Abstract: A passive artificial knee comprises first and second links rotatably coupled at a knee joint, a passive compressive force generator rotatably coupled to the second link, and a release mechanism coupled to the first link. When a relative angle of the first and second links is less than a toggle angle, the release mechanism locks in a first operational mode, and the force generator compresses, resisting the flexing of the second link relative to the first link. When the relative angle is larger than the toggle angle, the force generator decompresses and encourages the flexion of said second link relative to said first link. When the force generator is substantially extended and said compressive force is substantially small, the release mechanism moves into a second operational mode, wherein the force generator neither resists nor encourages the extension and flexion of said second link from said first link.

Abstract: Systems, methods, and apparatus provide artificial knees. Artificial knees include a thigh link configured to move in unison with a thigh of the person, a shank link configured to be rotatably coupled to said thigh link, and a compression spring rotatably coupled to the thigh link and coupled to a second end of shank link with a second end of the compression spring. During a first range of motion, the compression spring is configured to provide an extension torque between the thigh link and the shank link causing said artificial knee to resist flexion. After said first range of motion, the compression spring is configured to provide a flexion torque between the thigh link and the shank link encouraging said artificial knee to flex resulting in toe clearance during the swing phase. During the swing phase, the compression spring provides no torque between the thigh link and the shank link.

Abstract: A wearable apparatus comprises a passive artificial knee that comprises first and second links coupled at a knee joint, a passive compressive force generator coupled to the second link, and a release mechanism coupled to the first link. When an angle of the first and second links is less than a toggle angle, the release mechanism locks in a first operational mode, and the force generator compresses, resisting flexing of the second link. When the angle is larger than the toggle angle, the force generator decompresses and encourages flexion of said second link. When the force generator is extended and said compressive force is small, the release mechanism moves into a second operational mode, wherein the force generator neither resists nor encourages extension and flexion of said second link from said first link. The wearable apparatus comprises an exoskeleton trunk configured to couple to an upper body of a user.
