Abstract
A detecting device includes an actuating unit for driving a transparent material, a light source for emitting light to the transparent material driven by the actuating unit, a light sensor for sensing the light emitted from the light source as an edge of the transparent material is moved to different positions relative to the light source so as to generate a corresponding optical intensity signal, a transforming circuit coupled to the light sensor for transforming the optical intensity signal into a transforming signal, and a processing unit coupled to the transforming circuit for determining whether the edge of the transparent material is moved to a position between the light source and the light sensor according to the transforming signal transmitted from the transforming circuit. And methods and systems for same.
