  • Publication number: 20050027777
    Abstract: A high speed low powered 4-2 compressor according to the present invention performs an XOR/XNOR operation of input data by using a single input type NAND/NOR logic circuit and a dual input type NAND/NOR logic circuit. Thus, delays to generate complementary signals are avoided. In addition, the 4-2 compressor uses a single railed multiplexer instead of a dual railed multiplexer, so that gate drive nodes and internal load capacitance are reduced. As a result, circuit area and power consumption of the 4-2 compressor are reduced.

  • Patent number: 6717831
    Abstract: A content addressable memory (CAM) device providing higher integration density, high operation speed and low power consumption. The CAM device comprises a memory cell connected between first and second nodes, first and second data lines for transmitting first and second data signals to the first and second nodes, respectively, and first and second switching devices serially connected between a match line and a reference voltage, wherein the first switching device is controlled by the first data signal and a voltage of the first node and the second switching device is controlled by the second data signal and a voltage of the second node.

  • Patent number: 6668833
    Abstract: A birthing aid comprised of a rectangularly shaped compliant band dimensioned to be wrapped around the shin or thigh of a patient who is engaged in the birthing process. A compliant handle is attached to the outer surface of the band and positioned so that when a birthing aid is mounted on each leg, the patient may comfortably grasp the handles. A fastening system such as Velcro® is attached to each surface of the band in order fix each mounted band in place. Alternatively, the bands may be held in place by a quick-drying adhesive or instant glue. Other embodiments include a tapered cylinder, a series of loops, and a boot. These are all comprised of a compliant material. All have handles. The patient uses the handles to draw her legs toward her, thus assuming the preferred drawn-up legs position.
