From page 41 of: Defining the Relationship Between Human Error Classes and Technology Intervention Strategies Douglas A. Wiegmann and Esa Rantanen Year 1 Technical Report ARL-02-1/NASA-02-1 January 2002 Prepared for NASA Langley Research Center Hampton, VA Contract NASA NAG 1-01-026 1-82.... "83. Aircraft Window Shading Device. Research Frontiers has developed a new window-shading device for aircraft installations. It uses a suspended particle device (SPD) to control light. SPD refers to light absorbing microscopic particles suspended between two electronically coated surfaces. The film is placed between two panes electrically coated conductive plastic/glass. The application of an electric voltage will increase or decrease the amount of light allowed through the window. When the switch is turned off by the passenger particles are randomly dispersed and absorb light creating a dark appearance. When the switch is turned on the particles align and the glass will change from dark to clear. New SPD film window applications will reduce aircraft operating weight and increase passenger comfort by allowing them to better control window light. [Bokulich, F. (2001, July).
