Patent attributes
A system for selectively attenuating light from a source of light, such as the sun, to a person's eyes in a vehicle. The system includes an electro-optical element (10) interposed between the source of light (16) and the person's eyes (14). The element (10) has pixels (18) that are operable to individually attenuate (38) light passing therethrough. A navigation system (28) determines a location and direction of travel of the vehicle. A memory (24) contains a general location for the person's eyes within the vehicle. Information (32) is made available for determining a position of the source of light. A controller (24) operates to determine those pixels of the elements that are calculated (38) to be between the person's eyes and the source of light, and to reduce the light transmittivity of those pixels (38) to attenuate the light from the source (16) to the person's eyes (14).
