Title: Jinsoo Park and His Photoacoustic Measuring Apparatus Patents.

Introduction

Jinsoo Park is an inventor based in Hwaseong-si, South Korea. His work includes patented developments in photoacoustic measurement technology, and he is associated with Hme Square Inc. Park holds 2 patents.

Latest Patents

Park’s latest patents concern photoacoustic measuring apparatuses.

One invention describes an ultrasonic sensor configured to detect photoacoustic waves generated in a measurement target within a predetermined frequency band. The apparatus’s geometry accounts for the laser’s incidence position and beam width, the center of the photoacoustic wave-generating area, and the sensor’s position. The sensor’s frequency band may include a frequency corresponding to a wavelength equal to twice the laser beam width at the point of incidence.

Another invention combines laser-based photoacoustic detection with bioimpedance sensing. It includes a light source, a photoacoustic detector, and a contact sensor with three bioimpedance electrodes. A controller uses measured bioimpedance values to assess whether the apparatus is properly contacting the target and whether the operator and target are the same individual.

Career Highlights

Park’s listed patent work focuses on photoacoustic measurement, including sensor frequency selection and contact verification. These inventions bring together optical measurement, ultrasonic detection, and bioimpedance sensing.

Collaborations

Park’s listed coworkers include Yoonho Khang and Duhyoun Yoon. He is associated with Hme Square Inc.

Conclusion

Jinsoo Park’s two patents address complementary aspects of photoacoustic measurement, from detecting generated waves to verifying contact and user identity.
