Abstract: An adapter (42) for connecting a telephone (52) to a telephone wire (40) has a subscriber line interface circuit (SLIC 113) with a jack for connecting a telephone to the SLIC, a line interface (110) for coupling to a telephone line, a signaling circuit (111) coupled to the line interface for receiving and providing subscriber line signaling on the telephone line, a codec (112) coupled to the SLIC, performing a voice coding/decoding function; and a timing circuit (202) for time multiplexing and demultiplexing of digitized voice signals between the SLIC and the line interface.

Abstract: A selective call messaging peripheral (100) capable of receiving at least one message and communicating it to an electronic information processing device (200) comprises a microcontroller (105) including a processor (106) for executing a microcode program that controls operation of the peripheral and a receiver (103) that operates to receive and demodulate an information signal to provide a recovered information signal including an address signal and the message. A correlator (109) compares the recovered address signal with a predetermined address and generates an address detection, indicating selection of the peripheral.

Abstract: An electronic device having electronic circuitry powered by a battery and having an interface for interactively coupling the electronic device to a host device, for switching the power source by which power is supplied to the electronic circuitry, and by determining (410) an interface status as being coupled to or detached from the host device. In response to determining (410) that the interface is coupled to the host device, the electronic circuit is coupled (415) to the interface such that power is supplied to the electronic circuitry from the host device. In response to determining (410) that the interface is detached from the host device, the electronic circuit is coupled (420) to the battery.

Abstract: A selective call receiver (100) for transmitting information to an external electronic device (208), such as a personal computer, includes a memory (125) for storing a predetermined status menu including at least one status category associated with internal status information of the selective call receiver (108). When the selective call receiver (100) is interactively coupled to the external electronic device (208) and receives a user-initiated status command therefrom, the predetermined status menu is retrieved from the memory (125) and transmitted to the external electronic device (208).

Abstract: A battery powered electronic device (105) for coupling to a host computer (205 ) comprises an interface (115) for transmitting data and an annunciator (340) for generating a sensible alert. The electronic device (105) further comprises interface monitoring circuitry (320) coupled to the interface (115) for determining an interface status as being active or inactive and voltage monitoring circuitry (360) coupled to a battery (355) for monitoring the battery voltage. Threshold detection circuitry (360) coupled to the voltage monitoring circuitry (360) detects that the battery voltage has exceeded a predetermined threshold voltage and generates a low battery signal in response thereto. A controller (320) receives the low battery signal and, in response thereto, provides a low battery indication to the interface (115) when the interface (115) has an active status and provides an activation signal to the annunciator (340) when the interface (115) has an inactive status.

Abstract: A method in a radio communication device (110) for receiving a lengthy message comprises the steps of receiving an RF signal (300) comprising header information (310) and submessages (305), wherein each submessage (305) is a portion of the lengthy message, and comparing header information (310) corresponding to a submessage (305) with header information corresponding to previously stored submessages, If the header information (310) corresponding to the submessage (305) is not substantially equivalent to header information corresponding to at least one of the previously stored submessages, the submessage is stored in a memory (225). The method further comprises the step of combining the submessages (305), in response to the header information (310), to form the lengthy message.

Abstract: A method and apparatus in a selective call receiver (100) choose and load a software driver program (124) into an external computer (302). The apparatus comprises a data interface (118) for coupling with the external computer (302) and a memory (122) containing pre-programmed data comprising a plurality of executable software driver programs (124). The apparatus further comprises a processor (108) coupled to the memory (122) and to the data interface (118) for controlling interactions between the memory (122) and the data interface (118).

Abstract: An antenna system for a communication receiver (100) which has an internal antenna (200) and which is coupled to a portable computer (104) to deliver received data messages thereto comprises a resonant loop antenna (16) magnetically coupled to the internal antenna (200) of the communication receiver (100), and a resonant wireframe shield (18, 40) which is coupled to the resonant loop antenna (16) and oriented perpendicular thereto. The resonant wireframe shield (18, 40) shields the communication receiver (100) from an electrical interference signal generated by the portable computer (104).
