摘要： A method performed by a wearable audio output device worn by a user is provided for controlling external noise attenuated by wearable audio output device. A speech is detected from a user wearing the wearable audio output device, wherein the audio output device has active noise reduction turned on. It is determined, based on the detecting, that the user desires to speak to a subject in the vicinity of the user. In response to the determining, a level of noise reduction is reduced to enable the user to hear sounds external to the audio output device. It is determined that the user desires to speak to the subject by detecting at least one condition of a plurality of conditions.

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 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.

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： 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： Systems and methods for establishing a data connection, including a first device having a display screen to display a first image and a portable electronic device including a camera and circuitry to obtain a first characteristic of the first device or the first image via a communication; capture a captured image of the display screen of the first device; analyze the captured image to obtain a captured image characteristic; compare the captured image characteristic with the first characteristic; and, establish a connection between the first device and the portable electronic device if the captured image characteristic and the first characteristic are within a predetermined threshold. Once a connection is established, the portable electronic device is configured to continuously obtain the location, position, orientation, and/or movement of the first device and utilize this information in various applications used by the first device and/or portable electronic device.

摘要： A wireless audio device tethering system is provided for including an intermediary device having at least one wireless transceiver that is configured to establish a first wireless connection with a first wireless audio device and a second wireless connection with a second wireless audio device. The intermediary device is also configured to receive a unique identifier from the second wireless audio device and to transmit the unique identifier to the first wireless audio device in order to initiate wireless tethering between the first and second wireless audio device. Once tethering has been initiated, wireless audio signals can be streamed to the first wireless audio device and then re-streamed to the second wireless audio device.
