WOODBURY, N.Y., Jan. 27, 2011 (GLOBE NEWSWIRE) -- Garden Grove, California based GKN Aerospace Transparency Systems, Inc. has expanded its current license from Research Frontiers Inc. to now also include SPD-Smart windows, window shades, interior partitions, cabin dividers and other products for aircraft. The fees and minimum annual royalties payable to Research Frontiers and other license terms were not disclosed. Prior to this license expansion, GKN's business focused on SPD-Smart bullet-resistant glass and transparent armor for passenger cars, trucks, trains, RVs, armored personnel carriers, tanks, amphibious vehicles and warships. SPD-Smart light-control film technology transforms widely used products – windows, skylights, partitions and sunroofs – into products that allow users to instantly and precisely control light, glare and heat in their environment. In aerospace, dimmable windows using this technology allows passengers and crew much greater control of the aircraft cabin environment, thereby improving safety and comfort, and improving the flying experience. SPD-Smart technology offers many other desired benefits such as increased security, noise reduction, protection from harmful ultraviolet light and the potential for aesthetically distinctive designs. Joseph M. Harary, CEO of Research Frontiers, noted: "A talented and dedicated team at GKN has worked hard over the past three years to develop SPD-Smart transparent armor products for the commercial, military and government markets. In the process they have developed expertise using our SPD-Smart technology. GKN is a leading supplier to the global aerospace market and we look forward to their applying this experience to the growing market for electronically dimmable aerospace products."
