POWER AND NETWORK INDEPENDENT LOCATING OF A LOST DEVICE

摘要

A broadcast from a beacon associated with a mobile device is detected, at a proximate device. The broadcast includes an identifier associated with the mobile device. The identifier is sent to a service provider system to receive a confirmation that the mobile device associated with the identifier is lost. Upon receiving the confirmation, using the proximate device, a first location of the proximate device is determined at a first time, and a first signal strength of the broadcast is measured at the first time and at the first location. A location of the beacon is computed using the first signal strength and the first location from the proximate device, and by further using a second signal strength measurement at a second location and a third signal strength at a third location.

主权项

1. A method comprising:
detecting, at a proximate device, a broadcast from a beacon associated with a mobile device, the broadcast comprising an identifier associated with the mobile device; sending the identifier to a service provider system; receiving, from the service provider system, a confirmation that the mobile device associated with the identifier is lost; determining, at the proximate device, responsive to the receiving, a first location of the proximate device at a first time; measuring, using a processor and a memory at the proximate device, a first signal strength of the broadcast at the first time and at the first location; computing a location of the beacon using the first signal strength and the first location from the proximate device, and by further using a second signal strength measurement at a second location and a third signal strength at a third location.
