Patent CA-2395389-A1 (CA)
Inventor: SCHILLER JAY B
IPC: H04N7/24
Filed: 2001-01-12
Abstract: A method and apparatus for identifying an appropriate video signal path is provided for delivery of VOD data to a subscriber in a VOD system. The signal path (146) may be a portion of a hybrid fiber optic and cable (HFC) network so that other signal paths in the HFC may service subscribers in other areas.  Because each path need not service every area, the total bandwidth provided by the VOD server (106) need not be provided to every area so that the bandwidth provided to each area can commensurate with the needs of that area. When a subscriber Plant A requests VOD programming, the identification received by the subscriber's terminal from the VOD server is returned to the server along with the subscriber's request. From the identification, the VOD server may determine the area of location of the requesting subscriber and the VOD server may then transmit the requested programming to the area of the subscriber's location.

Title: Dual band framing reconnaissance camera
Inventor: PARTYNSKI ANDREW J
IPC: H04N5/232
Filed: 2001-07-26
Abstract: An electro-optical roll-framing camera (36) is described in which successive overlapping frames of scene imagery (1-5) are generated by an electro-optical imaging array (300). Image motion compensation is performed electronically to stop or freeze image motion caused by the roll motion. The image motion compensation is performed by the array (64) during the generation of the frames of imagery (1-5). The successive frames of imagery (1-5) are made during a continuous roll motion of the entire camera. The image motion due to roll is stopped or frozen without mechanically stopping the roll motion. The roll framing cycles (1-5) of the camera generate sweeping coverage of the terrain of interest (42). The roll rate for a given electro-optical array (300) is a function of the frame size and the framing rate, and is controllable by a master control computer (34). A novel catoptric Cassegrain optical system (50) which performs forward motion compensation is also described.

Title: Fuel cell resuscitation method and apparatus
Inventor: GIESECKE BENNO
IPC: H01M8/04
Filed: 2002-07-25
Abstract: A fuel cell system includes fuel cells forming a fuel stack, having a fuel passage and an oxidant passage. A purge valve is coupled to the fuel passage to exhaust contaminants, and a controller is coupled to temporarily increase the oxidant stream flow rate through the oxidant passage, and to temporarily open the fuel purge valve, if a voltage across a pair of fuel cells is less than a defined threshold voltage. In this resuscitation step, the oxidant flow rate can be temporarily increased by increasing a duty cycle of an air compressor by approximately 50% for a duration of between approximately 5 to 10 seconds. The controller can further shut down fuel cell operation if a voltage across a pair of fuel cells is less than a defined threshold voltage in an inter-resuscitation period immediately following the resuscitation step.
