Abstract
Variable transmission covering systems that can be used, for example, to control the amount of light passing through a window in a building. Using transmissive electrophoretic media that can switch between a first and second optical state, the invention can be used to change the color and/or transmissivity of a structure (or structures) that is placed in front of an object. In some embodiments, the variable transmission system can change transmission and color on command.
