Abstract: Described herein are techniques to enable a mobile device to perform multi-source estimation of an altitude for a location. A baseline altitude may be determined at ground level for a location and used to calibrate a barometric pressure sensor on the mobile device. The calibrated barometric pressure sensor can then estimate changes in altitude relative to ground level based on detected pressure differentials, allowing a relative altitude to ground to be determined. Baseline calibration for the barometric sensor calibration can be performed to determine an ambient ground-level barometric pressure.

Abstract: Embodiments are disclosed for estimating time outdoors and in daylight based on ambient light, motion, and location sensing. In some embodiments, a method comprises detecting daylight based on an ambient light measurement, an estimated sun elevation angle and at least one confidence threshold; determining a motion or activity state of a user based on motion sensor data; determining an indoor or outdoor class based on the motion sensor data and the ambient light detections; determining user exposure time to daylight between, before or after ambient light detections, based on the motion or activity state, and the determined indoor or outdoor class; and storing or displaying the daylight time.

Abstract: Techniques are described for improving driver efficiency. An example method can include a device accessing sparse location data indicative of one or more geographic locations along a route of the user device during a first time period. The route includes a starting location data point and an ending location data point. The device can access motion data collected by the sensors of the user device. The motion data can be collected by the sensors during the first time period. After a conclusion of the first time period, the device can generate, using the sparse location data and the motion data, a dense data set to reconstruct a route that includes the starting location data point and the ending location data point. The reconstructed route can include second dense location data and velocity data. The device can store the reconstructed route in a local memory of the user device.
