[0007] The object of the present invention is to propose improvements regarding the design of a Passenger Service Unit, also called a PSU.

[0008] The problem is solved by a PSU with the features of claim 1. Preferred or advantageous embodiments of the invention, as well as other categories of invention, will become apparent from the further claims, the following description, and the accompanying figures.

[0009] The Passenger Service Unit, hereinafter referred to as PSU, is designed to be arranged or installed inside a passenger cabin. In particular, the PSU is designed to form a visible surface of the passenger cabin or to be attached to the visible surface of the passenger cabin, preferably being mounted on a ceiling area.

[0010] The PSU has a modular design and comprises a base body and at least three modules, with the modules arranged on the base body. The base body serves as a frame or mounting structure for the modules.

[0011] In particular, the base body can also be part of one or more of the modules; that is, the base body is not a separate component but an integral part of at least one of the modules. Crucially, the modules must be mechanically attachable to one another via the base body to form the PSU or at least a part thereof.

[0012] In particular, the base body can be designed as a single piece or in multiple parts. In the multi-part version, the base body can be designed such that the individual parts each serve as a frame structure or mounting structure for one of the respective modules. Alternatively, the base body can be made up of several individual parts, which are joined together to form a single frame structure or mounting structure. Furthermore, the base body can be separate, i.e., independent of the modules, or integrated into the modules, or be part of one or more modules. Alternatively, the base body can also be formed by one or more modules. In particular, the modules can be in direct contact with the base body or arranged on the base body via other components.For example, the base body can also be designed as a socket for the respective modules or have sockets for the respective modules. Furthermore, the respective modules can be connected to the base body via different types of connections. For example, the respective modules can be connected to the base body by frictional, force-fit, form-fit, and / or material-fit connections. Preferably, at least one, and particularly preferably all, modules are connected or connectable to the base body by detachable connections.

[0013] The individual modules are, in particular, functional modules, each of which is designed for one or more functions, the function(s) of each module differing from the function(s) of the other modules. The modules can be single-part or multi-part. Alternatively, the modules can be interconnected to form a unit. Another alternative is that two or more modules are interconnected to form a unit. Each module comprises at least one functional component, and each module can also comprise several functional components. In particular, each module can be formed by one or more functional components.Preferably, the respective functional components are connected to the respective modules or configured so that they can be connected to the respective modules, the connection being either mechanical or electrically conductive. In particular, each functional component can be configured for one or more specific functions. Alternatively, several functional components of a respective module can be configured for one or more specific functions. The PSU comprises at least one oxygen supply module, one ventilation module, and one electronics module, each of which is configured as one of the modules. The oxygen supply module includes, as a functional component, at least one or more oxygen generators or oxygen containers.Furthermore, the oxygen supply module also includes one or more oxygen masks and one or more oxygen piping systems, wherein the oxygen piping system is designed for transporting oxygen from the oxygen generator(s) or the oxygen container(s), and wherein the oxygen piping system and / or the oxygen masks may each be designed as a functional module. The oxygen supply module serves to provide a passenger with oxygen in an emergency situation.

[0014] The ventilation module serves to ventilate an area in the passenger cabin. The ventilation module can be configured to generate one or more airflows or to direct one or more airflows. The ventilation module has one or more, preferably three, air outlets, which in particular have a nozzle shape. The air outlets are designed as the functional components of the ventilation module. In particular, the air outlets are arranged to be movable or movable within the ventilation module. Preferably, the ventilation module also has control elements or regulators for controlling or regulating the airflow at the air outlet, which are designed as further functional components. The control elements or regulators can be mechanical and / or electrical or electrically controllable. In particular, the ventilation module has one or more control elements or regulators per air outlet.

[0015] The electronics module incorporates electronic or digital display elements and / or control elements, which are designed as the functional components. The electronics module thus contains all electronic control, display, and operating functionalities of the PSU, as well as all control, display, and operating devices that implement these functionalities. The control, display, and operating devices are the aforementioned functional components or are formed / implemented by them. Control, display, and operating functionalities each relate to a person's interaction with the PSU via electrical / electronic means. In other words, all electrically / electronically operating HMI (Human Machine Interface) functionalities and HMI devices (control, display, and operating devices in the form of functional components) are solely contained within the electronics module.

[0016] However, the rest of the PSU (outside the electronics module), for example in the ventilation module, may contain other electrical / electronic components such as motors, sensors, actuators, etc., which do not serve the HMI functionality described above. "Non-electronic" control, display, and operating functionalities, i.e., corresponding non-electrically based display and control elements, etc., may also be present outside the electronics module in the PSU. These could include, for example, mechanical HMI elements such as levers / adjustable knobs for directing airflow or opening / closing an air flap.

