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.

Abstract: A valve assembly having a cap defining a first and second fluid flow passage for allowing the flow of fluid is attached to a seat member which is coupled to an actuator. A plunger having an adjustably attached diaphragm is maintained within the seat member and the actuator, and the plunger positions the diaphragm over the first and second fluid flow passage. The actuator controls the plunger and determines the retraction of the plunger to allow fluid flow and the insertion of the plunger to prevent fluid flow.
