  • Publication number: 20150085406
    Abstract: An electrostatic discharge clamp circuit is provided for low power applications. The clamp circuit includes: a detection circuit, a bias circuit and a shunting circuit having at least one shunt transistor. The detection circuit is configured to detect an occurrence of an electrostatic charge on a power supply node and trigger discharge of the electrostatic charge through the shunting circuit. The bias circuit is coupled between the detection circuit and the shunting circuit and applies a bias voltage to the gate terminal of the shunt transistor. During an electrostatic discharge event, the bias circuit is configured to generate a bias voltage that is substantially equal to the supply voltage; whereas, during the absence of an electrostatic discharge event, the bias circuit is configured to generate a bias voltage that is substantially half of the supply voltage.

  • Patent number: 8071105
    Abstract: The present disclosure relates to the discovery of methods of isolating subfractions of an F3 Reishi extract, and of administration of these novel isolates to eukaryotic cells in order to induce certain immumodulatory, hematopoeitic and tumor-inhibiting phenotypic changes in those eukaryotic cells, mediated through particular toll-like receptor (TLR) and other transmembrane receptors. F3 subfractions F301 and F331 have demonstrated that F331 is capable of activating at least TLR-2 while F301 is capable of activating at least TLR-2, TLR-4, and TLR-5.

  • Publication number: 20110253706
    Abstract: A heating device includes a first induction coil, a second induction coil, a first phase power unit, a second phase power unit, a power controller and a user interface unit. The second induction coil isn't always concentric with the first induction coil. The first phase power unit is connected with the first induction coil, and configured for receiving a first phase input voltage and outputting a first voltage. The second phase power unit is connected with the second induction coil, and configured for receiving a second phase input voltage and outputting a second voltage. There is a phase difference between the first phase input voltage and the second phase input voltage. The power controller is used for controlling operations of the first phase power unit and the second phase power unit. The user interface unit is connected with the power controller for controlling the power controller.

  • Patent number: 7894566
    Abstract: A shift register apparatus is provided. Each of shift registers within the shift register apparatus of the present invention is only constituted by a few of active and passive elements without using conventional digital logic elements, and even the passive element are not required at some conditions. Therefore, the layout area occupied/consumed by each of the shift registers of the present invention is relatively smaller than that of the conventional shift register constituted by a CMOS D-flip-flop, and thus a fabrication cost can be reduced.
