| 20130154693 | TIMING CIRCUIT CALIBRATION IN DEVICES WITH SELECTABLE POWER MODES - 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. | 06-20-2013 |
| 20130159749 | POWER CONSERVATION TECHNIQUES FOR USE IN DEVICES WITH SELECTABLE POWER MODES - Techniques are provided which may be implemented in various methods, apparatuses, and/or articles of manufacture for use in and/or with an electronic device that is operable in a plurality of selectable power modes, including at least a “higher power mode” and a “lower power mode”. In an example implementation, with an electronic device operating in a higher power mode may selectively transition to a lower power mode based, at least in part, on at least phase value obtained from a signal acquired from a ground-based transmitter. Further techniques are provided which may be implemented to allow electronic device to selectively transition from a lower power mode to one or more other selectable power modes, e.g., including various “medium power modes”, and various “higher power modes”. | 06-20-2013 |
| 20130190007 | TRANSMITTER POSITION INTEGRITY CHECKING - The subject matter disclosed herein relates to determining whether a reported position of a wireless transmitter is sufficiently accurate in accordance with an accuracy metric based at least in part on a calculated range between an estimated position of a mobile station and the reported position and also based at least in part on one or more measurements taken from one or more signals transmitted by the wireless transmitter. | 07-25-2013 |

| 20140274009 | LOCATION-AWARE NETWORK SELECTION - Systems, apparatus and methods in a mobile device for saving power by powering down all transceivers not carry traffic are presented. The traffic may be voice and/or data traffic. A mobile device may select single transceiver to carry voice traffic and the same or different transceiver to carry data traffic. A mobile device first determines its position (e.g., a coarse position estimate) then consults a database or map to determine which networks are theoretically available. The mobile device executes a rule against the theoretically available networks to select the single network, then enables the transceiver for the one network to determine if the network is actually available for use. If the database inaccurately states a network is available from a current position but the transceiver shows that the network is actually not actually available, a next network from the database or map and corresponding transceiver are selected. | 09-18-2014 |
