targeted agents (afatinib plus cetuximab) was rationally designed based upon findings from our previous funding period and has now shown unprecedented anti-tumor activity in patients with acquired resistance to EGFR tyrosine kinase inhibitors in lung cancer. The goal of this grant is to gain further knowledge about the subset of EGFR mutant harboring lung cancers that develop acquired resistance to EGFR inhibition. An improved understanding of acquired resistance will hopefully allow us to treat/suppress the development of progressive disease and provide new insights into the biology of cancers driven by EGFR or other mutant receptor tyrosine kinases.

: Stopping Attacks in Their Tracks"> eWeek: Whats the thinking behind the virtual patch technology? Klaus: Over time, people have become dependent on vendor-released patches as the first line of defense. But the average amount of time it takes to get one of those out is about six months from the time the vulnerability is found. We can provide the same kind of protection on the agent without affecting the underlying application. The standard security expert answer has been to go and turn off whatever services youre not using. But that can take a long time and sometimes you have to go into the registry and mess around and you never know what can happen. So we said, lets just block it instead of turning it off. Its much easier, its cheaper and its just as effective. It can prevent attack packets from getting to the target. Its the same protection level as a patch without really changing the system. We just need to make sure were accurately detecting the packets. Our goal is to reduce false positives to zero.Klaus: Yeah, were investing in a lot of technologies to detect unknown attacks. We cant prevent everything. But anyone who tells you they can detect them all is selling snake oil. Were just at the beginning of all of this.
eWeek: The protection against unknown attacks is clearly a big part of this.

On Saturday 28 November 2015, Justin Glyn SJ will be ordained as a deacon at St Carthage's Church in Melbourne.
Justin was born in Namibia and grew up in South Africa before migrating to New Zealand in his late 20s. He has a doctorate in law, and worked as a corporate lawyer before joining the Society in 2009.
Michael McVeigh spoke to Justin ahead of his ordination.
When did you realise you had a calling to the priesthood?
I felt called to the priesthood from my childhood, but I don't really think I understood what that was really all about for quite a while. I was going to join the priesthood straight away when I left school, but very wisely I was told to hang on until I had some experience.
I practised law, and gradually the feeling returned that I was meant to be somewhere else. I felt strongly drawn to the priesthood again.
I came across the Jesuit spirituality, particularly the understanding of God in all things, and the sense of finding God everywhere. I realised that this was where I was meant to be. As a result, I joined the Society in 2009.
What was it about the Jesuits that drew you to them in particular?
There were a number of factors. I was absorbed by Jesuit poets like Southwell and Manley Hopkins, and I'd read the Jesuit philosopher and theologian Teilhard de Chardin.
At the same time I came to a deeper appreciation of the Jesuit spirituality, which sees religious life as not something divorced from the everyday, but something that's tightly interwoven with it.
Those things drew me really closely towards an understanding of what it might mean to live in relationship with Christ, who's also at the same time moving in the world around me.
As part of your regency, you spent some time with Jesuit Refugee Service. What were some of the things that came out of that experience for you?
I'd been a person whose first instinct was to get out and be doing. I found that in the pastoral world, you don't really get out and do. The key is being with people and living in relationship. It's sitting with people who are hurting, and being present to them.
It was very different to the world I'd been in as a corporate lawyer, or as a legal academic.
Were there any moments or experiences that really resonated with you?
Talking to people who find themselves absolutely at their wits end — what I think of as the Gethsemane experience of being an asylum seeker but not knowing where the next meal's coming from, whether you're going to be sent back. There were a few occasions where I sat with people and what I was hearing was absolute despair. There was a sense of tension, but a tension that was completely beyond them to resolve.
I had a few occasions like that, and those instances of just sitting with people, listening to them share where they were at, were probably some of the most powerful memories of regency.
You've been writing fairly regularly for Eureka Street. Is that something you see as part of your ministry?
Very much so. I don't think ministry is something that happens just up on the altar, or in some area or another. I think ministry is something that happens wherever one is.
Engagement with the world is something that is a real strength of Ignatian Spirituality, but it's also a real challenge because it means that every part of us is called on. God doesn't actually call on little bits of me. He calls me to give what I have. Whether it be presiding at the altar, or whether it be writing, or whether it be singing — all of these things I see as being part of a life I'm called to use.
Ordination will give you a much more active role in liturgy. What is it about liturgy that's important for you, and what do you think makes a good liturgy?
To some extent that active role is something we all share. The Vatican Council talks about the full, conscious and active participation of everybody, so to try and delegate the role of liturgist to the priest is not necessarily a great idea. But it is true that as a deacon or priest I will be called on to lead worship and to help other people engage in it in a deeper way.
A lot of that comes back to the pastoral work. Knowing where people are at, and helping people engage in a liturgy that is meaningful, and in which they can feel free and open, and able to feel the presence of God.
It's not the easiest time to become a priest in the Catholic Church. What are your thoughts on the Church's current struggles?
We tend to think of the Church as being an 'out there' thing — a hierarchy. There certainly is a hierarchical structure. But ultimately we are the Church, and that's all of us — priests and laity.
People who enter into the priesthood and the diaconate do so as representatives of the Church as a whole, and I think that we have forgotten that. The abuse crisis is a dramatic example of where people in authority have betrayed that trust. But at the same time there is a Christian faith community in whom God works, and I think that the call to priesthood is a call to be part of that, and to be open to wherever we're called to go with God.
It's impossible to impose an image on the priesthood. But a lot of it is an attitude of how we come to serve.
How does it feel to be entering into this next stage of your journey?
It's hugely exciting. I'm thrilled to bits. It's the culmination of everything I've been propelled towards and been developing towards over the last 43 years. But I'm also acutely aware that it's a huge trust being reposed, by the Society, by the Church at large, by the people who surround me and who've brought me to this point, and ultimately it's a trust reposed by God. And I think that's something I'm increasingly aware of as I come up to the ordination.
I don't think this is me doing "my" thing, I think it's something where I'm buoyed up and brought along as part of a community. It's something where I know I don't have all the answers. I'm assuming I'm being directed by God, and I'm trying to keep a couple of open ears to see which way I'm being directed, and how that will work out in practice.
Listen to the full interview with Side and his fellow ordinand Justin Glyn SJ, at PrayOnline. Read Province Express's profile of Side here.
Submitted feedback is moderated. Email is requested for identification purposes only.
What a wonderful interview! Justin Glyn's enthusiasm for and his enjoyment in his vocation to become a priest in the Society of Jesus come through most vividly. May God bless him and his work in the Society of Jesus.
I worked for a short time with Justin in JRS and was very inspired by his pastoral gifts relating to all people especially asylum seekers and refugees of whom he wrote about with great empathy in various articles.
A mission to educate
On Saturday 28 November 2015, Sidelizio Pereira SJ will be ordained as a deacon at St Carthage's Church in Melbourne. Born in Baucau, East Timor, Side's Catholic faith was formed by the Salesians as he attended the Salesian youth program as a young boy and teenager. He later attended the Jesuit-run school in Dili and was educated by them. Michael McVeigh spoke to Side ahead of his ordination.
