Patent CA-2275176-A1 (CA)
Title: Common electrode voltage driving circuit for a liquid crystal display
Inventor: WOOD TEDDY J
IPC: G09G3/20
Filed: 1997-11-18
Abstract: A control circuit for providing a common electrode voltage for a liquid crystal display dynamically controls the voltage applied to the common electrode according to various factors that effect the capacitance across the liquid crystal layer. The common electrode control circuit dynamically adjusts the common electrode voltage according to the current maximum and minimum display voltages. In addition, the common electrode control circuit adjusts the common electrode:  voltage according to the gate-to-source parasitic capacitance, as well as temperature fluctuations. Thus, the control circuit compensates for the most significant factors which may cause the inadvertent accumulation of a charge across the liquid crystal layer.
Patent CA-2275655-A1 (CA)
Inventor: KAEB TODD
IPC: B65G15/40
Filed: 1999-06-16
Abstract: A conveyor belt that uses cleats to more effectively transfer materials through a curvilinear structure into a deposit receptacle. The cleats are either in the form of a notched cleat or slit cleat. In both forms, the cleat is adaptable to conforming from a flat conveyor belt to a curved conveyor belt within the curvilinear structure. The resulting cleat on the conveyor belt provides increased support for the prevention of backflow of materials during transportation of the material:; through the curvilinear structure.

Patent CA-2290096-A1 (CA)
Inventor: VIENOT MICHAEL E
IPC: E21B28/00
Filed: 1999-11-17
Abstract: This invention provides an apparatus and process for producing heavy crude oil from a subterranean formation penetrated by a well bore. In accordance with the process, an aqueous alkaline chemical solution is introduced into or formed in the well bore penetrating the formation. The aqueous alkaline chemical solution mixes and reacts with produced heavy crude oil in the well bore and ultrasonic waves are emitted into the mixture whereby an emulsion is formed. The viscosity of the formed emulsion is less than that of the crude oil or the crude oil and water mixture flowing into the well bore which allows the oil to be more efficiently pumped to the surface and transported for further processing.

IPC: G06F13/14
Filed: 2000-04-05
Abstract: Buffer management for improved PCI-X or PCI bridge performance. A system and method for managing transactions across a PCI-X or PCI bridge, and a system and method of waiting for, increasing, and/or optimizing the available buffers for transaction size or sizes across a PCI-X or PCI bridge. Transactions are processed across the bridge, and the bridge has buffers with actual available buffer space used for receiving and processing the transactions. Transaction size of the transaction is determined. The system and method sets an available free block which is a set amount of available buffer space that is to be freed up before certain larger size transactions are processed. The system and method waits for the actual available buffer space to free up to and reach the available free block. The certain larger size transactions are then processed when the actual available buffer space has reached the available free block. The processing of the transaction involves accepting the transaction if the transaction size is not greater than the actual available buffer space, retrying the transaction for processing by the bridge when the transaction size is less than the available free block but greater than the actual available buffer space, retrying the transaction by the bridge when the transaction size is greater than the available free block and greater than the available buffer space until the available buffer space is greater than or equal to the available free block, and accepting the transaction and then disconnecting once the actual available buffers are filled or at an end of the transaction.

Patent CA-2310957-A1 (CA)
Title: Optical device
Inventor: NAKANO YOSHIAKI
IPC: G02F1/35
Filed: 2000-06-07
Abstract: An optical device having a large extinction ratio and being suitable for the digital operation including first and second electrodes (7, 8) formed on both sides of a waveguide structure, respectively such that a carrier-injection region (3a) and a non-carrier injection regions (3b) are formed adjacent to each other in the waveguide structure. When mass carriers are stored in the carrier injection region, its refractive index is reduced lower than the non-carrier-injection regions. In this state, when a light wave with low optical power propagates through the carrier-injection region, since an amount of carriers consumed thereby is small, the refractive index of this region is still lower than the non-carrier-injection regions, and the input light wave is emitted sideways through the non-carrier-injection region. In contrast, when a light wave with high optical power propagates through the carrier-injection region, since the carrier consumption is large, the refractive index of this region (3a) becomes higher than the non-carrier-injection regions (3b), and the input light propagates through a waveguide which is optically induced to extend from the incident surface to the exit surface.

Title: Retractable wheelchair anchor
Inventor: CARDONA EDGARDO
IPC: B60P7/08
Filed: 2000-06-29
Abstract: A wheelchair anchor for use in a vehicle is movable between a retracted position in which it takes up a relatively small amount of floor space within the vehicle and an extended position in which it provides a plurality of anchor points to which one or more wheelchairs may be secured. An elongated track plate is secured to the floor of the vehicle so that it extends transversely to the direction of vehicle motion, and a beam assembly made up of three beams telescopingly engaged with one another is slidable along the track plate between a retracted position adjacent a first end of the track plate and an extended position wherein the beam is slid toward the opposite, second and the track plate. The distal end of the beam assembly is securable to the track plate adjacent the midportion of the track to maintain the beam assembly in the retracted position adjacent the first end of the track, and is alternatively securable to the track adjacent the second end to maintain the beam assembly in the extended position.     Mounting brackets are disposed on the different segments of the beam assembly so that when the beams are in the extended position the brackets are spaced from one another to allow wheelchair restraint straps to be connected to the brackets.

Title: Jitter frequency shifting .delta.-.sigma. modulated signal synchronization mapper
Inventor: OLIVER GORDON ROBERT
IPC: H03M7/36
Filed: 2000-08-21
Abstract: A signal synchronization mapper for mapping an input data stream characterized by a first frequency (typically a SONET/SDH stream) into an output data stream characterized by a second frequency. A phase lock control loop containing a "delta-sigma" (.DELTA.-.SIGMA.) modulator which functions as a voltage controller oscillator synchronizes the data rate of the output stream to that of the input stream in a manner which simplifies attenuation of fitter energy when the output data stream is desynchronized (demapped). The modulator generates an accurate pulse train by duty-cycle dithered modulation of the input stream, which the mapper interprets as stuff/null/de-stuff commands such that the mapping operation is lossless over time (i.e. the number of bits in equals the number of bits out over time) thus allowing utilization of a FIFO buffer without the need to monitor the buffer's depth or its pointers.
