Patent number: 11033406Abstract: A method for controlling the standing-phase damping of an artificial knee joint comprising an upper part and a lower part which are secured together in a pivotal manner about a pivot axis, a resistance unit which is arranged between the upper part and the lower part and has an adjustment device via which the damping resistance can be modified, and a control unit which is coupled to the adjustment device and which is connected to at least one sensor. The adjustment is carried out on the basis of sensor data, and the knee angle is detected by the at least one sensor during the standing-phase inflexion up to the terminal standing phase. The flexion damping is increased to a level above an initial flexion damping in order to prevent a further inflexion upon reaching a specified maximum knee angle.Type: GrantFiled: April 15, 2016Date of Patent: June 15, 2021Assignee: OTTO BOCK HEALTHCARE PRODUCTS GMBHInventors: Dirk Seifert, Sven Zarling

Patent number: 10918335Abstract: A sensing module is disclosed in the present invention and includes a body attaching member, a base module, a transmission member and a first sensor. The body attaching member is attached to a human limb and disposed on the base module. The transmission member is coupled to and moved with the body attaching member. The first sensor is disposed on a side of the body attaching member and separate from the body attaching member. When the body attaching member is driven to move along a direction by the human limb, the body attaching member drives the transmission member to activate the first sensor to generate a first signal. Since the first sensor is separate from the human limb, the first sensor is not affected by muscle swelling and skin friction during movement. Accordingly, the actuating module is able to drive the exoskeleton member more precisely.Type: GrantFiled: June 6, 2018Date of Patent: February 16, 2021Inventor: Zhong-Jheng Lin

Patent number: 10888487Abstract: A grasp assist system includes a glove having a glove palm and fingers, with the glove worn on a user's hand. A sensor measures flexion of the glove fingers, and thus a change of position and/or attitude of the fingers is determined. Finger saddles at least partially surround a phalange of a respective one of the user's fingers. The system uses one or more tendon actuators to pull on flexible tendons. Each tendon connects to a respective finger saddle. A controller is in communication with the actuators and sensor(s). The glove may use feedback from optional contact sensors to adjust tension, and may have a built-in restorative force. In executing a control method, the controller selectively applies tension to the tendons in response to finger flexion, via the tendon actuators, at a level sufficient for moving the user's fingers when the user executes a hand maneuver.Type: GrantFiled: April 5, 2018Date of Patent: January 12, 2021Assignee: United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Jonathan M.