[0017] The electronic module can include purely electrical and / or electromechanical control elements or regulators, which can be used to control or operate the electronic module itself and / or to control or operate functions of other modules. Furthermore, the electronic module has at least one display (in the form of a display device), which is designed to convey information to a passenger. The term "display" is to be understood broadly here and includes anything that can convey information to a person, in particular visual (e.g., a display), acoustic (e.g., a loudspeaker or audio interface), and haptic display devices (e.g., a Braille module for outputting Braille). In particular, the display can also be configured to enable interaction between a passenger and the electronic module, i.e., to allow input from the passenger to the electronic module via this display.For example, the display can be configured to show operating functionalities of the electronic module and / or other modules. Preferably, the display is also designed to show control functionalities, allowing a passenger to operate functions of the electronic module and / or other modules via the display. The display can, for example, be configured as a screen and / or speaker.

[0018] Preferably, the electronic module is designed such that the respective functional modules can be connected to a power and / or voltage source / interface of the electronic module via simple connections, such as plug or clip connections. Furthermore, the electronic module is preferably designed such that it can be controlled via one or more cables or via one or more power rails and / or supplied with current and / or voltage, for example via power line communication. The electronic module is preferably designed to allow for a simple connection, such as a plug or clip connection.

[0019] The modular design of the PSU has the advantage that the individual modules and / or the respective functional components can be replaced easily and cost-effectively.

[0020] In a preferred embodiment, the electronic module comprises a lighting device and / or a loudspeaker and / or a screen, in particular a touchscreen, as respective functional components. For the sake of simplicity, the term "touchscreen" will be used in the following, although a general screen (with or without operating functions) may also be meant. The lighting device is configured to illuminate an area of ​​the passenger cabin, in particular an area within the passenger cabin that can be adjusted by the passenger. The lighting device comprises one or more light sources, preferably three light sources, which are designed to be independently adjustable. For example, the respective light sources can be adjustable purely electrically, purely mechanically, or electromechanically.The lighting device can be designed, for example, as a surface-mounted light, in particular as a surface-mounted light with three adjustable sections. The respective light sources can be designed, for example, as one or more LED point light sources. The electronic module is designed such that the lighting device, in particular the light sources, can be operated by electrical, mechanical, or electromechanical controls. The lighting device can be designed as a continuous unit or arranged in sections on the electronic module. The lighting device is designed so that it can be adjusted by a passenger.

[0021] The loudspeaker, as part of the aforementioned display functionality / display device, serves to output audio to a passenger, which can be either a tone or a voice. For example, the loudspeaker can be configured to emit a tone or voice after a passenger operates functions of the electronic module. Furthermore, the electronic module can also include additional loudspeakers. The screen, as part of the aforementioned display functionality / display device, is in particular a touchscreen or touch display and is then designed as a touch-sensitive screen. The touchscreen can be configured, in particular, so that the entire display area is touch-sensitive, or so that only one or more sub-areas of the display area are touch-sensitive. Various functional principles are possible for implementing touch sensitivity.For example, resistive, surface capacitive, projected capacitive, inductive, sound wave-controlled, optical, or dispersive systems can be used. The touchscreen is integrated into the electronic module and, in particular, positioned so that the display area is aligned with the passenger's line of sight. The touchscreen is designed to generate an image on the display area, specifically to generate an image similar to a moving image, such as an animation. The touchscreen can, for example, include an LCD, LED, or OLED display to generate the image.

[0022] In a preferred embodiment of the aforementioned configuration with a screen, the screen / touchscreen is configured for displaying content, wherein the display content includes at least passenger information and several buttons, and wherein the touchscreen is configured for a passenger to retrieve the passenger information and operate the buttons. The passenger information can be displayed as text and / or images or symbols, in particular also in the form of a moving image. For example, the passenger information can include safety information, such as safety displays, travel information, service information, advertisements or advertising texts, or status displays of functions of the PSU or individual modules.The buttons are designed as digital keys on the touchscreen, which a passenger can operate by pressing the touchscreen. The touchscreen is configured so that individual, multiple, or all passenger information can be accessed through interaction between the passenger and the buttons. Alternatively, the touchscreen can be configured so that individual, multiple, or all passenger information can be accessed without requiring the buttons to be used. Preferably, the touchscreen is configured so that functions of the electronic module, in particular functions of individual or multiple functional components, can be operated via the buttons. Additionally, the touchscreen can also be configured so that further modules, in particular functional components of other modules, can be operated via the buttons.

