The invention relates to an orthopedic device with an energy storage device 2 that comprises at least one cylinder 4, in which a first cylinder chamber 6, a second cylinder chamber 8, which is fluidically connected to the first cylinder chamber 6 by at least one fluid line 14, and a piston 10 are located, wherein the piston 10 is arranged relative to the cylinder 4 such that it can be displaced in such a way that by displacing the piston 4, an operating medium, which is a fluid, is conveyed through the at least one fluid line 14 from one cylinder chamber 6, 8 into the other cylinder chamber 8, 6, wherein the energy storage device 2 has at least one compensation volume 24, which is fluidically connected to the fluid line 14 via a fluid connection 22, and a first controllable valve 26, by means of which the fluid connection 22 can be opened and closed.

Assistive movement devices and methods therefor are provided that are capable of redirecting loads from an individual's foot to hip when an individual is recovering from an injury at or below the knee. The devices include a frame assembly comprising an upper member, a lower member, and a joint therebetween. An upper attachment is secured to the upper member and is configured to be secured to the thigh of the individual's leg, and a lower attachment is secured to the lower member or the base and is configured to be secured to a portion of the leg below a knee thereof. A base is secured to the lower member and is configured to support a foot of the leg, and the device adjustably redirects at least a portion of a load resulting from the individual standing and walking from the base to the upper attachment.

A prosthetic device includes a prosthesis wall, at least one display carried by the prosthesis wall in spaced-apart relationship to the at least one display and interfacing with the at least one display, the control module adapted to present at least one image on the at least one display.

Provided is an electric transmission device that is provided at relatively rotating parts of a mechanical apparatus. The electric transmission device (E) includes a pair of magnetic elements (1A, 1B) relatively rotatable about the same axis (O). The magnetic elements (1A, 1B) each includes a core (2A, 2B) and a coil (3A, 3B) having a conductive wire. One of the coil (3A) and the coil (3B) is located at an inner side of the other coil in a radial direction, and the coils (3A and 3B) are magnetically coupled to each other. Each bobbin (4A, 4B) includes a cylinder (4aA, 4aB) and a dis-shaped flange (4bA, 4bB). The flanges (4bA, 4bB) are slidably in contact with each other at contact surfaces (10a, 11a) thereof in the axial direction.

A method and apparatus for enhancing the operation of leg prothesis is provided. The apparatus includes a cable configured to be attached to the leg prosthesis worn by a subject to move through a plurality of gait phases. The apparatus also includes a module configured to be mounted to the leg prosthesis. The module includes a tension spring configured to engage the cable to maintain tension in the cable. The module also includes a locking mechanism configured to lock a position of the tension spring and maintain a length of the cable defined between the module and the leg prosthesis during at least one first gait phase of the plurality of gait phases. The locking mechanism is further configured to unlock the position of the tension spring to permit variation of the length of the cable during at least one second gait phase of the plurality of gait phases.

A lower limb prosthesis system and a method of controlling the prosthesis system to replace a missing lower extremity of an individual and perform a gait cycle are disclosed. The prosthesis system has a controller, one or more sensors, a prosthetic foot, and a movable ankle joint member coupled to the prosthetic foot. The movable ankle joint member comprises a hydraulic damping system that provides the ankle joint member damping resistance. The controller varies the damping resistance by providing volumetric flow control to the hydraulic damping system based on sensor data. In one embodiment, the hydraulic damping system comprises a hydraulic piston cylinder assembly, hydraulic fluid, and a valve to regulate the fluid. In one embodiment, the controller alters the damping resistance by modulating the valve to vary the hydraulic fluid flow within the hydraulic piston cylinder assembly of the movable ankle joint member based on sensor data.

The adjustable prosthetic leg, which is connected between a thigh and an artificial foot, has a controller, a connecting mechanism, a hydraulic unit, and a shell. The connecting mechanism and the hydraulic unit are pivotally connected to the controller, and the shell is pivotally connected to the hydraulic unit. The connecting mechanism extends into a hydraulic cylinder of the hydraulic unit. The hydraulic cylinder is in communication with a reserve hydraulic cylinder and a brake hydraulic cylinder of the hydraulic unit. The prosthetic leg allows a user to climb up or go down the stairs and walk on uneven ground easily without falling down.
