20150103817 | GLOBAL TIME SYNCHRONIZATION SERVER FOR WIRELESS DEVICES - Synchronization of communication events according to a global time base (GTB). Devices implementing the GTB may be configured to awaken and exchange discovery and service capability information over pre-scheduled channels at time points determined according to the GTB. The GTB may be correlated to Global Positioning System (GPS) system time. A global time server (GTS) is described for providing a local source of accurate clock time relative to the GTB. The GTS may aggregate multiple sources of absolute and/or relative time including GPS and WWAN, select the most accurate source for a mobile environment, track source state transitions, and manage clock drift. Global time clients (GTCs) may receive updates from the GTS and compute offsets for communication events relative to a local clock. The GTC may correct for transport errors from transmission of the updated global time value across modules or sub-components of the devices. | 04-16-2015 |

20090322605 | Methods And Apparatuses For Use With Mode-Switchable Navigation Radio - Methods and apparatuses are provided for use with mode switchable navigation radios and the like. The methods and apparatuses may be implemented to selectively switch between certain operating modes based, at least in part, a mode-switching test that takes into consideration one or more non-timed test conditions to determine if mode-switching may be enabled. | 12-31-2009 |
20110001666 | CARRIER PHASE PROCESSING IN DISCONTINUOUS SATELLITE POSITIONING SYSTEM TRACKING - Disclosed is an apparatus, system and method for location determination following a search discontinuity utilizing early sampling of a satellite positioning system signal to determine a common code phase offset, pseudorange rate and mode of location calculation. | 01-06-2011 |
20110028166 | METHOD AND SYSTEM FOR FEMTO CELL SELF-TIMING AND SELF-LOCATING - Devices and methods are provided for providing self-timing and self-locating in an access point (AP) base station. In one embodiment, the method involves receiving Satellite Positioning System (SPS) signals from a first data source (e.g., plurality of satellites), wherein the SPS signals may include SPS time data, SPS frequency data, and SPS position data. The method may further involve obtaining from a second data source (e.g., cell site, terrestrial navigation station, server, user input interface, etc.) at least one of second time data, second frequency data and second position data, and determining relative reliability of the first and second data sources. | 02-03-2011 |
20120182182 | RECOVERY FROM POSITION AND TIME OUTLIERS IN POSITIONING - A mobile device may use one or more outlier detectors to detect likelihoods that an outlier condition exists for a satellite positioning system (SPS) position fix. In some implementations, an outlier detector may compare a computed position fix to an element of assistance data to generate an outlier likelihood. A decision to perform a recovery operation may be made based, at least in part, on a generated outlier likelihood. In some implementations, a computed reliability of the position fix may also be considered in making a recovery decision. | 07-19-2012 |
20120206297 | ADAPTIVE POSITIONING SIGNAL SEARCH STRATEGY FOR A MOBILE DEVICE - Various techniques are provided which may be implemented in a mobile device to acquire a first positioning signal transmitted by a first transmitter of a first satellite in geostationary orbit, associate the first positioning signal with a coverage region to determine a rough position of the mobile device, and affect a positioning signal search strategy based, at least in part, on the rough position of the mobile device. The search strategy may identify at least one transmitter of at least one satellite in non-geostationary orbit that is estimated to be located in a position to transmit a second positioning signal within at least a portion of the coverage region, and which may be searched for by the mobile device. Such techniques may, for example, reduce a first time to a position fix in certain instances. | 08-16-2012 |
20130027248 | METHODS AND APPARATUSES FOR USE WITH MODE-SWITCHABLE NAVIGATION - Methods and apparatuses are provided for use with mode switchable navigation radios and the like. The methods and apparatuses may be implemented to selectively switch between certain operating modes based, at least in part, a mode-switching test that takes into consideration one or more non-timed test conditions to determine if mode-switching may be enabled. | 01-31-2013 |

20090264136 | SYSTEM AND/OR METHOD FOR REDUCING INITIAL POSITION UNCERTAINTY IN SPS OPERATION - The subject matter disclosed herein relates to a system and method for reducing an initial position uncertainty of a mobile station. In one example, although claimed subject matter is not so limited, a process to improve an initial position estimate comprises identifying the locations of a serving cell and at least one other landmark proximate to a receiver and determining an initial estimate of the location of the receiver based, at least in part, on the identified locations of the serving cell and the at least one other landmark. | 10-22-2009 |

20100301589 | PROTECTIVE LAYER FOR AN AIRBAG ASSEMBLY - An instrument panel assembly for a passenger vehicle is provided with a protective film. The protective film has only one unfolded layer. The film layer is sized to cover an opening in an instrument panel. The opening is sized for an airbag to deploy through. The film layer is provided with a slit for separating into portions. The portions extend through the instrument panel as the airbag deploys. The protective film prevents the airbag from being damaged. The film layer also prevents the airbag from damaging the instrument panel. The instrument panel may be provided with a door for selectively covering the opening. The instrument panel assembly may include a hinge for pivotally connecting the door to the instrument panel. | 12-02-2010 |
