SPD-Smart electronically dimmable window shades supplied by Research Frontiers (Nasdaq: REFR) licensee Vision Systems are being presented by an OEM in their full cabin mockup at the 49^th International Paris Air Show being held from June 20-26, 2011 at Le Bourget Airport in France.

Vision Systems’ SPD-Smart Nuance and Noctis aerospace windows offer instant and precise light-control at every level which provides original equipment manufacturers and private aircraft owners a solar protection solution that enhances flying comfort and supports fuel efficiency. These electronically dimmable aircraft and helicopter window shades and cabin dividers are impact-resistant, completely silent, available in flat and curved surfaces, and can be controlled by the cabin management system or by passengers. Vision Systems’ Noctis SPD-Smart product line offers enhanced blackout solar protection and complete privacy.

Carl Putman, CEO of Vision Systems, commented: “OEM interest in our Nuance and Noctis brand of SPD-Smart window shades has accelerated. Last month at the European Business Aviation Convention & Exhibition (EBACE) event in Geneva, visitors to our booth and also at our OEM customer’s mock-up at EBACE experienced for the first time in an aircraft mockup the many benefits that this technology offers to aircraft owners and operators from an operational standpoint, and the in-flight benefits for flight crews and passengers. Here at the Paris Air Show, yet another major OEM has exhibited this technology in a significant way as part of their full aircraft cabin mockup. These aircraft are scheduled to go into service in 2012 and 2013, and we have geared up our production accordingly based upon the very good order book that both of these aircraft have amassed already.”

Made with patented light-control SPD film developed by Research Frontiers and currently being produced by Hitachi Chemical Company in their dedicated factory line in Japan, SPD-SmartGlass is the world’s fastest-switching variably tintable dynamic glazing technology. It is the only dimmable window technology that gives users the ability to instantly and precisely control the level of shading to any point between very dark and clear. This provides exceptional control over solar energy while also adding to user comfort and protecting interiors. Available in both glass and lightweight polycarbonate substrates, SPD-Smart products – windows, sunroofs, skylights, doors, partitions and more – are laminated glazings that offer a distinctive combination of energy efficiency and security, can be controlled manually or automatically, and are available in custom sizes and fabrications for original equipment, new construction, replacement and retrofit projects.
