    Abstract: A device, system, and method whereby a speech-driven system used in an industrial environment distinguishes speech obtained from users of the system from other background sounds. In one aspect, the present system and method provides for a first audio stream from a user microphone collocated with a source of human speech (that is, a user) and a second audio stream from a environmental microphone which is proximate to the source of human speech but more remote than the user microphone. The audio signals from the two microphones are asynchronous. A processor is configured to identify a common, distinctive sound event in the environment, such as an impulse sound or a periodic sound signal. Based on the common sound event, the processor provides for synchronization of the two audio signals. In another aspect, the present system and method provides for a determination of whether or not the sound received at the user microphone is suitable for identification of words in a human voice, based on a comparison of sound elements in the first audio stream and the second audio stream, for example based on a comparison of the sound intensities of the sound elements in the audio streams.

    Abstract: Headset assemblies and systems for mobile application control and power savings are provided. Headset assembly includes headband with proximity sensor activation element and receiver assembly configured to be rotated with respect to the headband between a first position and a second position. Receiver assembly has memory, proximity sensor, processor communicatively coupled to memory and proximity sensor, microphone boom having first and second ends, and microphone located adjacent first end and speaker located adjacent second end. Processor comprises PIO port. Proximity sensor activation element is positioned to trigger proximity sensor to activate PIO port when receiver assembly is rotated to the second position and to deactivate PIO port when receiver assembly is rotated to first position. Proximity sensor is configured to transmit at least one signal representing receiver assembly position.
