Title: Innovations of Dennis H. Gilbert: Pioneering Ultrasonic Inspection Technologies

Introduction

Dennis H. Gilbert is an accomplished inventor based in Renton, WA, known for his contributions to ultrasonic inspection technologies. With a total of two patents to his name, he has developed innovative solutions that advance the capabilities of materials inspection.

Latest Patents

Dennis's most recent patents reflect his commitment to enhancing ultrasonic inspection systems. The first patent is for an **Echo Cancellation System**, which is designed for inspecting composite materials. This system can detect flaws near the surface of inspected parts that are typically masked by strong reflections. It works by storing an electronic signal representative of the strong surface echo in memory, which is then subtracted from the entire test piece echo signal. This differential amplification technique allows for the effective cancellation of the strong surface echo signal, thereby revealing weaker echoes from defects that are closer to the surface.

The second patent is an **Ultrasonic Transducer with Shaped Beam Intensity Profile**. This innovative transducer generates an apodized beam of ultrasonic energy using a piezoelectric crystal element housed in a specially designed casing. A tungsten-epoxy layer, which has a thicker periphery compared to the center, forms an outwardly concave surface that aids in producing a more uniform beam pattern. This advancement significantly improves the performance of ultrasonic inspections.
