He holds a total of 5 patents that showcase his expertise in ultrasonic technology and edge detection methods. His work has contributed to advancements in various industrial applications.

Latest Patents

One of Stevens' latest patents is titled "Edge detection and seam tracking with EMATs." This innovative method utilizes one or two electromagnetic acoustic transducers (EMATs) to detect the location of edges, interfaces, seams, or other structures of a workpiece. By transmitting ultrasonic waves along the workpiece and analyzing the reflected waves, the method calculates the edge's location without requiring contact between the transducer and the workpiece surface. This technique is particularly effective in accommodating rough or dirty surfaces and hostile environments.

Another significant patent is an "Ultrasonic technique for measuring the thickness of cladding on the inside surface of a vessel." This method allows for the measurement of non-welded cladding thickness from the outside diameter of a vessel. By relying on the phase change at the interface between the base metal and cladding layers, Stevens' technique can determine the cladding's presence and thickness without interrupting the vessel's operation. This method is versatile and can be employed even at elevated temperatures.
