Abstract: An approach is provided to detecting motion using statistical noise analysis. In the approach, reference statistics are calculated that relate to one or more noise characteristics that correspond to pixels in a first set of video images of an area being monitored. Current noise characteristics are received that correspond to the same pixels in a second set of video images of the area being monitored, with the first set of video images being captured before the second set of video images. Motion is detected in the area being monitored by comparing the reference statistics to the current noise characteristics.

Abstract: A method for increasing the bandwidth within an air interface between a mobile station and a base station is disclosed. The method involves the seizing of multiple random access channels on the dedicated control channel between a single mobile station and the base station. Individual messages are then transmitted over each of the seized random access channels on a frame-by-frame basis. Up to six channels may be seized and utilized at any particular time.

Abstract: A mobile communications device such as a pager or a cellular telephone enters a low power state more promptly than under TIA/EIA/IS-136 standards when an incoming message is pending for the device but is delayed by a first message broadcast for another such device. The device calculates the number of frames or SPACH slots required under those standards for the message for the other device; if that number is more than that reserved for the message for itself then it powers down immediately until the next paging channel slot is to be received. If the number of frames or SPACH slots required for the message for the other device is the same as or less than that reserved for the message for itself, then the device powers down immediately only for the duration of the message for the other device. By so powering down, the device achieves great savings in battery power as compared to present practices, without delay in reading incoming signals directed to the device.
