  • Patent number: 11895468
    Abstract: In at least one embodiment, a system for synchronizing an audio stream is provided. The system includes a first loudspeaker and an audio controller. The first loudspeaker plays back a first audio output signal including first signature information. The audio controller provides a first audio input signal and superimpose the first signature information on the first audio input signal. The audio controller receives the first audio output signal including the first audio packets and the first signature information and to detect the first signature information. The audio controller determines a delay attributed to a transmission of the first audio input signal and the first audio output signal based on the first signature information and synchronizes the transmission of a second audio input signal from the audio controller to the first loudspeaker with the playback of another audio output signal from a second loudspeaker based at least on the delay.

  • Patent number: 11803245
    Abstract: One or more embodiments include a direct message handler module executing on an endpoint device, such as a direct message handler device. The direct message handler module receives first sensor data via a first sensor. The direct message handler module receives, from a first coordinator, a command to perform a first operation, the first coordinator being selected from a plurality of endpoint devices that includes the first endpoint device. In response to receiving the command, the direct message handler module performs the first operation to extract a first feature from the first sensor data. The direct message handler module transmits a first message that includes data associated with the first feature to the plurality of endpoint devices.
