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.

Separation notifications for wireless accessories

Techniques and systems for unlocking a first device based on signals transmitted between the first device and a second device are disclosed. A disclosed technique includes receiving, by a first device, at least one wireless signal from a second device; transmitting, by the first device, at least one wireless signal to the second device; determining, by the first device, transit times of the at least one received wireless signal and the at least one transmitted wireless signal; determining, by the first device, one or more range measurements between the first device and the second device based at least in part on the transit times; determining, by the first device, an unlock decision based at least in part on the one or more range measurements; and causing, by at least the first device, the first device to unlock if the unlock decision is positive.

Unlocking a device

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.

Electronic devices with motion sensing and angle of arrival detection circuitry

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.

Device location finding

Embodiments described herein enable proximity enhancements for a location query performed for a target wireless device. One embodiment provides for a method to determine a range and direction to a target wireless device using one our more wireless ranging operations when the wireless communication device is within a threshold range of the target wireless device, generate an augmented reality view that includes a target position estimate for the wireless device, and present the augmented reality view that includes the target position estimate for the wireless device.

Proximity enhanced location query

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.

Enhanced automotive passive entry

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 another 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.

Ranging between mobile devices

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.

Maintenance of wireless devices by electronic devices

Embodiments that relate to pairing and finding a group of accessory devices are described. In an embodiment, a pairing status is received from a first accessory device, a request is sent to the first accessory device for information on a number of accessory devices in a device group and a number of accessory devices that are proximate to the first accessory device in the device group, information on a second accessory device in the device group is received, a continue pairing message is sent to the second accessory device if the second accessory device is proximate, and a device group profile is created with information on the number of parts and received information on the second accessory device.

Pairing groups of accessories

The present disclosure generally relates to methods and user interfaces for authentication, including providing and controlling authentication at a computer system using an external device in accordance with some embodiments.

Implementation of biometric authentication

Techniques disclosed herein relate to the pairing of a pairing initiator device and a pairing responder device for communication. The pairing initiator device and the pairing responder device range with each other to determine the distance between the pairing initiator device and the pairing responder device. Based on the distance being below a threshold distance, the pairing initiator device and the pairing responder device wirelessly pair with each other without further input from the user.

Pairing devices based on distance

Techniques for suggesting accessory devices controlled by an application executing on a mobile device are disclosed. A method includes measuring one or more sensor values using one or more sensors of a mobile device and the one or more sensor values are determined from one or more signals emitted by a first one or more accessory devices. An area of a physical space for the first one or more accessory devices can be determined based on the one or more sensor values. A second one or more accessory devices associated with the same area as the first one or more accessory devices can be suggested to a user.

Using in-home location awareness

A device implementing a system for estimating device location includes at least one processor configured to receive an estimated position based on a positioning system comprising a Global Navigation Satellite System (GNSS) satellite, and receive a set of parameters associated with the estimated position. The processor is further configured to apply the set of parameters and the estimated position to a machine learning model, the machine learning model having been trained based at least on a position of a receiving device relative to the GNSS satellite. The processor is further configured to provide the estimated position and an output of the machine learning model to a Kalman filter, and provide an estimated device location based on an output of the Kalman filter.

Machine learning assisted satellite based positioning

Maintenance of wireless devices

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.
