A construction of commercial aircraft interior monument employs carbon fiber Spread Tow Fabric (STF) as face sheets (skins) surrounding a paper honeycomb or foam core to produce flat pressed panels of high strength and desirable thickness. Each individual panel is joined with other panels to construct a modular rectangular cubic able to be modularly coupled with additional structures to form the aircraft monument. The use individual STF panels offer a desirable weight and footprint of a fabricated structure as a whole. Also usable in conjunction with other composite reinforcements, the individual STF panels produce hybrid lay-ups for both pressed flat panel and tooled composite moldings offering a high strength to weight ratio of the overall monument.

A test module for functionally testing an audio device of an aircraft passenger service unit (PSU) is configured to allocate a first operating mode to a first individual audio device of one PSU of a set of PSUs during which, a test tone is emitted. The test module allocates a second operating mode to other audio devices different than the first audio device. In the second operating mode, the test tone emitted by the first audio device is intended to be received. The other audio devices each belong to different PSUs within the set of PSUs. The test module emits the test tone via the first audio device. The test module initiates a functional test of the first audio device. The functional test is based on the test tone received by the other audio devices. The test module may be part of a system and an aircraft.

A component positioning system and method are configured to facilitate positioning of a component (such as a seat assembly) on a seat track within an internal cabin of a vehicle. The component positioning system and method include a component, and a position indicator coupled to a portion of the component. The position indicator emits a proper position indication when the component is in a proper position in relation to the seat track. The position indicator emits a remedial position indication when the component is not in the proper position with respect to the seat track.

An accommodation system for an accommodation space for storing rollable containers in a vehicle. After a front container, which is arranged at the insertion opening, has been removed in the conventional manner, it is possible, through the use of the accommodation system, to remove the rear container which is arranged considerably spaced apart from the insertion opening in the interior of the accommodation space. For this purpose, a rail system is provided in the floor region of the accommodation space. A transfer plate is movable on the rail system in the floor region of the accommodation space and can assume a storage position and a removal position for the rear container.

A galley system within an internal cabin of an aircraft includes one or more inboard cart compartments that are configured to removably retain one or more first galley carts, and one or more outboard cart compartments. The outboard cart compartment(s) are configured to removably retain one or more second galley carts. The inboard cart compartment(s) extend forwardly and/or rearwardly in relation to the outboard cart compartment(s).

A retaining assembly and method for use within an internal cabin of an aircraft, in which the retaining assembly includes a hinge including a biasing member. The hinge is moveable between a retaining position, in which the biasing member is configured to exert a biasing force into a top surface of a ceiling panel within an internal cabin of a vehicle to prevent the ceiling panel from upward motion, and a release position, in which the hinge is configured to be pivoted away from the ceiling panel and the biasing member is configured to be separated from the ceiling panel.

The present invention pertains an overhead unit (1) for presenting information, gathering information, transferring information, lighting and/or alarm signals in an individualized manner in a carriage or fuselage, comprising a function module (2), a fixation module (3) for removably attaching the overhead unit to a rail, two receival modules (5a, 5b) for receiving signals, two transmission modules (4a, 4b) for sending messages and a processing module (6) for processing messages, whereby the receival modules and the transmission modules are operationally connected to the processing module, wherein the fixation module comprises a mechanical fixation system (7) configured to interlock with a fixation system of the rail, wherein the overhead unit comprises a proximal longitudinal end (9) and a distal longitudinal end (10), wherein the receival modules comprise a proximal receival module located at the proximal end of the overhead unit and a distal receival module located at the distal end of the overhead unit, whereby the receival modules each comprise a sensor, wherein the transmission modules comprise a proximal transmission module located at the proximal end of the overhead unit and a distal transmission module located at the distal end of the overhead unit, whereby the transmission modules each comprise a transmission source, wherein the processing module of the overhead unit is configured to receive signals via the receival modules from a neighbouring overhead unit or from a neighbouring control unit, and/or wherein the processing module of the overhead unit is configured to cause the transmission modules to send out signals to a neighbouring overhead unit and/or the control unit.

The aircraft intercom employs beam steerable microphone arrays and speaker arrays deployed in each of a plurality of zones within the aircraft. A speech recognizer generates recognition text from utterances picked up by the microphone arrays. A direction control processor analyzes the arrival time of signals from the microphone arrays to identify utterance location, which is then used to control the beam direction of at least one steerable speaker array. A dialogue manager processor coupled to the speech recognizer and to each of the plurality of microphone arrays and plurality of speaker arrays responds to a set of predefined keywords to selectively route a voiced communication from a first selected zone to a second selected zone using the microphone array and speaker array disposed in each of the first and second selected zones.

A sanitization apparatus includes an excimer lamp, a power converter configured to power the excimer lamp and a controller. The controller is configured to monitor an impedance of the excimer lamp and vary an output voltage waveform of the power converter based upon the impedance.
