Abstract: The present invention relates to a method for avoiding a collision between a vehicle and another traffic participant. According to the inventive method, a cell phone carried by the traffic participant sends a signal including a position of the traffic participant. A processing unit processes the signal including the position of the traffic participant for a position or evaluation history. The processing unit determines an estimation of a future position of the traffic participant on the basis of the position or evaluation history. The processing unit evaluates a likelihood of a collision between the vehicle and the traffic participant on the basis of the estimated future position of the traffic participant and an estimation of a future position of the vehicle. An acceleration of the traffic participant is sensed by an acceleration sensor of the cell phone.

Abstract: The invention relates to a double-fed asynchronous generator, which is provided with a slipring rotor (1b), and to a method for its operation. In the normal manner, the asynchronous generator has a machine-side converter (5) and a network-side converter (6).

In order that inherent short-circuit currents in sensitive components of the converters (5, 6) are nevertheless avoided, at least the machine-side rotor current (iRM) is maintained in such a way that the actual rotor current (iRMact) in the event of a short circuit is used as the new nominal value in a control apparatus for the asynchronous generator.

Abstract: A biological wastewater is mixed in an activated sludge tank with activated sludge that is concentrated in the activated sludge tank to a predetermined value. The mixture of wastewater and activated sludge running off in a drain of the activated sludge tank is then sieved to effect an incomplete solid/liquid separation that leaves a separated solid phase in the activated sludge tank. The liquid phase including a remnant of solids is then removed from the tank.
