Abstract: A device for multi-channel signal transmission between mobile units, including at least one first transmitter/unit that is coupled to at least one second transmitter/receiver unit via transmitting means. Further more the first transmitter/receiver unit and the second transmitter/receiver unit provide mutually tuned filter banks that filter predetermined characteristic spectral fractions out of the signal to be transmitted and which combine these signals to form a cumulative signal in the cast of transmission, that pass on these signals via directional switches which separate the signals of the transmission and reception path from each other or combine transmitted and received signals in such a way that they will be transmitted via common transmitting means.

Abstract: In a device and a method for measuring path lengths, particularly of brushes in sliding contacts, an air stream having a regularly fluctuating pressure is provided by a pump and conducted via an air supply line and a nozzle to an object to be measured. The object is disposed so that its length or position affects the flow resistance of passing air. A consequent pressure drop in the supply line is determined with a pressure sensor, and an evaluation unit computes, in particular from the difference between maximum and minimum air pressure, a length of the object as a function of the pressure difference. In another embodiment of the invention, pressurized air is supplied from a pump to an object to be measured, and a sensor is disposed to detect a pressure change when the object has attained a predetermined length.
