摘要： A victim wireless device is detected by obtaining a set of wireless bands and a set of time periods. During a given time period a subset of wireless bands corresponding to that time period is vacant and a remaining subset of wireless bands is used to exchange data. During each of the time periods in the set of time periods: a signal, if any, is received; in the event a signal is received, the subset of vacant wireless bands corresponding to that time period is recorded; and after the set of time periods ends, it is determined whether there is a victim wireless device based at least in part on the number of vacant wireless bands recorded.

摘要： Methods and systems for power optimization of a global navigation satellite system may comprise receiving LEO RF satellite signals utilizing a LEO satellite signal receiver path (LEO Rx) in a wireless communication device (WCD). Circuitry in the LEO Rx may be configured in a powered down state based on a sleep schedule. A location of the wireless communication device may be determined utilizing LEO signals received by the LEO Rx. The sleep schedule may be based on a desired accuracy of the determined location, the relative strengths of signals received from a plurality of LEO satellites, a relevance factor generated by a position engine and communicated to the sort module, or a desired power level of the WCD. The relative strengths of received signals may be compared utilizing a sort module in a LEO demodulator in the LEO satellite signal receiver path.

摘要： Methods and systems for a dual mode global navigation satellite system may comprise selectively enabling a medium Earth orbit (MEO) radio frequency (RF) path and a low Earth orbit (LEO) RF path in a wireless communication device to receive RF satellite signals. The signals may be down-converted to determine a position of the wireless device. The signals may be down-converted utilizing local oscillator signals from a phase locked loop (PLL). The RF paths may be time-division duplexed by the selective enabling of the MEO and LEO paths. Acquisition and tracking modules in the MEO RF path may be blanked when the LEO RF path is enabled. The MEO RF path may be powered down when the LEO RF path is enabled. The signals may be down-converted to an intermediate frequency before down-converting to baseband frequencies or may be down-converted directly to baseband frequencies. In-phase and quadrature signals may be processed.

摘要： A scoreboard is disclosed comprising a scoreboard body having first player identification indicia, second player identification indicia, and scoring indicia. The scoreboard includes first and second player indicators that are movable for indicating a current score of the first or player. A first detection device for recording manual movement of the first player indicator indicates a score change of the first player, and a second detection device for recording manual movement of the second player indicator indicates a score change of the second player. A master controller is operatively connected to the detection devices, that are configured to send signals to the master controller. The master controller is configured to perform at least one of the following operations: (a) store the current score of each of the first and second players; and (b) transmit the current score of each of the first and second players over a network.
