註釋"An electrochemical device was developed to automatically provide vision protection for aircraft personnel during nuclear flashes. The requirements were that it have an optical density of 4 within 50 microsec, clear in 1 sec, and have an open-state transmission of 33% for visible light. In the original cell design, difficulties were encountered with the fabrication of conducting glass plates, contact resistances, and heavily loaded parallel circuits. To eliminate these difficulties, design changes were made; however, completed cells are not entirely satisfactory. All of the specifications, therefore, could not be met. Improvements are still possible in the size and weight of the electronic package, and in the lens plating time. It is concluded that, by placing 5 cells (with seriesconnected subelements) back-to-back, fabrication difficulties will be reduced and specifications met". -- page iii.
