Abstract

Conventionally, selective call receivers or pagers alert users by audible alerts or vibratory alerts. Typically, a user selects an alert mode to provide alerts depending on the operating environ- ment for the pager. Appropriate selection of the alert mode ensures that the alerts are effective in operating environments having different conditions. Consequently, battery power which would otherwise be supplied to provide more alerts can therefore be saved.

AUTOMATIC ALERT SELECTION

by Leyo T. Joseph and Tan Tat Kee

  Conventionally. selective call receivers or pagers alert users by audible alerts or vibratory alerts. Typically, a user selects an alert mode to provide alerts depending on the operating environ- ment for the pager. Appropriate selection of the alert mode ensures that the alerts are effective in operating environments having different conditions. Consequently, battery power which would otherwise be supplied to provide more alerts can therefore

be saved.

  This article describes how a pager can be adapted to effectively provide alerts depending on ambient noise. By sensing the ambient noise with a micro- phone, the pager automatically selects an alert mode that is appropriate for an operating environment. Figure I shows a method for enabling an alert mode based on ambient noise.
