摘要:
A satellite positioning system (SPS) receiver (104) operates according to a method (200) having the steps of measuring (201) a distance between the SPS receiver and a transmission source (301) according to a radio frequency (RF) signal transmitted by the transmission source, calculating (212) an approximate location on Earth from the distance and a location of the transmission source, and determining (214) a location fix of the SPS receiver on Earth using the approximate location. Other method and apparatus embodiments are disclosed.
摘要:
A device (100) has a housing assembly having a plurality of housing portions which can shift relative to each other, a plurality of antennas (102) distributed among the plurality of housing portions, a receiver (104A) coupled to the plurality of antennas for receiving signals carrying information from a source, and a processor (106) coupled to the receiver. The processor is programmed to sense (202) one or more operating states of the device, and identify (204) from the one or more operating states an antenna from the plurality of antennas having a probability higher than the other antennas for successfully receiving information from the source.
摘要:
A multiprocessor system (206) having a plurality of processors (304-306), each processor capable of processing at least one queue (404A-404N) of at least one service application, and at least one task (402A-402N) comprising at least one of the at least one queue; and wherein a first processor and a second processor of the plurality of processors is each programmed to delegate (602) a service application from the first processor to a queue of the at least one queue of the second processor, evaluate (604-606) the queue at the second processor according to flow control criteria, process (608) the service application at the second processor upon satisfying the flow control criteria, and reject (610) the service application at the second processor upon failing to satisfy the flow control criteria.
