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 catalytic device that can increase the durability of a catalyst support with holes is provided. A flat plate and a corrugated plate have a plurality of holes, a joint area between the flat plate and the corrugated plate is provided in a first upstream area including one end of a catalyst support, and a joint area between the catalyst support and an outer cylinder is provided in a second upstream area that includes the first upstream area and is wider than the first upstream area in the direction of an axis.
