Abstract
A fully functional writing pen having incorporated therein electronic circuitry including a miniature microphone and earpiece speaker serving as a handset in a cordless telephone system. The cordless pen handset microphone and earpiece communicate via an ultrasonic link to an ultrasonic transceiver provided in a portable, pocket-sized keypad telephone dialer, which provides a cordless RF link to a base station connected by conventional means to a telephone network. The keypad dialer also may communicate on a cellular phone network using a transvertor as an adaptor, alternatively direct person-to-person communication with DPRS handsets or other similarly equipped users is possible without the telephone network. A set of depressable control buttons on the pen body enable fingertip control of the cordless telephone system, including an on-hook/off-hook switch control button and mute control button for private conversation screening during telephone calls. Upon receiving incoming calls, the pen earpiece is activated with a ringing signal so that the user can answer the call by depression of the on-hook/off-hook control button. A pen-mounted pressure sensor is provided in contact with the pen cartridge, for provision of various telephone system control functions, such as call access and volume control. An alarm clock within the portable keypad dialer signals the user via the earpiece, so that an audible reminder of important time-related activities is conveniently provided. For conference use the keypad dialer loudspeaker is switched on or off by alternate depression and release of the control buttons.
