Development automatic control of pumps used for underground grout injection (firms: Soletanche, Keller, Bilfinger und Berger) development of a GPS based satellite navigation device for mobile use (airplanes, land vehicles, ships) vehicle guidance system based on 'moving map' (GPS) system for quality assurance during production of injection moulding parts (Wilden) specific CNC machines with charging (Ski Völkl, mt-propeller) computer control for internal highpressure forming regulations for hydraulic pressure and movements of hydraulic cylinders measuring device for airplane navigation software for data base applications micro processor electronics and peripherals Deep Drawing of Tin Sheets: Hydraulic Down Holder Control (BHDR) The challenge of quick control of strong forces has initiated the development of a specific hydro-electric automatic control system. With this device in hydraulic presses the steering of the force in a predefined dependence on the propagation becomes possible. At the car manufacturer Audi the system has been retrofitted to work with 5 headpresses (400 to 1800 tons) in everyday production. - A mechanical press was equipped at Hoesch. Due to the high speed control it worked up to 30 cycles per minute. The equipment is installed at Audi, BMW, and Hoesch.
