Title: Helene Marie Hebert and Her Ultrasonic Profiling Invention.

Introduction

Helene Marie Hebert is an inventor associated with Atomic Energy of Canada Limited. Based in Deep River, California, she is credited with 1 patent concerning ultrasonic inspection of components with complex surfaces.

Latest Patents

Hebert’s patent, “Profiling Tool for Determining Material Thickness for Inspection Sites Having Complex Topography,” describes an apparatus for measuring wall thickness with a phased-array ultrasonic probe. A magnetically held split ring supports a carriage that can rotate around a component while the probe operates. A transducer shoe uses a flexible membrane to form a cavity and aperture between the probe and the component, helping the system take measurements over complex features such as welds.

The apparatus can be fitted with an adaptor assembly to inspect straight sections of pipe. By processing data from multiple output pulses transmitted at different incidence angles, the system can produce an accurate wall-thickness map of the area being inspected.

Career Highlights

Hebert’s patented work addresses the practical challenge of obtaining reliable thickness measurements on components whose topography can complicate ultrasonic inspection. The invention combines a movable probe assembly, a flexible transducer shoe, and data processing to support detailed inspection.

Collaborations

Her listed coworkers include Kristopher Jones and Stuart T. Craig. The patent is associated with Atomic Energy of Canada Limited.

Conclusion

Helene Marie Hebert’s patent presents an ultrasonic profiling approach designed to improve wall-thickness inspection on complex surfaces, including welds.
