Abstract: A tool-holding arm includes a plurality of links and a tool coupling that removably secures a tool to the tool-holding arm. A first fluid spring provides a gravity-counteracting force to the tool-holding arm. A locking mechanism selectively locks the first fluid spring. An adjustment mechanism selectively adjusts an amount of the gravity-counteracting force provided by the first fluid spring.

Abstract: An exoskeleton includes an arm brace coupled to an arm of a wearer and a tensile member connected to the arm brace. An actuator exerts a pulling force on the tensile member. The pulling force reduces a length of the tensile member between the arm brace and the actuator and causes the arm of the wearer to bend at an elbow.

Abstract: An exoskeleton includes a first link that pivots in a transverse plane about a first vertical axis and a second link that pivots in a transverse plane about a second vertical axis. The second link is coupled to the first link. An arm support assembly is coupled to the second link and pivots about a horizontal axis. The arm support assembly includes a spring that generates an assistive torque that counteracts gravity. The arm support assembly provides the assistive torque to an arm of a wearer to support the arm of the wearer. The arm support assembly further includes a cam profile and a cam follower. Contact between the spring, cam follower and cam profile determines an amount of the assistive force provided by the arm support assembly. A cuff is coupled to the arm support assembly and the arm of the wearer.

Abstract: A tool arm mount couples a tool arm to an aerial work platform. The tool arm mount includes a first mounting hook that hangs on a first rail of the aerial work platform and a second mounting hook that hangs on a second rail of the aerial work platform. The first mounting hook defines a first channel in which the first rail is received, and the second mounting hook defines a second channel in which the second rail is received. The first and second mounting hooks are coupled to a spine of the tool arm mount. The tool arm mount also includes a first lock that locks the first mounting hook to the first rail.

Abstract: An exoskeleton includes strapping for coupling the exoskeleton to a wearer. The exoskeleton also includes a hip structure, a thigh link rotatably connected to the hip structure and a shank link rotatably connected to the thigh link. The weight of the exoskeleton is transferred to a surface on which the exoskeleton is standing through the hip structure, the thigh link and the shank link. An arm brace supports an arm of the wearer, and a telescopic link is rotatably connected to the arm brace. An energy storage device delivers power to a tool through a conduit, and a conduit-energy storage device coupling connects the conduit to the energy storage device.

Abstract: An exoskeleton device includes a first brace coupled to a first portion of a wearer of the exoskeleton device and a second brace coupled to a second portion of the wearer. A first joint connects the first and second braces and allows relative movement between the first and second braces. A first brake is controllable between an unactuated state and a plurality of actuated states, and the first brake impedes relative movement between the first and second braces at the first joint while the first brake is in one of the plurality of actuated states. A manual actuator is selectively used by the wearer during relative movement between the first and second braces. Use of the actuator causes the first brake to enter one of the plurality of actuated states such that relative movement between the first and second braces is impeded at the first joint.

A cuff is coupled to the arm support assembly and the arm of the wearer.

Abstract: A three-dimensional surface scan of an exoskeleton wearer is performed to generate three-dimensional surface data, and a three-dimensional surface model of the exoskeleton wearer is generated from the three-dimensional surface scan data. A three-dimensional exoskeleton model is generated from the three-dimensional surface model. At least one three-dimensional exoskeleton component is printed from the three-dimensional exoskeleton model, and a custom-fit exoskeleton is assembled using the at least one three-dimensional exoskeleton component.

Abstract: A powered exoskeleton configured to be coupled to lower limbs of a person is controlled to impart a movement desired by the person. The intent of the person is determined by a controller based on monitoring at least one of: positional changes in an arm portion of the person, positional changes in a head of the person, an orientation of a walking aid employed by the person, a contact force between a walking aid employed by the person and a support surface, a force imparted by the person on the walking aid, a force imparted by the person on the walking aid, a relative orientation of the exoskeleton, moveable components of the exoskeleton and the person, and relative velocities between the exoskeleton, moveable components of the exoskeleton and the person.

Abstract: An apparatus for transferring material winding between spools. The apparatus includes spindels for positioning first and second spools in a co-planar arrangement with parallel axes of rotation. With the material initially secured to the base of a first spool with tape, a winding mechanism is energized to turn the spools. When the first spool is filled, a first sheave directs the incoming material to the second spool which is rotated at the rate of material supply. A tape applicator is then directed to apply a section of tape over the material, pressing it against the base of the second spool. A small wire is included on the base of the tape being applied. The applicator force on the wire against the material is designed to be sufficient to sever the material, separating the material on the first spool from the material being wound on the second.
