Abstract: A method for controlling the standing-phase damping of an artificial knee joint comprising an upper part and a lower part which are secured together in a pivotal manner about a pivot axis, a resistance unit which is arranged between the upper part and the lower part and has an adjustment device via which the damping resistance can be modified, and a control unit which is coupled to the adjustment device and which is connected to at least one sensor. The adjustment is carried out on the basis of sensor data, and the knee angle is detected by the at least one sensor during the standing-phase inflexion up to the terminal standing phase. The flexion damping is increased to a level above an initial flexion damping in order to prevent a further inflexion upon reaching a specified maximum knee angle.

Abstract: A method for controlling a damping modification in an artificial knee joint of an orthosis, an exoskeleton, or a prosthesis. The artificial knee joint has an upper part pivotally connected to a lower part A resistance unit is secured between the upper part and the lower part in order to provide a resistance against a flexion or extension The resistance unit is paired with an adjustment device to modify the resistance when a sensor signal of a control unit paired with the adjustment device activates the adjustment device. The flexion resistance is reduced for the swing phase. A curve of at least one load characteristic is detected when walking or standing; a maximum of the load characteristic curve when standing is ascertained; and the flexion damping is reduced to a swing-phase damping level during the standing phase when a threshold of the load characteristic below a maximum is reached.

Abstract: A method for operating an electric motor when at a rotational speed below or above a predetermined limit value. The method involves operating an electric motor that has a stator and a rotor, wherein the stator or the rotor has at least three segments each having at least one electromagnetic element. The method includes simultaneously de-energizing all electromagnetic elements of all segments while the rotor rotates, measuring an electrical quantity induced in the electromagnetic elements, in particular an induced voltage, for each segment, and determining a rotor position of the rotor in relation to the stator from the measured electrical quantities. An electrical current can be supplied to the electromagnetic elements such that a segment magnetic field is formed to provide a segment torque to the rotor. The intensity of the electrical current depends on a segment position of the rotor in relation to the segment.
