| 20100236729 | TOR II - The invention concerns a gate with a section that is movable, along a preferably prescribed track that features a, for the most part, rectilinear running section, between a closed position and an open position, a controller that is designed for the purposes of controlling the gate section movement and for the generation of first control signals for preferably the purpose of stopping the gate section movement in the event of leaving the prescribed track, whereby associated with the controller is a transmitter arrangement for the purposes of generating two, three or more signals that run along approximately perpendicular to the prescribed track and approximately parallel to a, during the closing movement, preceding edge of the gate section as well as spread on sequentially arranged signal paths, in the direction of the gate section movement, whereby the signal paths during the course of the closing movement are chronologically sequentially interrupted and/or during the course of the opening movement are chronologically sequentially released, particularly by the gate section's edge that precedes during the closing movement. | 09-23-2010 |