[0023] In a further embodiment, the lighting device, in particular individual or multiple functional components of the lighting device, can be operated by at least one of several buttons. Specifically, the touchscreen is configured so that a passenger can activate and deactivate the lighting device, in particular individual light sources of the lighting device, using one of the buttons. Preferably, the touchscreen is also configured so that a passenger can control the light characteristics, such as the light intensity or the color of the light, using the same or another button. This can save costs, as mechanical components, such as knobs for adjusting the light, can also be omitted.

[0024] Furthermore, the touchscreen can also be configured so that one or more functional components of the ventilation module can be operated by at least one of the multiple buttons. In particular, the touchscreen is configured so that a passenger can activate and deactivate the airflow by pressing one of the buttons. Additionally, the touchscreen can be configured so that the strength and / or direction of the airflow can be adjusted using one or the same button. This can save costs, as mechanical components such as knobs or dials can be eliminated.

[0025] Preferably, the touchscreen is configured to control all functions of the electronic module and preferably also functions of one or more additional modules. In particular, all modules or functional components whose function can be controlled by the touchscreen are connected or connectable to the touchscreen via signaling.

[0026] In a first possible embodiment of the invention, the loudspeaker is designed as a piezoelectric loudspeaker. The piezoelectric loudspeaker is specifically designed for generating tones or signals. In particular, the piezoelectric loudspeaker is designed as a flat surface. Compared to magnetic or diaphragm loudspeakers, the advantage of the piezoelectric loudspeaker is that it has fewer components, thus saving costs. Alternatively, the loudspeaker can also be designed as a panel loudspeaker or planar loudspeaker. In particular, the panel loudspeaker is flat. For example, the panel loudspeaker can be designed such that a flat component is excited to vibrate and generates a sound. For example, a component of the power supply unit (PSU), such as a cover, a panel, or a grille, can be designed as the flat component.This allows the loudspeaker to be functionally integrated into the existing PSU design, thus saving costs for additional loudspeaker components. At least the electrically active parts of the loudspeaker, relevant for communication with the passenger, are part of the electronics module. These electrical components can be supplemented outside the electronics module by other loudspeaker parts, such as the aforementioned covers / panels, etc.

[0027] In a further embodiment of the invention, the electronic module is designed for communication between the passenger and the cabin crew. The electronic module can comprise one or more functional components configured to make a passenger's request visible or recognizable to the cabin crew. For example, the electronic module can include a control element which, when operated by the passenger, is configured to send a signal to the cabin crew or to signal a request to the cabin crew. The signal can appear on another or the same functional component of the PSU, in particular the electronic module, for example, as an audible signal and / or a visual signal. Preferably, the electronic module is configured such that a passenger can submit a request via the touchscreen.In particular, the touchscreen is also designed to display a passenger's request in order to alert the cabin crew. Alternatively or additionally, the electronic module can also be configured to send the request as a signal to a remote location within the aircraft. Preferably, the touchscreen is configured to display indicators and / or buttons that allow the passenger to specify the request. By integrating the communication capability between the passenger and cabin crew into the electronic module, especially the touchscreen, costs for additional components can be reduced. Preferably, the power supply unit (PSU) is designed such that the touchscreen is positioned at an angle of less than 90° to the aircraft's longitudinal axis on the PSU or the electronic module. In other words, this means that the touchscreen is positioned obliquely to the direction of flight.In particular, the touchscreen can be arranged on the PSU such that its display area is parallel to the aircraft's vertical axis. Preferably, the touchscreen is arranged on the PSU such that its display area is inclined towards the floor or towards the passenger cabin's seating row. This makes the display area more visible and simplifies operation of the PSU.

[0028] A further development of the invention provides that the PSU includes a projector for projecting an image, either as a separate module (in which case the projector does not perform any display functionality / does not serve as part of the HMI) or as a functional component of the electronics module (in which case the projector can be part of the display functionality / of the HMI). The projector can be configured as a separate module, in particular as a projector module, wherein the projector module is a separate electronics module and wherein the projector is arranged on the base body in the same way as the modules described above. Alternatively, the projector can be configured as a separate functional component of the electronics module and arranged on or in the electronics module as described above. The projector is specifically designed to generate or project a static image or an image resembling a moving image.For example, the projector can be configured to generate the same or different display content as that shown on the touchscreen. Specifically, the projector is positioned on the PSU so that an image can be projected by the projector onto a seat, a viewing surface of the cabin wall, or a designated area in the passenger cabin. For example, the projector can be designed and positioned to generate an image on the front or back of a seat, where the image could be, for instance, a seat number. This allows information to be displayed larger.

[0029] A further embodiment of the invention provides that the PSU includes a Braille generator as a functional component of the electronic module. The Braille generator has a haptic field with several individually adjustable raised areas for generating the Braille. This extends the display functionality / HMI to include haptic display / interaction capability. The Braille generator can be configured to display the same content as the touchscreen display area in Braille. Alternatively or additionally, other information or supplementary information can also be generated by the Braille generator.

