Introduction

Jeong K Na is a notable inventor based in Centerville, OH, with a remarkable portfolio of eight patents. His work primarily focuses on advancements in ultrasonic testing technologies, which have significant implications in various fields, including non-destructive testing.

Latest Patents

One of his latest patents is the "Elastomer ultrasonic coupling adaptor for focused transducers." This innovative apparatus allows for non-destructive ultrasonic testing by enabling focused immersion measurements in a contact mode. The design includes an adaptor that acoustically couples an elastomeric body to a focused ultrasonic transducer, utilizing an acoustic couplant. The housing of the adaptor is designed to receive the elastomeric body on one end and the ultrasonic transducer on the other. A cavity within the housing accommodates a liquid medium that facilitates the acoustic coupling. The elastomeric body features a frontal surface with an adjustable face slant angle, optimizing it for various test materials. Additionally, the volume of the housing cavity can be modified to alter the focal length of the ultrasonic transducer.

Another significant patent is the "Micro-resolution ultrasonic nondestructive imaging method." This system incorporates an immersion ultrasonic probe and a laser vibrometer, allowing for advanced nondestructive testing. The immersion ultrasonic probe and the sample are submerged in a fluid within an immersion tank, while the laser vibrometer remains outside. A tightly focused ultrasonic beam from the probe and a laser beam from the vibrometer are directed at the sample, achieving microscopic resolution due to the precise targeting of the ultrasonic beam.
