Abstract: A device for sensing the input shaft speed of an automotive automatic transmission that is driven by the engine through the fluid coupling of a torque converter. The speed sensor device includes circumferentially spaced markings about the transmission input shaft and a speed sensor that is placed at close proximity to the circumferentially spaced markings through a hole in the torque converter stator shaft. An electronic control unit (ECU) analyzes the sensor output signal and in the case of an active speed sensor it also functions as its power source. During vehicle operation, the transmission input shaft rotates the target wheel in front of the speed sensor causing modulation of its output signal. The electronic control unit analyzes the signal modulation and calculates the input shaft rotational speed. A variety of sensor/target-wheel options and sensor mounting techniques could be used depending on the application constraints.

Abstract: A display interface device and method for an individual personal computer, workstation, or embedded system comprising one or more display interfaces; a video library; and driving any one of a plurality of video displays of a plurality of types connected to the one or more display interfaces from output of the video library. OpenGL is a preferred API. Driving of hybrid displays as well as stroke displays using formats designed for raster displays (such as VAPS) is also provided for. Real-time switching between displays is also provided for.

Abstract: An auditory device is disclosed. The auditory device includes a behind-the-ear element and an at least partially in-ear element. The behind-the-ear element has a shell shaped to fit behind an outer portion of an ear of a user. The shell has first and second sides that are substantially parallel to each other. The first side faces the outer portion of the ear, and the second side faces a head of the user. The behind-the-ear element also includes sound processing circuitry within the shell. The behind-the-ear element further includes an ear cushion switch operatively connected to the sound processing circuitry. The ear cushion switch is located on the first side of the shell. The at least partially in-ear element includes a microphone, acoustic pickup pillow-pad, sensors, receiver and a cushioned tip. The at least partially in-ear element can include a closed ear detachable cushioned tip and an open ear detachable cushioned tip.

Abstract: A method for using an algorithm for autonomous, real-time computation of the inserted delays between successive calligraphic or stroke type vectors that optimizes both image quality and performance for systems that generate stroke video for cathode ray tube (CRT) type displays. The algorithm operates on parameters for vector angular change screen position, and stroke write rate or clock rate to determine an inner-vector delay and to optimize the image quality of the resulting vector graphics display. The algorithm can be implemented at a rudimentary level of the system level architecture and eliminates much of the tedious, manual effort associated with image quality optimization typically dictated by a vector display system.

Abstract: This invention provides fault tolerant capability for a Versa Module Eurocards backplane system design for high reliability applications. An approach of connecting two independent backplanes together electrically, but providing isolation capabilities in the event of a failure was developed. The electrical connection or integrated bridge design provides a virtual connection between the two VME backplanes that is transparent to the end user. The integrated virtual VMEbus design provides a low latency, high bandwidth interconnect between modules whether located on the same local bus or the electrically isolateable bus. This dual-VME fault tolerant backplane design eliminates complete system failures due to single event failures.
