Abstract: Methods, systems, and techniques for controlling a variable transmittance optical filter involve determining at least one of a temperature of, color of, and current flowing through the optical filter, and adjusting the voltage applied across the filter in response to at least one of the temperature, color, and current. The transmittance of the optical filter decreases until reaching a minimum on exposure to a first stimulus and increases until reaching a maximum in response to application of a second stimulus, and at least one of the first and second stimuli involves applying a voltage across the filter.

Abstract: A variable transmittance vehicle window may adjust its transmittance in response to readings from an interior light sensor that is positioned to measure intensity of at least one wavelength of light that is a proper subset of the visible spectrum and that has entered the interior of a vehicle comprising the window after passing through the window. If the intensity of light inside the vehicle is too high, the window is darkened; analogously, if the intensity of light inside the vehicle is too low, the window is lightened. Additionally or alternatively, the window may be transitioned to and maintained at an intermediate transmittance that is between the window's maximum and minimum transmittances.
