Abstract: In a folder, a folding cylinder having folding components accommodated on the periphery thereof and being phase-dependently operatable, and cylinder segments for carrying the folding components, the cylinder segments being adjustable in relation to one another and being mounted coaxially in side walls, includes separate drives, respectively, for driving each of the folding components, a rotary leadthrough via which energy is supplied to the separate drives, and a speed controller for speed-dependently controlling the separate drives; a method of operating the folding cylinder; a folder including the folding cylinder; and a rotary printing machine in combination with the folder including the folding cylinder.

Abstract: A digital telecommunication facility has a base station and one or more cordless mobile units that communicate with the base station through a TDMA process. The mobile units and the base station change the transmitting/receiving frequency within which they communicate only once per TDMA frame and the retain the new transmitting/receiving frequency for a time corresponding to an entire TDMA frame.

Abstract: A control unit for an automatic transmission of a motor vehicle has a position detection sensor that supplies an analog output signal that is dependent on a position of a selector slide. The position detection sensor is adjusted using a self-learning algorithm in an electronic control system of the control unit during operation of the motor vehicle.
