A working cylinder having at least one working chamber defined by the cylinder barrel, at least one of the end sections and a piston, at least one supply port and a exhaust port for the working medium. The device includes a processor configured to determine a first antitachycardia pulse routine of N pulses. The voltage transformer is so arranged that its ohmic resistance towards the measuring shunt on the one hand sufficiently limits standard direct-current impingement of the voltage transformer and on the other hand this ohmic resistance is also small enough so that, together with the inductance of the current transformer, it displays no more than standard angle error. Alternately, when the user initiates a telephone connection to place a call, a charge option message is presented providing the user with an option to listen to an advertisement before placing the call. 75, and the output of the electric motor is controlled to be held or reduced, when the turning state has come to be out of such a range that the rolling motion of the vehicle body can be actively controlled.
