Abstract: A method and apparatus that monitors at least one environmental characteristic associated with a location of a wireless signal receiver (102). A determination is then made as to whether the wireless signal receiver (102) is likely to receive a wirelessly transmitted signal at its location. The determination is based at least in part upon the monitored at least one environmental characteristic that is associated with the location of the wireless signal receiver (102). The performance of the wireless signal receiver (102) is then improved based upon determining if the wireless signal receiver (102) is likely to receive a wirelessly transmitted signal.

Abstract: A portable wireless transceiver (104) includes a receiver (206) for monitoring transmissions from neighboring transceivers (106A and 106B) to select a transceiver to use for communications. The portable wireless transceiver (104) further has a motion detector (204) for determining whether or not the portable wireless transceiver (104) is moving. If the portable wireless transceiver (104) is determined to not be moving, a processor (202) alters a schedule for monitoring of neighboring transceivers (106A and 106B) so that the monitoring is performed less frequently, thereby reducing power consumption by the portable wireless transceiver (104).

Abstract: A multiple channel receiver (200) includes a communications receiver synthesizer (204) and at least one numerically controlled oscillator (NCO) (406) that produce local oscillator signals that are derived from a common reference oscillator (202). A DSP (212) and CPU (214) perform automatic frequency control (AFC) by adjustment of the reference oscillator (202) based upon a signal received by a receive channel using the local oscillator signal produced by the communications receiver synthesizer (204). The CPU (214) also provides a synchronous indication of adjustments to the reference oscillator (202) to control circuitry for the at least one NCO (406) so that the configuration of the NCO (406) can be altered so as to maintain a substantially constant frequency output during the adjustment of the reference oscillator (202).

Abstract: An object selection apparatus (100) has a geo-location processor (108) that determines the location of a device (120) at the time of an input by a user. The object selection apparatus (100) also has a bearing determination processor (104) that determines a bearing from the device (120) at the time of the user input. The object selection apparatus (100) also has a geo-content retrieval system (118) that retries information that relates to a set of objects that correspond to the location and bearing of the device (120) that was determined at the time of the input.
