摘要： A dynamic variable geometry fitting system with fluid-filled bladders and automatically regulating their volumes to provide a continuously secure fit. This system can vary volume continuously to accommodate natural variation in an amputee's residuum. It makes reliable suction retention of a prosthesis easier for the prosthetist to achieve while reducing the potential for tissue lesions. By maintaining a continuous, secure fit, the amputee's sense of confidence and willingness to use the prosthesis increases.

摘要： A retraction device for a disc brake caliper is provided having brake pads actuated by hydraulic fluid. The device includes a housing having a bore that defines an axis. A piston is disposed within the bore and is movable along the axis between applied and retracted positions. The piston includes an apply end adapted to coact with the brake pads in the applied position and a hydraulic end opposite the apply end. A hydraulic chamber is defined by the bore and the hydraulic end and contains hydraulic fluid for generating a brake pressure to achieve the applied position. An annular groove is formed in the bore adjacent to the piston, and the annular groove includes a forward angled surface. A resilient seal is disposed within the annular groove for retracting the piston from the applied position to the retracted position. The resilient seal has a first side adjacent the forward angled surface and a second side opposite the first side. A pressure mechanism is arranged adjacent to the second side and is in communication with the hydraulic chamber for generating a retaining pressure to retain the resilient seal against the forward angled surface in response to the brake pressure. The pressure mechanism releases the retaining pressure to permit the resilient seal to retract the piston when below the brake pressure.
