Abstract: Implementations relate to utilizing cellular signals to determine device location. In some implementations, a method includes obtaining location fingerprints, each fingerprint associated with a respective geographic location and being based on cellular signal characteristics at that location including multiple channel impulse responses (CIRs) for each location fingerprint for signals received from a plurality of cellular nodes. A fingerprint map is formed that references the location fingerprints. A request may be received for a particular geographic location of a particular user device, and a particular location fingerprint is obtained for the particular device that indicates cellular signal characteristics at the particular location, including CIRs for signals received from multiple cellular nodes.

Abstract: A vehicle includes one or more sensors and engages at least one of the one or more sensors to evaluate at least one of a count or location of vehicle occupants prior to an incident. The vehicle determines that an incident has occurred and that at least one of an evaluated count or location of at least one vehicle occupant has changed following the incident. Also, the vehicle engages at least one of the one or more sensors to detect a presence of a prior occupant outside the vehicle following the incident, responsive to determining that the at least one of the evaluated count or location of the at least one vehicle occupant changed and, responsive to detecting the presence of the prior occupant outside the vehicle following the incident, reports the presence to a 3rd party response entity.

An example vehicle disclosed herein includes a brake including a rotor and a brake pad and a brake controller to detect a request to determine a wear level of the brake pad, activate the brake to cause contact between the brake pad and the rotor, and determine, based on a latency between the activation of the brake and the contact between the brake pad and the rotor, the wear level.

Abstract: The disclosure is generally directed to systems and methods for one vehicle to follow another vehicle using alternative types of navigation assistance. In a first example method, a first vehicle uses a first type of navigation assistance to follow a second vehicle. The first type of navigation assistance can be based on satellite signals. A navigation system provided in the first vehicle may detect a loss of the first type of navigation assistance. The first vehicle may then follow the second vehicle to an intermediate location along the travel route, based on a second type of navigation assistance. In an example scenario, the second type of navigation assistance is based on a wireless signal containing information of a travel route of the second vehicle. The wireless signal may be generated by a device located in the second vehicle and/or by a device located outside the second vehicle.

Abstract: A spatial approach is provided to mitigate multipath error for an indoor pedestrian localization system using broadband communication signals, such as cellular long-term evolution (LTE) carrier phase measurements. Motion of a receiver may be used to synthesize an antenna array from time-separated elements. Received data may then be combined for synthetic aperture navigation that allows for suppressing multipath error based on determination of direction-of-arrival (DOA) of the incoming communication (e.g., LTE) signals. In one embodiment, navigation observables may be determined based on determined direction of arrival.
