1. A system for controlling a power-driven window glass slidably movable between closed and opened positions in a window opening defined in a motor vehicle by an electrically conductive window frame, comprising:

  • a sealing or guiding strip attachable to the window frame for sealing or guiding the window glass as it moves between the opened and closed positions, the sealing or guiding strip being made of plastics or rubber material and incorporating only a single electrode electrically insulatingly embedded within the plastics or rubber material,electrical circuit means for producing an electrical output,connecting means connecting the single electrode to the electrical circuit means such that the presence of a part of the human body at or not more than a predetermined distance from the single electrode produces a change in the electrical output,detecting means responsive to the change in the electrical output to produce an output signal, andoutput means responsive to the output signal for interrupting sliding movement of the window glass in the window opening,the electrical circuit means producing the electrical output as an electrically oscillating output.
