摘要： A method for interaction between a subscriber and an entity includes determining a current locus and acquiring change in status information for a subscriber. Preference information, for one or more searchable parameters selected by the subscriber, and association information, for one ore more contacts made by the subscriber, are acquired. First and second strength information is then acquired. First strength information pertains to the subscriber's affinity for the preference information and second strength information encompasses the subscriber's affinity for the association information. Responsive to the change in status information, a group of first entities is selected. First entity information about the group of first entities is then generated. The current locus information, the preference information, the association information, the first strength information, and the second strength information are correlated with the first entity information to produce correlation information. Finally, the correlation information is provided to the subscriber to be displayed.

摘要： A radio including a first channel for receiving signals at a first frequency and a second channel for receiving and transmitting signals at a second frequency. A multiplexer connects the first and second channels through an A/D and D/A converter to a digital signal processor. An oscillator is connected to and provides a common sampling frequency to the A/D and D/A converters. The digital signal processor controls the multiplexer and modifies the received digital signals to accommodate for the different carrier frequencies of the channels using the common sampling rate. A frequency synthesizer is connected to the oscillator and provides different frequency signals for the channels. A third channel may be provided for receiving and transmitting signals at a third frequency and is also connected to the multiplexer. The processor is capable of performing communication protocols for at least two of the channels simultaneously.

摘要： A receiver includes a controller which receives A/D sampled input signals and shifts the sampled digital signal to compensate for Doppler effect in the input signal prior to demodulation. The controller compensates for a Doppler increased frequency by shifting the sampled digital signal so as to skip a sample period every n samples. This may be achieved by decreasing a cycle of m samples by one sample period every n samples. The controller compensates for a Doppler decreased frequency by shifting the sampled digital signal so as to add a sample period every n samples. This may be achieved by repeating a sample every n samples to shift the sampled digital signal. The compensation is performed in software on a multi-threaded processor.
