An electromechanical brake booster having a plunger rod for connecting a brake pedal lever to a brake master cylinder, a gear motor, which is coupled with the plunger rod, and a control device for driving the gear motor. A pedal force variable representing the pedal force and a plunger rod motion variable representing the motion of the plunger rod are supplied to the control device as input variables. The control device is configured to determine a setpoint return velocity for the plunger rod with the aid of the plunger rod motion variable and an actual return velocity for the plunger rod and the pedal force variable from the setpoint return velocity and to generate an activation signal for the gear motor. This makes it possible to improve the brake release behavior and to reduce high Bernoulli forces at the end stop for the starting position of the brake pedal lever.

A method for generating an optical frequency comb with a defined number of frequency comb lines with an adjustable spacing therebetween includes generating an input frequency comb comprising a multiplicity of input frequency comb lines with a light source. Individual frequency comb lines having an identical frequency spacing are filtered out of the multiplicity of input frequency comb lines so as to obtain filtered frequency comb lines. A first modulating of the filtered frequency comb lines is performed at a first modulation frequency so as to generate first sideband lines. The first sideband lines are generated by the first modulating so that the filtered frequency comb lines and the first sideband lines have an identical frequency spacing.

A compression stocking () made of a knit or woven elastic fabric provided with a compression body () which can be attached to the compression stocking () such that the compression body is positioned at a knee joint (). The compression stocking () of the invention can be used, for example, after surgery in the area of the knee joint (). To get rid of the wound secretion, blood and tissue fluid that occurs during surgery from the soft tissue surrounding the joint, a defined pressure is applied by the compression stocking () and the compression body () to the soft tissue of the knee joint (). To this end, the compression body () has a recess () to accommodate the patella of the knee joint (). The recess () and the compression body () each have an elliptical shape, which is approximately adapted to the shape of the patella, i.e., the joint soft tissue. To accommodate the wound suture and associated wound clamps, the compression body () has a groove-shaped recess () on the surface facing the soft tissue of the knee joint ().

The invention relates to a device for detecting the position of a magnet which is positioned so that it is moveable ( ) to produce a magnetic field ( ) through a ferromagnetic wall ( ), a magnetic field sensor ( ) being situated in front of said wall. When said magnet ( ) is moved in relation to said wall ( ), the lines ( ) of the field build up a useful flux ( ) which progresses in said wall ( ). Said useful flux has magnetic remanence ( ) which is retained after the magnet ( ) has passed by, is aligned along the movement axis of the magnet ( ) in accordance with the polarity, and builds up a fringing flux ( ) to the front side of the wall ( ) where the magnetic field sensor ( ) is positioned. Outside of said wall, the fringing flux ( ) is opposed and is aligned with the useful flux (6). The magnetic field sensor is a magnetic field sensor element ( ) located at a short distance from the wall ( ) and detects the field direction of the fringing flux ( ); when the magnet ( ) passes by, the fringing flux is superposed by the field ( ) of the magnet ( ). The magnetic field sensor ( ) registers the change of field, which is then used to produce a switching signal.
