Abstract: An optical arrangement of data smart glasses includes a first laser device configured to emit a projection light beam, a second laser device configured to emit a measuring light beam, a first scanner, a second scanner, and a beam combiner configured to bundle the projection light beam and the measuring light beam into a common light beam, wherein the first scanner is configured to deflect the projection light beam emitted by the first laser device in a first axis, and wherein the second scanner is configured to deflect the common light beam focused by the beam combiner in a second axis.

Abstract: A method for separating asphaltenes from an asphaltene-containing fuel, wherein fuel is supplied to a separation unit in which a sub-stream with low-boiling fuel components of the fuel is separated. After separation of the sub-stream the fuel is supplied to a deasphalting unit in which asphaltenes contained in the fuel are separated by a solvent. After the separation of the asphaltenes from the fuel, the solvent is separated therefrom in a solvent recovery unit. The separated solvent is circulated back into the deasphalting unit, and a solvent fraction is obtained from the sub-stream that has been separated from the fuel, which is supplied to the deasphalting unit in addition to the solvent recirculated from the solvent recovery unit. A device is adapted for separating asphaltenes from an asphaltene-containing fuel.

Abstract: A motor vehicle has a warning device for drivers of vehicles traveling behind in situations with strong braking deceleration. This warning device exhibits a warning signal transmitter, preferably formed by flashing indicators, a sensor for sensing the situation with strong braking deceleration and which is formed by the sensor for sensing an emergency braking situation of a braking assistance device, and a control unit for controlling the warning device, which is preferably embodied with the control device for controlling the braking assistance device as a common control unit, in particular in a common housing. This warning device proves very robust, very secure, and reliable in its operation.
