Title: Innovations of Stephan D Murphy

Introduction

Stephan D Murphy is an accomplished inventor based in East Cleveland, OH (US). He has made significant contributions to the field of ultrasonic inspection technology. His innovative approach has led to the development of a unique patent that enhances the inspection of cylindrical objects.

Latest Patents

Stephan holds a patent for "Phased array inspection of cylindrical objects." This invention involves a first array of ultrasonic transducers that transmits ultrasonic shear waves circumferentially around an examined cylindrical object. A second array transmits ultrasonic shear waves axially along the object. The system utilizes triggering pulses from a triggering amplifier, which are switched by a multiplexer to each individual transducer. As one transducer transmits an ultrasonic wave, the others receive reflected components. A wave travel timer measures the duration for the ultrasonic wave to travel to a defect and back. A microprocessor computes the location and orientation of reflective defects based on the measured travel time and spatial relationships.
