Extended sleep in a wireless device. In an embodiment, synchronized parameters, used by a wireless device to define an extended-sleep cycle, are stored at a system. Based on the synchronized parameters, the system determines a transmission time at which to transmit a message over the wireless communication network such that the message will be received by the wireless device during a portion of the extended-sleep cycle during which the wireless device is monitoring paging occasions. The message is then queued until it is transmitted at the transmission time.

A method and apparatus for sensing audio frequency-pressure modulation of the moisture content of the atmosphere caused by a moisture-laden audio source, such as a live human voice, is disclosed. A first light emitter is provided to generate a first light beam. An audio source that emits moisture, and the environment, modulate the first light beam to generate a first modulated light beam. A first detector is provided to detect and demodulate the first modulated light beam to recover an uncompensated audio signal. A second light emitter is provided to generate a second light beam. The second light beam is modulated by the environment and not by the audio source to produce a second modulated light beam. A second detector is provided to detect and demodulate the second modulated light beam to recover the signal component caused by environmental conditions. A differential amplifier is provided to generate a compensated output signal representing the difference between the uncompensated audio signal and the signal component caused by environmental conditions. The output signal can be transmitted for amplification, distribution, and/or recording.

The described method and apparatus wirelessly test individual integrated circuit die on a wafer containing multiple die. The method incorporates activating a selected die on the wafer by wirelessly impacting the die with at least two beams of electromagnetic radiation so that the die receives radiation energy having at least a first energy level, thereby activating the die by causing a current to flow in the die. Each beam of electromagnetic energy individually has less than the first energy level required to activate the die. The beams of electromagnetic energy are directed so that they at least partially overlap on the selected die. In the region of overlap, the two beams together impact the die with an energy level at least equal to the first energy level required to activate the die. The method may additionally include detecting electromagnetic radiation emitted by the die in response to the electromagnetic energy received from the beams of electromagnetic energy. The apparatus includes an integrated circuit wafer and test apparatus. The integrated circuit wafer contains a plurality of individual die. Each die can be activated by directing electromagnetic energy having at least a first energy level onto that die. The test apparatus includes first and second sources of electromagnetic energy. Each source directs to a selected die on the wafer a beam of electromagnetic energy having an energy level less than the first energy level.
