Title: Jin Hwa Ryu: Innovator in Fire Detection and Gas Sensing Technologies
Introduction
Jin Hwa Ryu is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the fields of fire detection and gas sensing technologies. With a total of 5 patents to his name, Ryu's work focuses on enhancing safety and efficiency in various applications.
Latest Patents
One of Ryu's latest inventions is a fire determination method and apparatus using multiple wavelengths. This innovative technology aims to reduce false fire alarms by distinguishing between smoke from actual fires and non-fire smoke generated in daily life. The apparatus includes a smoke detector with a light emitter that generates multiple wavelengths, a light receiver to detect scattered light from smoke particles, and a fire determiner that assesses whether the detected light signal exceeds a certain threshold. This method utilizes the characteristics of multiple wavelengths to improve photoelectric fire detection.
Another notable patent is a non-dispersive infrared (NDIR) gas sensor that employs a gas-permeable polymer optical waveguide. This invention simplifies the detection of gas concentrations by allowing gas to naturally penetrate the optical waveguide without the need for separate openings. The optical signal travels through the waveguide, and its properties change based on the concentration of the gas, enabling accurate measurement of specific gas concentrations.
