  • Patent number: 11516337
    Abstract: A mobile device can include ranging circuitry to determine distance to another mobile device. A first wireless protocol can establish an initial communication session to perform authentication and/or exchange ranging settings. A second protocol can perform ranging, and other wireless protocols can transmit content. In one example, the distance information can be used to display a relative position of another device on a user interface of a sending device. The user interface can allow a user to quickly and accurately select the recipient device for sending the data item. As other example, the distance information obtained from ranging can be used to trigger a notification (e.g., a reminder) to be output from a first mobile device or used to display a visual indicator on a receiving device. Proximity of a device (e.g., as determined by a distance) can be used to suggest recipient for a new communication.

  • Publication number: 20220301410
    Abstract: Embodiments described herein provide for a non-transitory machine-readable medium storing instructions to cause one or more processor to perform operations comprising establishing a wireless connection with a beacon peripheral, monitoring a connection state of the wireless connection, in response to detecting a loss of connection with the beacon peripheral, posting a separation notification for the beacon peripheral to a notification framework of the electronic device, deferring display of the notification during a reconnect interval, attempting to reconnect with the beacon peripheral during the reconnect interval, and displaying the separation notification via a user interface in response to a failure to reconnect with the beacon peripheral.

  • Patent number: 11451924
    Abstract: A method for identifying a second mobile device in a vicinity of a first mobile device includes performing, by the first mobile device, determining distance information corresponding to a distance between the first mobile device and the second mobile device, determining angular information indicating an angle between a pointing direction of the first mobile device and the second mobile device, determining, based on the distance information and the angular information, that a location of the second mobile device lies within a first spatial region relative to the first mobile device, and providing a user interface that displays an icon corresponding to the second mobile device in a specified position on the user interface based on the location of the second mobile device being within the first spatial region.

  • Publication number: 20220252689
    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.

  • Patent number: 11374937
    Abstract: Techniques are disclosed relating to user authentication. In some embodiments, a first computing device receives, from a second computing device, a request for a user credential to be input into an authentication prompt associated with the second device. The first computing device determines a proximity associated with the second computing device based on a received wireless location beacon and, based on the request and the determined proximity, presents a selection prompt asking a user of the first computing device to select a user credential stored in the first computing device. The first computing device then provides the selected user credential to the second computing device to input into the authentication prompt. In some embodiments, the first computing device receives the wireless location beacon from a remote controller of the second computing device and determines a proximity based on a signal strength associated with the received location beacon.

  • Publication number: 20220201429
    Abstract: Embodiments described herein provide for an electronic device comprising a wireless processor coupled with a wireless radio, memory to store instructions, and one or more processors to execute the instructions. The one or more processors, based on the instructions, are to scan for a beacon advertisement using the wireless processor, store the beacon and a timestamp in a beacon advertisement buffer in response to detection of the beacon via the wireless processor, correlate a beacon advertisement with stored location data to determine a location estimate for a device associated with the beacon advertisement, encrypt the location estimate for the beacon advertisement using a beacon identifier broadcast with the beacon identifier, and transmit a hash of the beacon identifier and an encrypted location estimate for the beacon advertisement to a device locator server.

  • Publication number: 20220191644
    Abstract: Methods and devices are provided for allowing a mobile device (e.g., a key fob or a consumer electronic device, such as a mobile phone, watch, or other wearable device) to interact with a vehicle such that a location of the mobile device can be determined by the vehicle, thereby enabling certain functionality of the vehicle. A device may include both RF antenna(s) and magnetic antenna(s) for determining a location of a mobile device relative to the vehicle. Such a hybrid approach can provide various advantages. Existing magnetic coils on a mobile device (e.g., for charging or communication) may be re-used for distance measurements that are supplemented by the RF measurements. Any device antenna may provide measurements to a machine learning model that determines a region in which the mobile device resides, based on training measurements in the regions.

  • Publication number: 20220070667
    Abstract: The presence of a wireless device and/or accessory that cannot maintain an independent network connection can be detected by network connected wireless devices and the location of the detected device and/or accessory can be reported to a device location service. As the wireless devices and/or accessories do not have independent network connections, periodic maintenance is performed on those devices by nearby owner devices to which the wireless devices and/or accessories are paired or associated. Described herein are systems, methods, and associated devices to maintain a locatable wireless device by a set of multiple owner devices for that wireless device.