[0030] For example, the braille generator can be configured to produce safety signs or symbols in braille. The braille generator can be designed, for instance, to be activated by placing a finger on it. Preferably, the braille generator is also configured to allow a passenger to input information via the haptic field or another component of the braille generator. This extends the control and operating functionality to include a braille / haptic component. For example, the braille generator can be configured to allow a passenger to communicate with the cabin crew through user input. This enables people with disabilities to use and operate the passenger information system (PSU).

[0031] One possible embodiment provides that the projector and the Braille generator are designed so that they can be mounted in the same area of ​​the PSU. In particular, the projector and the Braille generator are designed to have the same connections. Furthermore, the projector and the Braille generator have the same dimensions, at least in the area where they are mounted on the PSU or in the area that forms the viewing surface on the PSU. This makes it possible to replace the projector with a Braille generator without significant effort.

[0032] Another possible embodiment of the invention provides for Braille characters to be applied to or next to the touchscreen. The Braille characters are designed as raised dots. In particular, the individual dots can be applied directly to or next to the touchscreen, for example, as adhesive dots, or they can be located on a flat substrate, such as an adhesive strip, which is applied to or next to the touchscreen. The Braille characters serve, in particular, to indicate the functions of the PSU to a passenger. Alternatively or additionally, it is also possible for the Braille characters to be designed as control elements. For example, the Braille characters can be applied to a mechanical, electromechanical, or purely electrical control element. Furthermore, it is also possible for the Braille characters to designate a button on the touchscreen.Additionally, Braille characters can also be placed on other areas of the PSU. For example, they can be located on or next to the ventilation module to inform a passenger about the function of the ventilation system or its functional components.

[0033] In a preferred embodiment, the PSU is configured for speech output of displayed content. The PSU is designed so that the speech output is delivered via the built-in speaker or via speakers, audio-capable devices, or headphones that can be connected to or linked to the PSU. For this purpose, the PSU can be configured, in particular, such that the electronic module includes a functional component that serves as an interface for connectable devices. In other words, the interface is then part of the display functionality / HMI and enables communication between the PSU and users via the interface (and a speech output device powered by the interface). For example, the interface can be configured for wired or wireless connections.In particular, the PSU can be configured such that the speech output can be activated, deactivated, and preferably also controlled by one or more operating elements. For example, the operating elements can be designed as additional components of the electronic module, such as buttons or touch fields similar to a touchscreen. Alternatively, and preferably, the operating elements are designed as buttons on the touchscreen. In particular, the PSU is configured such that the speech output can be adjusted or controlled by the operating elements, for example, by changing the volume and / or language. The PSU can be configured in particular such that the same display content can be output as speech that is shown on the touchscreen. For example, safety-relevant information displayed as a symbol or safety indicator on the touchscreen can be output as speech.Alternatively or additionally, the PSU can be configured to output other information as speech output, independent of the displayed content. For example, PSU functions can be announced as speech output. This enables the PSU to be operated by people with disabilities or allows them to access passenger information.

[0034] An upgrade of the PSU (Power Supply Unit) provides an interface for wireless communication with a mobile device, such as a tablet, smartphone, or laptop. This interface is designed either as an extension of the existing electronic module (in which case the interface does not perform any control, display, or operating functionalities and is not part of the HMI) or as a functional component of the existing electronic module (in which case the interface can be part of the HMI's control, display, and operating functionalities). Specifically, the interface for wireless communication is designed as a functional component of the electronic module. In other words, the interface is then part of the control / display / operating functionality of the HMI and enables communication between the PSU and users via the interface (and a connected device).

