Title: Innovations by Thanh Nguyen
Introduction
Thanh Nguyen is an accomplished inventor based in Roanoke, VA (US). He has made significant contributions to the field of stress measurement through his innovative patents. With a total of 2 patents, Nguyen's work showcases his expertise and dedication to advancing technology.
Latest Patents
Nguyen's latest patents include the "Ultrasonic strain gage using a motorized electromagnetic acoustic transducer." This invention presents a method and apparatus for measuring stress in a specimen utilizing a motorized electromagnetic acoustic transducer (EMAT). The technology leverages the rotation of pure-mode polarization directions of SH-waves and the change in phase of waves polarized along specific directions. The method employs a rotating small-aperture EMAT, connected to a processor, to measure phase and amplitude data as a function of angle. The EMAT is strategically placed on a workpiece at the location where stress is to be measured. The acoustic birefringence B is determined from the normalized difference of these phases. An algorithm calculates values of B and &PHgr; after the workpiece is stressed or its stress state is altered. The values are measured again at the same location, allowing for the determination of stress from the change in B and &PHgr;.
