Abstract

An apparatus adapted to provide visual attitude reference to occupants seated in an inboard area of a cabin of a vehicle, that includes at least one interior partition positioned in the cabin in proximity to the occupants and at least one video camera mounted on the vehicle for capturing an electronic image of an environment exterior to the vehicle. At least one video monitor is adapted to serve as a virtual window mounted on the at least one interior partition in a substantially vertical and substantially parallel direction relative to a direction of forward travel of the vehicle in viewing proximity to the occupant, and further adapted to receive the electronic image from the at least one video camera and provide to the occupant an image of the environment external to the vehicle to the occupant.

First claim

What is claimed is:

1. An apparatus adapted to provide attitude reference to occupants in a cabin of a vehicle comprising:
(a) a windowless suite positioned in the cabin having an opening and a plurality of interior partitions surrounding a seat;
(b) a plurality of video cameras mounted on the vehicle in a same lateral position as the windowless suite for capturing electronic images of an environment exterior to the vehicle;
(c) a plurality of video monitors adapted to serve as virtual windows mounted on the interior partitions in a vertical and parallel direction relative to a direction of forward travel of the vehicle in viewing proximity to the occupants, and further adapted to receive the electronic images from the plurality of video cameras and provide to respective occupants images of the environment external to the vehicle to the occupant;
(d) a computer connecting the plurality of video cameras with the plurality of video monitors;
(e) at least one sensor configured to provide occupant location data to the computer;
(f) wherein the plurality of video monitors are positioned in spaced-apart relationship along a longitudinal length of one of the interior partitions of the windowless suite of the cabin of the vehicle;
(g) wherein the computer utilizes occupant location data to determine the video images to be displayed on each of the plurality of monitors;
(h) wherein each of the plurality of monitors, based on the occupant location data as determined by the computer, displays a different image oriented in a direction perpendicular to an occupant's line of sight to the monitor displaying that image;
(i) wherein the line of sight originates at an occupant's eye position as estimated using sensors monitoring the position of the seat supporting the occupant, wherein the sensors are connected to the computer and provide the occupant location data to the computer; and
(j) wherein the different image displayed on each of the plurality of monitors provides a same field of view to the occupant of cabin as would be experienced by a similarly situated occupant through a window positioned in a lateral spaced-apart relationship along a longitudinal length of the vehicle.

2. The apparatus of claim 1 , wherein the plurality of video monitors are positioned in lateral proximity to the occupant.

3. The apparatus of claim 1 , wherein each image has a vertical angular field of view equal to the vertical angle subtended by the corresponding monitor from the occupants' eye position.

4. The apparatus of claim 1 , wherein the line of sight originates at the occupant's eye position while seated in a position required for taxi, takeoff and landing.

5. The apparatus of claim 3 , wherein the occupant's eye position is estimated using an optical system designed to locate the occupant's head, wherein the optical system is connected to the computer and provides the occupant location data to the computer.

6. The apparatus of claim 3 , wherein the occupant's eye position is estimated using a head rest sensor monitoring the position of the occupant's head on a head rest of the seat, wherein the head rest sensor is connected to the computer and provides the occupant location data to the computer.

7. The apparatus of claim 1 , wherein the suite is designed to seat a pair of occupants side-by-side.

8. An apparatus adapted to provide attitude reference to occupants in a cabin of a vehicle comprising:
(a) a windowless suite positioned in the cabin having an opening and a plurality of interior partitions surrounding a seat;
(b) a plurality of video cameras mounted on the vehicle in a same lateral position as the windowless suite for capturing electronic images of an environment exterior to the vehicle;
(c) a plurality of video monitors adapted to serve as virtual windows mounted on the interior partitions in a vertical and parallel direction relative to a direction of forward travel of the vehicle in viewing proximity to the occupants, and further adapted to receive the electronic images from the plurality of video cameras and provide to respective occupants images of the environment external to the vehicle to the occupant;
(d) a computer connecting the plurality of video cameras with the plurality of video monitors;
(e) at least one sensor configured to provide occupant location data to the computer;
(f) wherein the plurality of video monitors are positioned in spaced-apart relationship along a longitudinal length of one of the interior partitions of the windowless suite of the cabin of the vehicle;
(g) wherein the computer utilizes occupant location data to determine the video images to be displayed on each of the plurality of monitors;
(h) wherein each of the plurality of monitors, based on the occupant location data as determined by the computer, displays a different image oriented in a direction perpendicular to an occupant's line of sight to the monitor displaying that image;
(i) wherein the line of sight originates at an occupant's eye position as estimated using a head rest sensor monitoring the position of the occupant's head on a head rest of the seat, wherein the head rest sensor is connected to the computer and provides the occupant location data to the computer; and
(j) wherein the different image displayed on each of the plurality of monitors provides a same field of view to the occupant of cabin as would be experienced by a similarly situated occupant through a window positioned in a lateral spaced-apart relationship along a longitudinal length of the vehicle.

9. The apparatus of claim 8 , wherein the plurality of video monitors are positioned in lateral proximity to the occupant.

10. The apparatus of claim 8 , wherein each image has a vertical angular field of view equal to the vertical angle subtended by the corresponding monitor from an occupants' eye position.

11. The apparatus of claim 8 , wherein the line of sight originates at the occupant's eye position while seated in a position required for taxi, takeoff and landing.

12. The apparatus of claim 8 , wherein the occupant's eye position is estimated using sensors monitoring the position of the seat supporting the occupant, wherein the sensors are connected to the computer and provide the occupant location data to the computer.

13. The apparatus of claim 12 , wherein the occupant's eye position is estimated using an optical system designed to locate the occupant's head, wherein the optical system is connected to the computer and provides the occupant location data to the computer.

14. The apparatus of claim 8 , wherein the suite is designed to seat a pair of occupants side-by-side.
