A wireless system including a first speaker and a second speaker, where the first and second speakers communicate with each other over a wireless link. In some configurations, the first speaker includes both a primary wireless interface for receiving audio from an audio source and a secondary wireless interface transmitting a portion of the audio to the second speaker. The speaker can incorporate Near Field Communication (NFC) technology to provide the wireless link between each other. The wireless system can be configured to synchronize audio output at the speakers, and can also include a second-speaker detection mechanism that permits the first speaker to be used in either a stand-alone mode, with audio output at only the first speaker, or full-headset mode, with audio output at both speakers when the second speaker is detected within wireless range of the first speaker.

A wireless headset includes a first earpiece and a second earpiece, where the first and second earpieces communicate with each other over a wireless link. In some configurations, the first earpiece includes both a primary wireless interface for receiving audio from an audio source and a secondary wireless interface transmitting a portion of the audio to the second earpiece. The earpieces can incorporate Near Field Communication (NFC) technology to provide the wireless link between each other. The wireless headset can be configured to synchronize audio output at the earpieces, and can also include a second-earpiece detection mechanism that permits the first earpiece to be used in either a stand-alone mode, with audio output at only the first earpiece, or full-headset mode, with audio output at both earpieces when the second earpiece is detected within wireless range of the first earpiece.

Methods and systems for powering-off a Bluetooth device from a linked device are provided. A device can transmit a Bluetooth signal to a linked device to instruct the linked device to power-off. In this manner, the user need only turn off one device manually which results in all linked devices being powered off. This process can be initiated by a user through a device directly linked with the device to be powered-off or through a device that is indirectly connected, through one or more Bluetooth networks, with the device to be powered-off. This process can also be automatically initiated by a device when a set of predetermined conditions exist. Once instructed to do so, a device can initiate a predetermined power-off process which can involve terminating any ongoing functions and turning off various subsystems. In accordance with the present invention, a user can initiate a power-off of all the devices on a Bluetooth network through a single device.

A system, method and personal area network for communicating utilizing a wireless earpiece The wireless earpiece is linked with a communications device Sensor measurements of a condition of a user are performed utilizing sensors of the wireless earpiece A determination is made whether the sensor measurements exceed one or more thresholds Communications regarding the sensor measurements are sent from the wireless earpiece to the communications device regarding the condition of the user

Enhanced Biometric Control Systems for Detection of Emergency Events System and Method

An apparatus and method provides control over the relative level of audio and background sound for an audio device such as a headset or headphones. An input sound transducer (312) can be provided and configured to convert ambient acoustical pressure into an electrical background signal representing the background sound. Noise cancellation circuitry create a cancellation signal that is the inverse of the electrical background signal. A summing component is coupled to the noise cancellation component and combines the cancellation signal with an audio signal representing audio program content and provides the combined electrical signal to an output sound transducer (332) . A controller is coupled to the noise cancellation component and is configured to control the level of a cancellation signal relative to the audio signal, thereby controlling the mix of cancellation signal and audio signal reaching the output sound transducer (332) .

Headset audio bypass apparatus and method

A wireless audio distribution system includes a wireless headset for receiving a serial, digital bitstream including control data interspersed with digital data related to the audio channels, a manual audio channel selector switch; a manual volume adjustment control, an error detector and a muting circuit selectively reducing the volume level of the audio reproduced by the wireless headset in multiple steps based on errors detected by the error detector.
