Abstract
Electrically dimmable windows for aircraft are powered by energy harvesting devices on-board the aircraft. The harvested energy is stored and used to control the opacity of the windows based on individual window opacity settings selected either by passengers or a cabin attendant. Each window has an associated control circuit that controls the electrical power applied to the window based on the selected opacity setting. The control circuit includes a low energy usage processor that remains in a sleep mode until a change in the opacity setting is detected. Each control circuit may include a radio transceiver that receives control signals from a transmitter operated by the cabin attendant in order to simultaneously remotely control the opacity settings of multiple windows.
