Patent number: 10342724Abstract: In a joint assembly of a walking assistance robot that is capable of performing an operation with 3 degrees of freedom, similarly to a user's joint, a rolling motion and a sliding motion are simultaneously made, and a rotation center changes so that the joint assembly can make a similar motion to that of an actual knee joint of the user. Thus, when the user wears the walking assistance robot and walks, misalignment can be prevented from occurring in the knee joint.Type: GrantFiled: February 27, 2015Date of Patent: July 9, 2019Assignee: Samsung Electronics Co., Ltd.Inventors: Byungjune Choi, Yongjae Kim, Youn Baek Lee, Jeonghun Kim, Se-Gon Roh, Minhyung Lee, Jongwon Lee, Hyun Do Choi, Youngdo Kwon, ByungKwon Choi

Patent number: 10292892Abstract: A pneumatic lower extremity gait rehabilitation training system includes a support device for reducing the burden of supporting a user's body weight by lower extremity in a walking therapy, an exoskeleton rehabilitation device for adjusting the user's walking coordination at a treadmill, a center-of-gravity adjusting device for adjusting a change of upper and lower centers of gravity, and a remote monitoring device for receiving and capturing a signal of an angle displacement of a joint mechanism in a walking cycle. The user may support her/his body weight by the support device and the center-of-gravity adjusting device to reduce the gravity exerted onto the user's legs. The exoskeleton rehabilitation device improves the flexibility, safety and lightweight of walking and requires fewer driving elements. The remote monitoring device sends analyzed signals to the treadmill to adjust the user's walking speed, so as to improve the rehabilitation effect.Type: GrantFiled: September 12, 2016Date of Patent: May 21, 2019Assignee: Lunghwa University of Science and TechnologyInventors: Ching-Sheng Lee, I-Hsun Li, Hsin-Han Chiang, Lian-Wang Lee, Fu-Chen Hong, Rui-Peng Chen, Wei-Gan Chen

Patent number: 10005179Abstract: A walking assistant device may calculate a walking cycle by measuring only motion of a specific joint without a force/torque sensor (F/T sensor) of a foot, and a method of controlling the walking assistant device. The method may include measuring motion of a hinge to which different support frames are connected; overlapping a reference trajectory corresponding to the measured motion and modulation trajectories that have been modulated from the reference trajectory; correcting the overlapping trajectory to correspond to the measured motion; determining assistant torque corresponding to a phase of the corrected trajectory; and providing the determined assistant torque to the support frame.Type: GrantFiled: January 7, 2015Date of Patent: June 26, 2018Assignee: Samsung Electronics Co., Ltd.Inventors: Kee Hong Seo, Ju Suk Lee

Patent number: 9980873Abstract: A leg support exoskeleton is strapped on as wearable device to support its user during squatting. The exoskeleton includes a knee joint connected to a first line and a second link, which is configured to allow flexion and extension motion between the first link and the second link. A force generator has a first end that is rotatably connected to the first link. A constraining mechanism is connected to the second link and has at least two operational positions. In a first operational position, the second end of the force generator engages the constraining mechanism, where the first link and the second link flex relative to each other. In a second operational position, the second end of the force generator does not engage the constraining mechanism; the first link and the second link are free to flex and extend relative to each other.Type: GrantFiled: July 12, 2017Date of Patent: May 29, 2018Assignee: U.S. Bionics, Inc.Inventors: Wayne Tung, Minerva Pillai, Homayoon Kazerooni
