Abstract: A system for producing a notification. The system includes a control device that includes a processor, a master clock operably connected to the processor and configured to produce a master clock signal, a user interface operably connected to the processor and configured to generate an operational sequence based upon a user input, and a transmitter operably connected to the processor and configured to transmit the master clock signal and the operational sequence. The system further includes a plurality of output devices configured to establish a connection with the control device, to receive the master clock signal and the operational sequence via the established connection, and to produce a synchronized notification based upon the master clock signal and the operational sequence. The synchronized notification may include flashing lights, audible sounds, or other similar displays.

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.
