Inventor: GRAY JOHN
IPC: B60R21/205
Filed: 1996-04-10
Abstract: An air bag door arrangement is incorporated in an instrument panel that has a substrate and an uninterrupted covering for the substrate. The substrate includes an air bag opening that is closed by a door. The door has a hinged end that is clamped to the substrate by a frame that is beneath the substrate, a reinforcement bar that is above the substrate and a plurality of fasteners that force the frame and reinforcement bar toward each other. An air bag canister is attached to the frame beneath the air bag opening of the substrate and the frame is attached to automotive body structure so that the substrate is isolated from the reaction forces of the canister when an air bag housed in the canister inflates and pushes the door through the instrument panel covering.

Abstract: A test sample card has a fluid passage network provided on both sides of the card to provide for maximum separation distance between adjacent growth wells. The card also has cored sections along its periphery adjacent the wells, which improve the flow of plastic during the molding of the cards. The cored sections control the formation of knit lines in the surface of the card and eliminate knit lines from forming that could potentially bridge adjacent wells. These features, singly and together, combine to produce a card that is essentially immune to cross-talk between adjacent wells, yet permit a greater number of wells in a card of given dimensions. Improved bubble trap features are also provided for the card, including a bubble trap passage having a restriction formed therein. The restriction prevents air bubbles in the bubble trap from migrating back to the growth wells.

Title: Machined shaft seal encased in an elastomeric sleeve
Inventor: LAFLIN WILLIAM Q
IPC: F16J15/32
Filed: 1994-11-30
Abstract: A manually assembled shaft seal assembly includes plastic sealing element having an annular tubular mounting portion and a shaft-engaging sealing lip. An annular elas-tomeric sleeve extends around the inner and outer surfaces of the tubular mounting portion to provide a resilient mount-ing mechanism for the shaft seal assembly. During service at high operating temperatures the elastomeric sleeve ab-sorbs and accommodates stresses generated m the plastic tubular portion of the sealing element by thermal expansion The elastomeric sleeve is in a compressed condition when mounted within a shaft seal housing so that it can expand slightly if necessary, to compensate for shrinkage or creep in the plastic material, such that the seal assembly is pre-vented from becoming loose in the shaft seal housing.

Patent CA-2178664-A1 (CA)
Inventor: KAUFMANN JOHN
IPC: H03H17/06
Filed: 1996-06-10
Abstract: A signal conditioner comprising several embodiments of transversal (FIR) filters that utilize symbol addressed multiplier lookup tables. In particular, five embodiments in accordance with the principles of the present invention are described. The present invention generates a predistorted waveform within the transversal filter that provides for compensation for the effects of nonlinear amplifiers and intersymbol interference. The present invention may be employed to digitally generate an arbitrary baseband waveform that represents a limited alphabet of symbols. The present invention dramatically simplifies the implementation of FIR filters where the application of the FIR filter is to provide a transversal filter function for waveforms that represent symbols. The degree of simplification is related to the number of bits that define the size of the symbol alphabet as compared to the number of bits required to adequately represent a digital sample of the waveform. Typically 2, 3, or 4 bits represent the alphabet of communication symbols, whereas waveforms require as a minimum 8 bitsof quantization.  A second aspect of the present invention comprises combining the function of generating arbitrary waveforms with the symbol addressed lookup tables that are part of the FIR filter. The waveform is precompensated to minimize the effect of intersymbol interference and is prewarped to compensate for transmitter nonlinearities.

Title: Multi-beam tdma satellite mobile communications system
Inventor: HART NICHOLAS
IPC: H04B7/185
Filed: 1995-05-16
Abstract: An earth station (8) receives a return signal,(3) via more than one satellite link (4a, 4b) from a mobile terminal (2) using TDMA. The earth station (8) selects one or more of the satellite links (4a) for transmitting a forward signal (15) on the basis of the quality of signal (3; 15) received via each link. The earth section (8) allocates frequency channels to the mobile terminals (2) according to their location on the surface of the earth, so that the propagation time to and from those mobile terminals (2) which share the same frequency channel is approximately the same. The satellite (4a; 4b) includes an antenna which generates an array of beams which are individually pointed to fixed regions of the earth, until the elevation of the satellite (4a; 4b) relative to a fixed region falls below a minimum value, in which case the corresponding beam is redirected to a new area, while the other beams remain pointed at the corresponding fixed areas. In this way, beam-to-beam handover is reduced, while maintaining the boresight of the antenna pointing at the nadir.
