Publication number: 20240105604Abstract: A three-dimensional (3D) semiconductor device includes a stack structure including first and second stacks stacked on a substrate. Each of the first and second stacks includes a first electrode and a second electrode on the first electrode. A sidewall of the second electrode of the first stack is horizontally spaced apart from a sidewall of the second electrode of the second stack by a first distance. A sidewall of the first electrode is horizontally spaced apart from the sidewall of the second electrode by a second distance in each of the first and second stacks. The second distance is smaller than a half of the first distance.Type: ApplicationFiled: December 1, 2023Publication date: March 28, 2024Inventors: Sung-Hun Lee, Seokjung Yun, Chang-Sup Lee, Seong Soon Cho, Jeehoon Han

Patent number: 11915525Abstract: A method and apparatus that detects whether biometric information is spoofed is provided. The method receives, from a sensor, first feature information including a static feature associated with biometric information of a user, and a dynamic feature obtained based on images related to the biometric information, detects whether the biometric information is spoofed based on a first score calculated based on the first feature information, fuses the first score with a second score calculated based on second feature information extracted from the images, based on a result of the detecting that the biometric information is spoofed based on the first score, and detects that the biometric information is spoofed based on a fused score.Type: GrantFiled: June 7, 2021Date of Patent: February 27, 2024Assignee: Samsung Electronics Co., Ltd.Inventors: Sung-Jae Cho, Kyuhong Kim, Sungun Park, Geuntae Bae, Jaejoon Han

Patent number: 11479294Abstract: A steering system of a vehicle is provided. The steering system adjusts the torsional rigidity of a torsion bar without limitation as to the configuration thereof and performs active control responding to the vehicle state by adjusting steering characteristics by controlling the torsional rigidity of the torsion bar based on the traveling condition, load state or driving mode of the vehicle. The steering system includes an MR assist device, which is coupled to an end portion of the torsion bar and adjusts the rotation and torsional rigidity of the torsion bar using an MR fluid as a working fluid.Type: GrantFiled: June 21, 2019Date of Patent: October 25, 2022Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Ji Hoon Lee, Jin Gyo Suh, Sung Han Cho, Seo An Lee

Patent number: 11046140Abstract: A rear suspension apparatus of a vehicle includes: a transverse helper leaf spring connected to a rear axle and disposed in a transverse direction; and a first stopper mechanism and a second stopper mechanism contacting the transverse helper leaf spring when the vehicle moves. The rear suspension apparatus is capable of improving riding quality by using a new spring constant value generated by the transverse helper leaf spring when freight is loaded and a vehicle body frame moves downwardly, and restricting rolling movement of the vehicle when rolling is caused, thereby increasing roll stiffness and improving driving stability.Type: GrantFiled: September 11, 2019Date of Patent: June 29, 2021Assignees: Hyundai Motor Company, Kia Motors CorporationInventor: Sung Han Cho
