  • Publication number: 20120019891
    Abstract: An electrochromic vehicular window system having a multiplicity of individually electrically switchable electrochromic elements, a vehicle operator face (eye) sensor to determine the position of the face of the operator in the vehicle, a sensor of the source external light entering the vehicle and impinging on the operators eyes and a system processor utilizing data from the sensors to determine and control which portions of the electrochromergic window to activate (or deactivate) so as to automatically reduce or eliminate glare on the eyes of the operator while still allowing essentially normal light transmission through other sections of the window. The system can also include a control switch for manual operation and or limiting the degree of light attenuation.
