Abstract: A processing system (500) addresses an electronic display (100) comprising picture elements (pixels) (108) controlled by a plurality of first and second electrodes (106, 104). The plurality of first electrodes (106) are controlled by a plurality of periodic first drive signals (400) having a predetermined number of time slots independent of data being displayed. The plurality of second electrodes (104) are controlled by a plurality of second drive signals responsive of the data being displayed. The processing system (500) comprises calculating engine (610, 612) calculating from data being received the plurality of second drive signals for one of the plurality of second electrodes (104) for a time slot of the predetermined number of time slots.

Abstract: A selective call signaling system (10) capable of facsimile communication with a selective call receiver (40) having an active addressing display (100) comprising picture elements (pixels) (108) controlled by a plurality of first and second electrodes (106, 104). A data compressor (12) compresses the data. A transmitter (30) transmits the compressed data organized in frames to the selective call receiver (40). The selective call receiver (40) comprises a receiver (60) receiving the compressed data; the active addressing display (100) displaying the compressed data. The active addressing display (200) comprises a controller (500) controlling the plurality first electrodes (106) by a plurality of periodic first drive signals (400) represented as a sequency ordered Walsh Hadamard transform (WHT) matrix (300) and the plurality of second electrodes (104) by a plurality of second drive signals responsive to the compressed data.

Abstract: A selective call communication system (100) includes an encoder (508) for encoding and compressing the data to form compressed data, and a controller (22) for transferring the compressed data to a selective call terminal (28). The selective call terminal (28) includes a receiver (302) for receiving the compressed data. A region detector (308) for recovering the compressed data within a predefined information region (42) and a processor (20) for processing the compressed data. The processor (20) includes an identifier (310) for identifying white spaces in the compressed data and an eliminator (312) for eliminating the white spaces being identified. A transmitter (30) for transmitting the compressed data being processed to at least one selective call receiver (40).
