Electronic sun shield
First Claim
Patent Images
1. A substantially transparent window, the improvement comprising:
- (a) an electrochromic material;
(b) means dividing the electrochromic material into at least four sectors which may function independently and are arranged in a grid-like pattern with adjacent said sectors abutting;
(c) said electrochromic material being placed in adjacency to said window for selectively obscuring at least a portion of said window located adjacent said sectors; and
(d) control means for selectively obscuring some or all of said sectors by controlled application of electrical current on said electrochromic material;
(e) each said sector being of sufficient size that, when obscured, eyes of a user are shieldable from the sun.

Abstract
The electronic sun shield is an electronically operated grid that enables the operators of motor vehicles and other vehicles (such as airplanes) to control the shading of their windshields. It employs electrochromic technology to electronically darken section or sections of the windshield in order to minimize the effects of glare from the sun, reflective objects, or the lights of other vehicles, as driving conditions dictate. In addition, all sections of the windshield can be darkened at once when the vehicle is parked, or at other times, to shield the interior from the sun.

8. In a substantially transparent window, the improvement comprising:
-
(a) an electrochromic material; (b) means dividing the electrochromic material into at least four sectors which may function independently and are arranged in a grid-like pattern; (c) said electrochromic material being placed in adjacency to said window for selectively obscuring at least a portion of said window located adjacent said sectors; and (d) control means for selectively obscuring some or all of said sectors by controlled application of electrical current on said electrochromic material said control means including circuit means for controlling obscuring of any one or more of said sectors, said circuit means including compass means for sensing the orientation of said window and, responsive thereto, controlling obscuring of one or more of said sectors. - View Dependent Claims (9, 10)
