  • Publication number: 20220393798
    Abstract: An audio system and method for retransmission of data packets between audio devices. The audio system includes a source device, a first audio device and a second audio device configured to receive an isochronous data stream from the source device. Each audio device is configured to eavesdrop or otherwise monitor the packets within the isochronous data stream meant for each of the audio devices and each audio device can retransmit packets from one audio device to the other in the event one audio device fails to receive a packet. The audio system is configured to operate in at least a partial retransmission mode or a total retransmission mode where the partial retransmission mode allows each audio device to selectably retransmit packets between audio devices and where the total retransmission mode requires one audio device to retransmit all packets to the other audio device.

  • Publication number: 20220390580
    Abstract: Systems and methods directed to determining the distance between two devices are disclosed. The systems and methods utilize a Bluetooth connection between a first device, such as a smartphone with an acoustic transducer, and a second device, such as an earbud with an embedded microphone, and the audio capturing capabilities of the second device to determine a distance between the two devices. The first device plays audio via the acoustic transducer. This audio is captured by a microphone of the second device. The second device transmits data including the captured audio back to the first device via the Bluetooth connection. The first device calculates a time delay from the playing of the audio to the reception of the data over the Bluetooth connection. The first device then calculates the distance based on the time delay, the latency constant, and the speed of sound.

  • Publication number: 20220391164
    Abstract: The disclosed systems and method provide for an audio playback device to form a Bluetooth connection with an audio source device based on audio generated by an acoustic transducer. The audio is encoded with Bluetooth connectivity data corresponding to the audio source device. The acoustic transducer can be arranged on the audio source device, or it can be arranged on an audio playback device connected to the audio source device via a Bluetooth connection. The audio is received by a microphone of an audio playback device. The audio playback device then extracts the Bluetooth connectivity information from the audio, and forms a Bluetooth connection with the audio source device. If the Bluetooth connection is a Broadcast Audio stream, as defined by the LE Audio standard, multiple audio playback devices can be able to connect audio source device, allowing for a communal listening experience.

  • Patent number: 11503405
    Abstract: Processes, methods, systems, and devices are disclosed for synchronizing multiple wireless data streams captured in action by various sensors, with lost data recovery. For example, a source device may have multiple sensors acquiring data and sending the data streams (e.g., via Bluetooth connections) to a target device. Timing information may be appended for each of the data streams. Data packets of the multiple data streams may be formed with the timing information. The data packets may be transmitted to a target device that is configured to synchronize the multiple data streams using the timing information. The target device, applying the example processes or techniques of this disclosure, may accurately synchronize the multiple data streams. In some cases, the target device may capture additional data streams and the processor synchronizes all data streams of both the source and the target devices.
