  • Patent number: 8599963
    Abstract: A peak to average power ratio signal is generated from a first mapping function that selects the peak to average power ratio signal that corresponds to the data rate or data format of the signal to be transmitted. The selected peak to average power ratio signal is summed with a desired average transmit power signal. The resulting summation signal is input to a second effectively continuously valued mapping function comprising a table that has a plurality of power amplifier control signal values each with a corresponding peak transmit power. Each peak transmit power signal value results in a power amplifier control signal value that achieves the best possible transmitter power efficiency while still meeting out of band spurious emissions and waveform quality requirements. The summation signal value maps to one of the power amplifier control signal value that is then used to adjust a parameter such as bias of the power amplifier.

  • Patent number: 7869776
    Abstract: A method and apparatus for regulating Tx power in a multi-rate mobile device transmitter containing signal dependent gain stages. A data rate and signal format indicator signal corresponding to the transmitted signal, and a desired reference power signal are fed to a mapper that outputs a calibration value based on the desired reference power level at the antenna. The calibration value controls the power amplifier gain characteristics in real time.

  • Patent number: 7782611
    Abstract: A computer enclosure includes a chassis and a cover. The chassis has a first hole, and the cover has a second hole which is substantially coaxial with the first hole. A securing means engages in the first and second holes for mounting the cover on the chassis. A shield is fixed on one of the chassis and the cover. The shield defines a through hole communicating an outer side of the shield with the securing means and a receiving hole intersecting the through hole. A rotating block is rotatably positioned in the receiving hole between the through hole and the securing means. The rotating block includes a blocking portion configured to block the through hole. The rotating block defines an access hole in the blocking portion. The access hole is configured to communicate the through hole with the securing means by rotating the block to align the access hole with the securing means.

  • Patent number: 7356102
    Abstract: Systems and methods are provided for controlling gain compensation over temperature and frequency variations. A variable amplifier may be used to receive a control signal and an input signal. The variable amplifier may be operable to apply a gain to the input signal to generate an output signal, wherein the gain is a function of the control signal. A summation module may be used to combine a gain reference signal and a gain variation signal to generate the control signal. The gain reference signal may be calibrated at a reference temperature and a reference frequency. A gain calibration module may be used to output the gain variation signal as a function of both a current operating temperature and a current operating frequency.
