Abstract: Certain aspects of the present disclosure generally relate to providing location-based health alerts based on biological indicators. In some aspects, a server may receive information that identifies a location associated with a mobile device. The server may determine a venue associated with the location. The server may identify health information associated with the venue. The health information may be based on data previously received in association with the venue. The server may provide a health alert based on the health information.

Abstract: Disclosed is a method and apparatus for capturing, collecting, and distributing event information displayed on signs. The method may include capturing, by a mobile device, an image of a sign that displays information for an event. The method may also include extracting information for the event from the captured image of the sign, and determining a location of the mobile device when the image of the sign was captured. Furthermore, the method may include uploading, to a server, a time when the image was captured, the information for the event extracted from the captured image, a location of the event determined from extracted event information, a location of the sign, or a combination thereof.

Abstract: Techniques provided herein are directed toward adjusting the rate at which a mobile device's barometric pressure sensor takes measurements, based on whether movement is detected from motion sensors, such as accelerometers, gyroscopes, and the like. Where movement is below a threshold (e.g., below a threshold speed or within a threshold distance), then the barometric pressure sensor can reduce the sampling rate to a rate that still enables the mobile device to account for changes in the weather. If movement is detected (e.g., greater than a threshold distance), then the sampling rate of the barometric pressure sensor increases (i.e., to a normal rate for determining vertical movement changes).

Abstract: One disclosed example method for coordinated lane-change negotiations between vehicles includes receiving, by a computing device of a first vehicle, a lane change request from a requesting vehicle, the requesting vehicle requesting to change to a lane of travel occupied by the first vehicle; identifying, by the computing device, a second vehicle in the lane of travel; coordinating with the second vehicle to establish a space to accommodate the requesting vehicle in the lane of travel; and transmitting a lane change response to the requesting vehicle. In some examples, methods may further include determining a distance between the first and second vehicles; determining a minimum distance to establish the space; and communicating the minimum distance and a command to change a travelling speed to the second vehicle to establish the space.

Abstract: Disclosed are systems and methods for tracking position of a mobile device within a venue. In an aspect, the mobile device obtains a plurality of light source identifiers and a plurality of location identifiers corresponding to a plurality of light sources within the venue, determines a first position of the mobile device within the venue, the first position having a first position accuracy, determines a subset of the plurality of light source identifiers corresponding to a subset of the plurality of light sources based on a location of each light source in the subset of light sources being within a threshold distance of the first position, demodulates a fragment of a light source identifier, and determines a second position of the mobile device based on one or more location identifiers corresponding to the light source, the second position having a greater position accuracy than the first position accuracy.

Abstract: Disclosed are systems, methods and techniques for calibrating a barometric pressure sensor of a mobile device. In one embodiment, a barometric pressure sensor of a mobile device may be calibrated by determining that a location of the mobile device is on a particular discrete vertical of a plurality of discrete vertical levels.

Abstract: The subject matter disclosed herein relates to a system and method for acquiring signal received from satellite vehicles (SVs) in a satellite navigation system. In one example, although claimed subject matter is not so limited, information processed in acquiring a signal from a first SV may be used in acquiring a signal from a second SV.

Abstract: A wireless communications device with positioning capabilities is used to mark a boundary of a virtual operations area, and used to mark one or more obstacles within the boundary. Virtual operations may be conducted by users having a wireless communications device, and the wireless communications device generates an alert when a user violates the boundary or is within a preset proximity to an obstacle.

Abstract: A sensor-based touchscreen assembly for use with a display panel is configured to determine a location on the display panel touched by a user. The sensor-based touchscreen assembly employs at least three sensors mounted on the display panel at different locations. The sensor-based touchscreen assembly further includes a controller coupled to the sensors. The controller is operable to determine a location on the display panel touched by a user by computing a time of difference of arrival (TDOA) of a signal (mechanical or sound wave) emitted from a touch to the sensors.

Abstract: A wireless communication device, known as a mobile station (MS), contains a conventional wireless communication system and further comprises a wireless computer network communication subsystem and may also include GPS capability. The operator of the MS may utilize any or all of these subsystems to determine the current position of the MS. Based on the current position of the MS, location-based services are provided to the MS as sales information, schedules, prices, maps, and the like. In a typical implementation a plurality of computer network access points, or beacons, are distributed throughout a geographic region and used to determine the position of the MS with a reasonably high degree of accuracy. Based on the current position of the MS, the beacons can provide location-based services.
