Abstract
A system and method for conserving power in an electronic device. The system includes a processor and a tilt sensor operatively coupled to the processor. The processor utilizes the tilt sensor to monitor a tilt angle of the electronic device, and causes the electronic device to enter a power conservation state if the tilt angle falls outside of a predetermined range. As a result, the electronic device goes into a power conservation state immediately when the electronic device is no longer in use.
Claims35
A system for conserving power in an electronic device, the circuit comprising:
- a processor;
- a tilt sensor operatively coupled to the processor, wherein the processor utilizes the tilt sensor to monitor a tilt angle of the electronic device and causes the electronic device to enter a power conservation state if the tilt angle falls outside of a predetermined range;
- and
- an angle measuring unit for storing the predetermined range and for comparing a current tilt angle to the predetermined range.
(canceled)
A system for conserving power in an electronic device, the circuit comprising:
- a processor;
- a tilt sensor operatively coupled to the processor, wherein the processor utilizes the tilt sensor to monitor a tilt angle of the electronic device and causes the electronic device to enter a power conservation state if the tilt angle falls outside of a predetermined range, wherein the tilt sensor comprises:
- a weighted device moveably coupled to the electronic device, wherein the position of the weighted device corresponds to the tilt angle;
- and
- a potentiometer operatively coupled to the weighted device, wherein the potentiometer outputs a voltage based on the position of the weighted device, and wherein the voltage corresponds to the tilt angle;
- and
- an angle measuring unit for storing the predetermined range, and for comparing a current tilt angle to the predetermined range.
A method for conserving power in an electronic device, the method comprising:
- monitoring a tilt angle of the electronic system;
