Patent CA-2322768-A1 (CA)
Title: Optical biopsy system and methods for tissue diagnosis
Inventor: WILSON SCOTT R
IPC: A61B10/00
Filed: 1999-03-09
Abstract: A system characterized tissue using fluorescence spectroscopy, such as light-induced fluorescence. Native fluorescence ("autofluorescence") from endogenous tissue without requiring fluorescence-enhancing agents is used to distinguish between normal tissue, hyperplastic tissue, adenomatous tissue, and adenocarcinomas. The system provides endoscopic image enhancement for easy location of a tissue site for optical biopsy tissue characterization. The system allows the use of an integrated endoscopic diagnosis and treatment device for immediate diagnosis and treatment without interchanging equipment and relocating the tissue site. The system is also integrated with existing endoscopy equipment for initiating and displaying the diagnosis. The system provides an adjunctive tool to histopathological tissue classification or, alternatively, further treatment is based on the optical biopsy system diagnosis itself.
Patent CA-2323104-A1 (CA)
Inventor: KRAVIS STEVEN F
IPC: H01T13/60
Filed: 1999-03-30
Abstract: An apparatus includes a power supply for supplying power to an ignition coil to generate a spark across a spark plug. A capture circuit captures an energy signal reflected from the ignition coil in response to the spark generation. A  comparator circuit compares the captured energy signal to a predetermined signal. The ignition coil includes a first winding in electrical communication with the power supply and a second winding in electrical communication with the spark plug and, thus, the energy signal is reflected from the first winding of the ignition coil in response to the spark generation. The predetermined signal represents one of a distinct group of reflected energy signals which indicate various defects in the ignition coil or spark plug. Preferably, the comparator circuit generates an output in response to a match between the captured energy signal and the predetermined signal to indicate a defective ignition coil or spark plug. A method includes the steps of: supplying power to an ignition coil to generate a spark across a spark plug; capturing an energy signal reflected from the ignition coil in response to the spark generation; and comparing the captured energy signal to a predetermined signal. Preferably, the method further includes the step of generating an output in response to a match between the captured energy signal and the predetermined signal to indicate a defective ignition coil or spark plug.

IPC: G06F1/32
Filed: 1999-04-20
Abstract: A method and apparatus for reducing power consumption of an auto-negotiating ethernet transceiver by enabling a driver for the transceiver to alternate between a typical higher-power energy consumption mode (12) to a lower-power energy consumption mode (26) when a network link is no longer detected by the transceiver. The driver causes the portable computer to send instructions to the ethernet transceiver so that the transceiver continues to check for the network link (16). If the network link (16) is not detected, the driver causes the ethernet transceiver to power down into a lower power consumption mode (26) for a specific period of time (28). After the period of time has elapsed, the driver causes the ethernet transceiver to enter a normal higher power consumption mode (32) during which the ethernet transceiver again checks for the network link (16).

Abstract: A relative motion generator (10, 20) capable of dynamically varying an acceleration, velocity, displacement, dwell time and/or location of the dwell of a continuously moving line (11, 24) within a working region (16, 26). The relative motion generator (10, 20) is particularly suited for indexing the continuously moving line (11, 24) past one or more work stations (17, 50, 52, 54, 56). The continuously moving line (11, 24) may be either a conveyor belt, a parts handling system containing discrete components, a chain drive, or a continuous web, with or without discrete components. The relative motion generator (10, 20) includes first and second support member (13, 14, 34, 36) mounted to the slider assembly (10A, 32) adapted to support a working region (16, 26) of the continuously moving line (11, 24). A programmable actuator system (40) is adapted to move the slider assembly (10A, 32) along the translation path (18, 38) to generate a working region motion different from a nominal motion. The working region motion is the same as a nominal motion when the slider assembly (10A, 32) is stationary relative to a fixed location (17).  The translation path can be circular, linear or curvilinear.

Title: Preparation of metal-matrix composite materials with high particulate loadings by concentration
Inventor: DOUTRE DON ALLEN
IPC: H01L23/15
Filed: 1999-08-06
Abstract: A composite material having less than about 25 volume percent refractory particles in a metal matrix is concentrated to have about 37-45 volume percent refractory particles. The concentrating is preferably accomplished by heating the composite material to melt the matrix, and then contacting the molten composite material to a porous element having an average pore size greater than that of the average particle size. A small pressure differential, on the order of about one atmosphere, is applied across the porous element, so that metal matrix material separates from the composite material and flows through the porous element. The particulate volume fraction in the composite material gradually increases. When the particulate volume fraction exceeds about 37 volume percent, the mass of composite material becomes semi-solid and freestanding. The resulting composite material may be further processed, as by forming to a useful shape or diluting with another matrix material.

Filed: 2001-07-25
Abstract: Apparatus for monitoring one or more vital signs of a subject has a number of sensors. There is at least one redundant sensor. Each sensor originates a signal.      A selection system determines performance criteria for a number of groups of signals. Each group includes one or more signals. The apparatus computes a predicted value for a vital sign by either computing a value from each group of signals and taking a weighted average with weights based upon the performance criterion or by selecting one of the groups of signals for which the performance criterion is best and computing the output value from that group of signals. The output values are relatively insensitive to artifacts and to errors caused by the disconnection or malfunctioning of one sensor.
