    Abstract: PCT No. PCT/US87/00003 Sec. 371 Date Feb. 20, 1987 Sec. 102(e) Date Feb. 20, 1987 PCT Filed Jan. 2, 1987 PCT Pub. No. WO88/05184 PCT Pub. Date Jul. 14, 1988.A wrist worn device includes a digital watch circuit and a receiver circuit which responds to coded message signals including selective call signalling and message information. An input steering circuit interfaces between the watch circuit and the receiver circuit for normally providing control of the watch circuit by switches located in the device case. The normal watch functions of the switches are permanently marked on the device case. The watch circuit and the receiver circuit couple to an information selector circuit which normally selects the watch output for a common display. When coded message signals are received, the switches are enabled to control the receiver circuit, and the received message information is selected for display. New indicia, electronically selected by the information selector circuit, are displayed on the display defining the new functions of the switches.

    Abstract: A personal communications device is described including a receiver (16), intended to be worn on the body, which receives, detects and stores messages transmitted on a first communication channel (14). The stored message is then transmitted over a second communications channel (20) to a second receiver (22) which is intended to be worn on the wrist. The second receiver (22) receives, detects and stores the message, and presents the message to the user in the form of a visual display. A system transmitting synchronization signals and coded message signals is also described. In particular, coded synchronization signals are used to indicate the transmission of coded message signals or the absence of transmission of coded message signals following the transmission of the coded synchronization signal, thereby providing a battery saving function for a personal communications receiver.

    Abstract: The proposed method is characterized in that by making use of a predetermined original transmitting strategy a flag signal is transmitted by a stationary section (100) to a portable section (101), the portable section (101) receives the flag signal by making use of the predetermined receiving strategy, then estimation of signal quality based at least partially on the flag signal as being received is calculated and after calculation of the signal quality estimation a confirmation signal is transmitted to the stationary section (100). Subsequently the stationary section (100) receives the confirmation signal being sent by the portable section (101) including the signal quality estimation and in response to this reception a transmitting strategy for transmission of a message is selected from a plurality of predetermined transmitting strategies corresponding to a plurality of the signal quality estimation value ranges, and namely in compliance with the signal quality estimation. This transmitting strategy requires a corresponding receiving strategy in the portable section (101) from compatibility reasons. After transmission of the confirmation signal the portable section (101) selects from a plurality of predetermined receiving strategies corresponding to a plurality of the signal quality estimation value ranges a corresponding receiving strategy for reception of the message that is selected according to the quality estimation of the signal being transmitted in the confirmation signal without requirement for further communication with the stationary section (100). The apparatus for making the above described method consists of a control unit (104) containing a processor (203) being connected with both a transmitter (202) and a receiver (204), a first selection element (206) being connected with said processor (203) for selection of a transmitting strategy and a transmission element (212) being connected with the first selection element (206) for controlling the transmitter (202).

    Abstract: A satellite paging system is described for providing geogrpahic protocol conversion for data packet delivery to communication receivers located in a plurality of geographic areas. The system includes a transmitter for transmitting data packets formatted in a first predetermined data format to the communication satellite. The satellite includes a receiver for receiving the data packets and a programmable encoder coupled to the receiver for encoding the received data packets into encoded data packets in a second predetermined data format corresponding to the signaling requirements of each geographic delivery area. A satellite transmitter coupled to the programmable encoder then transmits the encoded data packets in the second predetermined data format to a portable communication receiver, operable in the second predetermined data format in the geographic delivery area.
