Title: Innovations by William J. Miller

Introduction

William J. Miller is a notable inventor based in Aurora, CO (US), recognized for his contributions to ultrasonic inspection technologies. With a total of 2 patents, he has developed innovative methods and devices that enhance the inspection of cylindrical structures.

Latest Patents

Miller's latest patents include a device and method designed for ultrasonically inspecting cylinders for longitudinal and circumferential defects, as well as measuring wall thickness. This invention employs as few as one ultrasonic sensor for full immersion scanning and defect detection. The self-centering fixturing spins the cylinder, reducing vibration and allowing for fast ultrasonic scans. To create the 45-degree angle beam shear waves for circumferential scans, the ultrasonic sensor is offset from the centerline of the cylinder, ensuring the correct angle for excitation of the shear wave.

Another significant patent is the hand-held variable angle membrane (VAM) ultrasonic scanning head, which is designed for the noninvasive detection of corrosion, microbiologically influenced corrosion (MIC), and foreign objects in pipes. This scanning head consists of transmitting and receiving transducers that excite guided waves to detect issues within containers such as pipes. The system includes transducers mounted on a fluid-filled housing sealed by a membrane, allowing for effective coupling of ultrasound to the pipe wall. The transducer housings are mounted in a rigid frame that maintains a specific distance apart, enabling rotation about a pivot point. The membrane deforms to match the pipe diameter, facilitating inspections across various container sizes.
