UFO sightings are an everyday occurrance at Dubai International Airport. Five polished stainless-steel spaceships, each about 20 feet wide and weighing nearly two tons -- suspended from steel cables -- appear to hover in the air in the Sheik Rashid terminal. Osram Opto Semiconductors, based in Regensberg, Germany, outfitted each ship with more than 8500 LED modules and special optics that tightly focus the light beams in a controlled sequence that, combined with the effects of "smoke" canons, simulate takeoff and landing. Other participants in the joint project were Ontario Light; Ontario architect Herbert Demanega; KCA International (concept and design); Otto Valenta GmbH, of Austria (construction, steel structures, engineering); and Elmar Schrutek, of Vienna (control technology). . . . Robert Moody has been named regional sales manager at Lincoln Laser, a Phoenix, Ariz.-based maker of precision polygonal mirrors, optics, high-speed motors and motor controllers for laser scanning applications. He was previously commercial products manager and regional sales manager for Axsys Technologies in Rochester Hills, Mich., and was formerly a business unit manager at Ferrofluidics Corp., in Nashua, N.H.
