    • A static random access memory ("SRAM") that is especially suitable for such uses as inclusion on a programmable logic device to provide programmable control of the configuration of that device. The SRAM includes a plurality of SRAM cells, all of which are simultaneously cleared to a first of two logic states by application of a second of the two logic states to clear terminals of the cells. Any cell that needs to be programmed to the second of the two logic states is thereafter specifically addressed and a data signal thereby applied which programs the cell to the second logic state. The cells are preferably constructed so that they are programmed to the second logic state by application of a data signal having the first logic state. Even a very small unipolar MOS pass gate transistor can therefore be used as the addressable path through which the data signal is applied. The memory may also include circuitry for verifying the contents of each cell via the data input terminal of the cell.

    • An apparatus for location identification using broadcast wireless signal signatures includes a receiver to receive first measurements of a plurality of wireless television signals. The first measurements are made by a remote device receiving the plurality of wireless television signals. In addition, the apparatus includes a processor to select one or more of a plurality of possible locations of the remote device based on the first measurements and a plurality of associations each associating one of the possible locations with expected values. Moreover, the receiver receives second measurements of the wireless television signals made by one or more monitor units, and the processor generates the expected values for the first measurements and the associations based on the second measurements and the locations of the one or more monitor units.
    • 用于使用广播无线信号签名的位置识别的装置包括接收多个无线电视信号的第一测量的接收机。 第一测量由接收多个无线电视信号的远程设备进行。 另外,该设备包括处理器,用于基于第一测量值选择远程设备的多个可能位置中的一个或多个,以及多个关联,每个关联将每个可能位置之一与期望值相关联。 此外,接收机接收由一个或多个监视器单元产生的无线电视信号的第二测量,并且处理器基于第二测量和一个或多个监视器单元的位置,产生用于第一测量和关联的期望值。

    • A logic element includes memory elements, multiplexers, and controls. The multiplexers are arranged in levels including a highest level of multiplexers with inputs connected to the memory elements and outputs connected to inputs of a next-to-highest level of multiplexers and a first level of multiplexers with inputs connected to outputs of a second level of multiplexers and at least one output. The controls are connected to the multiplexers. In a first operational mode the controls determine a first-mode output at the at least one output of the first level of multiplexers, and in a second operational mode the controls determine a plurality of second-mode outputs at selected outputs of multiplexers not at the first level of multiplexers.
