Abstract

An object detection system includes a sensor in communication with a controller which identifies contact with the sensor. In a preferred embodiment the sensor is a piezo film which generates a signal when an object applies a predetermined force to the edge of the moveable glass member. This signal is identifiable by the controller in communication with the piezo film. Another embodiment of the sensor provides a pair of substantially parallel segments of conductive material applied along the edge of the window. When an object is in contact with both segments of conductive material an electrical signal is conducted and identified by the controller. When the controller determines an object is in contact with the sensor and therefore the moveable glass member, the controller halts or reverses the movement of the moveable glass member to prevent trapping the object between the closing moveable glass member and the frame.
