Abstract: A pair of external vehicle mirrors with a driver-side external vehicle mirror and a passenger-side external vehicle mirror are provided. Each have a mirror foot and a mirror housing pivotably attached, in which an adjustable mirror glass is arranged. The mirror housings of the two external vehicle mirrors are constructed symmetrically, so that an identical oncoming wind flow situation is achieved, and that on a rear side of the two mirror housings there is arranged a mask encompassing the mirror glass, the mask of the driver-side external vehicle mirror being formed asymmetrically to the mask of the passenger-side external vehicle mirror.

Abstract: The present invention relates to a method for producing trimethylolpropane having a low color number by processing a raw reaction solution obtained according to the inorganic Cannizarro process while adhering to precisely defined pH values.

Abstract: The present invention relates to a method for isolating ditrimethylol propane from secondary trimethylol propane production streams.

Abstract: The invention relates to an optimised wind turbine blade including: a first component (7) having an aerodynamic profile with a leading edge (11), a blunt trailing edge (13) with a thickness T greater than 2 mm and suction and pressure sides (17, 19) between the leading edge (11) and the blunt trailing edge (13); and a second component (9, 12) for reducing the noise from the blunt trailing edge, having a constant cross-section along the radius of the blade, which is securely joined to the blunt trailing edge (13) of the first component (7) in at least part of the wind turbine blade using coupling means that enable same to be replaced.

Abstract: The invention relates to a braking apparatus for a vehicle, having a first braking control device (6, 8, 9, 10, 15, 27) and a second braking control device (7, 16, 17, 18), in which case the vehicle can be braked both by operation of the first braking control device and by operation of the second braking control device. In order to carry out an automatic emergency braking process for the vehicle, the first braking control device interacts with a first evaluation unit (19), and the second braking control device interacts with a second evaluation unit (21), with the first evaluation unit (19) and the second evaluation unit (21) determining independently of one another whether the automatic emergency braking process should be carried out by operation of the respective braking control device, and the second evaluation unit (21) initiating the automatic emergency braking process when the first evaluation unit (19) and/or the first braking control device have/has a malfunction during operation.

Abstract: In a method for preventing a collision of a vehicle with an obstacle located on its front (such as preferably another vehicle traveling in front of the vehicle), the headway between the vehicle and the obstacle and the difference in speeds of the vehicle and of the obstacle (relative speed) and also the speed and acceleration/deceleration of the vehicle are detected and a collision message and/or a braking operation is triggered as a function thereof. The driver's activity, the state of the road, the loading state and the degree of overlap of the vehicle relative to the obstacle are detected, and from this information, a first headway (D_brake) between the vehicle and the obstacle is calculated, which is the least necessary to avoid a collision of a vehicle with the obstacle by steering the vehicle past the obstacle. In addition, a second headway (D_steer) is calculated, which is the least necessary to avoid a collision by steering the vehicle past the obstacle.
