1. A dimming system for a vehicle, comprising:
- a first sensor positioned to sense a position of an occupant of the vehicle and generate corresponding data;
at least one processor in communication with said first sensor and configured to receive the data generated by said first sensor and determine a position of at least one eye of the occupant based at least partially on the data generated by said first sensor;
a second sensor configured to sense a field of view outside of the vehicle and generate corresponding data;
said at least one processor in communication with said second sensor and configured to receive the generated data and to determine a position of an external light source in the field of view; and
a liquid crystal display (“
LCD”
) disposed at least partially in a field of view of the occupant and including a plurality of liquid crystals configured to be selectively operated in response to a command;
said at least one processor configured to calculate an intersection location of the LCD and a line between the at least one eye of the occupant and the external light source, and wherein said at least one processor is configured to selectively command said LCD to activate at least one of the plurality of liquid crystals at or near the calculated intersection location.

Abstract
A dimming system for a vehicle includes a sensor to sense a field of view and a liquid crystal display (“LCD”) having a plurality of liquid crystals. A processor in communication with the sensor and the LCD receives a position of an eye of the occupant and determines a position of an external light source in the field of view. The processor is also configured to calculate an intersection location of the LCD and a line between eye of the occupant and the external light source. The processor is further configured to selectively command the LCD to activate at least one of the plurality of liquid crystals at or near the calculated intersection location.

12. A method of providing dimming of a light source external from a vehicle, said method comprising:
-
sensing a position of an occupant of the vehicle and generating corresponding data with a first sensor; determining a position of at least one eye of the occupant based at least partially on the generated data utilizing a processor; sensing a field of view outside of the vehicle and generating corresponding data with a second sensor; determining a position of an external light source in the field of view utilizing the at least one processor; positioning a liquid crystal display (“
LCD”
) at least partially in a field of view of the occupant, the LCD including a plurality of liquid crystals configured to be selectively operated in response to a command;calculating an intersection location of the LCD and a line between the at least one eye of the occupant and the external light source; and selectively commanding the LCD to activate at least one of the plurality of liquid crystals at or near the calculated intersection location. - View Dependent Claims (13, 14, 15)

16. A dimming system, comprising:
-
at least one processor configured to receive data related to a position of at least one eye of a person; a sensor configured to sense a field of view of the person and generate corresponding data; said at least one processor in communication with said second sensor and configured to receive the data generated by the sensor and to determine a position of an external light source in the field of view based at least partially on the data; and a selectively translucent material disposed at least partially in the field of view of the person and including a plurality of dimming elements configured to be selectively operated in response to a command; said at least one processor configured to calculate an intersection location of the selectively translucent material and a line between the at least one eye of the person and the external light source, and wherein said at least one processor is configured to selectively command said selectively translucent material to activate at least one of the plurality of dimming elements at or near the calculated intersection location. - View Dependent Claims (17, 18)
