Abstract
An electrically controlled dimmable window for aircraft includes a controller and power that eliminates the need for wiring connections to on-board systems. The controller is integrated into the sidewall in which the window is mounted. Power for controlling the window is derived from an energy harvesting device that generates power by converting thermal gradients, motion/vibration or light energy present near the window. The integrated controller includes passenger controls for adjusting the opacity of the window, power conditioning circuitry, an electrical power storage device such as a battery, a processor and a radio receiver. The window can be remotely controlled by a cabin attendant from a central controller that transmits window control signals to the radio receiver.
