Abstract: A pneumatic brake booster for motor vehicles, comprises a booster housing, the interior of which is separated into a working chamber and a low-pressure chamber by an axially movable wall that can be supplied with a pneumatic differential pressure; a control housing; and a control valve which controls a differential pressure between the working chamber and the low-pressure chamber. The control valve controls an airflow between the working chamber and the low-pressure chamber or a surrounding atmosphere. The control valve has a plate valve and a valve piston, a seal region of which can be sealingly placed on the plate valve and which can be moved in a stroke direction R. A fine and low-noise metering of the brake force is achieved by providing a throttle point between the valve piston and the plate valve for throttling the airflow dependent on the stroke.

Abstract: A method for determining an energy yield loss of a first wind turbine of a wind farm that includes a plurality of wind turbines. The first wind turbine is operated in a reduced energy yield mode that is outside an energy-optimized normal operating mode and a reduced energy yield of the first wind turbine is determined. At least one second wind turbine is selected according to a pre-determinable criterion. The energy yield of the at least one second wind turbine is determined and depending upon the energy yield of the at least one second wind turbine, an energy yield potential of the first wind turbine is determined. The difference between the energy yield potential of the first wind turbine and the determined reduced energy yield is formed.

Abstract: A brake actuating unit for actuating a motor vehicle braking system of the “brake-by-wire” type having a brake booster. In order to provide a brake actuating unit for actuating a motor vehicle braking system of the “brake-by-wire” type, which on the one hand fulfills the statutory requirements care and which on the other hand is inexpensive to produce, it is proposed according to aspects of the invention, that the brake booster be provided as a travel-controlled brake booster, so that when not in the “brake-by-wire” operating mode the brake pedal is decoupled from feedback forces of the brake actuating unit, and the return force is simulated by the pedal travel simulator even when not in the “brake-by-wire” operating mode.

Abstract: A method for determining an energy yield loss of a first wind turbine (1-49) of a wind farm (51) that includes a plurality of wind turbines (1-49). The first wind turbine (1-49) is operated in a reduced energy yield mode that is outside an energy-optimized normal operating mode and a reduced energy yield of the first wind turbine (1-49) is determined. At least one second wind turbine (1-49) is selected according to a pre-determinable criterion. The energy yield of the at least one second wind turbine (1-49) is determined and depending upon the energy yield of the at least one second wind turbine (1-49), an energy yield potential of the first wind turbine (1-49) is determined. The difference between the energy yield potential of the first wind turbine (1-49) and the determined reduced energy yield is formed.
