Publication number: 20240137511Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. In video encoding and decoding, multiple partition blocks are generated by splitting a target block. A prediction mode is derived for at least a part of the multiple partition blocks, among the multiple partition blocks, and prediction is performed on the multiple partition blocks based on the derived prediction mode. When prediction is performed on the partition blocks, information related to the target block may be used, and information related to an additional partition block, which is predicted prior to the partition block, may be used.Type: ApplicationFiled: January 4, 2024Publication date: April 25, 2024Applicants: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTE, INDUSTRY-UNIVERSITY COOPERATION FOUNDATION KOREA AEROSPACE UNIVERSITY, HANBAT NATIONAL UNIVERSITY INDUSTRY-ACADEMIC COOPERATION FOUNDATIONInventors: Jin-Ho LEE, Jung-Won KANG, Hyunsuk KO, Sung-Chang LIM, Dong-San JUN, Ha-Hyun LEE, Seung-Hyun CHO, Hui-Yong KIM, Hae-Chul CHOI, Dae-Hyeok GWON, Jae-Gon KIM, A-Ram BACK

Patent number: 11920715Abstract: A coupling assembly includes a female quick connector and a male member, wherein the male member has a latching element, a sealing section and a tip, wherein the sealing section is disposed between the latching element and the tip. The quick connector includes a retainer having at least one retaining element. The male member is in a latching position if the latching element is latched onto the at least one retaining element. The quick connector includes a verifier which is axially movable along a verification path, wherein the verification path comprises at least one locking position and at least one releasing position. The verifier in the locking position limits a movement of a section of the retainer in radial direction, so that the retainer is not actuatable in the locking position but actuatable in the releasing position of the verifier.Type: GrantFiled: March 11, 2022Date of Patent: March 5, 2024Assignee: HANIL TUBE CORPORATIONInventors: Seong-hwa Choo, Jeong-ho Lim, Dong-hyeok Lee
