    摘要: 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.

    摘要: 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.

    摘要: A first audio device exchanges first control signals with a source device and thereby receives first audio signals from the source device. A second audio device exchanges second control signals with the first audio device including information the second audio device needs to receive the first audio signals from the source device. The first control signals include communications using Bluetooth BR/EDR protocols and establish a first Bluetooth link for audio streaming from the source device to the first audio device. The second control signals include communications using Bluetooth Low Energy (BLE) protocols and transfer to the second audio device parameters of the first Bluetooth link, such that the second audio device can receive and decode an audio stream transmitted from the source device to the first audio device over the first Bluetooth link.

    摘要: Methods and systems for selective image capture based on multi-modal sensor input for a wearable device. Systems comprise a first sensor, a second sensor, and a wearable device. The first sensor is configured to capture a first image, and the second sensor is configured to collect motion data, the motion data corresponding to a relative motion between the user and the wearable device, the relative motion of the wearable device in the environment, or the motion of a body part of the user. The wearable device comprises: a communication module configured to wirelessly transmit the first image to a receiving device; and a processor configured to detect a trigger event based on the motion data collected by the second sensor, the processor further configured to initiate capture of the first image by the first sensor or transmit the first image to the receiving device by the communication module upon detection of the trigger event.
