  • Patent number: 9270327
    Abstract: A method and apparatus used to transmit and receive weighted data transmissions over a plurality of antennas using a plurality of different pilot signals. Different pilot signals are produced and a different pilot signal of the plurality of pilot signals is transmitted on each of a plurality of antennas. Each of the pilot signals is derived from a pseudo noise (PN) sequence and a bit sequence of the PN sequence for each of the pilot signals is different. A plurality of data streams are produced in which each of the data streams has data bits combined with bits of a PN sequence. The data streams are weighted in response to weight information received from a receiving device and the plurality of weighted data streams are transmitted using the plurality of antennas.

  • Patent number: 9155132
    Abstract: A microwave container includes a container body and a lid. The container body has a bottom wall, a sidewall extending upwardly from a periphery of the bottom wall and ending at a rim. The lid has a top wall, a sidewall extending downwardly from a periphery of the top wall and ending at a brim. The lid is formed with a vent opening. The flap includes a proximal portion hingedly connected to the brim of the lid by a living hinge and an outwardly extending distal portion formed with a plug, wherein the flap is movable between a free-hanging position where the flap is hanging freely from the brim of the lid and a closed position where the flap is flipped about the hinge over a side of the lid and the plug is plugged into the vent opening.

  • Patent number: 9036680
    Abstract: A code division multiple access communication system transmits a pilot and traffic signal over a shared spectrum. The pilot and traffic signal have an associated code and are received over the shared spectrum. The received signals are sampled and the samples are delayed to produce a window. A weighted value for each despread pilot code window sample is determined using an adaptive algorithm. Each window sample is despread with a traffic code. Each despread traffic code window sample is weighted according to a weight corresponding to its respective pilot code sample.

  • Patent number: 6278726
    Abstract: A transmitter transmits a spread spectrum pilot and data signal. Each signal has an associated chip code. A receiver receives the transmitted pilot and data signal. The received pilot signal is filtered using the pilot chip code and weights are determined for components of the received pilot signal using an adaptive algorithm. The received data signal is weighted by the determined weights and filtered with the data signal chip code to recover data from the received data signal.

  • Patent number: 5773855
    Abstract: Field-effect transistors are formed on a substrate having silicided elements including diffusion (source and drain) regions and polysilicon gates. The silicided surfaces of these elements have low ohmic resistance and are used to provide interconnection between contacts that are spaced from each other, thereby freeing routing areas for other interconnections. The diffusion regions of adjacent transistors have edges that face each other, and are formed with indentations which constitute portions of a substrate tap area. The low ohmic resistance of the silicided surfaces of the diffusion regions enables the substrate tap area to be cut out of the diffusion regions without degrading the electrical performance of the transistors, thereby providing a substantial reduction in the space required for the transistors on the substrate.
