Patent ID: 7600138

Claim:
A method of managing power consumed by a power-consuming circuit that receives at least one sensed signal, and processes the at least one sensed signal, the method comprising: sensing a phenomena with a sensor and generating the at least one sensed signal in response thereto; generating an output signal with the power-consuming circuit in response to the processing of the at least one sensed signal; determining a time duration after which the output signal of the power-consuming circuit is valid; determining an update rate of the output signal of the power-consuming circuit; generating a timing signal, in an oscillating module, based on the time duration and the update rate, the timing signal having an ON time and an OFF time; supplying power to the power-consuming circuit during the ON time of the timing signal and disconnecting power to the power-consuming circuit during the OFF time; providing the timing signal and the output signal of the power-consuming circuit to a storage, the storage containing at least one latch; and latching the output signal at the update rate.
