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.

Abstract: 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.

Abstract: Systems, methods and computer program products for determining extended coherent integration intervals based on information about user activity, dynamics and clock stability. Dynamically extending the coherent integration interval increases the signal-to-noise ratio during signal acquisition and tracking, thereby providing a benefit when antenna gain is poor, in weak signal conditions, and when being jammed, or when power needs to be conserved, compared to extending the coherent integration interval for a fixed amount of time.

Abstract: A method for identifying one or more other mobile devices in a vicinity of a first mobile device includes transmitting a first set of pulses to a second mobile device, receiving a second set of pulses from the second mobile device, and determining distance and angular information corresponding to transmission times of the first set of pulses and reception times of the second set of pulses received at the mobile device. The angular information indicates an angle between a pointing direction of the first mobile device and the second mobile device. A first probability that a position of the second mobile device lies within a first spatial region having a defined distance range and aligned with the pointing direction of the first mobile device is determined based on the distance information and the angular information. An importance metric for the second mobile device is determined based on the first probability.

Abstract: Two different wireless protocols can be used for ranging between a mobile device and an access control system (e.g., a vehicle). The first wireless protocol (e.g., Bluetooth®) can be used to perform authentication of the vehicle and exchange ranging capabilities between a mobile device (e.g., a phone or watch) and the vehicle. The second wireless protocol (e.g., ultra-wideband, UWB) can use a pulse width that is less than a pulse width used by the first wireless protocol (e.g., 1 ns v. 1 μs). The narrower pulse width can provide greater accuracy for distance (ranging) measurements.

Abstract: A method for identifying a suggested application on a mobile device is disclosed. The method includes detecting an event, determining a first location of the mobile device, identifying that the first location is within a first location region of a plurality of predetermined location regions, and then measuring one or more sensor values at one or more times. The measured sensor values may then be used to create a first-data point. In response to identifying the first location region, a plurality of clusters of data points may be retrieved. A first cluster of the plurality of clusters corresponding to the first data point may then be identified. The method may further include identifying a set of one or more applications, and then providing a message to the user based on the identified set of one or more applications.

Abstract: 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.

Abstract: A method for identifying a location of a mobile device is disclosed. The method includes during each of a plurality of instances of time: measuring one or more signal properties of one or more other devices across a time interval; obtaining an identifier from each of the one or more other devices; creating a data point to include the one or more signal properties; and storing the data point in a database. The method further includes analyzing the plurality data points in the database to determine clusters of data points; detecting an event at an input device of the mobile device; measuring one or more new signal properties of one or more of the plurality of other devices at one or more new times; creating a new data point from the one or more new signal properties; and identifying a first cluster corresponding to the new data point.
