Patents by Inventor Hyang Sook Chun

Hyang Sook Chun has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Non-contact heating type of gene amplification system
    Patent number: 9346054
    Abstract: Disclosed is a non-contact heating type gene amplification system. The non-contact heating type gene amplification system includes separate light sources for each step of a polymerase chain reaction in order to perform a high-speed temperature cycle by moving a rotation unit, in which a plurality of sample chambers are formed, to places at which the sample chambers are controlled at the temperatures corresponding to each step.
    Type: Grant
    Filed: November 15, 2010
    Date of Patent: May 24, 2016
    Assignee: KOREA FOOD RESEARCH INSTITUTE
    Inventors: Hyang Sook Chun, Sung Wook Choi, Na Ri Lee, Hyun Joo Chang
  • High resolution object inspection apparatus using terahertz wave
    Patent number: 9239287
    Abstract: An object inspection apparatus includes a terahertz wave supplying unit for generating a terahertz wave and moving a path of the terahertz wave according to time so that the terahertz wave is supplied to an object to be inspected, a focusing lens located between the terahertz wave supplying unit and the object to be inspected to focus the terahertz wave supplied by the terahertz wave supplying unit, a rotating plate having a plate shape and including a plurality of the focusing lenses with different distances from the center thereof, the rotating plate rotating in the circumferential direction so that one of the focusing lenses is located at a path of the terahertz wave according to the path movement of the terahertz wave, and a terahertz wave detecting unit for collecting and detecting a terahertz wave incident to the object to be inspected.
