Title: Edward R. Dykes: Innovator in Ultrasonic Inspection Technologies

Introduction

Edward R. Dykes is a notable inventor based in San Jose, CA, with a focus on advanced inspection technologies. He holds a total of 5 patents that contribute significantly to the field of nondestructive testing and inspection.

Latest Patents

One of his latest patents is an inspection tool for detecting cracks in jet pump beams of boiling water. This integrated apparatus utilizes eddy current technology to inspect the arms of jet pump beams while also employing ultrasound technology to scan the borehole region. The design of the scanner allows for precise movement of an eddy current coil in two dimensions over complex machined surfaces. The scanner features two axes of motion, enabling raster scans in either direction. The inspection payload, which includes an eddy current probe, is designed to move along the scanning axis and then index along the indexing axis, ensuring thorough data collection during motion. The unique curved track design of the scanner maintains the orientation of the eddy current probe perpendicular to the inspection surface, allowing for effective inspection of both flat surfaces and curved edges.

Another significant patent is a method and apparatus for measuring and controlling the refracted angle of ultrasonic waves propagating through a component. This innovative method directly measures the actual refracted angle of ultrasound during nondestructive examination by analyzing the slopes of characteristic echo-dynamic lines. A pattern recognition filtering method is employed to identify the echo-dynamic pattern, and the slope of an echo-dynamic line is computed after applying an edge detection algorithm to the data.
