1. A method for calibrating a glare-shield comprising:
- measuring at least two relationships between a glare source and a glare calibration position; and
using the measured relationships, determining the location of a darkened spot on the glare shield in response to a specific location of glare on a glare sensor.

23. A system for the calibration of a glare-shield, comprising:
-
at least one glare source;
a darkened region on the glare-shield;
a calibration position for concurrently perceiving the glare source and the darkened region and adjusting the location of the darkened region relative to the glare source;
a microcontroller for determining at least a first and a second relationship between the location of the glare source, the darkened region on the glare-shield, and the calibration position;
memory, associated with said microcontroller, for recording first and second calibration data points for positions of the glare source on a photodetector associated with the glare-shield when the darkened region occludes the glare source; and
said microcontroller further determining, based upon the first and second calibration data points, a position of the darkened region in response to the glare source location on the photodetector. - View Dependent Claims (24, 25, 26, 27, 28)
