    摘要: Systems and methods for calibrating a distance model and estimating a distance between one or more wireless devices, such as one or more Bluetooth or other types of wireless devices, for social distancing and contact tracing are described. The system includes at least one processor configured to determine an environmental fingerprint from an acoustic signal propagating within an environment, such as a room or another area. The environmental fingerprint may be compared to a database of predefined environmental fingerprints and one or more similar predefined environmental fingerprints identified. The predefined environmental fingerprints may be associated with one or more distance model parameters, which may be used to calibrate a distance model. In addition, the predefined environmental fingerprints may be associated with pretrained distance models. The calibrated or pretrained distance models may be used to process wireless signals in the environment to estimate the distance between users of wireless devices.

    摘要: This application provides an unlocking method, an electronic device, and a system, and relates to the field of terminal technologies.-The method includes: After a first electronic device determines, based on first data, that there is a first risk in an environment in which the first electronic device is located, the first electronic device establishes a connection to a second electronic device in response to a connection request sent by the second electronic device. Then, when the first electronic device determines that there is the first risk in the environment in which the first electronic device is located and a login account of the second electronic device is authorized, the first electronic device confirms to perform unlocking.

    摘要: A disclosed method may include (i) detecting, from a first sensor at a first user equipment, a vertical height of the first user equipment, (ii) detecting, from the first user equipment, a request for emergency services directed to an emergency response service, (iii) detecting an indication that a second user equipment is located within a network vicinity of the first user equipment, and (iv) improving an accuracy of detecting the vertical height of the first user equipment by adjusting the detected vertical height of the first user equipment based on a detected vertical height from a second sensor at the second user equipment. Related systems and computer-readable mediums are further disclosed.
