  • Publication number: 20160055984
    Abstract: Polypyrrole/carbon (PPy/C) composite doped with organic anion p-toluenesulfonate (pTS) is utilized as an electrode in supercapacitor for energy storage application. The surface initiated in-situ chemical oxidative polymerization yields a composite material PPy/C in the presence of varying concentrations of pTS. The novelty of the present invention lies in the doping of PPy/C composite with organic anion pTS and consequent enhancement of its electrochemical activity and stability. The conjugation length and electrical conductivity of pTS doped PPy/C composites increase with the increase in dopant concentration. The pTS doped PPy/C composite synthesized using equimolar concentration (0.1 M) of pTS to pyrrole shows the maximum specific capacitance of ˜395 F/g in 0.5 M Na2SO4 aqueous solution with significant stability ˜95% capacitance retention after ˜500 cycles.

  • Patent number: 9177633
    Abstract: SRAM devices are disclosed that utilize write assist circuits to improve the logical transitions of bit lines. In one embodiment, an SRAM device includes a pair of complimentary bit lines traversing a memory cell array for writing data to memory cells. The bit lines have a first end and a second end. A pair of complimentary write drivers is proximate to the first end of the bit lines that writes to the bit lines. A write assist circuit is proximate to the second end of the bit lines that receives a pre-charge signal to assist the write drivers in transitioning the bit lines from a logical zero state to a logical one state. The write assist circuit also receives a boost signal to assist the write drivers in transitioning the bit lines from a logical one state to a logical zero state.

    Abstract: Word line decoders for dual rail SRAM devices are disclosed for high performance sub-micron SRAM designs. One embodiment is an SRAM device that includes a memory cell array and a word line traversing the memory cell array for selecting memory cells of the memory cell array. A row decode-driver coupled to the word line toggles the word line between logic levels of a memory cell supply based on select signals that toggle between logic levels of a peripheral supply. The row decoder-driver toggles the word line without utilizing level shifters along the word line access path.

  • Patent number: 9147495
    Abstract: A read-only memory (ROM) cell has first and second transistors connected in series between a true bit line and a voltage reference (e.g., ground), and third and fourth transistors connected in series between a complement bit line and the voltage reference. The gates of the first and third transistors are connected to a first word line, and the gates of the second and fourth transistors are connected to a second word line. The ROM cell is programmed to store any possible combination of two bits of information by appropriately (i) connecting the node between the first and second transistors to either the true bit line, the complement bit line, or the voltage reference and (ii) connecting the node between the third and fourth transistors to either the true bit line, the complement bit line, or the voltage reference.

  • Patent number: 9094433
    Abstract: Systems, methods, and devices for bearer independent protocol gateway performance optimization are described. In one aspect, a bearer independent protocol gateway is provided in the device which includes a traffic analyzer configured to detect when HTTP transaction(s) (request and corresponding responses) is/are completed and to switch to the next socket as soon as the transaction is completed, without necessarily waiting for the TCP socket to be closed. For example, when the gateway detects that the response is complete, it may push the current socket back into a socket queue and start serving the next socket.

  • Patent number: 9064583
    Abstract: A Read Only Memory (ROM) and method for providing a high operational speed with reduced leakage, no core cell standby leakage, and low power consumption. The source of the ROM cell (NMOS) is connected to a virtual ground line (VNGD) instead of VSS. Thus, the ROM cell can be operatively coupled to the bit-line, the word-line, and the virtual ground, which also acts as a column select signal. The arrangement of the ROM is such that the virtual ground of the selected column is pulled down to a ground voltage. Non-selected columns virtual ground can be maintained at a supply voltage to ensure that unwanted columns will not have any sub-threshold current (as Vds=0). Since no pre-charging of bit-line comes in the access time path, the ROM achieves a high operational speed with reduced leakage and low power consumption.

  • Publication number: 20150162750
    Abstract: Systems, methods, and devices relating to operating a power generation facility to contribute to the stability of the power transmission system. A controller operates on the power generation facility to modulate real power or reactive power or both in a decoupled manner to contribute to the stability of the power transmission system. Real power produced by the power generation facility can be increased or decreased between zero and the maximum real power available from the PV solar panels, as required by the power system. Reactive power from the power generation facility can be exchanged (injected or absorbed) and both increased or decreased as required by the power transmission system. For solar farms, the solar panels can be connected or disconnected, or operated at non-optimal power production to add or subtract real or reactive power to the power transmission system.
