Abstract: An integrated portable phone and personal computing device has a hand-held body structure that allows the device to be comfortably held as a telephone receiver, yet is configured in such a way as not to decrease the computing capabilities of the device. The body structure provides for a display screen and input unit on a front surface of the device with a speaker and a microphone located on a side surface of the device. The arrangement for the body structure increases the useable surface area for both the display screen and input unit by providing for a combined display screen and input unit on the front surface. An activation key on the side of the unit inhibits data entry on the input unit when the device is being held as a telephone receiver without the need for a cover over the input unit.

Abstract: A paging receiver system is provided that can be integrated as one function of a multi-function electronic card device adapted for insertion into a portable computing device. The paging receiver system preferably includes a frequency agile receiver for receiving paging signals, a driver-less interface for communicating the received paging signals to the computing device and a platform-transparent memory for storing the received paging signals. The frequency agile receiver includes a frequency synthesizer for generating a user selectable down conversion frequency that is combined by a mixer to produce a received paging signal at a predetermined intermediate frequency. The driver-less interface multiplexes the received paging signal with the output of a data modem such that the computing device requires only a driver interface for the data modem in order to receive both modem data and paging information.