[0035] Preferably, the PSU is configured to allow multiple mobile devices to be connected via its interface. Specifically, the PSU is configured to allow multiple mobile devices to be connected simultaneously. The PSU is configured so that a passenger can connect their personal mobile device or a mobile device provided to them via the mobile interface. For example, the PSU can be configured so that the mobile device can be connected via NFC, by scanning a QR code, or via an app that the passenger installs on their mobile device beforehand. The mobile device is configured at least to display passenger information, with the information being displayed on a screen, such as a display or touchscreen.For example, the mobile device can be configured to display flight data, service information, and weather information. Specifically, the mobile device can also be configured to display the same passenger information as on the touchscreen. Preferably, the mobile device is also configured to provide control and operating functionalities. In this context, the mobile device is specifically configured to display several buttons that can be operated by the passenger. For example, the mobile device can be configured so that a passenger can access various passenger information via the buttons displayed on the device. In other words, this means that the mobile device is configured so that a passenger can select which passenger information is displayed on the device using the buttons.Alternatively or additionally, the mobile device can also be configured so that a passenger can select which passenger information is displayed on the touchscreen using the buttons. Preferably, the mobile device is also configured to operate PSU functions. In particular, the mobile device can be configured so that a passenger can control or operate individual modules, especially functional components of the modules, using the buttons displayed on the mobile device. For example, the mobile device can be configured so that a passenger can control or operate the ventilation module, especially its functional components, using the buttons displayed on the mobile device.The mobile device can be configured to activate and deactivate the airflow, adjust the airflow strength, and / or set the position of the air outlet and thus the airflow direction. Alternatively or additionally, the mobile device can also be configured to control or operate functional components of the electronic module. For example, the mobile device can be configured to allow a passenger to control or operate the lighting system using the buttons displayed on the device.The mobile device can be configured so that a passenger can use the buttons displayed on the device to activate and deactivate the lighting system, in particular one or more light sources, and / or adjust the light intensity of one or more light sources, and / or adjust the area of ​​the passenger cabin illuminated by the lighting system. This offers the advantage of improved visibility of the content displayed on the mobile device for the passenger. Furthermore, operating PSU functions via the mobile device is easier for the passenger. In particular, both the operation of the PSU functions and the content displayed on the mobile device can be individually customized by the passenger.

[0036] In one possible configuration, the mobile device can also be configured for acoustic or audio output. Specifically, the mobile device can be configured so that audio output is provided via the mobile device's built-in speakers or via headphones or speakers connected to the mobile device via a wired or wireless connection. The mobile device is configured, in particular, so that a passenger can activate the acoustic output via a button. Preferably, the mobile device is configured so that a passenger can select, via a button, which content is to be output as acoustic output. In particular, the acoustic output can include speech output and / or a beeping sound.Preferably, the mobile device is configured to output content displayed on the touchscreen of the electronic module or on the display of the mobile device itself as speech output or a beep. For example, text content and / or symbols, such as safety symbols, can be output as speech.

[0037] In a further development, it is provided that the mobile device is set up to additionally display the speech output which is provided via the mobile device and / or the speaker of the PSU as text and / or as sign language on the display surface of the mobile device and / or on the display surface of the touchscreen.

[0038] In a further embodiment, the mobile device is also configured for communication between a passenger and the cabin crew. For example, the mobile device can be configured so that a passenger can request cabin crew or service personnel via a button displayed on the device. Additionally, the mobile device can also be configured so that the passenger can submit a specific or individual request to the cabin crew.

[0039] Preferably, the mobile device is configured so that all display content shown on the touchscreen of the electronic module is also displayed on the mobile device's display. In particular, the mobile device is configured to provide the same operating and control functionalities as the touchscreen. The mobile device is specifically designed as an optional or additional display and operating device and is not intended to replace the touchscreen.

[0040] This makes flight operations safer, as safety-relevant information is always accessible or permanently displayed or output. Furthermore, it also improves the handling and provision of passenger information. This particularly benefits people with disabilities such as visual or hearing impairments.

[0041] Additionally, the mobile device can be configured to allow passengers to save settings they have made on the device. For example, settings such as voice output, language, PSU function settings, etc., can be saved.

[0042] In other words, the task is accomplished by a modular power supply unit (PSU). Specifically, the modular PSU features an integrated screen, particularly an integrated touchscreen, for controlling the reading lights and displaying safety indicators. Additional displays are also possible, such as airline branding. The modular PSU is architecturally divided into three components: the air shower (ventilation module), the electronics (electronics module), and the oxygen supply (oxygen supply module). Furthermore, the modular PSU includes integrated loudspeaker technology (speakers), which can be designed as panel speakers or piezoelectric speakers.The modular PSU (Pulse Unit) comprises three main modules: an electronics module, an air shower module (ventilation module), and an oxygen module (oxygen supply module). The electronics module includes LED reading lights (light sources) and a display (screen, touchscreen), which is configured to display characters, control the reading lights, and initiate the PAX call.

[0043] The reading lights (lighting system) are designed as three light sources, each with a lens. Furthermore, the electronics module includes, in particular, an indicator for the initialized passenger call, preferably an LED located next to the display (touchscreen). The air shower (ventilation module) is designed to include three air outlets, preferably movable so that the position of the airflow can be changed. The oxygen module (oxygen supply module) includes, in particular, an oxygen generator and a mask container, as well as oxygen masks. The display is also designed to show logos, flight information, cabin crew service times, and subtitles for the deaf and hard of hearing.

[0044] The display is specifically designed as an integrated touchscreen. Preferably, the touchscreen is also configured for displaying safety signs and for controlling the reading lights via a touch function (software), as well as for controlling the PAX call indicator via a touch function (software). For improved visibility for passengers (especially in aisle seats) and / or enhanced ergonomics, the display is positioned at an angle to the direction of flight. The modular power supply unit (PSU) features a modular design for its electronic components (reading lights, touchscreen, speakers, PAX call indicator), the throttle component, and / or...

