Abstract: A laser projection device is described for projecting laser beams onto a projection plane, including a controllable multibeam laser diode unit; including a controllable optical deflection unit, which is designed in such a way that laser beams generated by the multibeam laser diode unit are deflected with the aid of the deflection unit; and including a control unit, which is designed in such a way that it controls the deflection unit to move laser beams deflected by the deflection unit onto a projection plane along a scanning line in such a way that different deflected laser beams run in the projection plane on the same scanning line.

Abstract: A method for controlling a micro-mirror, having the following: generating a first control signal which encodes a tilting motion of the micro-mirror about a first tilt axis, at a first frequency; generating a second control signal which encodes a tilting motion of the micro-mirror about a second tilt axis which is perpendicular to the first tilt axis, at a second frequency which is lower than the first frequency; modulating the second control signal by binary modulation of the second control signal, at the first frequency; and controlling force coupling elements of the micro-mirror, using the modulated second control signal and the first control signal.

Abstract: The quantitative determination of aging effects on motor oil is of great interest. According to a method, two variables of the motor oil are detected, one of the two variables being the viscosity and the other variable being the acid content of the motor oil. A first deviation of the detected first variable from a default value is then determined, and the second variable is estimated based on the deviation. By determining a second deviation of the estimated second variable from the detected second variable, the second deviation is determined as a measure of the aging effect on the motor oil. Since various aging effects influence the two variables in different manners, individual aging effects may be quantitatively determined in a targeted manner.
