Passenger service unit and related systems
A passenger service unit (PSU) for a transport vessel has a unitary chassis with a plurality of apertures extending therethrough. Each one of the apertures is independently sized to receive at least one of a plurality of different modules. Each one of the modules includes one or more PSU fixtures having components different from other ones of the plurality of modules. A representative vessel is a passenger aircraft. Representative modules include vent and passenger reading light module, speaker module, passenger oxygen supply module and display module.
1. A passenger service unit (PSU) for a transport vessel, comprising:
a unitary chassis having a plurality of apertures extending therethrough with each aperture of the plurality of apertures independently sized to receive at least one of a plurality of different modules, wherein each one of the modules includes one or more PSU fixtures having components different from other ones of the plurality of modules;
wherein one of the plurality of modules includes both a passenger reading light and a gasper; and
wherein a second one of the plurality of modules includes an information display configured to receive an electromagnetic signal and to convert the electromagnetic signal to a human-recognizable display of information.
2. The passenger service unit of claim 1 wherein the information display communicates with sensors located in the vessel to display information useful to a passenger.
3. The passenger service unit of claim 1 wherein the information display includes at least one advertising icon.
4. A passenger service unit of claim 1 wherein a cabin sidewall washlight is disposed on an edge of the unitary chassis adjacent a sidewall of the vessel.
5. The passenger service unit of claim 4 wherein the cabin sidewall washlight is a light emitting diode (LED).
6. The passenger service unit of claim 4 wherein an edge of the unitary chassis opposite the sidewall of the vessel includes a multi-functional in-board lighting system.
7. The passenger service unit of claim 6 wherein the in-board lighting system is effective to simultaneously illuminate an attendant call light, illuminate a seat row marker and provide emergency exit lighting.
8. The passenger service unit of claim 1 wherein a light emitting projector extends from the unitary chassis and is effective to project information onto a sidewall of the vessel.
9. The passenger service unit of claim 1 wherein the information display is a touch screen display.
10. The passenger service unit of claim 9 wherein the touch screen display is configured to present information regarding available lavatories in response to a user input.
11. The passenger service unit of claim 9 wherein the touch screen display is configured to present a selectable attendant call icon.
12. A PSU for a commercial aircraft, comprising:
a chassis;
wherein the chassis has formed therein a plurality of receptacles configured to receive interchangeable modules; and
a projector effective to, when the PSU is installed in a passenger cabin, project an image through one of the plurality of receptacles and onto a sidewall of the passenger cabin.
13. The PSU of claim 12 wherein the image is seat row information.
14. The PSU of claim 13 wherein the seat row information is displayed in response to an attendant call.
15. The PSU of claim 12 wherein the image is an arrow directed to the nearest exit of the passenger cabin.
16. The PSU of claim 12 wherein the image is a textual message.
17. The PSU of claim 16 wherein the textual message indicates that passengers should fasten their seat belts.
18. The PSU of claim 16 wherein the textual message conveys timing information regarding a flight.
19. The PSU of claim 12 wherein the image indicates that an attendant call has been made.
20. The PSU of claim 19 wherein the image is displayed in response in an input indicating an attendant call.
21. The PSU of claim 12 wherein a sidewall light emitting diode washlight is integrated in a periphery of the chassis and effective to, when the PUS PSU is installed in a passenger cabin, illuminate at least a part of a side wall of the passenger cabin.
22. The PSU of claim 21 wherein the sidewall washlight is a white light suitable for low level lighting.
23. The PSU of claim 21 wherein the sidewall washlight is a colored light.
24. The PSU of claim 1 wherein the passenger reading light and the gasper are concentrically aligned with the passenger reading light circumscribing the gasper.
25. The PSU of claim 24 wherein the passenger reading light and the gasper are independently moveable relative to each other.
26. The PSU of claim 25 wherein the passenger reading light is a light emitting diode.
