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.

Abstract: According to a visibility adjusting apparatus of a vehicle, an apex T is disposed at a position deviated from a driver and between a position opposed to the driver and a vehicle center position, left and right ridgelines uniformly downwardly inclined from the apex T to the vehicle-width direction are set, and a visibility adjusting section is formed as a parting line which adjusts a lower end visibility of the windshield. The visibility adjusting section is formed of the apex and the left and right ridgelines. With this, a sense of balance of the driver can be stabilized by the inclined parting line, and the sway of a head inclination angle can be suppressed.
