Abstract:
Described are devices, methods, techniques and systems for locating a portable services access transceiver (PSAT) for use in aiding emergency “911” services. In one implementation, one or more conditions indicative of movement of a PSAT may initiate a process for obtaining a new estimated location of the PSAT. In another implementation, a location of a PSAT may be determined or updated using indoor navigation techniques.
Abstract:
Systems, methods, and devices of the various aspects enable identification of anomalous application behavior. A computing device processor may detect network communication activity of an application on the computing device. The processor may identify one or more device states of the computing device, and one or more categories of the application. The processor may determine whether the application is behaving anomalously based on a correlation of the detected network communication activity of the application, the identified one or more device states of the computing device, and the identified one or more categories of the application.
Abstract:
Methods and apparatuses of providing assistance data of a venue to a mobile device are disclosed. According to aspects of the present disclosure, for the same area, multiple or different versions of assistance data may be generated. Restrictions may be applied by access area, such that positioning grid, heat maps, and maps can be restricted to certain sections of the venue; and point of interests (POIs) and search features may be provided based on at least one of user credentials, time-based restrictions, ticket-based restrictions, or loyalty-based restrictions, or any combination thereof.
Abstract:
Disclosed are systems, apparatus, devices, methods, computer program products, and other implementations, including a method that includes determining at a mobile device whether verbal input from a user is required to determine position of location of the user. The method also includes, in response to a determination that the verbal input from the user is required to determine the position of the location of the user, obtaining at the mobile device verbal description data representative of one or more geographic features viewable by the user from the location of the user, identifying at the mobile device the one or more of the geographic features from the obtained verbal description data, and determining, at the mobile device, positioning information for the location of the user based, at least in part, on the one or more geographic features identified from the verbal description data.
Abstract:
Disclosed are systems, apparatus, devices, method, computer program products, and other implementations, including a method that includes capturing an image of a scene by an image capturing unit of a device that includes at least one sensor, determining relative device orientation of the device based, at least in part, on determined location of at least one vanishing point in the captured image of the scene, and performing one or more calibration operations for the at least one sensor based, at least in part, on the determined relative device orientation.
Abstract:
Systems, apparatus and methods for estimating a location of a mobile device are presented. Before computing a location estimate, the mobile device groups a plurality of access points into two or more categories (for example, a first list of access points having a first characteristic and a second list of access points having a second characteristic). Round-trip time (RTT) measurements are computed for access points in the first list. A Short Interframe Space (SIFS) value may be determined for each access point in the first list or generally SIFT representing the first list as a whole. The RTT measurements are compensated with the appropriate SIFS value. The mobile device then computes its location or position fix estimate using the compensated RTT values while excluding less accurate RTT values from other access points. As a result, the location estimate eliminates adverse influent from some access points.
Abstract:
Example methods, apparatuses, or articles of manufacture are disclosed herein that may be utilized, in whole or in part, to facilitate or support one or more operations or techniques for detecting location changes and monitoring assistance data via scanning for use in or with a mobile device. Briefly, in accordance with at least one implementation, a method may include obtaining, at a mobile device, a rough estimate of a location of the mobile device; identifying a plurality of transmitters within a signal acquisition range of the roughly estimated location; transmitting probe requests addressed to at least some of the transmitters; and selectively initiating a passive scan at a receiver of the mobile device if a number of responses to the probe requests received from the transmitters is less than a threshold number.
Abstract:
The disclosure is directed to determining whether or not a mobile device is indoors. The mobile device obtains a position fix based, at least in part, on an outdoor positioning system, and obtains one or more shape-files for one or more objects that are in proximity of the position fix.
Abstract:
Systems, apparatus and methods for merging maps used by a positioning server are presented. Original maps are overlaid, concatenated or inset to create a more detailed map. The original maps are from different sources and/or in different formats. By merging or fusing maps together, a positioning server may create a better structural map, which is in turn used to create improved positioning assistance data.
Abstract:
A computing device operates to receive, from at least a first peer device, a set of metadata that includes one or more identifiers to media playback resources. The computing device operates to determine one or more filters for the set of metadata. A metadata from the set of metadata is selected based on the one or more filters. A search request is provided to a network service for a media playback resource based on the selected metadata.
