Abstract: A trunk supporting exoskeleton comprises: a supporting trunk; thigh links configured to move in unison with a wearer's thighs; and first and second torque generators located on both left and right halves of the wearer substantially close to the wearer's hip. The torque generators couple the supporting trunk to the thigh links, and generate torque between the thigh links and the supporting trunk. When the wearer bends forward such that a predetermined portion of the supporting trunk passes beyond a predetermined angle from vertical, a torque generator(s) imposes a resisting torque between the supporting trunk and the thigh link(s), causing the supporting trunk to impose a force against the wearer's trunk, and the thigh link(s) to impose a force onto the wearer's thigh. When the predetermined portion does not pass beyond the predetermined angle, the torque generators impose no resisting torques between said supporting trunk and respective thigh links.

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.

Abstract: A coupling device couples a walker to a torso orthosis which is coupled to a person. The coupling device includes an orthosis coupling member coupled to said torso orthosis, a walker coupling member coupled to said walker, and a mechanism coupled to the orthosis coupling member from its first end and to the walker coupling member from its second end. The mechanism constrains said orthosis coupling member to move along a free line. The torso orthosis is worn by the person and said coupling device is coupled to both said walker and said torso orthosis. The person may be walking along a moving direction not parallel with said free line. The mechanism forces said walker and torso orthosis to move along said moving direction and allows said torso orthosis to move freely along said free line when said moving direction is not parallel with said free line.

Abstract: An arm supporting exoskeleton comprises a shoulder base coupled to an arm link mechanism. The arm link mechanism comprises a proximal link and a distal link configured to rotate relative to each other about a rotating joint; at least one arm-coupler adapted to couple a user's arm to the distal link; a tensile force generator coupled to the proximal link and the distal link, and providing a torque to flex the distal link relative to the proximal link; and a protrusion located substantially at the rotating joint. When the distal link extends past a toggle angle, the protrusion constrains the tensile force generator, and the torque provided by the tensile force generator remains substantially small, When the protrusion does not constrain the tensile force generator, the torque tends to flex the distal link relative to the proximal link, thereby reducing human shoulder forces and torques required to raise the arm.

Abstract: Systems, methods, and apparatus provide an artificial knee. Such artificial knees may include a thigh link configured to move in unison with a thigh of the person, a shank link configured to be rotatably coupled to the thigh link, and a compression spring rotatably coupled to the thigh link at a first end and coupled to the shank link at a second end. The compression spring is configured to provide an extension torque between the thigh link and the shank link during a first range of motion of the thigh link and the shank link relative to each other. The compression spring is configured to provide a flexion torque between the thigh link and the shank link during a second range of motion of the thigh link and the shank link relative to each other.
