The deposition apparatus (106) receives the at least one elastomeric material from the first and second dispensing systems (102, 104). The deposition apparatus (106) may comprise heating and/or cooling elements (160), a sonic vibration module (164), and/or a pneumatic suck-back valve (162). The deposition substrate (130) is configured to rotate and/or translate relative to the deposition apparatus (106). The system (100) comprises a controller configured to control the deposition.

A progressive strap assembly includes an elongate, inelastic body having first and second ends, and an elastic body having first and second ends, the first end of the elastic body anchored to the second end of the inelastic body. The elastic body is arranged to stretch a plurality of lengths and has a maximum stretchable length. A tension limiter is connected to the first and second ends of the elastic body and is arranged to inhibit a predetermined stretchable length of the elastic body short of the maximum stretchable length.

An adjustable socket system includes a socket frame having a proximal area, a distal area opposite the proximal area, a first component arranged along a first side of the socket system, and a second component arranged along a second side of the socket system. The first component is connected to the second component. A tubular insert is arranged on an interior of at least the proximal area of the socket frame. The tubular insert forms an interior surface of the socket system. At least one tensioning element operatively connects the tubular insert to the first and/or second components. At least one tensioner is attached to the at least one tensioning element that selectively tensions the tensioning element to adjust a circumference of at least one area of the socket system.
An ankle support (10) includes a sleeve (12) and a heel strap (34) that offers comfortable and secure heel fit. The ankle support (10) has a versatile strap system (14) that can be easily configured for different indications and forms of restriction. The strap system (14) accounts for the anatomy of the ankle by offering stretch where needed to provide effective motion control while balancing comfort. The strap system (14) has segments lacking elasticity or stretch to stably secure the strap system about a user's ankle while accommodating the anatomy of the ankle and minimizing migration and discomfort.

A prosthesis or an orthosis and method of operating the same. The prosthesis or orthosis comprising a moveable component, a motor operable to move the component, wherein the motor has at least one operating parameter, the application of which to the motor results in the component having at least one operating condition; and an electronic device operable to: determine at least one operating parameter of the motor and determine at least one instantaneous operating condition of the component from a predetermined operating profile of the motor and component and the determined at least one operating parameter of the motor, the predetermined operating profile of the motor and component being based on one or more operating parameter inputs to the motor and one or more resulting operating condition outputs of the component.
An adjustable prosthetic socket includes proximal and distal ends and an axis extending between the proximal and distal ends. A distal base is adapted to support a distal portion of a residual limb and is located at the distal end of the socket. First and second spines extend upward from the distal base that define at least part of a circumference of the socket about the axis. A proximal support is connected to the second spine and arranged to distribute pressure from the second spine over a portion of the residual limb. A tensioning system is operatively connected to the first and second spines and arranged to selectively adjust the circumference of the socket. The tensioning system includes a dial tensioner connected to the first spine.
