  • Patent number: 5642022
    Abstract: An aircraft window shade speed control system which allows the coordination of window shade movement speed throughout an aircraft using a single set-point device for each window shade. Each window shade is moved by an electric motor, and its travel is limited by upper and lower limit switches. Voltage is applied to each motor by a motor control module that is relatively insensitive to variations in aircraft electric buss voltage and motor current requirements. A remote operation switch allows the pilot of the aircraft to open or close all window shades in the aircraft simultaneously, and to be assured of their ultimate position by observing only the window nearest his own position.
