The system has an optic fiber (14) mounted within the cover (15) or frame cover (13), with a light source transmitting light along the fiber from one end and a light detector located at the other end. A reduction in detected light intensity is caused as the fiber is pressed by an obstacle trapped by a rising pane, with the window motor being stopped or reversed based on the detected light intensity compared to predetermined reference levels. |
