Abstract:
Techniques for use in a mobile device involve detecting a temperature condition at said device and, in response, operating in a limited communication state for which only emergency communication is permitted. When the mobile device receives a user-initiated communication request, the mobile device inhibits non-emergency communication but permits emergency communication despite the existence of said temperature condition.

Abstract:
Techniques for controlling a gain state of a wireless receiver involve causing the wireless receiver to enter into a sleep mode; causing the wireless receiver to exit from the sleep mode and enter into a wake-up period; providing, via a multiplexer, a stored gain control state value to the wireless receiver for use during a warm-up period of the wake-up period, the stored gain control state value being previously read from a gain controller during a previous wake-up period of the wireless receiver; and after the warm-up period of the wake up period, providing, via the multiplexer, a current gain control state value from the gain controller to the wireless receiver for use during the wake up period, the current gain control state value being based on a signal level of a currently-received signal in the wireless receiver.

Abstract:
A power management system and method for a wireless communication device generates an average desired transmit power signal based on at least one of a received signal strength indicator signal and a power control instruction signal from a base station. A power supply level adjustment signal is generated based on the data parameters of an outgoing data stream and at least one environmental information signal. A combination of the power supply level adjustment signal and the average desired transmit power or a gain control signal and an altered version of the power supply level adjustment signal is used to generate a variable power supply signal that is provided to an output amplifier block for sufficiently generating outgoing wireless device radio signals while reducing power loss in the output amplifier block.
Abstract:
An electronic circuit includes control circuitry, an analog-to-digital converter which includes a sampler, a pseudorandom noise (PN) generator configured to produce a PN signal, and a plurality of n correlators. The control circuitry is configured to control the sampler, in a sampling phase determination process, to sample a signal at a sampling period of T±T/n (where T is a symbol or chip period of the signal, and n is the number of phases of the sampled signal where n≧4) for outputting a sample set for each one of n phases of the sampled signal. Each correlator has a first input configured to receive one of the sample sets associated with a corresponding one of the n phases of the sampled signal, a second input configured to receive the 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, for use in recovering user or signaling information from the received signal.

Abstract:
Catastrophic earthquakes cause tremendous loss to people, especially when they occur unprepared. Imminent prediction of the earthquake with occurrence time, location and magnitude may give people time to prepare for it and minimize the loss. Unfortunately, imminent prediction of the earthquakes, especially those without foreshocks, is very difficult if not impossible. This invention discloses a method and system that work around the difficulty of the imminent prediction of the earthquake. Instead of trying to predict the occurrence, it triggers the earthquake artificially at a known time so that evacuation and other preparations can be accomplished prior to the triggering time of the earthquake to reduce the loss caused by the earthquake. The artificial triggering of the earthquakes may be implemented by at least one underground nuclear explosion.
