Patent CA-2177102-A1 (CA)
Inventor: PETERSON RUDOLPH ANTHONY JR
IPC: F02D17/04
Filed: 1996-05-22
Abstract: The pull-in coil of a fuel shut-off solenoid on an engine is connected to a thermistor circuit for limiting the current to the pull-in coil.  The pull-in coil is connected to ground through terminals of a control relay and through a thermistor. The activation coil of the control relay is also connected to the thermistor.  When power is initially supplied to the pull-in coil, the resistance of the thermistor is low and current flow is sufficient to activate the fuel shut-off solenoid. The initial low resistance also assures that the voltage at the control relay activation coil remains near ground so the control relay initially remains deactivated.  As the thermistor heats and resistance increases, pull-in coil current diminishes and voltage at the control relay increases until the control relay activates to interrupt power to the thermistor.  The thermistor cools so that upon occurrence of the next pull-in solenoid activation pulse, the solenoid pull-in coil will immediately activate.

Title: Traveling mat backing
Inventor: ERLAND JONATHAN
IPC: G03C5/06
Filed: 1996-10-10
Abstract: The present invention provides an improved backing screen having particular application for use in composite photography. In particular, the present invention relates to color difference composite photography, whether still, motion picture, video, solid state digital electronic or electrophotographic imaging, in which foreground and background scenes are separately recorded and subsequently combined using known "blue screen" or special color background techniques to form a single image. The present invention includes a biaxially stretchable fabric of synthetic fibers treated with a dye formulation, including fluorescence which is reactive to the visible spectrum, to achieve any of a variety of specific spectral loci and luminances, for the purpose of providing a precise chromatic actinic stimulus response for a silver halide photographic film, or similar response for electronic imaging devices. The selected backing is deployed in a support such that the fabric is stretched to a smooth, featureless surface and then illuminated. Foreground subject matter interposed between the camera and the backing or directly on the backing will therefore be readily distinguished and "matted" for compositing by methods well known to the art. In a further aspect of the present invention, the light emitting characteristics of the fluorescent matte fabric of the present invention may be advantageously relied upon to obtain the desired lighting effect in, for example, underwater photography. In yet another embodiment of the present invention, the matte fabric of the present invention may be configured to cover objects or parts of a person in a field of view.

Patent CA-2197757-A1 (CA)
Title: Synchronous multipoint-to-point cdma communication system
Inventor: GIALLORENZI THOMAS ROBERT
IPC: H04B1/7085
Filed: 1995-08-15
Abstract: A multipoint-to-point CDMA communication system comprises a plurality of CDMA  transmitting stations (TS1, TS2, TS3) and a single CDMA receiving station (RS), all of which are intercoupled to each other over one CDMA channel (FB1) and one feedback channel (FB2). On the one CDMA channel, the plurality of CDMA transmitting stations simultaneously send respective CDMA signals (21, 22, 23 of fig. 2) to the receiving station. In the receiving station, respective time differences are measured between a reference clock signal (RCK) and the spreading codes in the CDMA signals from each of the CDMA  transmitting stations; and these time differences are indicated in respective error signals (ER1, ER2 in 27 of fig. 2) which the CDMA  receiving station sends on the feedback channel to each of the CDMA transmitting stations. Each CDMA station responds to its error signals by time shifting its spreading code such that it arrives in the receiving station in synchronization (24, 25, 26 of fig. 2) with the reference clock signal. This synchronization enables interference between the spreading codes at the receiving station to be reduced by using codes which have minimal cross-correlation when their time difference is zero; and consequently, the maximum number of stations that can simultaneously transmit is increased.

Patent CA-2199678-A1 (CA)
Title: Monitor for uncommanded braking
Inventor: SALAMAT BIJAN
IPC: B60T17/22
Filed: 1997-03-11
Abstract: The monitor for uncommanded braking controls uncommanded brake application on one or more wheels during takeoff of an aircraft.  Brake pedal application is determined,  brake pressure is measured,  and brake pressure is compared with a selected threshold brake pressure.  A brake pressure applied signal is generated when the brake pressure  exceeds the threshold brake pressure.   The  pedal  application  signal  and  brake pressure applied signal are received by a fault latch logic circuit that generates a fault latch output signal when uncommanded braking has occurred.  A test inhibit signal is also generated when weight is not applied on the wheel.  The test inhibit signal is also input to the fault latch logic circuit so that uncommanded braking can occur when the aircraft is in the air and weight is off the wheel.   The monitor disables or latches off the shutoff valve when pressure is detected without pedal application.  A fail-safe feature re-enables the shutoff valve to allow it to turn on, and monitoring is stopped, when pedal application is detected.

Title: Envelope detector useful in crash discrimination
Inventor: GIOUTSOS TONY
IPC: B60R21/01
Filed: 1995-09-13
Abstract: A system (10) and method for detecting an envelope of received vehicle acceleration information (a(t)) useful in controlling actuation of a vehicle passenger safety device, wherein consecutive values for received vehicle acceleration information (a(t)) are stored and rank-ordered in a pair of rankorder filters (14, 16) to provide a highest-ranked value (aH) from among the most-recent half of the stored values, and a highest-ranked value (aH') from among the least-recent half of the stored values. The absolute value of the highest-ranked least-current value is taken and subtracted (24) from the highest-ranked most-recent value to obtain a modified jerk measure (jH*). The absolute value of the thus-generated modified jerk value is taken (26) to obtain a measure (m1) which tracks the envelope of the received acceleration information and, hence, is useful as an envelope detector when evaluating a crash waveform for purposes of controlling actuation of the safety device.

Patent CA-2202442-A1 (CA)
Inventor: HARRIS TIMOTHY A
IPC: F16C39/06
Filed: 1997-04-11
Abstract: Active magnetic bearings are used to suspend shafts of rotating equipment subject to load spectra which vary with respect to time. Control of the position of the rotating assemblies of such equipment is effected by electromechanical systems which combine the use of feedback control to switching amplifiers. The output of these amplifiers must vary of the order of thousands of cycles per second in order to maintain or adjust the desired position for the practical application of such systems in industrial rotating machinery. Furthermore, the application demands that only switching amplifiers be used for reasons of efficiency. The invention comprises a new scheme of switching such amplifiers to result in a more efficient use of power, resulting in less generation of resistance losses which manifests itself as heat. The new switching scheme results in lower operating temperatures which extend the life expectancy and improve the reliability, of magnetic bearing systems.

Abstract: According to the present invention, an oil storage chamber for temporarily accumulating a high-viscosity oil is formed below a heat-generating chamber for accumulating high-viscosity oil which generates heat when a shearing force is applied thereto.  When an electromagnetic coil of an electromagnetic clutch is set off, i.e., a rotation of a rotor of viscous heater is stopped, the high-viscosity oil in the heat-generating chamber moves into the oil storage chamber by own weight thereof, and a liquid level of the high-viscosity oil in the heat-generating chamber is greatly reduced.  In this way, when the electromagnetic coil of the electromagnetic clutch is turned on to start the rotor of the viscous heater, a torque applied to the rotor is greatly reduced, with the result that a stress applied to the rotor is reduced.
