  • Patent number: 10805664
    Abstract: An audio distribution system includes a first playback device with a first clock time, and a second playback device with a second clock time. A wireless access point is wirelessly coupled to the first and second playback devices. The second playback device sends a time request to the first playback device via the wireless access point. The first playback device responds to the time request by sending a time response to the second playback device via the wireless access point. The second playback device calculates an update to the second clock time based on the time response, a first physical transmission rate between the second playback device and the wireless access point, and a second physical transmission rate between the first playback device and the wireless access point. The second playback device uses the update to the second clock time to playback audio in synchrony with the first playback device.

  • Patent number: 10798164
    Abstract: Introduced here are computer-implemented techniques for facilitating communication between a central processing system and one or more computing devices. The central processing system can intelligently communicate with at least some of the computing device(s). Moreover, the central processing system can simultaneously or sequentially utilize sensor data generated by multiple computing devices that are known to be associated with one another. For example, if multiple computing devices are known to be in the same general geographical location, then the central processing system may only require that one computing device upload geographical metadata for analysis. If the computing device experiences any issues that prevent the geographical metadata from being uploaded, then the central processing system can automatically prompt another computing device to temporarily or permanently assume the role of leader.
