TIMING CIRCUIT CALIBRATION IN DEVICES WITH SELECTABLE POWER MODES
First Claim
1. A method comprising, with a device operable in a plurality of selectable power modes:
- setting a timing circuit based, at least in part, on a phase value included in one or more attribute values obtained from a signal acquired from a ground-based transmitter; and
based, at least in part, on said one or more attribute values, selectively transitioning operation of said device to a lower power mode wherein at least a portion of a receiver used to acquire said signal is disabled and at least a portion of enabled device circuitry uses said timing circuit.

Abstract
Techniques are provided which may be implemented in various methods, apparatuses, and/or articles of manufacture for use by a device that is operable in a plurality of modes, including “higher power mode” and a “lower power mode”. A timing circuit may be set based, at least in part, on a phase value obtained from a signal from a ground-based transmitter, and operation of the device may be selectively transitioned to a lower power mode wherein the device uses the timing circuit. In certain example implementations, operation of the device to the lower power mode may be selectively transition and based, at least in part, on a determination that one or more attribute values satisfy a profile test indicating that the electronic device is likely to be within a characterized environment, and/or a determination that the electronic device is likely to be in a constrained motion state.
