Embodiment Construction

[0038] Spatial or directional terms used herein, such as "inner", "outer", "left", "right", "upper", "lower", "horizontal", "vertical", etc., refer to out of the invention. However, it is to be understood that the invention may assume many alternative orientations and these terms are not to be considered limiting. Moreover, all numbers expressing dimensions, physical properties, etc. used in the specification and claims are to be understood as being modified in all instances by the term "about". Accordingly, unless indicated to the contrary, the numerical values ​​set forth in the following specification and claims may vary depending upon the desired characteristics sought to be obtained by the present invention. At the very least, and not limiting the application of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. Moreover, all ran...

Abstract

An electrochromic switchable transparency, e.g. a window and / or a mirror includes an electrochromic switchable medium between a pair of electrode assemblies. At least one of the electrode assemblies is transparent to visible light and includes an electrode over a surface. In one nonlimiting embodiment of the invention, the electrode has two electrically conducting layers and a bridging layer between and interconnecting the two electrically conducting layers. In one nonlimiting embodiment, the bridging layer includes a high electrically resistance connecting layer to provide the electrode with a heating layer to heat the surface and / or a current conducting layer to pass current to the medium. In another nonlimiting embodiment, the bridging layer includes an electrically connecting layer to pass current to electrically enhance the first electrically conductive layer. In another nonlimiting embodiment, the electrically conducting layers are silver films to reduce infrared transmission through the first electrode assembly.
