Disclosed are techniques for wireless communication. In an aspect, a UE obtains measurement data associated with at least one PRS. The UE transmits, to a BS in a first L1 or L2 PSI report opportunity, a first PSI report indicative of a first set of measurement values associated with the at least one PRS based on the measurement data. The UE further transmits, to the BS in a second L1 or L2 PSI report opportunity that is subsequent to the first L1 or L2 PSI report opportunity, a second PSI report that is indicative of a second set of measurement values associated with the at least one PRS based on the measurement data, the second set of measurement values being refined from the first set of measurement values.

An information capturing device includes a positioning unit, an audiovisual recording unit and a control unit. The positioning unit tracks and acquires multiple satellite signals and calculates positioning data and a moving speed according to the satellite signals. The control unit is activated the audiovisual recording to perform audiovisual recording and controls the positioning unit to enter a first operation mode. In the first operation mode, the positioning unit updates positioning data according to a first cycle. While the audiovisual recording is performed, the control unit reads the moving speed from the positioning unit, and the control unit controls the positioning unit to switch to a second operation mode when the moving speed is less than or equal to a first threshold. In the second operation mode, the positioning unit updates the positioning data according to a second cycle longer than the first cycle.

Calibrating a pressure sensor of a mobile device incudes determining an absolute calibration value used to calibrate pressure measurements by a pressure sensor of a mobile device; determining a first revisit zone as a first location to which the mobile device repeatedly returns; determining first and second calibrations for first and second visits to the first revisit zone; determining a first relative calibration adjustment value based on a difference between the first and second calibrations; determining an adjusted absolute calibration value based on a sum of the absolute calibration value and the first relative calibration adjustment value; and estimating an altitude of the mobile device based on a pressure measurement by the pressure sensor and the adjusted absolute calibration value.

This invention is directed to a method for mapping and positioning. The method has at least three steps. The first step calls for receiving sensor data based on location and a path of movement of a mobile device. The second step calls for generating, based on the sensor data, a path estimate and a location measurement vector (LMV), wherein the LMV includes one or more measurements at each of the locations from the sensor data from each of the locations. The third step entails generating, based on the sensor data, the path estimate, and the LMV, one or more unique path features.

In one embodiment, an apparatus (12) is presented that detects wireless signals from external devices (18) that uniquely identify each of the external devices, records, in memory (30), information about the external devices without access to an external database, and compares information from the external devices to determine a relative location of the wearable device without using additional, power-hungry position location functionality if there is a threshold match in the compared information. In some embodiments, the invention uses the determined relative location to trigger an action at another device. The invention, using self-contained functionality, enables improvements in same location or home location determination accuracy, memory conservation, and power consumption.

A satellite radio wave receiving device including: one or more controllers configured to: continually perform calculation of a current location based on radio waves from positioning satellites received by a receiver; determine whether an action state of the satellite radio wave receiving device detected by an action detection sensor has changed to a stop state; in response to determining that the action state of the satellite radio wave receiving device has changed to the stop state, interrupt the calculation of the current location by causing the receiver to interrupt reception of the radio waves; and cause an output device to perform an interruption notification operation for notifying that the calculation of the current location is being interrupted.

Systems, methods, devices, computer readable media, and other various embodiments are described for location management processes in wearable electronic devices. One embodiment involves pairing a client device with a wearable device, capturing a first client location fix at a first time using the first application and location circuitry of the client device. The client device then receives content from the wearable device, where the content is associated with a content capture time and location state data. The client device then updates a location based on the available data to reconcile the different sets of location data. In some embodiments, additional sensor data, such as data from an accelerometer, is used is used to determine which location data is more accurate for certain content.

A method and tracker for determining the location of an object, such as a parcel or luggage. The tracker periodically transmits a wireless access point beacon comprising SSID (network name) and a MAC address, in accordance with an IEEE 802.11 standard, has a power storage device, and an energy harvesting module. A server monitors data from 3rd party mobile devices regarding the locations of wifi beacons, and the user is informed of the relevant location if the beacon of the tracker is uploaded to the server. When the tracker is moved and/or it comes into range of one of the wireless portable devices, the user is informed of its location. This enables indefinite tracking especially in urban areas, worldwide.
