  • Patent number: 6696922
    Abstract: An interactive pager docking system includes a docking cradle which is powered by a rechargeable battery, and includes a battery charger module which monitors the status of the battery and recharges it if necessary. It also includes a plurality of external serial ports and a serial port multiplexer, so that a number of different external peripheral devices may be connected to it. A GPS receiver communicates with the pager, so that an automatic vehicle location system may be operated employing the pager. A satellite transceiver may be connected to the docking cradle, together with an external printer, bar code scanner, and/or alarm annunciator. The docking cradle is adapted to be powered by a vehicle battery, but turns off the GPS receiver after a predetermined period of time so as not to run down the vehicle battery if the pager is not in place in the docking cradle.
