Abstract: The invention relates to an orthopedic appliance which is designed to support the weight of a patient and comprises a power supply device for an electrical consumer. The aim of the invention is to be able to convert the kinetic energy introduced into the appliance into electrical energy. To this end, the power supply device comprises a stack (7) of piezoelectric ceramic elements, and the force of the weight is introduced into the stack (7) by means of a force transmission system.

Abstract: The invention relates to a center of gravity control display system for measuring the human body and/or prosthetic or orthotic fittings in their positions relative to the human body. According to the invention, this system consists of a measuring plate (1) for determining center of gravity (4) projected in the plane of measuring plate (1), of a person standing on measuring plate (1), and of a projection device (2) for projecting a perpendicular measuring line onto the body of said person, with measuring plate (1) being provided with pressure sensors (3) connected with one another by a circuit, said sensors delivering an electrical signal defining the determined center of gravity position, said signal controlling a drive that displaces an optical system in a plane parallel to that of measuring plate (1), said system projecting a light beam (19) as a vertical measuring line that defines a plane in which center of gravity (4) of the person being measured lies.
