Filed: 1993-04-06
Abstract: Apparatus for controlling the electrical functions in a plurality of different locations of a vehicle comprises a plurality of electrical control units connected to a data bus (23) and distributed throughout the vehicle. All control units are identical and all are programmed to carry out all the electrical functions of the vehicle. Each unit incorporates means to detect the resistance at the point at which it is connected into the circuitry and to compare that resistance with the stored table of resistance and to select on the basis of that comparison the program for operation appropriate to the particular location in which the unit is disposed. In this way only one unit needs to be certified and units may be switched from location to location to provide a "get you home" service should one of the units fail in a particularly critical location.

Title: Error variance processing equipment for display device
Inventor: ONODERA JUNICHI
IPC: G09G3/28
Filed: 1995-10-05
Abstract: Coupled to an error variance circuit 11 is an emission luminance characteristic acquisition circuit 20 that counts up, at a display number counter 21, the display number in the single or plural frames of the respective bits of image data by the counters, M in number, corresponding to said bits, then solves for display area percentage (Sk) dividing, at a display area percentage operation part 22, the display dot number as counted at a display number counter 21, by total dot number, and acquires the luminance deviation characteristic for each bit by means of an emission luminance deviation characteristic measuring part 24. The luminance deviation thus obtained is renewed for each frame and transferred to the error variance circuit 11, and processed for error variance on the basis of the emission luminance characteristic to be output at PDP. At low level, on the other hand, the luminance deviation is rendered either fixed type luminance deviation or emission luminance level more or less higher than the actual one to reduce the diffusion noise particularly at the low level image portion thereby obtaining a more natural image.

Patent CA-2163303-A1 (CA)
Inventor: SARINGER JOHN H
IPC: A61H1/02
Filed: 1995-11-20
Abstract: The present invention provides continuous passive motion (CPM) devices for joints. An ankle CPM device includes a lower leg support attached at its lower end to a semi-circular track. An actuator slides along the track and can be locked in any desired position on the track. A shaft is pivotally connected at one end thereof to the actuator and a shoe is attached at the other end thereof. When the actuator is positioned at the bottom of the track the ankle joint of the patient undergoes inversion/eversion motion. When the motor housing is rotated 90° and positioned near the top of the track plantar/dorsi flexion movement is obtained. A combination of both types of joint movement are obtained for the actuator in intermediate positions. A wrist CPM device includes a brace for the forearm attached to a semi-circular track on which an actuator is mounted. A hand grip is mounted on a semi-circular bracket and a shaft extends between the actuator and a coupling slidably mounted on the semi-circular bracket. With the actuator positioned below the forearm, when the actuator pivots the shaft the wrist joint undergoes ulnar/radial deviation movement and when the motor is rotated 90° and positioned at the side of the arm extension/flexion movement of the wrist joint is obtained. Positioning the actuator in intermediate positions produces wrist movement which is a combination of extension/flexion and ulnar/radial deviation of the wrist joint.

Title: Pacemaker telemetry system
Inventor: RYAN TERRENCE G
IPC: A61N1/372
Filed: 1994-05-10
Abstract: An implantable medical device telemetry system provides a means for decoding telemetry downlink information transmitted from an external unit to an implanted medical device, and for encoding telemetry uplink signals to be transmitted from the implanted device to the external unit. A novel system architecture results in a very small telemetry subsystem in the implanted device and a very flexible system adaptable to be used in conjunction with various telemetry formats of various implanted devices. A programmable logic array (PLA) structure that is mask programmable and which may further be partially RAM programmable serves as the basis of the telemetry subsystem For downlink telemetry, a counter is enabled during intevals of interest in the downlink RF burst stream. The counter value at the end of such an interval is then applied to the variable inputs of the PLA for decoding in accordance with a selected telemetry protocol. For uplink telemetry, the counter and PLA is used to control transmission of uplink telemetry pulses, such that pulses are pulse-position modulated in accordance with data to be transmitted. Various different telemetry protocols may be supported by the same telemetry circuit, which may be mask-masked at the time of manufacture to be compatible with one or more different telemetry protocols.

Abstract: A curved track support is disclosed for a door, window, access door and the like which includes a curved track carrier having a curved track and a trunnion carrier having a trunnion for engaging the first track.  Furthermore, the curved track carrier is provided with a second trunnion and the trunnion carrier is provided with a second curved track.

The mutually opposite placement of the trunnions and guide tracks stabilizes the curved track support and allows it to handle higher loads.  At the same time, a defined rotation/sliding movement of the door is achieved by controlled displacement of the axis of rotation.  Moreover, an exactly defined jam-free positioning of the door is achieved with substantially no play at any opening angle.  The respectively opposite positioning of the trunnions and the curved tracks results in a positive guiding operation and provides for a large range of trunnion paths with respectively different geometry so that substantially any desired rotation/sliding movement of the door can be achieved by appropriately designing the curved tracks.

Abstract: A calibrating pickup circuit detects, using primary and secondary pickups, the primary and secondary voltages of an ignition coil of known turns ratio.   The pickup circuit includes a programmable gain amplifier,  responsive to the detected secondary voltage waveform signal and to a gain control feedback signal for generating an amplified secondary voltage waveform signal wherein the feedback signal has an initial predetermined value in calibration mode and has a calibration  value  in  signal  monitor  mode.

Waveform comparison  is  then  performed  by  evaluating  the  single interlaced waveform signal and a secondary-to-primary ratio calculated representative of the signal strength difference between analogous portions of the primary and the amplified voltage  waveform  signals    A  calibration  value  is  then determined on the basis of the secondary-to-primary ratio and the known turns ratio of the ignition coil.
