Title: Kuen J Sun: Innovator in Multilayer Object Evaluation

Introduction

Kuen J Sun is a notable inventor based in Yorktown, Virginia, who has made significant contributions to the field of evaluating multilayer objects for imperfections. With a total of two patents to his name, his work focuses on advanced methods for detecting flaws in complex materials.

Latest Patents

One of Kuen J Sun's latest patents is a method and apparatus for evaluating multilayer objects for imperfections. This innovative approach involves transmitting an acoustic wave into a multilayer object arranged in a stacking direction. The wave propagates through the object and is received by another transducer/waveguide combination. The received acoustic wave is then analyzed to determine the presence or absence of imperfections such as voids, delaminations, and microcracks. The method includes generating pulse echo signals and correlating them with the imperfections, where a substantial fit of approximately 80-90% indicates an absence of flaws. Alternatively, the time intervals between distinct groups of signals can be measured to assess imperfections.
