Patent number: 11938074Abstract: A neck supporting exoskeleton is configured to be worn by a person to support the person's head during backward extension motions of the person's neck. The neck supporting exoskeleton may comprise a torso frame configured to be coupled to the person's torso, a head pillow configured to contact the rear portion of the person's head during backward extension motions of the person's neck, a linkage allowing for relative motion between the head pillow and the torso frame in the sagittal plane of the person, and an actuator configured to impose a supporting force onto the head pillow. When the person's neck extension angle increases beyond an engagement angle, the actuator causes the linkage to impose a supporting force onto the head pillow resisting the backward extension motion of the head pillow and the person's head relative to the torso frame thereby providing a support for the person's head.Type: GrantFiled: October 18, 2019Date of Patent: March 26, 2024Assignees: The Regents of the University of California, suitX, Inc.Inventors: Logan Van Engelhoven, Homayoon Kazerooni, James Ren, Wayne Yi-Wei Tung, Valantyn Koziak

Publication number: 20230286133Abstract: Described herein is an arm supporting exoskeleton including a proximal link, a distal link, a torque generator, and a bracket. The distal link is configured to rotate relative to the proximal link about a first rotational axis forming a first angle between the proximal link and the distal link. The torque generator is configured to provide a torque profile between the proximal link and the distal link as a function of the first angle, thereby producing a supporting force onto the upper arm of the person. The bracket is coupled to one of the proximal link or the distal link. A location of the bracket is adjustable to adjust an effective length of the torque generator to adjust an amplitude of the torque profile provided by the torque generator thereby adjusting the supporting force onto the upper arm of the person.Type: ApplicationFiled: May 18, 2023Publication date: September 14, 2023Inventors: Logan VAN ENGELHOVEN, Homayoon KAZEROONI

Publication number: 20230201065Abstract: A human interface device is configured to be coupled to a trunk of a person and comprises a frame, a fabric coupled to said frame configurable to be under tensile forces, and a belt configured to be coupled to two side edges of said frame wherein when said belt is worn by said person, an area of said fabric will be pushed against the person’s lower back conforming to the shape of the lower back of said person. In operation when said human interface device is worn by said person, the weight of any load coupled to or supported by said frame will be partially supported by the friction force between the area of said fabric which is pushed against the person’s lower back, and the person’s lower back allowing said person to carry said load.Type: ApplicationFiled: March 2, 2023Publication date: June 29, 2023Applicant: suitX, Inc.Inventors: James Hatch, Logan Van Engelhoven, Homayoon Kazerooni, Valantyn Joseph Sean Koziak, Minerva Pillai, John Jow Kuwata

Patent number: 11654546Abstract: Described herein is an arm supporting exoskeleton, comprising an arm link mechanism. The arm link mechanism comprises a proximal link, a distal link, an arm coupler, and a variable force generator. The distal link is rotatable relative to the proximal link. The arm coupler is adapted to couple an upper arm of a person to the distal link. The variable force generator comprises a first spring and a second spring, configured to create a torque between the proximal link and the distal link. In the first force mode, the variable force generator exhibits a first stiffness rate defined by the first spring that supports the upper arm of the person against gravity forces and. In the second force mode, the variable force generator exhibits a second stiffness rate defined by the first spring and the second spring that supports the upper arm of the person against the gravity forces.Type: GrantFiled: April 2, 2021Date of Patent: May 23, 2023Assignee: The Regents of the University of CaliforniaInventors: Logan Van Engelhoven, Homayoon Kazerooni
