  • Patent number: 7754059
    Abstract: A biosensor for determining the concentration of an analyte in a biological sample. The biosensor comprises a support, a reference electrode or a counter electrode or both disposed on the support, a working electrode disposed on the support, the working electrode spaced apart from the other electrode or electrodes on the support, a covering layer defining a sample chamber over the electrodes, an aperture in the covering layer for receiving a sample, and at least one layer of mesh in the sample chamber between the covering layer and the electrodes. The at least one layer of mesh has coated thereon a silicone surfactant. Certain silicone surfactants are as effective as fluorinated surfactants with respect to performance of biosensors. These surfactants, when coated onto the mesh layer of the biosensor, are effective in facilitating the transport of aqueous test samples, such as blood, in the sample chamber.

  • Publication number: 20100141632
    Abstract: A liquid crystal display includes a liquid crystal panel switchable between normal mode for displaying images and standby mode, a control circuit coupled to the liquid crystal panel controlling the liquid crystal panel mode according to video signals transmitted thereto, and a power board providing a power voltage to the control circuit. When the liquid crystal panel is in a standby mode, the control circuit outputs a corresponding feedback signal to interrupt power voltage supply from the power board to the control circuit.

  • Publication number: 20100008309
    Abstract: A method and system for establishing high-speed downlink shared channel, wherein the method comprises the following steps: RNC indicates Node B to establish high-speed downlink shared channel between the Node B and terminal; in response to the indication of the RNC, the Node B establishes high-speed downlink shared channel between the Node B and the terminal by using the preset high-speed downlink shared channel physical layer category; the terminal establishes radio resource control connection between the terminal and the RNC and returns information on the actual high-speed downlink shared channel physical layer category of the terminal to the RNC; and the RNC judges whether the actual high-speed downlink shared channel physical layer category of the terminal is identical with the preset high-speed downlink shared channel physical layer category, and if not, the RNC indicates the Node B to reestablish high-speed downlink shared channel between the Node B and the terminal by using the actual high-speed downli

  • Publication number: 20100002645
    Abstract: A method of flow control between radio network controller and base station is disclosed. The method includes: step 1, the base station carrying information of Maximum PDU Length in a capacity allocation frame of High Speed Downlink Shared Channel; step 2, the radio network controller receiving the capacity allocation frame from the base station; step 3, the radio network controller transmitting data to the base station, wherein the amount of data transmitted during one HS-DSCH Interval is less than or equal to the product of Maximum PDU Length carried in said capacity allocation frame and the maximum number of PDUs that can be transmitted during one HS-DSCH Interval. The disclosed method enables the base station control the flow with the radio network controller in the common state of the fortified connection mode.

  • Publication number: 20090009153
    Abstract: A multiple output AC/DC power adapter is provided. The adapter includes an adapter body with an output connector and more than one output plugs configured for connecting with the output connector. The adapter body includes a DC-DC converting circuit having an input terminal, an output terminal, a first adjustment terminal. The output connector includes a positive terminal, a second adjustment terminal and a negative terminal configured for connecting to the output terminal and the first adjustment terminal of the DC-DC converting circuit and ground correspondingly. The output plugs each includes an adjustment resistor having a resistance value different from the other output plugs. Therefore, when equipped with a plurality of output plugs each of the plurality of plugs having different resistor R0, the adapter can supply different output DC voltages for different electronic device.
