In May 2006, Evans & Sutherland divested itself to Rockwell Collins, Inc. of the simulation business of the firm's operations - involving two-thirds of its then 300 employees. Instead the firm opted to focus its energies on its digital theater and laser projector businesses. Evans & Sutherland Computer Corporation - originally NASDAQ: ESCC, now OTC: ESCC - had worked on visual systems that provided simulation training for various military and commercial applications. In the 1970s management had purchased General Electric's flight simulator division and formed a partnership with Rediffusion Simulation, a UK-based flight simulator company, to design and build digital flight simulators. For the next three decades this was E&S's primary market, delivering display systems with enough brightness to light up a simulator cockpit to daytime light levels. These simulators were used for training in in-flight refueling, carrier landing, AWACS, B52 EVS, submarine periscope and space station docking. Follwing the divestiture, Evans & Sutherland Computer Corporation now works on visual display systems used primarily in full-dome video projection applications, dome projection screens, and dome architectural treatments worldwidey. Products include planetarium and dome theater systems consisting of proprietary hardware and software, and other visual display systems primarily used to project digital video on large curved surfaces. It also produces content for planetariums, schools, science centers, other educational institutions, and entertainment venues; and show content for its own library that it licenses to customers and for specific customer requirements for planetarium and dome theaters. In addition, the company manufactures and installs metal domes with customized optical coatings and acoustical properties that are used for planetarium and dome theaters, and other custom applications; and designs and supplies geometrically complex structures for customized architectural treatments
