Patent number: 11889302Abstract: 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.Type: GrantFiled: February 5, 2021Date of Patent: January 30, 2024Assignee: Apple Inc.Inventors: Kenneth U. Victa, Benjamin A. Detwiler, Nikhil Nilakantan, Todd Wheeler, Robert W. Mayor, Brent M. Ledvina, E. Thomas Erdmann, IV, Sriram Hariharan

Publication number: 20220335807Abstract: In some embodiments, an electronic device displays visual indications to a user when an electronic device is associated with a particular user account. In some embodiments, an electronic device displays notifications of a separation with a remote locator object (and/or device). In some embodiments, an electronic device utilizes a first or second locator process for locating a device or a remote locator object based on the device or remote locator object being located. In some embodiments, an electronic device facilitates finding associated components that are at one or more physical locations. In some embodiments, an electronic device facilitates display of location information of associated components that are at one or more physical locations.Type: ApplicationFiled: April 19, 2022Publication date: October 20, 2022Inventors: Frank DE JONG, Christine A.

Patent number: 11381982Abstract: An example method includes obtaining a plurality of data items. Each data item includes an indication of a particular location, an indication that a wireless signal from a first access point was observed at that location, and an indication of a time at which the wireless signal from the first access point was observed at that location. The method also includes determining a locational stability of the first access point based on the data items. Determining the locational stability of the first access point includes clustering the plurality of data items into one or more clusters based on the locations indicated in the plurality of data items, determining whether the N most recent data items are associated with a common cluster, and determining whether a time span between the N most recent data items exceeds a threshold period of time.Type: GrantFiled: October 15, 2020Date of Patent: July 5, 2022Assignee: Apple Inc.Inventors: Margaret Tam, David Benjamin Millman, Brian Stephen Smith, Benjamin A.
