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.

Abstract: Embodiments described herein provide for a technique to enable sensor data gathered by multiple electronic devices, such as smart home devices, to be fused into a single coordinate space to enable a higher sensor resolution at each device. For example, multiple sensor equipped devices may communicate over a network to share sensor data between devices. Each device can combine local sensor data with remote sensor data received from other devices to increase the angular resolution of the detected sensor data. To enable this combination, motion characteristics of commonly detected objects can be used to enable the devices to determine a set of relative positions. Coordinate space transformations can then be computed based on the relative positions. Sensor data can be fused using the determined coordinate space transformations.

Abstract: Systems and methods for determining fine grain motions and vibrations of live and/or inanimate objects are described based on using a radar system. For example, biometric information may be extracted from such vibrations associated with a live object. In different embodiments, processing circuitry may perform different statistical analysis on reflections from the objects. Moreover, the processing circuitry may perform different processing functions based on the statistical analysis to determine the vibrations with high accuracy. Furthermore, the processing circuitry may also select one or multiple target maps based on a field of view of the radar system for a more robust measurement of the vibrations associated with one or multiple objects.
