Patent CA-2109520-A1 (CA)
Title: Video signal decompression apparatus for independently compressed even and odd field data
Inventor: NG SHEAU-BAO
IPC: H04N19/895
Filed: 1992-03-12
Abstract: In a video decompression system for decompressing compressed image data wherein odd and even fields of video signal are independently compressed in sequences of intraframe and interframe compression modes and interleaved for transmission, the odd and even fields are independently decompressed. During intervals when valid decompressed (45, 46) odd/even field data is not available, even/odd field data is substituted (47-51) for the unavailable odd/even field data. Independently decompressing the even and odd fields of data and substituting the opposite field of data for unavailable data may be used to advantage to re-duce image display latency during system start-up and channel changes.

Title: Data compression method and apparatus for waveforms having recurring features
Inventor: HORSPOOL ROBERT N S
IPC: G06T9/00
Filed: 1994-09-19
Abstract: An apparatus and method for compressing an input sequence of data items produced by sampling a periodic waveform compresses such input sequence by searching a history buffer operable to store consecutive data items, to locate a stored sequence of consecutive data items matching the input sequence. Matching is deemed to occur when each data item in the input sequence is within non-equal upper and lower limits of its corresponding data item in the stored sequence. When a stored sequence matching the input sequence is located compressed output data is produced to represent the stored sequence and the stored sequence is again stored in the history buffer to succeed the data items already stored therein. When a stored sequence matching the input sequence is not located, a representation of the first data item in the input sequence is produced and the first data item is stored in the history buffer to succeed the data items already stored therein. In addition, there is disclosed a system employing the above compression method in combination with a decompression method.

Title: Pilot relay valve with load piston
Inventor: JOHNSON DUANE RICHARD
IPC: B60T15/18
Filed: 1992-07-31
Abstract: A relay valve (10) for a fluid pressure braking system includes a relay piston (16) and a load piston (34) which is responsive to the pres-sure at the inlet port (38) of the relay valve to ex-ert a biasing force on the relay piston loading the latter against the inlet/exhaust valve (56). The bi-asing force is opposed by fluid pressure at the in-let port acting across the effective area of the in-let/exhaust valve. The biasing force is greater than the spring force holding the inlet/exhaust valve closed, so that the valve responds immedi-ately to pressure signals transmitted through the control port of the relay valve.

Abstract: A method and apparatus for preparing and steam-cooking shrimp in a microwave oven comprises placing peeled and deveined shrimp in a steaming tray having a base unit and a snap-on lid.  The shell of the shrimp may  be  mechanically  loosened,   and  the  shrimp mechanically deveined.   The loosened shell is then removed,  leaving  the  last  joint  of  the  shell, surrounding the tail area, intact.  The base unit has individual   shrimp   compartments   formed  therein. Channels are formed in both the base unit and the lid for conveying steam around the individual shrimp during cooking, and to provide additional structural integrity to the apparatus.   The shrimp compartments are of a size and shape to conform to the shape of uncooked shrimp,  and thereby prevent the shrimp from curling when it is cooked.  Spices or marinades may be added to the shrimp compartments prior to cooking.

Title: Adaptive cleaner blade lubrication
Inventor: MINAGAWA GARY A
IPC: G03G21/00
Filed: 1994-10-25
Abstract: An adaptive cleaner blade lubricating system for electrophotographic printing machines. In an electrophotographic printing machine, the amount of residual toner available to lubricate a cleaner blade is calculated based on the density of the transferred image. A band of toner is deposited in an inner document gap in selective widths so as to provide an adequate amount of toner to lubricate the cleaner blade across the full width of the photoreceptor. The lubricating band may be variable or may be a constant width with the frequency of placement of the band determined based on average image density for a group of documents. In the preferred embodiment, the width of the toner band is varied as a function of the overall residual toner in each pixel location across the width of the photoreceptor based on the density of the images transferred. As a result of the varying lubrication bands, the cleaner blade is maintained so as to not tuck and cause streaking and/or damage while toner efficiency is maximized.

Inventor: HOLMES ANN R
IPC: C12Q1/6806
Filed: 1993-05-18
Abstract: 2136206 9323568 PCTABS00028 This invention is directed to methods of diagnosing fungal infections through the detection of distinct regions of the genome of pathogenic fungi. A first region of the genome is the 5S rRNA gene of such fungal organisms. This region is a conserved region for all pathogenic fungal organisms and its presence in a clinical sample is diagnostic of a fungal infection but not diagnostic of the species of fungi present. The second region of the genome is the non-transcribed spacer region of the rRNA repeat unit of such fungal organisms. This region is species-specific for each pathogenic fungal organism and its presence in a clinical sample is diagnostic of infection by that fungal organism. The methods of the invention provide for the detection of either or both genomic regions, as well as for the extraction of genomic DNA from fungal organisms. Also provided are nucleic acid probes and primers which bind to the distinct genomic regions, as well as diagnostic kits including such probes and/or primers.

Abstract: In a communications system comprising a number of base stations, each base station communicating over a shared communication channel with a plurality of registered stations and controlling the network cell formed by said plurality of registered stations, a method is described for dynamically registering and deregistering mobile stations. Each station owns a unique address and is allocated a local identifier at registration time. Each network cell owns a unique cell identifier known to all registered stations belonging to this network cell. Base stations manage cell members data uniquely associating the unique address and the local identifier corresponding to each one of the mobile stations belonging to their network cell. A registration request is sent to a selected base station by a registering mobile station, comprising the unique cell identifier of the network cell controlled by the selected base station and the unique address of the registering mobile station; the selected base station detects in its cell members data any conflicting registered station whose unique address matches the unique address of the registering mobile station and sends an address check packet to any conflicting registered station, comprising the unique address of the conflicting registered station, its local identifier and the identifier of the network cell it controls. A receiving registered mobile station sends to the selected base station, an acknowledgement to the address check packet if its unique address, the local identifier of its owning base station and its network cell identifier all match with the ones carried by the address check packet. The selected base station rejects the registration request it it receives an acknowledgement to its address check packet. The same address check packet is used to deregister inactive stations. <IMAGE>
