Abstract: An electronic catheter stethoscope measures and analyzes acoustic fields and dynamic pressure variations in the gaseous or liquid fluid inside a conventional medical catheter that is positioned in a patient's urologic, digestive, reproductive, cardiovascular, neurological or pulmonary system. Measurement transducers are installed in a housing connectable to multiple preselected medical catheters. The transducers detect bodily functions that are transmitted to the preselected catheter from within the body. The transducers, housing, electrical interface and signal processing electronics are positioned outside the body.

Abstract: A puck for providing a coating material in a cathodic arc coating system has a generally uniform depression formed at the outer periphery. The depression ensures that an arc from the coating apparatus will move uniformly about the outer periphery of the puck, such that a coating cloud will also be uniformly applied to parts to be coated.

Abstract: A method for coating a metal component of a gas turbine engine, the method comprising forming a cathode ingot for a cathodic arc deposition process, and performing a cathodic arc deposition process on the metal component with the cathode ingot to form a bond coat, where the formed cathode ingot comprises an MCrAlY alloy base portion and a platinum-modified aluminide outer coating disposed over the base portion.
