  • Patent number: 8250448
    Abstract: Method and apparatus for concatenated and interleaved turbo product code decoding are described. The turbo encoder include a plurality of decoders coupled to receive first portion of data, a processor coupled to receive second portion of the data, and a controller providing a plurality of control signals coupled to the plurality of decoders and the processor. A control signal of the plurality of control signals coupled to the processor when enabled configures the processor to pre-calculate the second portion of the data, where the second portion of the data is trellis termination data.

  • Patent number: 8225187
    Abstract: A cyclic redundancy check (CRC) bit-slice circuit including a plurality of AND gates coupled with configuration data is described. The configuration data may enable the plurality of AND gates to provide a set of CRC input data and feedback polynomial data meeting a plurality of CRC protocols. The CRC bit-slice circuit accepts a generator polynomial as an input design parameter to build a CRC module. The modularity of the design then allows a larger CRC design to be constructed from multiple CRC modules such that wider data width may be accommodated. Several CRC modules can be cascaded to accommodate various data widths and to meet a plurality of CRC protocols.

  • Patent number: 7986223
    Abstract: An automatic signaling system for a vehicle having a turn signal light, includes a sensor configured for sensing at least a portion of a lane, and a processor coupled to the sensor, wherein the processor is configured to activate the turn signal light of the vehicle based at least on a signal received from the sensor. A method for activating a turn signal light of a vehicle includes sensing at least a portion of a lane in which the vehicle is traveling, and automatically activating a turn signal light of the vehicle based at least on the sensed portion of the lane.

  • Patent number: 7482916
    Abstract: An automatic signaling system includes a processor having an input for receiving a signal from a sensor, and an output configured to be coupled to a signaling system of a vehicle, the signaling system having a turn signal light, wherein the processor is configured to automatically activate the turn signal light based at least in part on the signal received from the sensor. A method for activating a turn signal light of a vehicle includes receiving a signal from a sensor, and automatically activating the turn signal light of the vehicle based at least in part on the received signal.

  • Patent number: 6760956
    Abstract: A clip used to attach a towel to a golf club, (e.g., a putter). The clip has an opening to attach to the golf club, and an opening to attach to the towel. The clip may be mechanically attached to the club, or may use magnets. The towel may be permanently attached to the clip or may be removable. Methods for attaching a towel to a golf club and manufacturing the clip are also provided.
