  • Publication number: 20020059152
    Abstract: A neural processing module is disclosed which combines a weighted synapse array that performs “primitive arithmetic” (products and sums) in parallel with a weight change architecture and a data input architecture that collectively maximize the use of the weighted synapse array by providing it with signal permutations as frequently as possible. The neural processing module may be used independently, or in combination with other modules in a planar or stacked arrangement.
    Type: Application

  • Patent number: 5955668
    Abstract: A micro-gyro device is disclosed combining an element which oscillates around the drive axis and an element which rocks around the output axis, so arranged that Coriolis force is transmitted from one element of the other without any substantial transfer of motion of either element to the other in its own direction of motion. In other words, the masses of the two elements operate independently of one another, providing improved performance, and individual adjustability to compensate for any manufacturing imprecision. The presently-preferred device combines an outer ring which oscillates around the drive axis with an inner disk which rocks around the output axis, whenever external rotating motion occurs about the rate axis.

  • Patent number: 5635705
    Abstract: Circuitry for sensing a relatively large number of events, and outputting to processing circuitry only those events which have two characteristics: (1) a magnitude above a preselected threshold level, and (2) a rate of change greater than a preselected background rate of change. Logic circuitry is used to assign any event which has the desired characteristics to an available output channel. Subtracter circuitry causes the background to be subtracted from the sensing input, in order to limit the output to non-background events.

  • Patent number: 5581498
    Abstract: An electronic package is disclosed in which a plurality of stacked "same function" IC chips are designed to be used in lieu of a single IC chip, and to fit into a host computer system, in such a way that the system is "unaware" that substitution has been made. Memory packages are of primary interest, but other packages are also feasible, such as packages of FPGA chips. In order to "translate" signals between the host system and the stacked IC chips, it is necessary to include suitable interface circuitry between the host system and the stacked chips. Specific examples are disclosed of a 4 MEG SRAM package containing 4 stacked IC chips each supplying a 1 MEG memory, and of 64 MEG DRAM packages containing 4 stacked IC chips each supplying a 16 MEG memory. The interface circuitry can be provided by a single special purpose IC chip included in the stack, referred to as a VIC chip, which chip provides both buffering and decoding circuitry. Additionally, the VIC chip should provide power supply buffering.

  • Patent number: 5508836
    Abstract: A wireless infrared pulse-transmitting system for communication with electronic components. The receiver for such a system has radically reduced current (and power) values, which permit a battery-powered receiver to remain on while awaiting transmitter signals. Use of several mosfet transistors operating in the subthreshold region minimizes power. Bandwidth requirements are met, in spite of the low power operation. In order to eliminate amplifier saturation, with the accompanying problem of recovery time which slows the transmission process, clamping circuitry is used to cause instantaneous shunting of signals when a predetermined signal level is reached.
