  • Mobile station dynamic power saving control
    Patent number: 7295827
    Abstract: A mobile station in an 802.11 wireless network dynamically adjusts a number of 802.11 beacon intervals to sleep based on a power savings level and a required wake-up time to receive packets from an access point. The power savings level is based on data traffic activity in a current period. The mobile station wakes up to receive a beacon, and if a beacon is not received, the mobile station sleeps for one additional beacon period.

  • Transition-encoder sense amplifier
    Patent number: 7272029
    Abstract: A sense amplifier transition encodes an output signal onto a bus such that the bus signal only transitions when a sensed bit line has a state different from the state of a previously sensed bit line. The sense amplifier includes a storage element that changes state when the bus signal is asserted. The output of the sense amplifier is conditionally inverted based on the state of the storage element.
