Abstract

Pagers can be inadvertently switched to the "off position which can cause the entire memory (all mes- sages including the locked messages) to be erased. When this occurs, the user is not aware of the pager being in the "off' position therefore not receiving pages.

"PAGER-OFF ALERT AND RECOVERY PROTECTION"

by Tom Rudy and Tom Holmes

  Pagers can be inadvertently switched to the "off position which can cause the entire memory (all mes- sages including the locked messages) to be erased. When this occurs, the user is not aware of the pager being in the "off' position therefore not receiving pages.

  One solution to this problem is to add memory reten- tion with a back-up battery. However, this requires adding am "erase" or "clear" memory co mmand in the operational sequence so the user can delete messages. Any new feature may disrupt the ease of use of the pager especially ifaddi- tional buttons or multiple button pressing is required to execute the new commands. Also, the additional compo- nent and manufacturing cost of the back-up cell prohibits

this implementation to a "Low Tier/Low Cost Pager:

  A better solution to the problem is to add a "Pager- Off Alert and Recovery Protection" feature. This fea- ture will provide an alert (audible, visual, vibration, etc.) when the pager is switched to the "off' position (inadvertently or not). After the pager provides a "Pager- Off' alert, the user has a specified amount of time to reactivate the pager to the "On" position therefore not losing memory and continue to receive pages. This fea- ture will not require additional buttons, components or modifications to the operational sequence. Fig. 1 is a flow chart showing the operation of...
