Granted: 1999-12-07
Abstract: A torque limiter control sets the limit of power which may be absorbed by a pump. A feedback system adjusts the displacement in the pump in response to changes in the pressure of working fluid at the pump outlet to maintain a set power. A torque limiter set adjustment applies a torque setting force to a vent spool to bias the vent spool against a vent port to thereby seal the port. As working pressure fluid increases, the force of the fluid acting on the vent sleeve ultimately overcomes the setting of the torque limiter and commences to pull which in turn permits fluid to flow through a compensator metering spool to thereby change the displacement of the pump.

Patent CA-2179817-C (CA)
Inventor: BIRCHENOUGH CHARLES W
IPC: B60W30/18
Filed: 1995-11-17
Granted: 2006-11-14
Abstract: A control system (30) is provided for vehicle regulating engine speed during shifts so as to reduce driveline torque and shift shock. The control system (30) in- cludes separate microprocessor based en- gine and transmission controllers (32, 34) which communicate via a data link (36). When a shift is initiated the transmission controller (34) delays a first period of time CTSDELAY sufficient for the transmission (14) to disengage the old gear ratio and then produces a CTSSPEED signal. The transmission controller (34) continues to produce the CTSSPEED signal for a sec- ond period of time CTSDUR which corre- sponds to the time required for the trans- mission (14) to engage the new gear ra- tio. The control system (30) preferably includes means for sensing a lockup time period corresponding to the time required for the transmission (14) to lock up in the new gear ratio. The control system (30) is capable of modifying the second time pe- riod CTSDUR as a function of the sensed lockup time period.

Abstract: An imaging device comprises a semiconductor substrate (16) including an array of pixel cells.  Each pixel cell comprising an individually addressable pixel circuit (18) for accumulating charge resulting from radiation incident on a pixel detector.  The pixel circuit and the pixel detector can either be implemented on a single substrate or on two substrates bonded together.  The charge storage device can be a transistor, for example one of a pair of FETs connected as a cascade amplification stage.  An imaging plane can be made up of one imaging device or a plurality of imaging devices tiled to form a mosaic.  The imaging devices may be configured as a slot for certain applications, the slit or slot being scanned over the imaging plane.  Control electronics (24) can include addressing logic for addressing individual pixel circuits for reading accumulated charge from the pixel circuits.  Imaging optimisation can be achieved by determining maximum and minimum charge values for pixels for display, assigning extreme grey scale or colour values to the maximum and minimum charge values and allocating grey scale or colour values to an individual pixel according to a sliding scale between the extreme values. Scattered radiation can be detected and discarded by comparing the detected pixel value to a threshold value related to a minimum detected charge value expected for directly incident radiation and discarding detected pixel values less than said threshold value.

Abstract: Representative vectors z1i and z2j are selected from codebooks CB1 and CB1, respetively, and multiplied by weighting coefficient vectors w1 and w2 of the same number of dimensions as those of the representative vectors by multipliers 21 and 22, whereby weighted representative vectors z1iw1 and z2jw2 are generated. These weighted representative vectors are vector combined by a combining part 3 into a combined vector y ij, and a combination of the representative vectors is selected by a control part in such a manner as to minimize the distance between the combined vector y ij and an input vector X. The weighting coefficient vectors w1 and w2 each have a maximum component in a different dimension and are selected so that the sum of diagonal matrixes W1 and W2 using components of the weighting coefficient vectors as their diagonal elements becomes a constant multiple of the unit matrix.

Abstract: An apparatus and method is provided for modulating and transmitting full-motion, television quality color video signals along with digital data signals over a pair of ordinary unshielded twisted pair telephone wires (UTP) without interfering with normal telephone data on the wires. The invention is characterized by a transmission method involving frequency modulation (VCO1) of a baseband video signal and subsequent filtering (BPF1) to suppress an upper sideband corresponding to a color component of the original signal. The filtered signal is received from the telephone wires at a different location, filtered, demodulated and provided to a display device. Full-duplex modulation over the same pair of wires is possible, such that two video signals may be simultaneously transmitted, each signal having an approximate bandwidth of 6 MHz and shifted to a desirable non-interfering frequency location within the approximately 20 MHz of useable bandwidth on the telephone wires. No pre-emphasis or de-emphasis is required to achieve good quality video transmission.

Abstract: A program input may be translated into any of various graphics or television formats, and stored as compressed images, using any of several commercially available methods. While being processed, the images (e.g. 180) may be re-sized (182, 184) to produce a desired aspect ratio or dimensions using conventional techniques, such as interpolation, and signals within the video data stream optionally may be used to control "pan-scan" operations at a receiving end, in case this end does not have the same aspect ratio as the source signal. Frame rate conversion to and from conventional formats is performed by using the techniques employed for welt known film-to-NTSC and film-to-PAL transfers, or by inter-frame interpolation. By judicious selection of the optimal digitizing parameters, the system allows a user to establish an inter-related family of aspect ratios, resolutions, and frame rates, and yet remain compatible with currently available and planned formats.

Abstract: A system and corresponding method for enhancing hygiene in a food handling environment include an indicator to be worn by a worker in the food handling area, an activating device located outside of the food handling area, a hand cleaning station located proximate or within the food handling area (remote from the restroom), and a deactivating device operatively associated with the hand cleaning station. Upon leaving the food handling area, the indicator worn by the worker is activated when the worker enters a predetermined area proximate the activating device. Thereafter, the indicator is deactivated by the deactivating device only when it is determined that the worker has utilized the hand cleaning station proximate the food handling area. In such a manner, the prior art problem of worker contamination occurring between, for example, the restroom and food handling area is substantially eliminated. According to alternative-embodiments, the system and method may be used in hospital environments so as to prevent germs from spreading from one patient to another by way of medical personnel.
