Abstract: A mobile device may determine a set of range values between the first mobile device and the second mobile device based on a difference between the first time and the second time for ranging wireless signals. The mobile device can determine first odometry information using a first sensor on the first mobile device, the first odometry information indicating a first motion of the first mobile device during a time period. The mobile device can receive, via a data channel, second odometry information determined from second measurements captured using a second sensor on the second mobile device. The mobile device can solve an angle between a first reference frame for the first device and a second reference frame for the second device using the set of range values, and the first and second odometry information to display a directional arrow pointing to a current position of the second mobile device.

Abstract: Embodiments for a device locator application are described. In an embodiment, one or more inertial displacement measurement values may be received using the inertial sensor and received camera sensor data, a trajectory based on the one or more inertial displacement measurement values may be determined, a beacon signal from a target wireless device and determine at least one signal strength value from the beacon signal may be received, at least one proximity value to the target wireless device may be estimated based on the at least one signal strength value corresponding to at least one position along the trajectory, and an indicator of the at least one proximity value to the target wireless device may be presented along the trajectory in a user interface.

Abstract: An electronic device may use information about the location of nearby devices to make sharing with those devices more intuitive for a user. The electronic device may include control circuitry, wireless circuitry including first and second antennas, and motion sensor circuitry. The control circuitry may determine the location of a nearby electronic device by calculating the angle of arrival of signals that are transmitted by the nearby electronic device. To obtain a complete, unambiguous angle of arrival solution, the electronic device may be moved into different positions during angle of arrival measurement operations. At each position, the control circuitry may calculate a phase difference associated with the received signals. Motion sensor circuitry may gather motion data as the electronic device is moved into the different positions. The control circuitry may use the received antenna signals and the motion data to determine the complete angle of arrival solution.
