  • Patent number: 8762822
    Abstract: Techniques are provided for decoding tail-biting convolutional codes by using information within the received data stream that traditionally has not been used or been available to the convolutional decoder, e.g., cyclic redundancy check (CRC) and bit information known by both the transmitter and receiver. Further, a single parallel trace-back is used that reduces implementation complexity. In addition, the least reliable decisions made during forward processing may be reversed in order to generate additional possible codeword candidates. These techniques can be used to reduce false detection rates (FDRs) and/or detection error rates (DERs).

  • Patent number: 8718201
    Abstract: Techniques are provided for a demodulation and decoding method and apparatus for a given user equipment device to receive a one or more Orthogonal Frequency Division Multiplex (OFDM) symbols over a control channel, where the OFDM symbols comprise a plurality of resource element groups distributed in time and frequency that are combined to form control channel elements. Those resource element groups that form specific control channel elements for the user equipment device and those resource element groups that form common control channel elements for one or more user equipment devices including the given user equipment device are identified. The resource element groups that form the specific control channel elements and the resource element groups that form the common control channel elements are demodulated to generate encoded control messages comprising one or more control channel elements.

  • Publication number: 20010041152
    Abstract: A concentric needle device for transfer of liquids from within a vial sealed with a septum. The concentric needle device for transfer of liquids includes two concentric needles. An outer needle is provided as a gas inlet and an inner needle is provided as a fluid outlet. An annulus is defined between the inner and outer needles, and through which gas enters the vial. Liquid exits through the inner needle once the terminal end is positioned in contact with or below the surface of the liquid in the vial and gas is forced through the annulus. The terminal end of the inner needle, or the fluid outlet, is disposed at a point lower than the terminal end of the outer needle, or the gas inlet. By disposing the needles concentrically, a smaller gauge needle is used for liquid transfer. When the inner needle is placed in contact with the vial septum and an axial force is placed thereon, bending of the inner needle is limited by the outer needle.
