Abstract

An information projection and control system for projecting information onto a projection area provided by a vehicle door, comprising at least one control unit that generates information, for projection onto the projection area; at least one projection device that projects the generated information onto the projection area; and at least one movement sensor that detects movements in a sensing area associated with the projection area, wherein the at least one control unit is adapted to control generation of the generated information on the basis of the detected movements.

First claim

What is claimed is:

1. An information projection and control system for projecting information onto a projection area provided by a vehicle door of a vehicle, the projection area being inside of the vehicle, comprising:
at least one control unit that generates information for projection onto the projection area inside of the vehicle,
at least one projection device that projects the generated information onto the projection area inside of the vehicle, and
at least one movement sensor that detects movements inside of the vehicle in a sensing area associated with the projection area inside of the vehicle, wherein the at least one control unit is adapted to control generation of the generated information on the basis of the detected movements inside of the vehicle and the at least one control unit is further adapted to adjust color, contrast, and/or brightness of the at least one projection device dependent on visibility and luminosity currently prevailing in respective surroundings of the vehicle door.

2. The information projection and control system of claim 1 ,
wherein the at least one control unit is further adapted to control operation of the vehicle door in response to the detected movements.

3. The information projection and control system of claim 1 , wherein the at least one projection device is mounted to the vehicle door.

4. The information projection and control system of claim 1 ,
wherein the generated information comprises at least one of pictures, symbols, text, videos, or live pictures.

5. The information projection and control system of claim 1 ,
wherein the generated information is related to at least one of a vehicle door status, entertainment and advertisement, a seat number scheme, instructions for passengers, or operation of the vehicle door.

6. The information projection and control system of claim 1 ,
wherein the generated information is related to maintenance of the vehicle door including dismantling and/or assembly instructions for the vehicle door.

7. The information projection and control system of claim 1 , further comprising:
at least one camera that is adapted to monitor respective surroundings of the vehicle door.

8. The information projection and control system of claim 1 ,
wherein the vehicle door comprises associated blocking and locking components which are electrically operable in response to the detected movements.

9. The information projection and control system of claim 1 ,
wherein the at least one control unit is connected to at least one first vehicle door and one second vehicle door and is adapted to generate information related to the first vehicle door for display on the second vehicle door.

10. The information projection and control system of claim 1 ,
wherein the vehicle is an aircraft, and the vehicle door is a cabin access door of the aircraft.

11. The information projection and control system of claim 10 ,
wherein the aircraft door is associated with an emergency slide, and wherein the generated information is intended to interdict opening of the aircraft door in normal operation mode of the aircraft as long as the emergency slide is in armed state.

12. The information projection and control system of claim 11 ,
wherein the at least one control unit is adapted to prevent the opening of the aircraft door in normal operation mode of the aircraft as long as the emergency slide is in the armed state, independent of the detected movements.

13. An aircraft with comprising:
at least one aircraft door; and
at least one information projection and control system for projecting information onto a projection area provided by the at least one aircraft door, the projection area being inside of the aircraft, each information projection and control system including:
at least one control unit that generates information for projection onto the projection area inside of the aircraft,
at least one projection device that projects the generated information onto the projection area inside of the aircraft, and
at least one movement sensor that detects movements inside of the aircraft in a sensing area associated with the projection area inside of the aircraft, wherein the at least one control unit is adapted to control generation of the generated information on the basis of the detected movements inside of the aircraft and the at least one control unit is further adapted to adjust color, contrast, and/or brightness of the at least one projection device dependent on visibility and luminosity currently prevailing in respective surroundings of the aircraft door.

14. A method of operating an information projection and control system associated with at least one aircraft door of an aircraft, wherein the information projection and control system includes at least one control unit, at least one projection device, and at least one movement sensor, the method comprising:
using the at least one control unit of the information projection and control system to generate information for projection onto a projection area of the at least one aircraft door inside of the aircraft,
using the at least one projection device of the information projection and control system to project the generated information onto the projection area of the at least one aircraft door inside of the aircraft,
using the at least one movement sensor of the information projection and control system to detect movements inside of the aircraft in a sensing area associated with the projection area of the at least one aircraft door inside of the aircraft,
controlling, by the at least one control unit, generation of the generated information on the basis of the detected movements inside of the aircraft, and
adjusting, by the at least one control unit, color, contrast, and/or brightness of the at least one projection device dependent on visibility and luminosity currently prevailing in respective surroundings of the at least one aircraft door.
