Abstract: A tool is proposed to assist detachment of an apparatus which has a housing adhering flatly on a pane, particularly of a sensor on the front windscreen of a vehicle, in which the apparatus housing has a surface with an exposed edge spaced from the pane. The tool has the form of a lug which has at least one engagement member on one longitudinal end, which engagement member can be engaged on the exposed edge of the apparatus and is provided with an opening or recess for a lever tool at a longitudinal distance from the engagement member. The tool is applied to the apparatus by engaging the engagement member behind the exposed edge on the apparatus housing. Then the lever tool, e.g. a simple bar or a screwdriver, is pushed through the opening or recess and is applied to bear on the top of the apparatus housing. The free end of the lever is then slowly raised, thereby lifting the housing off the pane.

Abstract: The method operates with successive, continuously repeated measuring cycles. In a first cycle section, a measuring capacitor is charged up to a first threshold value by the current flowing in a light receiver of a first optical measuring section. In a subsequent, second cycle section the measuring capacitor is discharged to a second threshold value by the current flowing in a light receiver of a second optical measuring section. The light transmitters of the optical measuring sections are regulated over several measuring cycles to predetermined rated values for the charging time and the discharging time. A wetting of the pane is concluded from the momentary deviations between the rated values and the actually measured values of the charging times and discharging times. The available modulation range is adapted dynamically to the prevailing conditions by the systematic control of the intensity of the light transmitters in the two optical measuring sections.
