ABSTRACT:
A windshield wiper for cleaning the windshield of motor vehicles, where a vertically moving wiper blade extends across the width of the windshield. The wiper blade has a generally triangular cross section with concave walls for collecting water and dumping it in front of the blade. There are two cleaning edges; one for cleaning on the downstroke, and one for cleaning on the upstroke. Sensors are placed at desired locations around the periphery of the windshield to sense the moisture when precipitation occurs and are connected in the windshield wiper circuit to activate the wipers accordingly.