[0045] The system includes air showers (ventilation module) and an oxygen supply component or emergency oxygen (oxygen supply module). The loudspeaker technology is preferably based on piezoelectric loudspeaker technology. Furthermore, the loudspeaker particularly features a loudspeaker grille or is arranged beneath a loudspeaker grille, so that sound waves generated by the loudspeaker travel through the gaps in the grille towards a passenger. The reading lights are preferably based on LED technology. The control and power supply of the modular power supply unit (PSU) is preferably provided via cables or power rails (power line communication), e.g., via clip connections.

[0046] The touchscreen is preferably configured to display integrated safety indicators such as seatbelt signs and no-smoking signs. The touchscreen is also preferably configured for intuitive operation by a passenger, including the operation of the reading lights (e.g., dimming the reading lights) and the passenger call button.

[0047] Furthermore, the touch display (touchscreen) is also specifically designed for the following display options:

[0048] Safety indicators are animated and illustrated with scrolling text.

[0049] Announcements from cabin crew and pilots as scrolling text / subtitles, whereby the scrolling text / subtitles can be pre-programmed or automatically generated, e.g., by Kl.

[0050] Scrolling text display for hearing-impaired people and / or accessible color design for greater inclusion through improved communication with and integration of people with disabilities.

[0051] Animated safety indicators, e.g., fastening the seatbelt; direct feedback via display, e.g., whether the reading light is on or off, Pax Call button pressed.

[0052] In particular, the touch display (touchscreen) can also be configured to display additional information, including:

[0053] Boarding information (e.g. seat numbering)

[0054] Flight data (e.g., flight route, flight duration, destination information) In-flight program (e.g., menu / meal selection, service times, service information (e.g., restroom occupancy))

[0055] Information about inflight entertainment

[0056] News

[0057] Branding

[0058] Advertising

[0059] For example, the touchscreen can be configured to provide feedback after the PAX call button or buttons for activating the reading lights are pressed. Furthermore, the touchscreen can be configured to change the size of display icons during the display to draw a passenger's attention to them.

[0060] The modular power supply unit (PSU) is constructed from a minimal mix of materials to improve recycling, conserve resources, and simplify module repairs. Specifically, a minimal mix of materials means that the components are made only from engineering-grade plastics, silicone, and materials used for electronic components. This allows the material from the modular PSU to be reused at the end of its product life for the spacers between individual new modular PSUs in the cabin.

[0061] Furthermore, the modules are preferably attached to the base body by means of detachable connections, which allows for quick replacement in case of defects or repair and quick disassembly and sorting for recycling.

[0062] In one possible configuration, a Braille generator and / or a projector could be integrated into the modular power supply unit (PSU) as additional modules or extensions for the electronics module. Specifically, the modular PSU should be designed so that both the Braille generator and the projector share a single location within it. The customer (airline, OEM) can, for example, choose whether the Braille generator or the projector module is installed in the corresponding seat row. In particular, the Braille generator and the projector have identical dimensions and connections, allowing for flexible replacement between them, for example, in the event of a defect, by ground / service personnel during turnarounds or inspections.

[0063] The Braille generator is preferably configured for the following functions:

[0064] Greater inclusion through improved communication with and integration of people with disabilities (e.g., visual impairment, visual and hearing impairment, etc.)

[0065] Translation of the displayed information via output as Braille when a finger / touch surface is placed on it.

[0066] Display of safety signs (e.g. seatbelt sign switched on or off) Display of additional information

[0067] Increased safety for disabled persons due to the constant possibility of accessing information about safety signs.

[0068] In particular, visually impaired people would no longer have to remember whether the conventional acoustic cabin signal to fasten their seatbelt had just sounded or whether it was already the signal to possibly unfasten their seatbelt.

[0069] The projector is preferably set up for projecting the following content:

[0070] Seat numbers are displayed on the back of the front seat during boarding, which can speed up the boarding process.

[0071] Display of additional information during the flight (e.g. branding / time)

[0072] In a further configuration, the Modular PSU (PSU) also features an interface for a mobile device (mobile terminal) or smartphone. This interface allows a passenger's mobile device to connect to the Modular PSU in a row of seats. For example, a smartphone, laptop, or tablet can be connected to the Modular PSU via this interface. The interface is designed for a wireless connection between the mobile device and the Modular PSU, and this connection can be established via Wi-Fi, Bluetooth, an app, scanning a QR code, or other connections and protocols.

