摘要
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.

This application claims the benefit of priority of U.S. Provisional Application No. 63/071,988 filed Aug. 28, 2020 which is incorporated herein by reference.
Embodiments described herein relate generally to a system and method of locating wireless devices and accessories. More specifically, embodiments relate to periodic maintenance of wireless devices and accessories over a secure wireless connection.
Current security features in handheld and portable products allow the location of the product to be identified when requested by the user, such as in instances where the product is lost or stolen. If the wireless device includes positioning technology, the device can be configured to report its last location to the server computer, which is displayed by the service on a map presented to the user. Often wireless devices are used with wireless accessory devices that cannot determine their location and cannot communicate with a remote tracking services over a wide area network. These accessory devices can include, for example, wireless earbuds, headphones, headsets and other wearable devices (e.g., smartwatches, fitness bands, optical head-mounted displays) that communicate directly with the wireless device using peer-to-peer communications. For wireless accessory devices that cannot determine their location and cannot communicate with the remote tracking service, those devices cannot be tracked by the service when lost or stolen. However, the presence of those devices can be detected based on wireless signals broadcast by those devices.
