Title: Heat engine
Inventor: CHRISTENSEN RICHARD N
IPC: F02C6/18
Filed: 2000-12-15
Abstract: A heat engine (10) achieves operational efficiencies by: 1) recovering waste heat from heat engine expander (14) to preheat heat-engine working fluid, 2) using super-heated working fluid from compressor (402) to preheat heat-engine working fluid, and 3) using reject heat from condenser (93) and absorber (95) to heat the heat-engine boiler (12). A dual heat-exchange generator (72) affords continuous operation by using gas-fired heat exchanger (212) to heat generator (72) when intermittent heat source (40), e.g., solar, is incapable of heating generator (72). The combination of heat engine (10) and absorption and compression heat transfer devices (60, 410) allows use of low- temperature heat sources such as solar, bio-mass, and waste heat to provide refrigeration, heating, work output including pumping and heating of subterranean water and electrical generation.

Patent CA-2407616-A1 (CA)
Title: Fluoroscopic tracking and visualization system
Inventor: KAPUR TINA
IPC: A61B19/00
Filed: 2001-04-30
Abstract: The system (10) includes a fluoroscope (20), a work station (30) having one or more displays (32) and a keyboard/mouse or other user interface (34), and a plurality of tracking elements T1, T2, T3. The fixture, image detector, trackers, are secured to provide position data regardless of movement. A  detector identifies the markers, and a processor models the projection geometry to form a corrected image and position. A distortion corrector converts the tracked tool location and displays it on the image.  Alternatively, the fluoroscope takes each camera model frame and defines and registers a common center coordinate in the imaged tissue. The processor then filters and back-projects the data, forms a tissue volume set, and constructs patient planar images. The images may be registered to preoperative MRI, CT, or PET 3-D data, or without preoperative imaging. The tracker employs electromagnetic trackers to determine the coordinates of the components. BBs also implement the calibrator in a radiolucent foam using microlithographictechniques.

Filed: 2002-11-20
Abstract: A method of verifying identity which includes recording coordinates of a reference signature which include two dimensional space coordinates x and y exerted by a writer's writing instrument on a recording medium. The method measures and records an indicium, which identifies a reference biometric within the reference signature having a selected characteristic. Next the reference biometric and the indicium are placed on a portable, readable substrate. The coordinates of an unknown signature which include two dimensional space coordinates x and y covered by a writer's writing instrument are also recorded. The method further includes reading and storing the indicium and the reference biometric in memory and using the indicium to locate an extracted biometric within the unknown signature. The extracted biometric is compared to the reference biometric to determine if they match within predetermined threshold criteria. The reading and storing or the reference biometric and indicium, the recording of the unknown signature, the location of the extracted biometric, and the comparison of the reference and extracted biometrics are all performed on-site.

Title: Regeneration of program clock reference data for mpeg transport streams
Inventor: NEMIROFF ROBERT S
IPC: H04N7/26
Filed: 2001-08-31
Abstract: A system for providing an accurate time reference for multiple input and output digital video signals of a transcoder (100) that is particularly suited for use with MPEG data. The multiple streams are synchronized with a single master system time clock (155) at the transcoder (100). Timing data from the master clock is compared to timing data from packets that are input to the transcoder to determine an offset (120, 130). In particular, timing data, such as a program clock reference (PCR) field, is recovered from packets (104) of different channels that are input to the transcoder (122, 132). For each channel, timing data is then provided for packets (106) that are output from the transcoder based on the offset and timing data of the master clock (155) at the respective output times. In particular, the adjusted timing data is determined as a sum of the offset and an associated hardware error, less a delay (PcrSysDla) associated with the transcoder, which includes a lookahead delay and a buffer delay. The associated hardware error represents an error of the master clock and/or a system time clock of an encoder that encoded the particular channel.
