Patent number: 11948547Abstract: An active noise control system selects one reference sensor providing a reference signal with the largest coherence to a noise signal, among a plurality of available reference sensors, as a first entry of a reference sensor set. After selecting the first entry, the active noise control system repeats a process in which a sensor capable of providing the largest information quantity to a current reference sensor set among remaining sensors is selected as a new entry of a reference sensor set, until a desired number of sensors is reached or a desired control level is reached. When the reference sensor set is determined, the active noise control system utilizes the entries of the reference sensor set to generates a noise control signal suitable for canceling the noise signal.Type: GrantFiled: September 2, 2022Date of Patent: April 2, 2024Assignees: HYUNDAI MOTOR COMPANY, KIA CORPORATION, SEOUL NATIONAL UNIVERSITY R&DB FOUNDATIONInventors: Mun Hwan Cho, Kaang Dok Yee, Chi Sung Oh, Jung Keun You, Yun Seol Park, Yeon June Kang

Patent number: 9393339Abstract: The present invention relates to an antimicrobial filter adopting optical fibers and to an air cleaner comprising the same. More particularly, the present invention relates to an antimicrobial filter using optical fibers and to an air cleaner comprising the same, in which ultraviolet rays, visible light or natural light is emitted directly through the surface of optical fibers contained in a filtering material, thus effectively killing, in a short time, microorganisms collected in the filtering material, such as bacteria, fungi, or viruses, which are harmful to the human body. Furthermore, a photocatalyst may be coated on the surface of the filtering material to achieve an improved sterilization effect. Thus, the deterioration of the sterilization effect caused by dust particles being continuously collected at the surface of filter fiber, which are disadvantages of existing antimicrobial filters, can be overcome.Type: GrantFiled: May 8, 2013Date of Patent: July 19, 2016Assignee: KOREA INSTITUTE OF ENERGY RESEARCHInventors: Hyun-Seol Park, Jeong-Gu Yeo
