ABSTRACT:
Apparatus for an electrically moved sliding window, used illustratively in automotive applications, having first, a built-in safety device, for providing a signal whenever the window has been raised or lowered to a preselected height and second, a proximity detector is described. The device and detector comprise a plurality of conductors, bonded to the surface of the window. These conductors are, in turn, connected to an integrated circuit element which is also mounted to the surface of the window. This circuit element controls a power stage which, in turn, supplies power to the drive motor which raises and lowers the window. The circuit element and the conductors are placed directly on the window in a stationary position with respect to one another.
