  • Patent number: 10358035
    Abstract: A hydraulic pump powering system includes a mobile vehicle, a first electric current generator device, and one or more electric pump motors. The mobile vehicle has first and second prime movers. The first electric current generator device is disposed onboard the mobile vehicle and is configured to be mechanically coupled with the first prime mover to convert movement created by the first prime mover into first electric current. The one or more electric pump motors are configured to receive the first electric current to power a hydraulic pump. The second prime mover is configured to generate movement that is converted into a propulsive force that propels the mobile vehicle. The one or more electric pump motors are configured to receive the first electric current in order to power the hydraulic pump to pump a fluid into a pumping location located off-board the mobile vehicle.

  • Patent number: 8934595
    Abstract: A low complexity system and method for operating a receiver in order to estimate an offset between the actual sample clock rate 1/TS? of a receiver and an intended sample clock rate 1/TS. The receiver captures samples of a received baseband signal at the rate 1/TS?, operates on the captured samples to generate an estimate for the clock rate offset, and fractionally resamples the captured samples using the clock rate offset. The resampled data represents an estimate of baseband symbols transmitted by the transmitter. The action of operating on the captured samples involves computing an error vector signal and then estimating the clock rate offset using the error vector signal. The error vector signal may be computed in different ways depending on whether or not carrier frequency offset and carrier phase offset are assumed to be present in the received baseband signal.

  • Patent number: 8238458
    Abstract: System and method for evaluating a transmitter by estimating IQ impairments in an orthogonal frequency division multiplexed (OFDM) signal generated by the transmitter. The OFDM signal may be received. The OFDM signal may represent a stream of symbols, each comprising a plurality of subcarriers. At least a subset of the subcarriers may be pilot subcarriers. The pilot subcarriers may be grouped into one or more groups of pilot subcarriers based on one or more conditions: a pilot subcarrier which satisfies a condition in its relation to a mirror subcarrier may be grouped with other pilot subcarriers which also satisfy the condition in relation to mirror subcarriers. An estimate of one or more of gain imbalance or quadrature skew of the OFDM signal may be calculated based on the one or more groups of pilot subcarriers and the one or more conditions. The estimate may be used to evaluate the transmitter.

  • Publication number: 20050286560
    Abstract: Provided are techniques for processing a data segment by stripping a header from a transport layer segment, performing protocol data unit detection to determine data for a protocol segment that is part of the transport layer segment data, and performing marker validation and stripping. Also provided are techniques for processing a data segment in which a header portion of a protocol data unit is received. A number of bytes of data to be stored in an application space is determined using the received header portion. Also, a next header portion of a next protocol data unit is determined using the received header portion. Then, a peek command is issued to obtain the next header portion. Additionally provided are techniques for performing cyclic redundancy checks using a stored partial cyclic redundancy check digest and residual data.
