Abstract:
A mobile device can monitor a current location using a multi-tier approach. A baseband subsystem can monitor a coarse location of the mobile device using various course location parameters, such as a mobile country code (MCC), a location area code (LAC), or a cell identifier (cell ID), as the mobile device moves closer to the geographic region. Upon determining that the mobile device is in a cell that intersects the geographic region, the baseband subsystem can transfer the monitoring to the application subsystem. The task can be performed when the application subsystem determines that the mobile device is currently located in the geographic region. A beacon network can provide more accurate estimates of mobile device location and advertise location based services available to the mobile device.
Abstract:
Methods, program products, and systems for selective location determination are described. A mobile device can determine a location of the mobile device using various techniques. When there is a conflict between the locations determined using different techniques, the mobile device can select a most trustworthy location from the locations, and designate the most trustworthy location as a current location of the mobile device. The mobile device can determine a first location of the mobile device (e.g., a coarse location) using a cell identifier (cell ID) of a cellular network. The mobile device can determine a second location of the mobile device (e.g., a fine location) using one or more media access control (MAC) addresses of a WLAN. The first location and second location can be associated with confidence values that can indicate trustworthiness of the first location and second location.
Abstract:
A location-aware device detects if a personal or point of interest region has been entered or exited and a current context of the device. In response, an operating mode is selected based on the region and a current context of the device. The operating mode is configurable by a user, including setting geofence parameters, context parameters and operating mode parameters.
Abstract:
Techniques of determining a path using anonymous application usage data are described. A path determination system and method can determine a location and geometrical shape of a path based on anonymous application usage data received from one or more devices. The anonymous application usage data can include an identifier or a category of the application program executed by a device, and multiple locations of the device observed while the application program executes on the device. Based on the locations, the system and method can determine a path for associating with the application program. The system and method can use metadata of the application program for identifying the path in response to a query or a request. The system and method can provide the path to a device for display in an information layer on a virtual map.
Abstract:
Methods, program products, and systems of using a mobile WAP for location and context purposes are disclosed. In general, in one aspect, a server can estimate an effective location of a wireless access gateway using harvested data. The server can harvest location data from multiple mobile devices. The harvested data can include a location of each mobile device and an identifier of a wireless access gateway that is located within a communication range of the mobile device. In some implementations, the server can identify a mobile wireless access gateway based on a distance comparison. Data indicating the mobility of a wireless access gateway can be used by a mobile device to initiate one or more actions, including managing power of the mobile device, modifying entrance and exit conditions of virtual fences and determining a context of the mobile device.
Abstract:
Methods, program products, and systems for multi-tier detection of a geofence are disclosed. In general, in one aspect, a mobile device can be configured to perform a task when the mobile device enters a geographic region. The mobile device can monitor a current location using a multi-tiered approach. A baseband subsystem can monitor a coarse location of the mobile device using a CDMA system identifier, a CDMA network identifier, a CDMA zone identifier, or a CDMA base station identifier, in that order, as the mobile device moves closer to the geographic region. The baseband subsystem can notify an application subsystem when the mobile device is in a cell that intersects the geographic region. The application subsystem can perform the task upon notification.
Abstract:
Methods, program products, and systems for managing a location database are described. A server computer can receive location information from location-aware mobile devices (e.g., GPS-enabled devices) located within a communication range of access points of a wireless communications network. The server computer can calculate average geographic locations using the received locations for each access point. Based on the average geographic locations, the server computer can assign the access points to cells of a geographic grid. The server computer can filter the access points in each cell based on popularity, stability, longevity, and freshness of the access point and the received data. When a second mobile device connects to an access point in a cell, the server computer can transmit locations of the access points in the cell and in neighboring cells to the second mobile device such that a location of the second mobile device can be estimated.

Abstract:
The present disclosure relates to methods and systems of determining swimming metrics of a user during a swimming session. The method can include receiving, by a processor circuit of a user device, motion information from one or more motion sensors of the user device; determining, by the processor circuit using the motion information, a first set of rotational data of the user device, wherein the first set of rotational data is expressed in a first frame of reference; converting, by the processor circuit, the first set of rotational data into a second set of rotational data, wherein the second set of rotational data is expressed in a second frame of reference; determining, by the processor circuit, one or more swimming metrics of the user; and outputting the one or more swimming metrics.
