Smart Car Windows


Driving into the sunset without Smart Car Windows.


      When driving very early or late in the day, the sun can be blinding.  HinesLab Smart Car Windows eliminate this problem by creating a moving dark area on the glass that blocks the sun and eliminates the need to switch the visor from front to side.  

      A dark patch appears to slide around on the window glass to shade the driver’s eyes while turning.  The position of the dark area on the glass is determined using a fisheye camera on the dash to track the sun, and a microprocessor with driver input for eye position.

       A patch on the windows is darkened using electro-chromic glass technology used on auto-dimming rear view mirrors, or LCD-television-screen technology.  The driver does not see a dark patch, but rather the absence of the blinding sun in a more evenly lit sky.  

      The system can create moving dark spots for more than the driver at sunset… also for road glare, oncoming headlights at night, and additional dark spots for passengers.  

      The system also compensates for side windows being partially rolled down.  When a window is rolled down, the dark area on the glass appears to remain stationary as the glass slides down out of it, and reappears as the the window rolls up again through it.  When the car is parked, all windows darken to protect the valuables inside.  

      The Smart Window technology would provide the same benefit in commercial and military aircraft, especially useful for military fighter pilots.
