Abstract: A system and method for exiting an overhead area in an aircraft. An egress apparatus is automatically moved from a closed state to an open state in response to opening a hatch that closes an opening in an overhead area in an aircraft. The apparatus comprises a platform attached to a substantially vertical structure by a first hinge structure. A guide panel is attached to the platform by a second hinge structure. The apparatus is configured to be moved from a closed state to an open state. The platform extends outward from the substantially vertical structure and under the opening in an overhead area in an aircraft when the apparatus is the open state. The guide panel extends upward from the platform when the apparatus is in the open state.

Abstract: A system and method for exiting a crew rest area located in an overhead area in an aircraft. An opening in the crew rest area is located in an overhead area in the aircraft. An egress apparatus is configured to move between a closed state and an open state. The egress apparatus is configured to direct a person moving on the egress apparatus from the opening to a passenger cabin in the aircraft when the egress apparatus is in the open state.

Abstract: A dimmable window testing system comprises a light source configured to emit a beam of known intensity through a dimmable element of an electrically dimmable window system. A light intensity sensor measures a light intensity of light emitted from the light source through the dimmable element.

Abstract: Systems and methods for controlling windows with variable light transmission are disclosed. In one embodiment, a system includes a sensor adapted to receive a light intensity, a user input device adapted to receive a user input value, a window having a variable transmissivity portion, and a control system. The control system is operatively coupled to the sensor, the user input device, and the window, and is adapted to receive the light intensity and user input value and to adjust a transmission level of the variable transmissivity portion of the window based on at least one of the light intensity and the user input value. The sensor includes a sensor adapted to receive a light intensity, a temperature, a humidity, or other environmental variables. In other embodiments, the system also includes a ventilation system, an air conditioning system, or a humidity control system.
