Title: Innovations by Lionel Beffy

Introduction

Lionel Beffy is a notable inventor based in Courcouronnes, France. He has made significant contributions to the field of ultrasonic testing, holding 2 patents that showcase his innovative approaches to detecting internal defects in complex geometries.

Latest Patents

One of his latest patents is an "Ultrasonic testing method for a part of complex geometry." This method involves using a multielement transducer to transmit focused ultrasonic waves into the part being tested. The focusing is implemented in two modes: an electronic focusing mode and a time reversal focusing mode, which are selected based on the depth of the test zone. The time reversal mode is particularly useful for testing central zones at greater depths, while the electronic mode is used for intermediate zones.

Another significant patent is the "Method and apparatus for detecting internal defects." This invention utilizes time inversion to analyze echo signals received from a workpiece. The process involves transmitting an unfocused ultrasonic beam, receiving and inverting echo signals, and retransmitting them to detect internal defects. The apparatus includes an array of ultrasonic transducers and memory systems to facilitate this complex testing method.
