A switching system, preferably for use in the power supply of motor vehicles, and having one chargeable energy memory of a specific voltage level and consumers situated in the circuit of the energy memory is further developed so that a significant power load is thoroughly prevented even in the case of a high momentary power requirement of the electric consumers. The method comprises generating a first vector of channel responses from channel estimations obtained by using a training signal. A modulation interface is adapted to output a power control signal to the EOM, and the EOM regulates the power of the light beam supplied to the first modulator to a power level corresponding to the power control signal. Level converters with fanin cones below a selected minimum cone size are deleted and low voltage sources to the deleted level converter reverted. The balloon is thereafter inflated with a hardenable media, and heated to accelerate hardening of the media. The variable flow regulating means serves to control the fluid surface levels in both vortex chamber and separation chamber.
