Wake interval adjustment based on charge level
First Claim
Patent Images
1. A method for adjusting a wake interval in a telematics device having a charge sensor, comprising:
- cyclically providing full power from a power supply during a wake duration, and limited power from the power supply during the wake interval;
determining a charge level for a battery of the power supply using the charge sensor;
storing the charge level;
comparing the charge level to a previously stored charge; and
adjusting the wake interval based on the charge level;
wherein adjusting the wake interval comprises;
increasing the wake interval responsively to a charge level decrease; and
decreasing the wake interval responsively to a charge level increase that is proportionately greater than the charge level decrease.

Abstract
A method and system are disclosed for adjusting a wake interval in a telematics device having a charge sensor. The telematics device cyclically provides full power from a power supply during a wake duration, and limited power from the power supply during the wake interval. A charge level for a battery of the power supply is determined using the charge sensor. The wake interval is adjusted based on the charge level.

11. A system for adjusting a wake interval in a telematics device, comprising:
-
a power supply configured to provide power to a location device and a communications system; a controller operably coupled to the location device, to the communications system, to the power supply, and to a charge sensor adapted to provide charge level information to the controller for a battery of the power supply; wherein the controller is configured to permit the power supply to provide fill power to the location device and the communications system during a wake duration, and not to permit the power supply to provide full power to the location device and the communications system during the wake interval; wherein the controller comprises a memory capable of storing the charge level information; wherein the controller is adapted to compare the charge level information to previously stored charge level information; wherein the controller is adapted to adjust the wake interval responsively to the charge level information; and wherein the controller is adapted to increase the wake interval responsively to a charge level decrease, and to decrease the wake interval responsively to a charge level increase that is proportionately greater than the charge level decrease. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
