Title: Saturable bragg reflector
Inventor: KNOX WAYNE HARVEY
IPC: H01S5/00
Filed: 1996-02-19
Granted: 2001-11-06
Abstract: Low optical loss and simplified fabrication are achieved by a nonlinear reflector which incorporates one or more semiconductor quantum wells within a standard semiconductor quarter wave stack reflector. The nonlinear reflector provides an intensity dependent response which permits it to be used for saturable absorption directly in a main oscillating cavity of a laser. Saturation intensity of the nonlinear reflector and thereby related laser modelocking properties can be controlled by disposing the quantum well at a particular position in the reflector structure.

Title: Cloning and regulation of an endothelial cell protein c/activated protein c receptor
Inventor: FUKUDOME KENJI
IPC: A61K31/70
Filed: 1995-08-09
Granted: 2010-12-21
Abstract: Human protein C and activated protein C were shown to bind to endothelium specifically, selectively and saturably (Kd=30 nM, 7000 sites per cell) in a Ca2+, dependent fashion. Expression cloning revealed a 1.3 kb CDNA that coded for a novel type I transmembrane glycoprotein capable of binding protein C. This protein appears to be a member of the CD1/MHC superfamily. Like thrombomodulin, the receptor involved in protein C activation, the endothelial cell protein C  receptor (EPCR) function and message are both down regulated by exposure of endothelium to TNF. Identification of EPCR as a member of the CD1/MHC superfamily provides insights into the role of protein C in regulating the inflammatory response, and determination of methods for pharmaceutical use in manipulating the inflammatory response.

Title: Fluorescent optical sensor
Inventor: COLVIN ARTHUR E JR
IPC: G01N21/77
Filed: 1996-02-15
Granted: 2002-01-08
Abstract: A fluorescent sensor (10) for detecting the presence and amount of an analyte. The fluorescent sensor (10) has a photodetector (12), a high pass filter (14) located adjacent the photodetector (12), and a glass layer (80) located adjacent the high pass filter (14). An indicator layer (18) is located adjacent the glass layer (80) and a light emitting diode (20) is embedded in the indicator layer. The indicator layer has indicator molecules that provide a fluorescent emission as a result of light from the light emitting diode (20). The indicator layer (18) also allows an analyte to diffuse into it and the presence of the analyte reduces the amount of light emitted from the indicator molecules that passes through the glass layer (80) and the high pass filter (14) and is incident upon the photodetector (12). Since the amount of current from the photodetector (12) depends upon the incident light, this is used to detect the presence and amount of analyte. In one embodiment a waveguide is also present.

Abstract: A transformer core-coil frame attachment and ground. The core-coil is mounted on a metal frame with flanges extending along the bottom of the frame. Nonconductive support members in the form of channels are mounted on the flanges of the cross member to support the coil to relieve stresses and reduce the no-load electrical losses. The nonconductive support members have a profile shaped for ease in receiving and retaining the support members on the flanges of the cross member. The frame has an opening in the bottom for receiving a mounting boss protruding above the tank bottom of the transformer to locate the core-coil within the tank and resist movement of the core-coil within the tank in a horizontal plane. A compressible grounding structure is attached to the bottom of the core which allows for variation between the core and frame. Bracket structure is connected to the top of the frame and to brace structure secured to one of the sidewalls within the tank to limit movement of the core-coil in the vertical plane. This one point attachment keeps the unit from shifting during shipment.

Abstract: A process and system which improves the capacity and efficiency of a power plant. An LNG supply system (12) fuels the plant. Gasified LNG in a combustor (30) mixes with the air from an air compressor (28) to provide the hot combustion gas for a gas turbine (32). The expanding LNG is used to chill (16) a heat exchange fluid, e.g. water, which heat exchange fluid cools (24) and densifies the intake air for the air compressor (28). Subsequently, the heat exchange fluid is used in another heat exchange step (46) and is then re-chilled and recycled to cool and densify the intake air.

Title: Distributed resistance leadwire harness assembly for physiological monitoring during magnetic resonance imaging
Inventor: MEISTER MARK L
IPC: A61B5/0408
Filed: 1998-12-09
Granted: 2007-11-27
Abstract: A leadwire harness system is used for recording an electrocardiogram (ECG) during magnetic resonance imaging (MRI). The system includes a set of leadwires each having a nichrome wire helically wound on a bundle of glass or other high strength fibers and surrounded by an insulating jacket to provide for uniformly distributing the high resistance within each leadwire so that the eddy currents generated by the rapidly changing magnetic field are greatly reduced. The set of leadwires are twisted within a surrounding tube of foam insulation. The reduction of the eddy currents dramatically reduces MRI image distortion as well as the potential for localized heating and skin burns under the ECG electrodes used with the harness system.
