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”. In an example implementation, a device that is operable in a plurality of selectable power modes may measure a signal strength value for a signal acquired from a ground-based transmitter, and transition operation to a lower power mode, wherein at least a portion of a receiver used to acquire the signal is disabled, based, at least in part, on: (a) a profile test indicating that the device is within a characterized environment, wherein the profile test is satisfied, at least in part, by the signal strength value; or (b) an indication based, at least in part, on the signal strength value, that the device is in a constrained motion state; or (c) both (a) and (b).
