Title: Method of and apparatus for processing data at a remote workstation
Inventor: STRATIGOS WILLIAM N
IPC: H04L29/08
Filed: 1994-12-19
Abstract: A method and apparatus for processing at a remote worksta-tion (14), data files that are compressed and collected into groups on a local area network (10) at a central location. The files of a group are transferred to the workstation over an ISDN switched telephone network (22) in response to automatic requests from the workstations. The workstation requests depend on unprocessed files at the workstation as well as the time and date in order to reduce the connection time. When files are received at the work-station the first is immediately decompressed and presented to the operator. In the meantime the next file which the operator is ex-pected to need is decompressed in the background and is ready for processing as soon as the operator finishes with the first. When the operator switches to the next file the processing results are automatically saved and a further file is decompressed and held in a queue for the operator.

Patent CA-2191289-A1 (CA)
Title: Beverage dispensing system with bottle identification rings
Inventor: LOEHRKE JOHN M
IPC: B67D3/00
Filed: 1996-11-26
Abstract: Each open liquor bottle in a tavern has a plastic spout with a magnetically operable valve to control the flow of liquor from the bottle. The spouts were fabricated with three integral rings extending around the spout with each ring being either plastic or metal to form a pattern that encodes information identifying a characteristic of the bottle. An annular actuator reads the pattern of rings and responds by producing a magnetic field that opens the spout valve to dispense the liquor. Three rings allow up to eight different classes of characteristics to be encoded. To increase that number of classes a supplemental metal ring is attached around some of the spout adjacent to one end of the actuator when the spout is inserted therein. The actuator is modified to sense presence of the supplemental metal ring on a spout. Adding another ring to certain spouts permits the number of classes of characteristics to be doubled without requiring replacement of existing spouts in a tavern.

Inventor: RICE DANIEL S
IPC: H04N1/393
Filed: 1996-11-26
Abstract: A method for scaling images by a factor of two. Two variables are extracted from an unaligned input stream. The variables are selectively interleaved. The high and low order bytes of the results of the interleaving are multiplied to convert to a 16-bit representation. Horizontally interpolated data is generated by adding pairs of this conversion. The previous iterations of horizontally interpolated data is retained in buffers. Vertically interpolated data is formed by adding current and previous horizontally interpolated data together. The horizontally interpolated data is then doubled to maintain equal precision between the vertically and horizontally interpolated data. A packing function is employed to convert the data back to aneight-bit representation for output to the destination. Because the precision is the same, a single implicit divisor in the packing instruction handles both horizontally and vertically interpolated data.

Patent CA-2202439-A1 (CA)
Inventor: SMITH GREGORY W
IPC: F16C32/04
Filed: 1997-04-11
Abstract: A magnetic bearing system must rely on position feedback information for control. Position signal noise degrades performance of the magnetic bearing control and avoidance of the introduction of noise can result in increased controller performance. A digitally controlled magnetic bearing system requires anti-alias filtering on all sampled channels to attenuate noise above the Nyquist rate to a low level, compared with the position signal. One cost of signal filtering is signal phase loss which diminishes the performance of a real time control system as used in magnetic bearing. Significant noise often originates from switching amplifiers common in magnetic bearing systems. The scheme presented reduces the degree of filtering, including anti-alias filtering, required to attenuate a significant component of noise originating from switching amplifiers.

Title: Multiple channel, multiple scene dimming system
Inventor: FLOYD ROBERT ANTHONY
IPC: H05B37/02
Filed: 1997-05-09
Abstract: A lighting control and dimming system 10 utilizes a single traveler conductor 28 for transmitting analog data signals corresponding to a particular light intensity level of dimmers DIM 1, DIM 2, DIM 3, DIM 4,  ..., DIM N in a dimmer group.   A predetermined binary data word is retrieved from the read-only memory of a controller 30 that may be remote from the dimmers, and is transmitted serially in an analog pulse train over the traveler conductor to each dimmer unit.  Each dimmer unit includes a microcontroller 78 and read-only memory (EPROM) 60 in which a group of binary numbers are stored.   The analog data signal received by each dimmer is converted to binary and is compared bit-by-bit with each binary number stored in the dimmer  EPROM memory  60.   A serial  bit  comparator  72 produces an enable signal 106 in response to a bit-by-bit identity match between the converted analog data signal and the preset binary number  stored in the dimmer EPROM.          Dimmers enabled by the transmitted analog data signal produce a predetermined scene at a particular brightness level corresponding with one of the stored binary numbers.
