Abstract

Increasing numbers of pager users rely on silent alert features to recognize that a page has been received. These silent alerting systems most commonly rely on the prin- ciple of rotating imbalance to develop the force that is sensed by the pager wearer. If the pager is attached to a loosely fitted article of clothing, it is possible that during a silent alert the vibrational forces will not be of suffi- cient amplitude to be sensed through this "loose con- nection" to the wearer. In this case, to insure that the incoming page is recognized, a backup method of alerting is required. The invention described herein utilizes the pager's microcontroller to activate the transducer (audio alert) thereby effecting the backup alert.
