Abstract:
A power window system comprising:a window frame;a window body movably disposed within said window frame, said window body and said window frame generally defining a window plane;a window motor connected to move said window body within said window frame;an optical emitter, oriented with respect to said window frame and said window body to emit optical energy within said window plane;an optical detector having segmented detector elements that are oriented with respect to said optical emitter to detect reflected portions of said optical energy from said optical emitter, said optical detector having a plurality of outputs associated with said segmented detector elements for outputting electrical signals in response to detection of said reflected portions of said optical energy; andmeans for processing said electrical signals from said plurality of outputs to determine the presence of an obstructing object within said window plane.
