Title: Window regulator having improved crank assembly
Inventor: SMITH PETER J
IPC: E05F11/50
Filed: 1998-05-06
Abstract: A window regulator assembly comprising a window panel (12), a track (18), a slider member (17), a slider moving assembly (21), including a drive assembly (20) and a coupling assembly (23). The coupling assembly (23) of the slider moving assembly (21) is constructed and arranged to couple an output movement of the drive assembly (20) to the slider member (17). The drive assembly (20) includes a drivable input structure (112) and a driven output structure (114), which structures are rotatable about a common axis. The drive assembly includes roller (128) and spring (130) members disposed within a housing (126) and constructed and arranged to prevent movement of the output structure (114) upon predetermined external force being applied thereto via the coupling assembly (23). The output structure (114) has ramp surfaces (149) each converging toward the housing (126). Each of the ramp surfaces (149) frictionally engages an associated one of the rollers (128), the rollers (128) being biased by the spring members (130) in a converging surface direction towards the converging surfaces between the ramp surfaces (149) and the housing (126). The wedging relation of the rollers (128) between the ramp surfaces (149) and the housing (126) prevents movement of the output structure (114) upon application of the predetermined external force being applied thereto. The input structure (112) is rotatable to engage the rollers (128) upon application of the external driving force and thereby move the rollers (128) against the bias of the spring members (130) and away from the converging surface direction, so that continued driven movement of the input structure (112) is received by the output structure (114) so that the output structure (114) is thereby driven to move the slider member (17) and thus the window panel (12) via the coupling assembly (23).

Title: Diagnostic assays using soluble endothelial cell protein c/activated protein c receptor
Inventor: ESMON CHARLES T
IPC: C07K14/74
Filed: 1998-06-26
Abstract: Plasma EPCR has been isolated, characterized and shown to block cellular protein C activation and APC anticoagulant activity. Plasma EPCR appears to be about 43,000 daltons and circulates at approximately 100 ng/ml (98.4 ~ 27.8 ng/ml, n = 22). Plasma EPCR bound activated protein C with an affinity similar to that of recombinant soluble EPCR (Kd app approximately 30 nM), and inhibits both protein C activation on an endothelial cell line and APC anticoagulant activity in a one-stage factor Xa clotting assay. Soluble plasma EPCR appears to attenuate the membrane-bound EPCR augmentation of protein C  activation and the anticoagulant function of activated protein C. Soluble EPCR has also been detected in urine. Levels of soluble EPCR can rise in inflammatory disease associated with vascular injury and appear to be correlated with inflammation and disease states associated with abnormal coagulation.

Title: Gas fired infrared radiant tube heating system using plural burner assemblies and single gas delivery system
Inventor: MURDOCH MARK
IPC: F24D5/08
Filed: 1998-06-17
Abstract: A gas fired infrared radiant heating system of improved thermal output. The present invention solves problems associated with prior art designs by providing a single gas delivery system for delivering combustible gas to two or more burner assemblies. The invention consists of a burner housing (10) with two or more burner assemblies (18), each of which can be connected to a typical radiant tube heat exchanger assembly (12). The homer housing contains a single gas delivery system including a valve (14), a single control circuit module (30), a single blower proving switch (50), and a single manifold (16) which will distribute the gas to the multiple radiant tube heat exchanger assemblies (12). In addition, in positive pressure configurations, the burner housing will also have a single air fan (38), whereas in negative pressure configurations of the heating system one or more exhaust fans may be utilized. The foregoing design will provide a higher thermal output without the heat distribution and installation cost problems of the currently available infrared heaters.

Inventor: TSIRONIS CHRISTOS
IPC: H01P1/20
Filed: 2000-06-14
Abstract: The present invention is an adaptable pre-matched tuner system and calibration method for measuring reflection factors above .GAMMA.=0.85 for a DUT. The system includes a first and second large-band microwave tuners connected in series, the first and second large-band tuners being mechanically and electronically integrated; and a controller for controlling the two large-band tuners. The first tuner is adapted to act as a pre-matching tuner and the second tuner is adapted to investigate an area of a Smith Chart that is difficult to characterise with a single tuner, so that the combination of the first and second large-band tuners permits the measurement of reflection factors above .GAMMA.=0.85. The pre-matched tuner system allows the generation of a very high reflection factor at any point of the reflection factor plane (Smith Chart). The pre-matched tuner must be properly calibrated, such as to be able to concentrate the search for optimum performance of the DUT in the exact location of the reflection factor plane where the DUT performs best, using a pre-search algorithm.

Title: Clock stretcher and level shifter with small component count and low power consumption
Inventor: MILIOS IOANNIS
IPC: G06F1/08
Filed: 1998-07-09
Abstract: A clock stretching circuit (110) mediates between a synchronous bus (112) and a microcontroller (124) which is asleep most of the time to save electrical power. The bus is of a type in which a slow bus device can cause the sender of data to "hold" the data until the slow device is up to speed. The stretching circuit (110) is of small component count and low power consumption, and there is no requirement for a continuous clock. In one embodiment is comprised of a triple analog switch (120, 121, 122) and a very small number of additional components. In another embodiment a dual four-position multiplexer (162, 163) is employed. In still another embodiment, four transistors (210, 212, 213, 215) are used with handful of additional components. A level shifter (220, 221, 222, 223) including an MOSFET and a large-value resistor help to minimize power drain within the bus device. The components can be external to an off-the-shelf microcontroller or can be included in an IC that also contains an embedded microcontroller.
