Abstract: A window arrangement for a vehicle subject to pressure changes may include a first transparent member and a second transparent member spaced apart from one another. A flexible seal may be interposed between the first transparent member and the second transparent member. A hermetically sealed variable volume enclosure is sealed off from a cabin interior. The hermetically sealed variable volume enclosure may be bounded by the first transparent member, the second transparent member, and the flexible seal joining the first transparent member and the second transparent member around a perimeter thereof. The flexible seal may have an elastically mobile body structured and arranged to permit relative movement between the first transparent member and the second transparent member to change a volume of the enclosure in response to a pressure change in the cabin interior to equalize a pressure differential between the enclosure and the cabin interior.

Abstract: A window system for an enclosure subjected to a change in air pressure, the enclosure having a window having an air-filled cavity, the system including a first path configured to allow air within the cavity of the window to vent out of the cavity, a second path configured to allow air to flow into the cavity, and a drying agent disposed within the second path, where moisture in the air entering the window cavity through the second path is reduced by the drying agent.

Abstract: A method, system and controller for controlling power supplied to a heating device of a window on a vehicle, comprising receiving information indicative of at least one parameter associated with operation of the vehicle, generating a power signal at least in part on a basis of the information indicative of the at least one parameter and stored control logic, the power signal being indicative of a power modulation level for power to be supplied to the heating device and transmitting the power signal to a power regulator for causing power to be supplied to the heating device in accordance with the power modulation level.
