Abstract:
The invention provides an anti-trap protection system for a moving system. The anti-trap protection system comprises a capacitor system, with a first electrode device, which comprises a first and a second electrode, and a second electrode device, which comprises a third and a fourth electrode; an LC oscillating circuit formed by the first electrode device and an inductance; a signal generator for charging the first electrode device and the second electrode device with an adjustable frequency and amplitude; and a capacitor for coupling the signal generator with the first electrode device and the second electrode device; whereby the signal provided by the signal generator and the signal present at the LC oscillating circuit form a first indication for an approach of an object to the electric field of the first electrode device, and the signal provided by the signal generator and the signal tapped at the fourth electrode form a second indication for an approach of an object to the electric field of the second electrode device.
