<p>An obstruction detection system utilizes a segmented optical detector and detector-specific signal processing to optically detect the presence of a small object within a defined plane and to screen out interfering signals. In one application, the obstruction detection system is utilized with an automatically closing window to prevent small objects, such as fingers, from being pinched by the window as the window is being closed. In one embodiment of the obstruction detection system, the segmented optical detector includes a series of segmented detector elements that are generally perpendicular to the defined plane. In another embodiment of the obstruction detection system, the segmented optical detector includes segmented detector elements that are generally parallel to the defined plane.</p> |
