Abstract: The aircraft emergency oxygen supply system includes one or more sources of supplemental breathable oxygen, one or more inlet valves for one or more breathing devices, connected to the inlet valves, and one or more cabin air pressure transducers. A pressure controller controls the inlet valves in response to the one or more cabin air pressure transducers. One or more second pressure transducers may connected to conduits downstream of inlet valves to be monitored, and the pressure controller may also control operation of the inlet valves in response to the one or more second pressure transducers.

Abstract: A refrigerator-oven combination for an aircraft galley food service system includes a housing with a thermally insulated compartment, a heating device for heating the compartment in a heating mode, and a refrigeration device for cooling the compartment in a refrigeration mode. The heating device includes an electric heater and a steam injection valve disposed within the compartment for heating at least a portion of an interior of the compartment. A temperature sensor disposed within the compartment measures a temperature in the compartment during the heating mode. The refrigeration device may be a chiller that supplies chilled fluid to the compartment, or a separate refrigeration unit which is mounted to the compartment. A control unit connected to the steam injection valve, electric heater, temperature sensor, and refrigeration device is configured to monitor and control the temperature within the compartment during the heating and refrigeration modes.

Abstract: A brewing system for brewing a beverage is disclosed having an inlet for receiving fresh water for brewing, and a first solenoid for directing water to a water storage tank when a level in the water storage tank falls below a predetermined level. A pair of pumps direct water from the storage tank to a second solenoid. Two or more brew paths lead away from the second solenoid, each brew path including a heating element to heat the water flowing therethrough. The second prevents overpressurization in the brew paths by routing excess pressurized water from the respective brew path back through the second solenoid and out a drain line leading to a drain, where the path to the drain is not part of the brew path.

Abstract: An emergency oxygen supply system for use on aircraft in the event of a loss in cabin pressure is configured for delivering allotments of oxygen and timing the delivery such allotments to each passenger so as maximize the efficiency of the transfer of such oxygen into the passenger's bloodstream. The delivery of each allotment is selected so that the entire allotment is available for inhalation into the region of the lung most efficient at oxygen transfer while the volume of the allotment is selected to substantially coincide with the volume of such region of the lung.

Abstract: An interior ceiling panel system includes a ceiling panel mounted in a ceiling area, a first airflow directing panel in a first side of the ceiling area defining an airflow passage, and a second airflow directing panel in a second side of the ceiling area, defining an eddy space. An airflow supply source introduces airflow into the ceiling area, and the second airflow directing panel provides an obstruction that creates an eddy in the eddy space that incoming airflow with air in the cabin. One or more speakers project sound energy upward toward the ceiling panel, which deflects sound energy to provide more uniform sound levels in the cabin.

Abstract: An aircraft galley system is configured with a GAIN to GAIN network that allows for data exchange and communication between each GAIN on the system. By omitting reliance on a galley network controller for acquisition of GAIN data, the present system is simpler, lighter, and more cost-effective. Each GAIN may be polled for data by any other GAIN, such as via a data port, dedicated bus, or wireless connection. The data acquisition between the GAIN and a data collection and display device may be wired in network, wired out of network, or through a wireless link such as a Wi-Fi network.

Abstract: An electrically activated latch for aircraft stowage bins includes an overhead stowage bin module having a stationary support structure and a movable stowage bin portion. An electrically operated stowage bin latch mechanism latches the movable stowage bin portion in a closed position and unlatches the movable stowage bin portion to an open position. An electrically operated stowage bin activation switch operates the stowage bin latch mechanism, allowing the aircraft stowage bins to be locked by independently controlling the overhead stowage bins through the aircraft cabin management system, or by control of the latch by the stowage bin activation switch.

Abstract: An aircraft crew rest station includes an overhead crew rest portion including a central deck portion, forward and aft bunk portions, and a central entry vestibule connected between a passenger seating area and the central deck portion. The forward and aft bunk portions include a plurality of adjacent partitioned individual sleeping berths configured in interfitting alternating trapezoid shapes to optimize spatial accommodation of body proportions of crew members in the available aircraft space. The central deck portion includes an emergency escape hatch, a fold-down jump seat, and a fold-down entry door that removably covers a stairway of the central entry vestibule.

Abstract: A lift assist mechanism is provided for assisting lifting of a movable component that can move between lowered and raised positions relative to a fixed structure. The lift assist mechanism includes a lift assist spring connected to a spring shaft, and an elongated track in which an end of the lift assist spring or an end of the spring shaft are movably engaged. A spring lock restrains movement of the spring shaft when a lift assist is not required, and releases the spring shaft when a lift assist is required.

Abstract: A brew basket for a brewing apparatus is disclosed having a housing adapted to couple the brew basket to a brewing apparatus and a platform extending from the housing, the platform including a brewing chamber defined by a continuous peripheral wall and a perforated floor. The perforated floor is coupled to a vertically reciprocating member at a first end for raising and lowering the perforated floor of the brew basket with respect to the continuous peripheral wall, the vertically reciprocating member extending below a lowermost surface of the platform so that it can be raised by lowering the platform onto a flat surface.
