摘要： Various aspects of the present disclosure characterize apparatuses and/or methods as may be implemented with a variety of prosthetic components and applications. As may be consistent with one or more embodiments described herein, respective manipulators are operable and/or operate to manipulate a prosthetic foot component about respective (e.g., separate) axes. A sensor circuit senses movement characteristics of the prosthetic foot component (e.g., movement, surroundings, and/or load applied due to movement). The manipulators operate with the sensor circuit to manipulate the prosthetic foot component about the axes in response to the sensed movement characteristics indicating that the prosthetic foot component is elevated over a surface.

摘要： A link extends between a distal member and a proximal member of a wearable device, such as an exoskeleton, orthosis or prosthesis for a human lower limb. One or other of the distal member and the proximal member includes a crossing member. The link extends from the crossing member of the distal member or the proximal member, to the other of the distal member or the proximal member. Actuation of the link translates to a force at the distal or proximal member that is normal to a major longitudinal axis extending through the distal and proximal members. In one embodiment, a sliding link of a device configured for use with a human joint tracks two degrees of freedom of the joint.

摘要： A vacuum pump may be used to attach a prosthetic and/or orthotic device to a residual limb. The vacuum pump may be in line below a socket of a residual limb. The socket may be a portion of the prosthesis that accepts the residual limb. The vacuum pump may generate a vacuum condition between the prosthesis and the residual limb. Generally, a vacuum condition may be generated between a socket and the residual limb. The residual limb may be covered with a sock, elastomeric liner, or sheath covering the limb. The vacuum condition may positively attach the prosthesis to the residual limb without the need for straps, retaining pins, or suction type vacuum which do not use a vacuum pump.

摘要： An orthopedic joint device having a lower leg part, a foot part that is arranged on the lower leg part about a swivel axis such that it can be swivelled, at least a first energy store, and a coupling element. The coupling element can be brought into a coupling position, in which a swivelling of the foot part relative to the lower leg part about the swivel axis in a plantar flexion direction leads to an increase in the amount of energy stored in the first energy store, and a de-coupling position. The orthopedic joint device also has at least one release element, which can be brought into a release position and a locked position. The energy stored in the first energy store can be released by bringing the release element into the release position.

摘要： A system for joining a limb liner to a prosthesis. The prosthesis has a socket that is joined to the remainder of the prosthesis using a hub assembly. The hub assembly includes a first hub and a second hub. The first hub is disposed within the interior of the socket. The second hub is disposed outside the interior of the socket. An air conduit extends through the hub assembly that enables air to be drawn into the socket and/or vented from the socket. An inflatable interface is disposed within the socket. The inflatable interface receives air through the air conduit in the hub assembly. The inflatable interface is capable of filling any gaps that may exist between a limb liner being worn by an amputee and the socket.

摘要： A prosthetic system includes first and second parts rotatable relative to one another about a joint. The first and second parts are adapted to form at least part of a weight bearing connection between a prosthetic foot and a socket. A pump system includes a pump mechanism operatively connected to the first and second parts. Rotation of the first part and/or the second part about the joint moves the pump mechanism between an original configuration in which the volume of a fluid chamber defined by the pump mechanism is zero or near-zero, and an expanded configuration in which the volume of the fluid chamber is increased.

摘要： An asymmetric linear actuator is provided which integrates a hydraulic dissipater and an electric motor and power screw which generates small forces. The actuator is configured so that an electric motor drives a power screw which drives a rod through a cylinder to provide linear actuation. The cylinder is fluid-filled and incorporates a piston that separates the cylinder into a first and second fluid chamber which are filled with a first and second volume of working fluid. Movement of the piston and rod assembly results in fluid movement between the first and second volumes of working fluid and through the fluidic restriction. The fluidic restriction can be proportionally controllable via an electric motor which enables controllable power dissipation via control of the fluidic restriction motor and controllable power generation via control of the power screw motor.

摘要： Knee orthoses or prostheses can be used to automatically, when appropriate, initiate a stand-up sequence based on the position of a person's knee with respect to the person's ankle while the person is in a seated position. When the knee is moved to a position that is forward of the ankle, at least one actuator of the orthosis or prosthesis is actuated to help raise the person from the seated position to a standing position.

摘要： Systems and methods for providing torque to an assistive device are disclosed. In an embodiment, an apparatus comprises a material arranged to define a volume of space. The material may comprise a flexible portion and having a first surface and a second surface. The material may have a first position, in which the material is bent along the flexible portion and the first surface contacts the second surface. When the material is in the first position, an increase in pressure to the space creates a force between the first surface and the second surface. The material transitions from the first position to a second position in response to the force between the first surface and the second surface. The apparatus may be attached to an assistive device or other machine, such as an orthosis or prosthesis, in order to provide a torque.
