Window system with indicia
First Claim
1. A window system comprising:
- an electro-optic element comprising;
a first substantially transparent substrate defining first and second surfaces, wherein the second surface comprises a first electrically conductive layer;
a second substantially transparent substrate defining third and fourth surfaces, wherein the third surface comprises a second electrically conductive layer;
a primary seal disposed between the first and second substrates, wherein the seal and the first and second substrates define a cavity therebetween; and
an electro-optic medium disposed in the cavity, the electro-optic medium being variably transmissive such that the electro-optic element is operable between substantially clear and darkened states;
a polymeric dust cover positioned away from the electro-optic element defining at least two major surfaces; and
at least one indicia disposed in the dust cover, the indicia comprising a plurality of damage channels having an aspect ratio greater than about 10;

Abstract
A window system is provided that includes an electro-optic element having a first substantially transparent substrate defining first and second surfaces. The second surface has a first electrically conductive layer and a second substantially transparent substrate defines third and fourth surfaces. The third surface has a second electrically conductive layer and a primary seal disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic medium is disposed in the cavity that is variably transmissive such that the electro-optic element is operable between substantially clear and darkened states. A polymeric dust cover is positioned away from the electro-optic element defining at least two major surfaces and at least one indicia disposed in the dust cover. The indicia includes a plurality of damage channels having an aspect ratio greater than about 10:1.
