BATTERY CHARGE RESERVATION FOR EMERGENCY COMMUNICATIONS
First Claim
1. A wireless communications device comprising:
- electronics configured to provide communications over a communications network;
a primary battery configured to power the electronics during a power-on mode; and
a secondary battery configured to power the electronics in response to an emergency signal being received while said electronics are in a power-off mode.

Abstract
A wireless communications device and method for establishing a voltage threshold at which to turn off electronics of a wireless communications device includes determining a power threshold level at which a device is to be shut off when a battery of the device reaches or drops below the power threshold level. The determined power threshold level may be offset. The amount of power remaining for the battery in the communications device may be measured. The communication device may be shut off based on the offset power threshold level so as to preserve enough power for an emergency message to be generated and sent in the case of an emergency.

8. A method for establishing a voltage threshold at which to turn off electronics of a wireless communications device so as to preserve enough power to communicate an emergency message over a communications network, said method comprising:
-
determining an amount of power used by the wireless communications device to perform a powered-down emergency communication, including performing an emergency power-up sequence, connecting with the communications network, communicating a pre-established message to the communications network, and providing a notification that the message was communicated to a user of the wireless communications device; and establishing a voltage threshold of a battery of the wireless communications device that, when measured, causes the electronics to turn off so as to ensure that the wireless communications device has sufficient power to perform at least one powered-down emergency communication if activated by a user; and setting a turn-off voltage threshold parameter in the wireless commurications device based on the established voltage threshold that causes the wireless communications device to turn off at a certain battery voltage level to ensure sufficient battery power remains to perform at least one powered-down emergency communication. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method for establishing a power threshold at which to turn off electronics of a wireless communications device, said method comprising:
-
determining a power threshold level at which a device is to be shut off when a battery of the device reaches or drops below the power threshold level; offsetting the determined power threshold level; measuring the amount of power remaining for the battery in the communications device; and shutting off the communication device based on the offset power threshold level. - View Dependent Claims (15, 16, 17, 18, 19, 20)
