Abstract: A radio paging apparatus (100) with an LPC speech synthesizer (112). The paging apparatus of the present invention includes a controller and decoder (106), and a microprocessor controlled speech synthesizer (112) both coupled to a dual port memory (110). Digitally encoded voice messages are stored in a dual port memory (110) which includes a scratch pad area for storing control words and address pointers which indicate the attributes and location of stored digitally encoded voice messages. Messages are reconstructed by reading the control words and address pointers and processing the information stored in memory (110) with a speech synthesizer (112). The structure is adapted to store and process LPC encoded signals and it permits a message to be stored while another is being reproduced. In addition, information contained in the control words permits old or read messages to be discarded if a new message must be stored.

Abstract: An in-vehicle system (10) having a radio (12) sends and receives messages that include an identifier that uniquely identifies the vehicle and that further includes affinities as correspond to the vehicle and/or occupants of the vehicle. The messages can constitute requests for information (43), offers to provide information (44), and other representations. Such requests and offers can correlate to an information payload contained within the message and/or to the affinities set forth in the message identifier.

Abstract: A cooperative paging system (10) and radio telephone system (15) combine to provide conventional delivery of short paging messages to a combination pager/radio telephone (40) via a first communication path, while a radio telephone link operating at a higher data rate is used to deliver large data messages to the pager/radio telephone (40). The radio telephone link is formed by a transceiver section (205) of the pager/radio telephone (40) coupling to a radio telephone base station (50,52) and calling up a paging terminal (32) of the paging system (10). The paging terminal (32) retrieves the large data messages from a temporary message memory (42) to deliver to the pager/radio telephone (40).

Abstract: CM00100U This invention relates to a satellite signalling system, such as a satellite paging system, having signal coverage over a very wide area. The satellite signalling system comprises a satellite to which is coupled an antenna (88) for providing a signal beam having a variable beam area.The satellite can control the position of the antenna such that the signal beam can be directed in a predetermined sequence to a plurality of locations (28) on earth. The antenna is arranged to vary the signal beam's area in dependence on the location to which the signal beam is directed. The signal beam comprises a data signal having a data rate which can be varied by the antenna in dependence on the beam area.

Abstract: A selective call receiver for receiving and displaying information in a nationwide communication system includes circuitry to decode and process transmitted channel identification information. The receiver displays channel identification indicia in response to a user interrogation thereby confirming proper operation of the receiver on the system at the expected location.

Abstract: A selective call receiver (100) comprising a receiver (103), a controller (105), and means for presenting a recovered source document (113). The receiver (100) provides a received paging message that was generated from the facsimile message of the original source document, then the received paging message comprising at least one portion of the original source document and an address is interpreted and decoded by the controller. Using the means for presenting (113), the recovered source document can be exhibited in a format that substantially resembles the facsimile message of the original source document.

Abstract: A portable communications device is provided having a receiver and decoder for receiving and decoding transmitted selective call paging signals and messages. The receiver and decoder further provide user selectable functions for control of receiver and decoder operation. The portable communications device further includes a programmable timing circuit for generating time signals and control signals, the control signals being generated starting at preselected times for predetermined time intervals. Also included is a controller coupled to the receiver and to the decoder, and responsive to the control signals for enabling the automatic control of the user selectable functions. User selectable functions automatically controlled include address selection, address priority selection, silent mode operation, and receiver frequency control.
