Abstract: A system for generating a short-range wireless data communication link through an over-the-air channel on a predetermined radio frequency (RF) carrier. The system integrates conventional RF techniques into a low-power and low-cost system for establishing short-range wireless data communication. The system generates short-range wireless data communication links between a transmitting unit (500) that transmits an operating signal carrying data, and a receiver unit (1000) that receives the operating signal without a synthesizer or a heterodyne scheme.

Abstract: A selective calling receiver with automatic memory storage and turn-on indication is disclosed. When the receiver is placed in the called state by an incoming signal, audible and/or visual indicator signals actuated by the incoming signal are automatically stopped after a predetermined period of time has elapsed and record of the called state is simultaneously kept in a memory integral to the receiver. Indication of the called state is regenerable at a later time by a switching operation. Indication of the called state is stoppable without recording such indication in memory when a manual reset operation is performed before indication of the called state is automatically stopped.
