Abstract

In a paging receiver with display capabilities, it is desirable to have a "pager on" indication, however, the current required to allow this indication degrades battery life. Existing products do not allow the option to defeat this feature in favor of improved battery life. This idea provides flexibility to choose between battery life and display-on time for pagers with and without timekeeping capabilities.

USER SELECTABLE DISPLAY CONTROL

by Pamela A. Rakolta, David H. Overton and Randi L. Dulaney

   In a paging receiver with display capabilities, it is desirable to have a "pager on" indication, however, the current required to allow this indication degrades battery life. Existing products do not allow the option to defeat this feature in favor of improved battery life. This idea provides flexibility to choose between battery life and display-on time for pagers with and without timekeeping capabilities.

   For manual operation, there is a means for the user to enable/disable the pager display via switch closures. Upon power-up in a paging receiver, the user would be given the option of "display off?" If selected, the display is blanked until a page is received or the user presses a button to perform a paging function. Figure 1 shows this operation. Once the pager is on, the user has the option to change the display mode by pressing a com- bination of buttons. Figure 2 shows this operation. Only manual operation is applicable to non-timekeeping pagers.

   In a pager with timekeeping capabilities, it is desirable to display time and/or date continuously. However, the user may choose to increase the battery life of the product by turning the display off when the product is not being worn. For manual operation, this could be done in three ways. Method one upon power-up of the pager is shown in Figure 1. Method two is shown...
