The handle (6) can be set in two different positions - one engaged with ...

The chromaticity coordinates of colourmetric reference elements are plotted on a CIE diagram to identify reference wavelengths. The ratio of reflected energy from an object at these two wavelengths may then be used to identify a particular colourmetric reference element. The procedure may be automated by electronic equipment A color which is already known approximately may be defined precisely by ...

Apparatus for automatic transverse vehicle guidance is provided for the automatic transverse guidance of a vehicle along a traffic lane. The apparatus can be activated in such a way using an activating actuation of an operating element that the actual transverse-position value present at the activation instant serves as a desired transverse-position value for subsequent automatic transverse guidan...
