Title: Innovations by Jeffrey B Wigh in Railway Defect Detection

Introduction

Jeffrey B Wigh is an accomplished inventor based in St. Joseph, MO (US), known for his significant contributions to railway technology. With a total of 4 patents, Wigh has developed innovative solutions aimed at enhancing the safety and efficiency of railway systems.

Latest Patents

Wigh's latest patents include an "Apparatus for Detecting Defects" and a "Method of Detecting Defects" in railway rails. The apparatus is designed to detect defects in a railway rail mounted on a test vehicle. It features a transducer assembly with multiple arrays of ultrasonic transducers directed toward the running surface of the rail. The beams transmitted by these arrays can be dynamically adjusted to accommodate the varying profile of the rail head and running surface. Additionally, a laser profiler, combined with a linear encoder, provides profile data to a system controller, which dynamically adjusts the focal laws for the transducers to ensure optimal inspection beam sets while the test vehicle is in motion.

The method for detecting defects involves a search unit, preferably a roller search unit (RSU), mounted on a test vehicle that maintains rolling contact with the running surface of the rails. The RSU includes a tire filled with liquid and a transducer assembly that also features arrays of ultrasonic transducers aimed at the rail's running surface. Similar to the apparatus, a laser profiler and linear encoder work together to provide profile data, allowing for dynamic adjustments to the transducer beams during operation.
