  • Patent number: 7496060
    Abstract: A method (300) of extending battery life in a communication device having a plurality of receivers includes receiving information with a primary receiver that is configured to operate on a first network (303) and controlling a secondary receiver that is configured to operate on a second network that is independent from the first network in accordance with the information obtained with the primary receiver. A corresponding communication device (201) includes: a primary receiver (221) configured to operate on a first network (203); a secondary receiver (227, 233) configured and arranged to operate as a short range receiver with an access point (205, 207) that is independent of the first network; and a controller (225, 231, 237) that is configured to control the secondary receiver in accordance with information obtained from the primary receiver.

  • Patent number: 6178210
    Abstract: A selective call receiver unit (700) capable of reducing data distortion and improving simulcast reception includes a selective call receiver (20), a demodulator (30) coupled to the selective call receiver and a circuit (36 and 300) coupled to the demodulator for reducing data distortion received at a selective call receiver. The circuit includes a detector (350) for detecting a simulcast signal, a filter (351) for windowing the symbol edge area in the simulcast signal providing a windowed symbol edge area, and a clipping circuit (36) for clipping the windowed symbol edge area.
