Publication number: 20240158015Abstract: A chassis cab vehicle includes a lower frame, which constitutes a lower structure of the vehicle and is equipped with a pair of side members extending in a lengthwise direction of the vehicle. A battery is coupled between the side members. An upper body is coupled to a front portion of the lower frame and forms a cabin interior. A side sill is formed at a lower end at each side of the upper body and extends to a rear side of the cabin interior. The side sills overlap the respective side members in a lateral direction of the vehicle when coupled to the lower frame.Type: ApplicationFiled: March 7, 2023Publication date: May 16, 2024Applicants: HYUNDAI MOTOR COMPANY, KIA CORPORATIONInventors: Seung Hak Lee, Mi Ran Park, Won Hae Lee, Ha Yeon Kwon, Byung Joo Chung, Seung Min Kang, Seung Min Jeong

Image encoding/decoding method and device for performing prof, and method for transmitting bitstream
Patent number: 11949874Abstract: An image encoding/decoding method and apparatus are provided. An image decoding method according to the present disclosure is performed by an image decoding apparatus. The image decoding method may comprise deriving a prediction sample of a current block based on motion information of the current block, determining whether prediction refinement with optical flow (PROF) applies to the current block, deriving, based on that the PROF applies to the current block, a difference motion vector for each sample position in the current block, deriving a gradient for each sample position in the current block, deriving a PROF offset based on the difference motion vector and the gradient, and deriving a refined prediction sample for the current block based on the PROF offset.Type: GrantFiled: January 17, 2023Date of Patent: April 2, 2024Assignee: LG ELECTRONICS INC.Inventors: Nae Ri Park, Seung Hwan Kim, Jung Hak Nam, Hyeong Moon Jang -
Publication number: 20240061354Abstract: A method of detecting coordinates of a mark is provided. The method includes: providing a plurality of structures and the mark on a wafer, each of the plurality of structures including a plurality of mold insulating layers and a plurality of mold sacrificial layers, which are alternately stacked, an end of each of the plurality of structures including a portion having a stair shape, and the mark being between adjacent structures among the plurality of structures; forming a photoresist layer on the plurality of structures and the mark, the photoresist layer including a portion concave toward the wafer between the adjacent structures; detecting the coordinates of the mark by irradiating a beam to the mark; determining an offset of the coordinates of the mark based on a beam path changing factor; and correcting the coordinates of the mark based on the offset.Type: ApplicationFiled: August 11, 2023Publication date: February 22, 2024Applicant: Samsung Electronics Co., Ltd.Inventors: Seung Hak PARK, Won Hyeok JO, Woo-Yong JUNG

Patent number: 8273668Abstract: Methods of forming a pattern and methods of fabricating a semiconductor device having a pattern are provided, the methods include forming a self-assembly induction layer including a first region and a second region on a semiconductor substrate. A block copolymer layer is coated on the self-assembly induction layer. A first pattern, a second pattern and a third pattern are formed by phase separating the block copolymer. At least one of the first, second and third patterns may be removed to form a preliminary pattern. An etching process may be performed using the preliminary pattern as an etching mask. The first pattern contains the same material as that of the second pattern, and the third pattern contains a material different from that of the first pattern.Type: GrantFiled: July 30, 2010Date of Patent: September 25, 2012Assignees: Samsung Electronics Co., Ltd., Korea Advanced Institute of Science and TechnologyInventors: Dong Ki Yoon, Shiyong Yi, Kyoungseon Kim, Seongwoon Choi, Seokhwan Oh, Sang Ouk Kim, Seung Hak Park
