Abstract
A system and method for controlling the intensity of light into a cabin space is provided. The system includes a controller in communication with a window. The window is configured to have variable transmittance. The system further includes a sensor operable to detect the state of a pupil. The sensor is also in communication with the controller. The controller processes the state of an iris of a user so as to adjust the transmissivity of the window. Accordingly, the intensity of light entering into a cabin space may be controlled so as to facilitate the vision of the occupants.
Claims14
A system for controlling the intensity of light entering a cabin space, the system comprising:
- a controller;
- a window having variable transmittance, the window in communication with the controller;
- and
- a sensor operable to detect the state of an iris, the sensor in communication with the controller, the controller processing the state of the iris so as to adjust the transmissivity of the window.
A method of controlling the intensity of light entering a cabin space, the method comprising the steps of:
- providing a window having variable transmittance;
- detecting the state of an iris;
- adjusting the transmissivity of the window based upon the state of the iris.
