Sound-monitoring device for an industrial installation

Abstract

This patent describes an ultrasonic probe with a rotatable tip section.To provide the necessary kinematics, a universal joint couples two shafts, the distal staff housing the ultrasonic transducer elements. A control knob is used to position the distal tube section so that it can improve body wall contact.--PMF 4,341,222 43.35.Yb PATIENT SUPPORT APPARATUS FOR ULTRASOUND MAMMARY SCANNING APPARATUS Bayard G. Gardineer and James A. Heringes, assignors to Technicare Corporation 27 July 1982 (Class 128/660); filed 12 March 1980This patent describes an apparatus to support and orient a patient for ultrasonic examination of the mammary glands and axilla area. This device allows the patient's breast to be suspended in a pool of water. The ultrasonic scanning transducer is coupled to the pool of water so that a "continuous transmission medium" is provided.mPMF Because the sound does not originate at a single point but over the entire front, the correlation function peaks over a range of time differences. From the extremes of that range, one finds two hyperbolae 12 and 16 that are tangent to the front. With sound receivers also at other points, one finds other hyperbolae that are tangent to the front. If enough receivers are used, the entire reaction front can be completely located. Incidentally, this tech-! 304