[0073] In particular, the mobile device (mobile terminal) represents another module or extension of the electronic module of the modular PSU (PSU) by providing the control of the modular PSU (PSU) and other functions.

[0074] Control via a mobile device is preferred, but only optional and additional, and is not intended to replace direct control via the Modular Power Supply Unit (PSU). Specifically, all information and functions of the Modular PSU (control and dimming of the reading light, PaxCall button, etc.) that are displayed by default on the Modular PSU are also displayed and operated on the mobile device.

[0075] In particular, when the passenger call button is pressed, a menu could be made available on the mobile device, allowing the passenger to specify their request, which would then be displayed on a screen for the cabin crew. This would enable more efficient handling of medical emergencies. The mobile device could also provide additional information not displayed on the modular passenger information unit (PSU). Improved accessibility and reachability for passengers could be achieved through customizable language settings. A language setting could be configured on the mobile device, allowing all information, displays, and announcements to be delivered in the passenger's preferred language. Furthermore, passengers could individually configure the modular PSUs via their mobile devices to display additional information (excluding safety signs).Alternatively, passengers could customize the display on their mobile device, for example, by adjusting the arrangement of graphics or including additional information. These individual settings could also be saved in the app, allowing passengers to easily access their preferences on their next flight. Frequent flyers or people with disabilities would then only need to connect and quickly access their saved profile.

[0076] The mobile device (mobile terminal) or the wireless connection of the mobile device (mobile terminal) to the Modular PSU (PSU) can be configured, in particular, to repeatedly display all Modular PSU content and scrolling text on the mobile device (mobile terminal) in the language selected by the passenger. This allows for greater inclusion through improved communication with and integration of people with hearing impairments. Preferably, the mobile device (mobile terminal) is configured to play pre-generated subtitles during standard announcements. These subtitles can be generated and played back using AI for individual or spontaneous announcements by the cabin crew and / or pilots.

[0077] A setting on the mobile device could enable an audio output or read-aloud function for the displayed content, played through headphones connected to the mobile device. This audio output would allow visually impaired passengers to control light buttons and air vents. They could also receive information about safety signs and additional information (flight data, time, etc.), just like all other passengers. Visually impaired individuals would no longer need to remember whether the conventional seatbelt warning signal has just sounded or whether it's the signal to unbuckle. This would promote greater inclusion through improved communication with and integration of visually impaired passengers.

[0078] For passengers with physical disabilities, operating the Modular Passenger Unit (PSU) and the control buttons for lights, passenger call, etc., is made easier by using a smartphone (mobile device). If, due to their disability, they cannot reach the Modular PSU or can only reach it with difficulty by stretching their arms or standing up, they can use their smartphone (mobile device) and thus have the same options as people without disabilities. This can lead to greater comfort for all passengers and greater inclusion through improved communication with and integration of people with physical disabilities.

[0079] The modular power supply unit (PSU) is specifically designed to allow for an interface with passengers' smartphones (mobile devices). Passengers can connect to the modular PSU from their seat row, for example, by holding their smartphone (mobile device) against a reader on the unit, using an app, or by scanning a QR code. This allows them to customize the PSU and control it via their smartphone. The smartphone interface is intended to be optional; that is, all controls and selection options should also be accessible directly on the modular PSU's touchscreen.

[0080] In particular, the connection between the smartphone (mobile device) and the Modular-PSU (PSU) is set up so that, after connecting the smartphone (mobile device) to the Modular-PSU (PSU), the passenger can then select what should be displayed via the smartphone (mobile device).

[0081] For example, flight data, service / meal times, weather, etc., could be displayed there—information currently unavailable on aircraft without individual entertainment systems. The lights could also be switched on and off. Additional functions would include dimming the brightness and electrically adjusting the light direction. Controlling the air vents, including airflow and possibly temperature, via smartphone (mobile device) would also be conceivable. The passenger call button could also be accessed via smartphone (mobile device). Passengers could then select or enter their request. This message could subsequently appear on a display for the flight attendants, thus reducing service time and distances. For example, a passenger could select the option to order a beverage.The interface with the smartphone and expanded selection options also offer further advantages for people with disabilities.

[0082] For blind or visually impaired individuals, an audio output or readout of the displayed content could be offered via a setting on their smartphone (mobile device). This could then be played back through headphones connected to the smartphone (mobile device) or the modular PSU, or at a lower volume through the speakers on the modular PSU itself. This audio output would allow visually impaired individuals to control light buttons and air vents (ventilation module). They could also receive information via NS / FSB signs, as well as optional information (flight data, time, etc.), just like all other passengers. Furthermore, visually impaired individuals would no longer need to remember whether the conventional seatbelt warning signal has just sounded or whether it is already the signal to unbuckle.

