  • Patent number: 11890209
    Abstract: A flexible inner socket is fabricated by forming a pre-socket. The pre-socket includes a body formed with an opening and an enclosed end. The enclosed end is opposite to the opening. The body of the pre-socket has an outer circumference that is smaller than the inner circumference of the rigid prosthetic socket. Different portions of the body may have different thicknesses. The preform socket is heated. After the heating, the flexible inner socket is formed by molding the pre-socket onto the inner surface of the rigid prosthetic socket to form the flexible inner socket. The inner circumference of the rigid prosthetic socket is reduced by a thickness of the flexible inner socket when the flexible inner socket is attached to the inner surface of the rigid prosthetic socket. An opening of the flexible inner socket may be trimmed after the formation to fit contours of an opening of the rigid prosthetic socket.

  • Patent number: 11801154
    Abstract: An adjustable socket system includes first and second shell components and first and second longitudinal supports connected to a base. The socket system is movable between an open configuration to loosen the fit of the socket system, and a closed configuration to secure the fit of the socket system on residual limb received therein. A tightening system includes a tensioning unit having a handle defining a moment arm rotatable about a rotation axis, and a tensioning element operatively coupled to the handle via a movable connection point located and protected between the first shell component and the first support and to the shell components via a control point.

  • Patent number: 11744720
    Abstract: 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.

  • Patent number: 11690736
    Abstract: 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.

The at least one electrode pair is designed to capture at least a first muscle-related signal using a first measurement frequency and a second muscle-related signal using a second measurement frequency. The at least one evaluation unit evaluates a phase of the first signal and a phase of the second signal. The muscle-related signals can be bioimpedance signals. The system makes it possible to distinguish between muscle contractions and interfering signals.
