Patent number: 11744720Abstract: An approximation method and system are provided for more quickly controlling a prosthetic or other device by reducing computational processing time in a muscle model that can be used to control the prosthetic. For a given muscle, the approximation method can quickly compute polynomial structures for a muscle length and for each associated moment arms, which may be used to generate a torque for a joint position of a physics model. The physics model, in turn, produces a next joint position and velocity data for driving a prosthetic. The approximation method expands the polynomial structures as long as expansion is possible and sufficiently beneficial. The computations can be performed quickly by expanding the polynomial structures in a way that constrains the muscle length polynomial to the moment arm polynomial structures, and vice versa.Type: GrantFiled: September 18, 2018Date of Patent: September 5, 2023Assignee: WEST VIRGINIA UNIVERSITYInventors: Anton Sobinov, Sergiy Yakovenko, Valeriya Gritsenko, Russell Hardesty, Matthew Boots

Patent number: 11690736Abstract: A rotary drive member drives a driven member. A ring surrounding the driven member has two cam recesses containing lock members between cam surfaces of cam recesses and the ring. Each recess accommodates an associated lock member at different locations where the recess is shallower. Driving the driven member is permitted in a given rotation relative to the ring, but each lock member inhibits rotation of the driven member in the opposite sense. The recesses extend in opposite directions. Coupling between the driven members is free-play whereby reversal in the rotation disengages members and reengages. Protuberances extending into cam recesses retain a lock member associated with one recess at the deeper location permitting movement of the other lock member towards the shallower location. Upon reversal of the rotation, the protuberances retain another lock member at the deeper location permitting movement of one lock member.Type: GrantFiled: November 18, 2020Date of Patent: July 4, 2023Assignee: Hugh Steeper LimitedInventors: Garry Marsh, James Sykes

Patent number: 11612504Abstract: The present disclosure is directed to a compact wrist rotator and flexor mechanism for use with a prosthetic hand. The wrist rotator and flexor uses a set of motors to provide a driven mechanism having two degrees of freedom, a wrist rotation and a wrist flexion. The rotator uses a motor with an inverted shaft gearbox combined with a worm gear and a face gear transmission to generate continuous and non-backdrivable rotation. The rotator is integrated into a flexor that uses a lead screw acting as a linear actuator to provide strong non-backdrivable flexion and extension. Due to the arrangement of the drives, the resulting wrist rotator and flexor mechanism has a low and compact profile.Type: GrantFiled: December 14, 2020Date of Patent: March 28, 2023Assignee: Rehabilitation Institute of ChicagoInventors: Todd Kuiken, Frank Ursetta

Patent number: 11554029Abstract: This disclosure provides systems, apparatuses, and devices for a prosthetic digit usable with persons with amputations at or proximal to the metacarpophalangeal joint. The device restores prehension in a person with missing fingers or thumb by providing opposition to forces in the extension direction via a spring-loaded pawl and locking rack ratchet mechanism, thereby allowing an individual to manipulate or stabilize objects. The digit may be spring-loaded in the extension direction by a torsion spring or other biasing member. The pawl may be automatically disengaged from the rack when the digit reaches full flexion, and the full flexion disengage stop may be adjustable. The pawl may be automatically engaged with the rack when the digit reaches full extension, and the extension stop may be adjustable. The pawl may contain a lateral feature that creates interference with the anchoring linkage under load and limits deflection of the structure.Type: GrantFiled: September 22, 2020Date of Patent: January 17, 2023Assignee: RCM Enterprise L.L.C.Inventors: Erich Theodore Griebling, Catherine Rocille Treadwell, Bradley Arthur Crittenden
