Abstract: An audio system, method, and computer program product for synchronizing device clocks. The systems, methods and computer program product can establish a first isochronous data stream between a peripheral device and a first device and establish a second isochronous data stream between the first device and a second device to send data between the first and second device. As the two data streams may rely on two different device clocks, e.g., one clock which defines the timing for the first isochronous data stream and a second clock which defines the timing for the second isochronous data stream, the systems, methods, and computer program disclosed herein are configured to maintain synchronization and/or synchronize the first clock with the second clock to prevent data loss due to clock drift.

Abstract: Systems and methods for broadcasting wireless data via one or more retransmission schemes to increase the packet reception in a wireless system. One or more devices of the system are configured to listen for an initial data packet from a source device. Should one or more devices successfully receive the initial packet, each device that received the packet can unconditionally retransmit a copy of the payload of the initial packet such that any device that failed to receive the initial packet payload has an opportunity to receive it during the respective retransmissions. Similarly, each device of the system can send acknowledgements to the other system devices that indicate whether they received the initial packet. Should one or more of the devices successfully receive the initial packet, the devices can conditionally retransmit a copy of the missing payload when one or more devices indicates they have failed to receive it.

Abstract: A system and method for selecting audio capture sensors of wearable devices in obtaining voice data. The method provides obtaining signals associated with the user's voice at first and second wearable devices, comparing energy levels of the first and second signals, and selecting one or more audio capture sensors based on the energy levels of each signal. Due to the symmetry of the acoustic energy produced by the user's voice to a first and second wearable device, any difference in energy level between the total energy obtained by the first wearable device and the total energy obtained by the second wearable device can be attributed solely to ambient noise. Thus, the device with the higher total energy has a lower signal-to-noise ratio and selection of an audio capture sensor of the other wearable device with a higher signal-to-noise ratio is provided to obtain voice data moving forward.

Abstract: A system and method for managing simultaneous data streams from multiple sources is provided. At least one paired audio device within the system, is a managing device and coordinates the audio playback presented in each paired audio device. In this way, each device can produce an audio playback associated with different streams simultaneously. In some examples, the managing device is one of the two devices or a peripheral device, e.g., a smartphone. In some examples, each data stream contains data used to generate a priority level for each data stream. The managing device can allow a data stream having a higher priority level or the data stream with a detected change to “barge-in” causing the playbacks of each device to be associated with a different data stream. Additionally, each device is capable of assuming the role of “stream scanner” to prevent uneven power consumption between the devices within the system.

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.

Abstract: Systems and methods to enable a new host device to wirelessly connect to a peripheral device without having to execute a secure pairing process. The method includes storing encryption and connection information for the peripheral device along with information identifying the peripheral device at a server. The new host device is then provided with the information identifying the peripheral device. The new host then uses the information identifying the peripheral device to obtain the encryption and connection information from the server. The new host can then use the encryption and connection information to connect and communicate with the peripheral device. The methods and systems described herein may be used, for example, to loan a peripheral device to the new host device, or to transfer the peripheral device to the new host device.
