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.

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: A lavatory for an aircraft cabin includes a wall having a forward wall portion disposed immediately aft of and substantially conforming to an exterior aft surface of an aircraft cabin structure, such as a passenger seat, that is substantially not flat in a vertical plane. The forward wall portion includes a forward projection over an aft portion of the adjacent passenger seat. The forward wall portion can define a secondary space in the interior lavatory space, which can provide an amenity stowage space, and can include design elements providing visual space.

Abstract: A proximity switch flow sensor detects movement of a faucet handle of a faucet of a hot water container in order to detect flow from the hot water container. The proximity switch flow sensor includes an emitter paired with a detector, which can be mounted in association with the faucet handle to detect open and closed positions of the faucet handle, to provide electronic logic information regarding the status of the faucet handle position, as an indication of a flow condition, to a control unit that controls heating of water in the hot water container. An electro-mechanical switch and a mechanism to transfer movement of the faucet handle to the switch may also be used to detect open and closed positions of the faucet handle as an indication of a flow condition.

Abstract: The electro-optic liquid level sensing system detects a level of liquid in a container having an upper opening, such as for a server container of a beverage maker for a transport system, such as for aircraft, trains, trucks, buses and the like. A support housing mates with the upper opening of the container, and a primary liquid level sensor is mounted in the support housing for non-intrusively measuring the liquid level. A secondary liquid level sensor may be mounted in the support housing to sense a predetermined liquid level to prevent accidental overflows. Protective lenses may be placed in front of the primary liquid level sensor.

Abstract: The liquid galley refrigeration system for cooling food carts for aircraft employs an intermediate working fluid to transfer heat from one or more food carts to one or more remote chillers, allowing the carts and chillers to be advantageously distributed in the aircraft. While the chiller working fluid undergoes a phase change in order to transfer heat from the intermediate working fluid to the cooling air, the intermediate working fluid remains in its liquid phase throughout its circulation. A recirculation pump circulates the intermediate working fluid through a distribution system that may link a plurality of chillers to a plurality of food carts, and the temperature of the food carts is regulated by a combination of controls.
