A supplemental oxygen assembly for a vehicle can include a container and a flow assembly attached to and/or configured to be contained within the container in a stowed position and to extend from the container in a deployed position. The flow assembly can be configured to be connected to an oxygen supply to supply oxygen to a person in the deployed position. The supplemental oxygen assembly can include an extension device connected to the flow assembly. The extension device can be configured to extend or allow extension of the flow assembly toward an aisle of the vehicle to aid the flow assembly in being reached from or moveable toward an aisle of the vehicle by a person in the aisle.

The invention provides a kit of parts for assembling an aircraft seat unit, comprising a frame with a slot, a panel for forming a shell of the aircraft seat unit and defining a footprint of the aircraft seat unit, having a first end and a second opposite end, the first end configured to be slid in and out of the frame slot to provide a variable dimension from the frame to second opposite end of the panel, and a fixing mechanism for fixing the panel within the frame slot, in a configuration providing a desired value of aircraft seat unit variable dimension. The invention also provides a plurality of such kits of parts, an aircraft seat unit and an aircraft cabin comprising a plurality of such aircraft seat units or made from such kit of parts, and methods of installing an aircraft seat unit.

A system for stock management for on-board catering for a vehicle, in particular for an aircraft, includes a galley which is provided with a control unit for controlling the galley, wherein the control unit is designed to make available stock management data of the galley; a service unit for transporting supplies within the vehicle, wherein the stock management data comprise a stock record of the supplies transported with the service unit; and at least one operator control element which is communicatively connected to the control unit of the galley via a wireless data connection and is designed to record removal of a supply item from the service unit and/or reception of a supply item into the service unit, and to bring about updating of the stock record of the transported supplies on the basis thereof.

A seatbelt detection system detects seatbelt use in each seat of a passenger aircraft to produce safety-compliance data. A computer system, which is communicatively coupled to the seatbelt detection system, receives sensor data from a plurality of sensors in an aircraft cabin; and employ an artificial intelligence (AI) program to train on input data comprising at least one of safety compliance data, aircraft system data, cabin environment data, cabin operations data, or aircraft operations data; and the AI program is configured to minimize a summed error of predictions of seatbelt compliance.

A tolerance compensation subassembly in the form of a tolerance compensation element or a tolerance compensation region to improve the production, maintenance and repair of aircraft. The tolerance compensation subassembly contains an actuator which is formed from an electro-active polymer so that the tolerance compensation subassembly is electrically switchable between a fixed state and a non-fixed state. As a result, automation of the assembly of aircraft components on each other can be enabled or facilitated.

An ultra light weight aircraft composite galley architecture system and method comprises composite construction of a partially molded aircraft monument structure based on embedded load bearing hoops and beams used in conjunction with pre formed composite flat panel construction. An upper L shaped structural section mates with a lower inverted L shaped structural section forming a structure upon which additional panels are joined to form the complete composite galley. This system and method of construction produces a high strength aircraft monument capable of maintaining aircraft structural flight and crash load requirements without external monument extrusions for support. This galley architecture system and method of construction creates an aircraft monument with desirable reduction in weight with no loss of required structural strength.

An aircraft projection device includes a projector that displays an image by projecting the image onto a floor surface of a passage in an interior of an aircraft; and a controller that controls the projector to display the image onto the floor surface of the passage in the interior of the aircraft.

According to some examples of the presently disclosed subject matter there is provided a system and method for deploying a plurality of unmanned aerial vehicles (UAVs) by an airborne carrier aircraft for dispersing payload material, each UAV comprising at least one container containing payload material and being configured to disperse the payload material at a designated dispersion area in an event site.

A passenger service unit, a passenger seating area, and a vehicle having a passenger service unit are provided, wherein the passenger service unit comprises a carrier element that can be extended in a longitudinal direction and a covering. The covering covers at least a section of the carrier element. At least one electrical and/or electronic element is integrated in the covering.
