Abstract: An apparatus and method for telephony tone signal and character code generation for QWERTY keyboards includes a QWERTY style keyboard, a processor and a keyboard mode control software module. The QWERTY style keyboard has a plurality of letter keys, wherein each letter key is configured to generate a unique input signal. The processor is coupled to the keyboard and is configured to convert each unique input signal generated by the letter keys into a character code and/or a telephony tone signal. The keyboard mode control software module operates on the processor, and controls whether the processor converts the unique input signals from the letter keys into character codes or telephony tone signals.

Abstract: Control circuitry is configured to control a sampler, in a sampling phase determination process, to sample a signal at a sampling period of T±T/n for outputting a sample set for each one of n phases of the sampled signal. Each one of n correlators has a first input configured to receive one of the sample sets, a second input configured to receive a PN signal, and an output which provides a correlation result from a correlation process between the sample set and the PN signal. The control circuitry is further configured to identify, from the correlation results, one of the phases associated with the optimal correlation result. The control circuitry is then configured to control the sampler, in a communication mode, to sample a received signal at a sampling period of T at the phase associated with the optimal correlation result.

Abstract: A technique for controlling operation of a communication subsystem is described. The subsystem is set to a first wake-up mode of operation, during which a state value from the system is read and stored in memory. The subsystem is then set to a sleep mode of operation after the first wake-up mode of operation, and to a second wake-up mode of operation after the sleep mode of operation. The stored state value is then read from the memory, where the subsystem is set to operate based on the read state value during a warm-up period of the second wake-up mode of operation.

Abstract: The wireless communication device includes a wireless communication transceiver to generate an oscillator control signal and an activation signal, a positioning-system receiver (e.g. a GPS receiver) to process received positioning signals, and a shared oscillator (e.g. a temperature compensated and voltage controlled crystal oscillator TCVCXO) responsive to the oscillator control signal and to generate a reference frequency signal for the wireless communication transceiver and the positioning-system receiver. The positioning-system receiver may control processing of the received positioning signals based upon the activation signal to reduce a noise contribution (e.g. phase noise) due to frequency control of the shared oscillator based upon the oscillator control signal. The activation signal may indicate that the oscillator control signal is being varied to provide frequency control or adjustment of the shared oscillator.
