Abstract: In a preferred embodiment, an apparatus for eye tracking, including: an illuminator; reflection apparatus to reflect illumination from the illuminator onto a surface of a windshield of a vehicle in which the windshield is installed, such that the illumination is reflected onto at least an eye of a person in the vehicle, and to reflect an image of the at least an eye, and a sensor to receive a reflection of the image of the at least an eye reflected by the reflection apparatus and to produce an output signal representative thereof.

Abstract: A head up display (HUD) has multiple light sources of varying intensities for projecting a high quality image under various lighting conditions. The light sources provide illumination through an electronic display (e.g. an AMLCD) in the HUD. A high brightness light source illuminates the electronic display during bright or day light conditions. A low brightness light source illuminates the electronic display during night or low light conditions. Both light sources illuminate the electronic display during intermediate lighting conditions. A light panel conducts and diffuses light from the light sources to illuminate the rear of the electronic display. An optional light mixer reduces uneven lighting of the high brightness light source. In operation, the intensities of the light sources are controlled as a function of ambient lighting conditions to optimize the projected image quality.
