Abstract: The disclosure is directed to a fuel-air mixing device for an internal combustion engine. The fuel-air mixing includes an inner elongated hollow body portion for delivering a fuel-air mixture from a carburetor or a fuel-injection device into the inlet of the intake manifold of the engine. The device includes an outer elongated body portion within which the inner body portion is disposed. The cavity is formed between the interior surface of the outer body portion and the exterior surface of the inner body portion. The cavity is open at one end portion facing the flow of the fuel-air mixture. The opposite end of the cavity is closed. The fuel-air mixture contains droplets of fuel which pass adjacent the inner surface of the carburetor or the fuel injection device. Such droplets enter the opening of the cavity of the mixing device and accumulate therein. Additional in the mixing device enable a small portion of the flow of the fuel-air mixture to move inwardly therethrough and into the cavity.

Abstract: A sensing system for detecting the frequency and amplitude of motion of a patient's diaphragm, having a transducer for detecting movement, transvenously implantable in a patient's cardiovascular system; a lead coupled to the transducer, transvenously implanatable in a patient's cardiovascular system; and a sensing instrument coupled to the lead for correlating transducer movement with the frequency and amplitude of diaphragm motion. A method for sensing the frequency and amplitude of motion of a patient's diaphragm including transvenously implanting in a patient's cardiovascular system a transducer capable of measuring movement frequency and amplitude; detecting the frequency and amplitude of movement of the transducer; and correlating transducer movement with the frequency and amplitude of the patient's diaphragm movement.
