ABSTRACT:
A sliding window assembly for moving a window between a cavity defined by a structure having an outer surface, and a space located above the cavity comprises a first motor for selectively moving the window between the cavity and the space and a second motor for selectively moving the window between a first position substantially aligned with the cavity and a second position substantially aligned with the outer surface. First sensors indicate when the window is substantially entirely within the cavity and when the window is substantially entirely within the space. Second sensors indicate when the window is in the first position and when the window is in the second position. In one embodiment of the invention, third sensors indicate when the window is positioned for the second motor to move the window between the first and second positions. A programmable logic controller is connected to the sensors for appropriately controlling the motors.
