Abstract:
The present invention discloses an amorphous material comprising nickel oxide doped with tantalum that is an anodically coloring electrochromic martial. The material of the present invention is prepared in the form of an electrode (200) having a thin film (202) of an electrochromic material of the present invention residing on a transparent conductive film (203). The material of the present invention is also incorporated into an electrochromic device (100) as a thin film (102)in conjunction with a cathodically coloring prior art electrochromic material layer (104) such that the devices contain both anodically coloring (102) and cathodically coloring (104) layers. The materials of the electrochromic layers in these devices exhibit broadband optical complimentary behavior, ionic species complimentary behavior, and coloration efficiency complimentary behavior in their operation.
Abstract:
Apparatus for providing ultra-accelerated natural sunlight exposure testing of samples under controlled weathering without introducing unrealistic degradation mechanisms in exposed materials and without breaking reciprocity relationships between flux exposure levels and cumulative dose that includes single or multiple concurrent levels of temperature and/or relative humidity at high levels of natural sunlight comprising: a) means for concentrating solar flux uniformly as concentrated uniform reflected or refracted light; b) means for achieving spectral splitting prior to directing the UV/VIS portion of the spectrum into the sample exposure chamber; and c) means for directing said controlled uniform reflected or refracted light onto sample materials in a chamber enclosure having single or multiple concurrent levels of temperature and/or relative humidity to allow the sample materials to be subjected to accelerated irradiance exposure factors for a sufficient period of time in days to provide a corresponding time of about at least a years worth of representative weathering of said sample materials.
Abstract:
A silver mirror construction that maintains a high percentage of hemispherical reflectance throughout the UV and visible spectrum when used in solar reflectors, comprising: a) a pressure sensitive adhesive layer positioned beneath a silver overlay; b) a polymer film disposed on the silver overlay; c) an adhesive layer positioned on the polymer film; and d) a UV screening acrylic film disposed on the adhesive layer.

Abstract:
System and method of modeling optical systems (339). Experimental data representative of exisitng systems may be used for ray-tracing exisitng optical system. Generalized models may be developed to model multiple stages having multiple elements in an optical system. Graphical user interfaces enable generalized model parameter entry, model execution (420), model editing, and graphical output (400) of ray-tracing results.
