Abstract: A wireless communications device may reduce power consumption by determining that a received communications sequence is not addressed to the wireless communications device, determining how long the communications sequence will last, and placing its own receive circuitry into a low power state until the communications sequence has ended.

Abstract: An optical drive may include drive electronics and wake circuitry. The drive electronics may be arranged to operate the optical drive when in a powered mode. The wake circuitry may be arranged to generate a wake signal when the drive electronics are in an unpowered mode and when a button is pushed on the optical drive or optical media is inserted into the drive. An interface to the optical drive may include a line to carry the wake signal from the wake circuitry. A host may house the optical drive and communicate with optical drive via the interface.

Abstract: A method of placing a first call to a designated number to retrieve a voice message over a packet switched network. The voice message is retrieved from a computer and a specific code is entered to prompt the computer to call an originator of the retrieved voice message. A second call is placed, via the computer, to the originator of the retrieved voice message. The call information of a packet carrying voice information of the first call is changed to correspond with call information of the second call when the packet is sent from the first call to the second call.
