Patent ID: 8334623

Claim:
A method for preventing objects or parts of a body from being trapped between at least two mutually relatively moveable parts of which at least one part has associated therewith at least one strip which comprises at least two mutually spaced conductive elements that extend in the longitudinal direction of the strip and both of which are arranged in the strip, wherein an electronic sensor system coupled to the strip is provided for producing an output signal for a capacitance the value of which is adapted to vary as a result of the presence of an object, wherein at least one first conductive element sends out a signal which is received by at least one second conductive element due to capacitive coupling with the first conductive element, wherein the second conductive element at substantially the same electrical potential as the first conductive element likewise sends out the received signal and is electrically connected to the electronic sensor system for the purposes of relaying a change of capacitance resulting from the presence of an object on the electronic sensor system caused by an external influence, the change of capacitance causing a deviation of a control value; evaluating the control value; and ceasing and/or reversing movement of the moveable parts if the control value exceeds a threshold value.
