摘要： The present invention provides a a headlight operable as a running light of a vehicle and, in particular, as a headlight of the vehicle for selectively projecting a low and a high beam. The headlight includes a reflector having a light source disposed therein. A beam position adjusting device operates to move the light source between its low beam position and its high beam position. The beam position adjusting device includes an electric powered drive motor and a displaceable interconnecting element interconnecting the beam position adjusting device and the light source. The device also includes a motion translation element for translating the drive output of the drive motor to displacement of the displaceable interconnecting element, the beam position adjusting device being operable to dispose the light source in its high beam position. A return movement device automatically biases the light source to move to its low beam disposition when the drive motor is not powered.

摘要： A pneumatically striking hand-held power tool is controlled by the following steps. An acceleration (a) along a striking axis (8) of the hand-held power tool (1) is detected. A driving power is reduced if the detected acceleration (a) is greater than a threshold value (A), the threshold value (A) being selected to be greater than maximum acceleration values (a1, a2) that occur on a workpiece during the striking operation of the hand-held power tool (1).
