Method and system for presenting different views to passengers in a moving vehicle
First Claim
1. A system for presenting an image in a vehicle as the vehicle rotates about a rotation axis, the system comprising:
- a signal receiving portion configured to receive a first signal corresponding to an image of a first view from a position located a first distance from the rotation axis, the first view encompassing a first viewing area; and
a signal processing portion configured to direct to a display portion located a second distance from the rotation axis a time-varying second signal, the time-varying second signal representing a second view, the second view being a portion of the first view and occupying a second area less than the first area, wherein the location of the second area relative to the first area is selected based at least on an amount by which the first and second distances differ.

Abstract
Systems and methods for presenting images in a vehicle as the vehicle rotates about a rotation axis are disclosed. In one embodiment, the system includes a signal receiving portion that receives a first signal corresponding to an image of a first view from a position located a first distance from the rotation axis. A signal processing portion directs to a signal display portion located a second distance from the rotation axis, a time varying second signal that represents a second view. The second view can be a portion of the first view and can occupy an area less than the area occupied by the first view. The location of the second area relative to the first area can be selected based at least on an amount by which the first and second distances differ.

7. A system for presenting images corresponding to views external to a vehicle as the vehicle rotates about a rotation axis, the system comprising:
-
an Image source positioned a first distance from the rotation axis and being configured to transmit a time-varying first signal as the vehicle rotates, the first signal representing a first view external to the vehicle, the first view encompassing a first viewing area;
a display portion positioned within the vehicle at a second distance from the rotation axis, the second distance being different than the first distance; and
a processing portion coupled between the image source and the display portion, the processing portion being configured to receive the first signal from the Image source and transmit a time-varying second signal to the display portion, the second signal representing a second view external to the vehicle, the second view being a portion of the first view and occupying a second area less than the first area, wherein the location of the second area relative to the first area depends at least in part on an amount by which the first and second distances differ. - View Dependent Claims (8, 9, 10, 11)

20. A system for presenting an image in a vehicle as the vehicle rotates about a rotation axis, the system comprising:
-
image receiving means for a first signal corresponding to an image of a first view from a position located a first distance from the rotation axis, the first view encompassing a first viewing area; and
processing means for processing the first signal, the processing means being coupled to the image source means to receive the first signal and direct to a display portion located a second distance from the rotation axis a time-varying second signal, the time-varying second signal representing a second view, the second view being a portion of the first view and occupying a second area less than the first area, wherein the location of the second area relative to the first area is selected based at least on an amount by which the first and second distances differ. - View Dependent Claims (21, 22)

23. An aircraft rotatable about a rotation axis, comprising:
-
a fuselage portion;
a wing portion depending from the fuselage portion;
a propulsion system coupled to at least one of the fuselage portion and the wing portion;
a signal receiving portion configured to receive a first signal corresponding to an image of a first view from a position located a first distance from the rotation axis, the first view encompassing a first viewing area; and
a signal processing portion configured to direct to a display portion located a second distance from the rotation axis a time-varying second signal, the time-varying second signal representing a second view, the second view being a portion of the first view and occupying a second area less than the first area, wherein the location of the second area relative to the first area is selected based at least on an amount by which the first and second distances differ.

24-30. -30. (Cancelled) 31. A method for presenting an image in a vehicle, comprising:
- while the vehicle rotates about a rotation axis;
receiving a first signal corresponding to an image of a first view from a position located a first distance from the rotation axis, the first view encompassing a first viewing area; and
directing a second signal to a display portion of the vehicle, the display portion being positioned a second distance from the rotation axis;
wherein when the first distance differs from the second distance, directing the second signal includes directing the second signal to represent a time-varying second view, the second view being a portion of the first view and occupying a second area less than the first area, with the location of the second area relative to the first area being selected based at least on an amount by which the first and second distances differ.
- while the vehicle rotates about a rotation axis;
-
32. The method of claim 31 wherein the second distance is less than the first distance, wherein the first area has a first centroid and wherein the second area has a second centroid, further wherein the first centroid rotates at a first rate about the rotation axis, still further wherein directing the second signal includes directing the second signal to form a second area having a second centroid that rotates at a second rate about the rotation axis, the second rate being less than the first rate.
-
33. The method of claim 31, further comprising receiving a third signal corresponding to a motion of the vehicle about the rotation axis.
-
34. The method of claim 31 wherein the second distance is less than the first distance, the first area has a first centroid and the second area has a second centroid, further wherein directing the second signal includes directing the second signal to form a second area having the second centroid positioned closer than the first centroid to the rotation axis.
-
35. The method of claim 31 wherein the first area has a first centroid and the second area has a second centroid, further wherein the first centroid rotates at a first rate about the rotation axis, still further wherein directing the second signal includes directing the second signal to form an image having a second area with a second centroid that rotates at a second rate about the rotation axis, the second rate being proportional to the second distance divided by the first distance.
-
36. The method of claim 31 wherein the first viewing area subtends a first viewing angle and wherein the second viewing area subtends a second viewing angle less than the first viewing angle.
-
37. The method of claim 31 wherein the vehicle includes an aircraft having a longitudinal roll axis and wherein the rotation axis is at least approximately the same as the roll axis.
