Title: Battery economising in a communications system
Inventor: BURBIDGE RICHARD CHARLES
IPC: H04B7/26
Filed: 1998-11-11
Granted: 2000-08-11
Abstract: A method of, and communications system for, battery economising in a receiving station (CU) having a radio identity code consisting of M bits. A base station (MIU) transmits a wake-up message consisting at least two repetitions of a wake-up sequence, the wake-up sequence comprising N concatenated parts, where N is an integer, each of the N parts includes a sync code word and a different fraction M/N of bits of a radio identity code. The receiving station is energised intermittently in order to detect carrier and at least one of the N parts. In response to detecting that one of the N parts, the receiving station remains energised and analyses at least the detected one of the N parts. If the received bits of the radio identity code do not correspond to the corresponding bits of the receiving stations radio identity code, the receiving station reverts to its intermittent energisation, otherwise it remains energised to receive a message appended to the transmitted radio identity code. Each of the parts may be appended to a different sync code word identifying the part thereby enabling address identification to be carried out on only that one of the parts. Further the bits of the radio identity code may be scrambled prior to fractionalising the radio identity code.

Granted: 2001-09-21
Abstract: The present invention presents an LCD image control system with data statistics function consisting of an analog digital converter (ADC), an image scale unit, a data statistics unit, and a control unit. The ADC is used to convert analog image signals to digital image signals. The image scale unit performs interpolations of digital image signals to either enlarge or reduce the images and outputs the results to a digital display unit. The data statistics unit consists of a multiplexer, a comparator, and a counter to compute the ADC output signal distribution. The control unit controls operations of the ADC, the image unit, and the data statistics unit. By means of signal control selection, the multiplexer selects the required ADC color (R, G, or B) as the statistic input signal. The comparator compares the statistic input signal with the comparison threshold and outputs the comparison results. The counter counts the frequency of either HIGH or LOW in the comparison results and outputs the statistic value.
