20090283728 | LIGAND EXCHANGE THERMOCHROMIC, (LETC), SYSTEMS - Ligand exchange of thermochromic, LETC, systems exhibiting a reversible change in absorbance of electromagnetic radiation as the temperature of the system is reversibly changed are described. The described LETC systems include one or more than one transition metal ion, which experiences thermally induced changes in the nature of the complexation or coordination around the transition metal ion(s) and, thereby, the system changes its ability to absorb electromagnetic radiation as the temperature changes. | 11-19-2009 |
20100316846 | METHOD AND CONSTRUCTIONS FOR MOISTURE SENSITIVE LAYERS AND STRUCTURES HAVING REDUCED MOISTURE CONTENT IN MOISTURE SENSITIVE LAYERS - Alternating layers of a first moisture sensitive layer are formed with a second desiccant containing layer. The desiccant containing layer removes moisture from the first moisture sensitive layer and maintains the first layer in a relatively dry condition. | 12-16-2010 |
20110075244 | THERMOCHROMIC WINDOW STRUCTURES - An energy efficient, thermochromic device that may be used to allow sunlight or solar radiation into a building or structure when sunlight is absent or at high sun angles and substantially blocks solar radiation when sunlight is directly on the window. | 03-31-2011 |
20120001134 | LIGAND EXCHANGE THERMOCHROMIC, (LETC), SYSTEMS - Ligand exchange of thermochromic, LETC, systems exhibiting a reversible change in absorbance of electromagnetic radiation as the temperature of the system is reversibly changed are described. The described LETC systems include one or more than one transition metal ion, which experiences thermally induced changes in the nature of the complexation or coordination around the transition metal ion(s) and, thereby, the system changes its ability to absorb electromagnetic radiation as the temperature changes. | 01-05-2012 |
20120138875 | ANTI-YELLOWING FOR THERMOCHROMIC SYSTEMS - Ligand exchange thermochromic systems comprising a. a transition metal ion, iodide; and at least one material capable of minimizing or eliminating yellow color formation in the system, wherein at 25° C. the color coordinate b* value of the system is less than 30. | 06-07-2012 |
20120292581 | LIGAND EXCHANGE THERMOCHROMIC SYSTEMS AND HIGH E LIGANDS FOR SAME - Ligand exchange of thermochromic, LETC, systems exhibiting a reversible change in absorbance of electromagnetic radiation as the temperature of the system is reversibly changed are described. The described LETC systems include one or more than one transition metal ion, which experiences thermally induced changes in the nature of the complexation or coordination around the transition metal ion(s) and, thereby, the system changes its ability to absorb electromagnetic radiation as the temperature changes. | 11-22-2012 |
20130229702 | ENHANCED THERMOCHROMIC WINDOW WHICH INCORPORATES A FILM WITH MULTIPLE LAYERS OF ALTERNATING REFRACTIVE INDEX - A window comprising at least one thermochromic layer and a film comprising multiple layers of polymer with alternating refractive index (MLARI). The thermochromic layer has a reversible change in absorbance of electromagnetic radiation such that the absorbance increases as the temperature of the thermochromic layer increases and the absorbance decreases as the temperature of the thermochromic layer decreases. Particularly useful thermochromic materials are ligand exchange thermochromic materials. In various embodiments, the window may have multiple panes and may incorporate a low-e layer. | 09-05-2013 |
20130286461 | SYNERGISTIC REVERSIBLE CHROMISM - A multilayer laminate and, more particularly a variable transmission window, which comprises:

20140134367 | CONSTRUCTIONS FOR MOISTURE SENSITIVE THERMOCHROMIC LAYERS AND STRUCTURES HAVING REDUCED MOISTURE CONTENT IN THERMOCHROMIC LAYERS - A stack or roll of alternating layers of films or sheets. The stack or roll includes an interlayer film or sheet with a thermochromic PVB of a polymer, at least one transition metal ion, at least one high epsilon ligand capable of forming a high epsilon metal-ligand complex with the transition metal ion and at least one low epsilon ligand capable of forming an low epsilon metal-ligand complex with the transition metal ion. A desiccant-containing film or sheet is juxtaposed or interleaved with the interlayer film or sheet. The desiccant-containing film or sheet prevents blocking of the interlayer film or sheet and is capable of removing moisture from the interlayer film or sheet. The desiccant-containing film or sheet is releasably attached to the interlayer film or sheet. | 05-15-2014 |
