Patent number: 12064359Abstract: The present invention relates to a hand motion control system and a control method thereof, and more specifically, to a hand motion control system for a myoelectric hand, and to a control method thereof. The system enables not only grasping motions for grasping an object, but also the expression of hand gestures expressing emotions or intent, based on a limited myoelectric signal transmitted via two myoelectric sensors provided on the myoelectric hand. Furthermore, the system enables a wide variety of hand postures and grasp types that are determined by the position of a thumb, which can be changed by a user, thus easily expanding the range of applications of the myoelectric hand.Type: GrantFiled: June 12, 2019Date of Patent: August 20, 2024Assignee: KOREA LABOR WELFARE CORPORATION CO., LTD.Inventors: Se Hoon Park, Jong Moon Choi, Sung Yoon Jung, Hui Tae Lee, Seung Gi Kim

Patent number: 11617665Abstract: A hybrid artificial limb device is provided. A hybrid artificial limb device according to an exemplary embodiment of the present invention comprises: a joint upper side connection member positioned at the upper side of a knee; a knee joint member connected to the joint upper side connection member; and a frame coupled to the knee joint member to be able to perform a pivot rotation, and forming a femoral part. When the frame performs a pivot rotation about the knee joint member, the passive power from the passive driving module and the active power from the active driving module may be selectively or simultaneously provided to the knee joint member.Type: GrantFiled: September 27, 2019Date of Patent: April 4, 2023Assignee: KOREA LABOR WELFARE CORPORATION CO., LTD.Inventors: Hyunjun Shin, Shinki Kim, Mankee Jeon, Hyeonseok Cho, Jong Kwon Kim, Jinkuk Park, Sehoon Park, Jongmoon Choi, Huitae Lee, Jeichung Ryu
