Publication number: 20240077417Abstract: The disclosure relates to a non-dispersive infrared (NDIR) gas sensor which detects the concentration of gas with a simple structure and method by manufacturing an optical waveguide with a gas-permeable polymer material instead of a conventional cavity or chamber type. An optical signal travels through the optical waveguide of gas-permeable polymer by total internal reflection, and the gas naturally penetrates the optical waveguide without the use of separate inlet and outlet openings, so that the optical signal and gas particles come into contact with each other within the optical waveguide. Since the optical signal detected by a photodetector at the other end of the optical waveguide after traveling while contacting the gas particles has properties changed according to the concentration of the gas which they have contacted in the optical waveguide, it is possible to measure the concentration of a specific gas from the detected optical signal.Type: ApplicationFiled: July 11, 2023Publication date: March 7, 2024Applicant: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Jin Hwa RYU, Soocheol KIM, Hyunseok KIM, So Yung PARK, Hoe-Sung YANG, Kang Bok LEE, Kwang-Soo CHO, Kyu Won HAN

Publication number: 20210123864Abstract: Provided are a fire detection apparatus and method for analyzing a spectral distribution of secondary light generated as primary light is scattered or transmitted through smoke particles to distinguish between fire smoke generated due to an actual fire and living smoke generated in daily life, thereby reducing non-fire alarms. When smoke enters the inside of the fire detection apparatus (100) due to a fire, secondary light (150) scattered or transmitted through smoke particles (140) is incident on the light receiver (120). Upon receiving the secondary light (150), the light receiver (120) outputs a spectrum (170) of the secondary light (150). The fire identification unit (160) receives and analyzes the spectrum (170) of the secondary light (150) and identifies whether the smoke particles (140) are particles of living smoke or particles of fire smoke.Type: ApplicationFiled: October 13, 2020Publication date: April 29, 2021Inventors: Hoe Sung YANG, So Yung PARK, Kang Bok LEE, Kyu Won HAN
