Abstract: A wrist-worn paging receiver provides an incoming message alarm by contacting the wrist of the user by the use of rotating cam lobes that reside inside the paging receiver and that are separated from actual contact with the user's skin by a thin, flexible membrane. Various alarm modes are provided by controlling the ratio of the period of rotation to period of rest of the cam lobes mounted on a cam shaft that is driven by an electric motor inside the paging receiver.

Abstract: A remote alarm apparatus is described. A transmitter is communicatively coupled to a primary communications device. The transmitter broadcasts a notification signal in response to a primary communications device alert. The notification signal is a phase modulated, radio frequency signal. A remote alarm indicator provides remote notification of the primary communications device alert. The remote alarm indicator includes a radio frequency receiver for receiving the notification signal, an alarm indicator, a decoder, a battery, and a switch. The decoder provides a signal to the alarm indicator corresponding to whether the notification signal has been received by the radio frequency receiver. The switch is coupled to permit deactivation of the alarm indicator. The battery provides power to the radio frequency receiver, the alarm indicator, and the decoder.