[0083] For deaf or hard-of-hearing individuals, subtitles or sign language interpretation of announcements can be selected via the display (touchscreen) of the Modular PSU (PSU) or a smartphone (mobile device). The subtitles / sign language interpretation can then be displayed on the smartphone or the Modular PSU. For standard announcements, previously generated subtitles can be played by default. Subtitles for individual or spontaneous announcements made by cabin crew / pilots can be generated and played using KL (presumably a software program).

[0084] For passengers with physical limitations, operating the Modular PSU (Pulse Unit) and the control buttons for lights, air, etc., is made easier by using a smartphone (mobile device). If, due to their limitations, they cannot reach the Modular PSU or can only do so with difficulty by stretching their arms or standing up, they could use smartphone operation and thus have the same options as people without limitations. The individual settings of the Modular PSU could also be saved via a smartphone app. Frequent flyers or people with disabilities would then only need to connect and quickly access their saved profile. The smartphone interface should ideally be optional.All controls and selection options should also be directly accessible via the touchscreen on the Modular Power Supply Unit (PSU). The additional personalized information and the accessibility for people with disabilities regarding the operation of the Modular PSU and the provision of personalized information offer significant added value.

[0085] This allows for the individualization of the Modular Passenger Storage Unit (PSU) for airlines and passengers, as well as the provision of customer-specific and optimized information. Furthermore, it enables improved services and enhanced safety for people with disabilities. Additionally, greater convenience can be achieved by operating the entire Modular Passenger Storage Unit (PSU) via smartphone (mobile device) without the need for awkward arm stretching or arm movements over other passengers.

[0086] The Modular Passenger Unit (PSU) is specifically designed so that passengers can customize its display via a touchscreen. For example, the PSU can display flight information, service / meal times, and other relevant data. Furthermore, the PSU allows passengers to control the lighting (including brightness) and air vents (including airflow and, if applicable, temperature). The touchscreen also provides additional accessibility features for people with disabilities. These include Braille on the edge of the PSU, transparent overlays on the touchscreen (where buttons for air, calls, etc., can be located), and an audio output, enabling operation for visually impaired individuals.Especially for deaf people, announcements could be displayed in sign language / subtitles via the display (touchscreen).

[0087] The touchscreen can be configured to allow passengers to individually select what information is displayed on the modular power supply unit (PSU). For example, flight data, service / meal times, weather, etc., could be displayed – information not currently available on aircraft without individual entertainment systems. The touchscreen can also be configured to control the cabin lights. Additional functions include dimming the light brightness and electrically adjusting the light direction. Controlling the air vents, including airflow and potentially temperature, via the touchscreen is also conceivable. Furthermore, the passenger call button is accessed via the touchscreen, allowing passengers to select or enter their request.The PAX Call Button can be configured so that the message subsequently appears on a display (touchscreen) for the flight attendants. This would allow the flight attendants to reduce service time and distances. For example, the passenger could select the option to order a drink.

[0088] An expanded display (touchscreen) and enhanced selection options also offer advantages for people with disabilities. For blind or visually impaired individuals, a Braille indicator could be placed either to the side of the touchscreen or overlaid on the touchscreen itself. This would allow them to control light buttons and air vents (ventilation module) or access flight information. With Braille displayed next to the touchscreen, the positions of the individual buttons (light, air, passenger call) would be predefined. Using the overlay, the airline could align the buttons and place the Braille indicator in the appropriate location on the touchscreen. Additionally, an audio output could be enabled for visually impaired passengers via a setting on the Modular PSU (Passenger Control Unit).The system could offer to read aloud the displayed content. This could then be played back via headphones connected to the Modular Power Supply Unit (PSU) or, at a lower volume, via the speakers on the Modular PSU itself. Visually impaired passengers could also use this system to control light buttons and air vents (ventilation module). Furthermore, they could receive information via NS / FSB signs, as well as optional information (flight data, time, etc.), just like all other passengers. Visually impaired individuals would also no longer need to remember whether the conventional audible seatbelt warning signal has just sounded or whether it is already the signal to unbuckle.

[0089] For deaf or hard-of-hearing individuals, subtitles or sign language interpretation of announcements could be selected via the Modular PSU's touchscreen. The subtitles / sign language interpretation could then be displayed on the Modular PSU. For standard announcements, previously generated subtitles could be played by default. Subtitles for individual / spontaneous announcements by cabin crew / pilots could be generated and played using AI. The additional individualized information and the accessibility for people with disabilities regarding the operation of the Modular PSU and the provision of individualized information offer significant added value with this concept.

[0090] This allows for the individualization of the Modular Passenger Supply Unit (PSU) for airlines and passengers, as well as the provision of customer-specific and optimized information. Furthermore, it enables a better service and improved safety for people with disabilities.
