Abstract

A passenger service unit is provided. The passenger service unit includes at least one projector configured to project an image onto one or more display surfaces, at least one sensor configured to indicate a current position of the one or more display surfaces, and a projector controller in communication with the at least one projector and the at least one sensor. The projector controller is programmed to receive a signal from the at least one sensor indicating a current position of a display surface and instruct the at least one projector to project at least one image onto the tray table based on the current position of the display surface.

Claims (96)

1. A projection unit comprising:

at least one projector configured to project an image onto one or more display surfaces;

at least one sensor configured to indicate a current position of the one or more display surfaces; and

a projector controller in communication with the at least one projector and the at least one sensor, wherein the projector controller is programmed to:

receive a signal from the at least one sensor indicating a current position of a display surface;

adjust at least one image to project based on the current position of the display surface;

instruct the at least one projector to project the adjusted at least one image onto the display surface based on the current position of the display surface;

receive a second signal from the at least one sensor indicating that the display surface has moved to a second position; and

instruct the at least one projector to adjust projection of the at least one image based on the second position of the display surface.

2. The projection unit of claim 1 , wherein the display surface is a tray table, wherein the signal further indicates that the tray table is deployed.

3. The projection unit of claim 2 , wherein the projector controller is further programmed to:

receive a second signal from the at least one sensor indicating that the tray table has been stowed; and

instruct the at least one projector to halt projection of images.

4. The projection unit of claim 1 , wherein the projector controller is further programmed to:

receive a second signal from the at least one sensor indicating a first position of an object on the display surface; and

instruct the at least one projector to adjust projection of the at least one image based on the first position of the object on the display surface.

5. The projection unit of claim 1 , wherein the projector controller is further programmed to:

receive a signal from the at least one sensor indicating that no passenger is in a corresponding seat; and

instruct the at least one projector to project an image including at least a seat number onto the display surface associated with the seat.

6. The projection unit of claim 1 , wherein the projector controller is further programmed to:

determine a current mode; and

determine the at least one image for the at least one projector to display based on the current mode.

7. The projection unit of claim 1 , wherein the projector controller is further programmed to:

receive an instruction that a passenger has turned on a reading light; and

instruct the at least one projector to transmit a projection of light onto at least a portion of a seat of the passenger.

8. The projection unit of claim 7 , wherein the projector controller is further programmed to:

receive a signal from the at least one sensor indicating a location of an object that a passenger desires to be illuminated; and

instruct the at least one projector to transmit the projection of light based on the location of the object.

9. The projection unit of claim 1 further comprising a gimbal and a mirror, and wherein the projector controller is further programmed to instruct the gimbal to adjust an orientation of the mirror to adjust a location of the projected at least one image.

10. The projection unit of claim 1 further comprising an aperture, wherein the at least one projector projects the at least one image through the aperture.

11. The projection unit of claim 1 , wherein the signal further includes a shape of the display surface, and wherein the projector controller is further programmed to adjust the at least one image to project based on the shape of the display surface.

12. A method for operating a projector system, where the method is implemented by a computing device comprising at least one processor in communication with at least one memory device, wherein the computing device is in communication with at least one sensor and at least one projector, the method comprising:

receiving, from the at least one sensor, a signal indicating a current position of a display surface;

adjusting at least one image to project based on the current position of the display surface;

instructing the at least one projector to project the adjusted at least one image onto the display surface based on the current position of the display surface;

receiving a second signal from the at least one sensor indicating a first position of an object on the display surface; and

instructing the at least one projector to adjust projection of the at least one image based on the first position of the object on the display surface.

13. The method of claim 12 , wherein the display surface is a tray table, wherein the signal further indicates that the tray table is deployed, and wherein the method further comprises:

receiving a second signal from the at least one sensor indicating that the tray table has been stowed; and

instructing the at least one projector to halt projection of images.

14. The method of claim 12 further comprising:

receiving a second signal from the at least one sensor indicating that the display surface has moved to a second position; and

instructing the at least one projector to adjust projection of the at least one image based on the second position of the display surface.

15. The method of claim 12 further comprising:

receiving a signal from the at least one sensor indicating that no passenger is in a corresponding seat; and

instructing the at least one projector to project an image including at least a seat number onto a display surface associated with the seat.

16. The method of claim 12 further comprising:

determining a current mode; and

determining the at least one image for the at least one projector to display based on the current mode.

17. The method of claim 12 further comprising:

receiving an instruction that a passenger has turned on a reading light; and

instructing the at least one projector to transmit a projection of light onto at least a portion of a seat of the passenger.

18. The method of claim 17 further comprising:

receiving a signal from the at least one sensor indicating a location of an object that a passenger desires to be illuminated; and

instructing the at least one projector to transmit the projection of light based on the location of the object.

19. A projection unit comprising:

at least one projector configured to project an image onto one or more display surfaces;

at least one sensor configured to indicate a current position of the one or more display surfaces; and

a projector controller in communication with the at least one projector and the at least one sensor, wherein the projector controller is programmed to:

receive a signal from the at least one sensor indicating a current position of a display surface, wherein the display surface is a tray table, wherein the signal further indicates that the tray table is deployed;

adjust at least one image to project based on the current position of the display surface; and

instruct the at least one projector to project the adjusted at least one image onto the display surface based on the current position of the display surface.

20. A projection unit comprising:
