Systems with synchronized windows
First Claim
1. A vehicle, comprising:
- a body having an interior;
control circuitry;
an adjustable window in the body that is between the interior and an exterior region surrounding the body, wherein the adjustable window has an optical property that is modulated by the control circuitry; and
a light source that produces output light that is modulated by the control circuitry in synchronization with the modulation of the optical property of the adjustable window, wherein the light source comprises an internal light that emits the output light and wherein the output light at least partially illuminates the interior.

Abstract
A system such as a vehicle may have window that exhibit adjustable transparency. The windows may include liquid crystal devices and polymer dispersed liquid crystal devices that exhibit adjustable amounts of light transmission and haze. An optical property of a window such as window transparency may be modulated using an alternating-current modulation waveform. Modulation of the transparency of the window may be synchronized with modulated light output from a light source. The light source may be located inside the vehicle or may be located outside of the vehicle. By synchronizing the modulation of the transparency of the window with the light source output, privacy may be enhanced or glare may be reduced.
