Abstract
Abstract A visual display simulator is described wherein a scene is viewed by a pinhole lens element which casts images of the scene on a fiber-optic bundle for transmittal to a T.V. camera tube unit of a closed circuit T.V. having a display unit viewable by a trainee. The pinhole lens element is positionable by a roll, pitch, and yaw drive means about three orthogonal axes intersecting at the pinhole, and is also positionable in translation by other drive means.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
207 words
A visual display simulator comprising: a scene viewable from one side and having at least two dimensions; pinhole lens means for viewing said scene; roll, pitch, and yaw drive means supporting said pinhole lens means and operative tO position said pinhole lens means about roll, pitch, and yaw axes which are orthogonal and intersect at the entrance pupil of said pinhole lens means; translation drive means connected to said roll, pitch, and yaw means for effecting translational movement of said pinhole lens means with respect to said scene; a T.V. camera tube unit comprising a scanning tube; flexible fiber-optic image conducting means having one end connected to receive images through said pinhole lens means and having the other end coupled to said scanning tube; T.V. display means connected to said camera tube unit and operative to display images corresponding to the view of said scene by said pinhole lens means; a trainee station including controls operable by a trainee; computer means responsive to said control means to provide roll, pitch, and yaw and translational drive command signals; said roll, pitch, and yaw drive means and said translational drive means being responsive to said command signals to position said pinhole lens means in roll, pitch, yaw, and translation.
Claim 2
Dependent Claim
207 words
A visual display simulator comprising: a scene viewable from one side and having at least two dimensions; pinhole lens means for viewing said scene; roll, pitch, and yaw drive means supporting said pinhole lens means and operative tO position said pinhole lens means about roll, pitch, and yaw axes which are orthogonal and intersect at the entrance pupil of said pinhole lens means; translation drive means connected to said roll, pitch, and yaw means for effecting translational movement of said pinhole lens means with respect to said scene; a T.V. camera tube unit comprising a scanning tube; flexible fiber-optic image conducting means having one end connected to receive images through said pinhole lens means and having the other end coupled to said scanning tube; T.V. display means connected to said camera tube unit and operative to display images corresponding to the view of said scene by said pinhole lens means; a trainee station including controls operable by a trainee; computer means responsive to said control means to provide roll, pitch, and yaw and translational drive command signals; said roll, pitch, and yaw drive means and said translational drive means being responsive to said command signals to position said pinhole lens means in roll, pitch, yaw, and translation.
Claim 3
Dependent Claim

A visual display simulator comprising: a scene viewable from one side and having at least two dimensions; pinhole lens means for viewing said scene; roll, pitch, and yaw drive means supporting said pinhole lens means and operative tO position said pinhole lens means about roll, pitch, and yaw axes which are orthogonal and intersect at the entrance pupil of said pinhole lens means; translation drive means connected to said roll, pitch, and yaw means for effecting translational movement of said pinhole lens means with respect to said scene; a T.V. camera tube unit comprising a scanning tube; flexible fiber-optic image conducting means having one end connected to receive images through said pinhole lens means and having the other end coupled to said scanning tube; T.V. display means connected to said camera tube unit and operative to display images corresponding to the view of said scene by said pinhole lens means; a trainee station including controls operable by a trainee; computer means responsive to said control means to provide roll, pitch, and yaw and translational drive command signals; said roll, pitch, and yaw drive means and said translational drive means being responsive to said command signals to position said pinhole lens means in roll, pitch, yaw, and translation.
Claim 5
Dependent Claim
222 words
A visual display simulator as defined in claim 1, and wherein said roll, pitch, and yaw drive means comprises: a first member having a base portion and two spaced side portions extending from the base portion; bearing means supporting said member for rotation about said yaw axis; a first reversible motor and gear means connected to said member for effecting said rotation; a second member comprising a plate portion disposed between said side portions of said first member and having trunnion shaft means extending therefrom, said shaft means being journalled in said side portions for rotation of said second member about said pitch axis, said plate portion having a partial circular cut-out defined therein; a third member comprising a block rotatably disposed in said cut-out and having a semi-circular groove accommodating the edges of said plate portion defining said cut-out, said third member being rotatable about said roll axis; a second reversible motor and gear means mounted on one of said side portions and connected to said shaft means for effecting said rotation of said second member about said pitch axis; a third reversible motor and gear means mounted on said second member and connected to said third member for effecting said rotation thereof about said roll axis; and said pinhole lens means being mounted on said third member for movement therewith.
