Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
203 words
In an aircraft simulator training device wherein an image is presented on a television display, the improvement comprising: a first display; a first vidicon arranged to transmit an image to said first display; optical elements comprising an entrance pitch prism rotatably mounted in a first bearing, an objective lens, a path folding prism, an aspheric lens, a first path folding mirror, a second path folding mirror, a lower projection lens, a first zoom lens system, said optical elements being rotatably mounted in a second bearing, and arranged in an optical path to transmit an image from said entrance pitCh prism to said first vidicon; control means for controlling rotation of said rotatably mounted optical elements in said optical path to simulate pitch, change in azimuth, and yaw, in said image; a dove prism in said optical path rotatably mounted in a third bearing, means whereby said control means control rotation of said dove prism to simulate roll in said image; and means whereby said control means control rotation of said dove prism to eliminate undesired rotation of said image caused by operation of said rotatably mounted optical elements in said optical path to simulate pitch, change in azimuth, and yaw, in said image.
Claim 2
Dependent Claim
203 words
In an aircraft simulator training device wherein an image is presented on a television display, the improvement comprising: a first display; a first vidicon arranged to transmit an image to said first display; optical elements comprising an entrance pitch prism rotatably mounted in a first bearing, an objective lens, a path folding prism, an aspheric lens, a first path folding mirror, a second path folding mirror, a lower projection lens, a first zoom lens system, said optical elements being rotatably mounted in a second bearing, and arranged in an optical path to transmit an image from said entrance pitCh prism to said first vidicon; control means for controlling rotation of said rotatably mounted optical elements in said optical path to simulate pitch, change in azimuth, and yaw, in said image; a dove prism in said optical path rotatably mounted in a third bearing, means whereby said control means control rotation of said dove prism to simulate roll in said image; and means whereby said control means control rotation of said dove prism to eliminate undesired rotation of said image caused by operation of said rotatably mounted optical elements in said optical path to simulate pitch, change in azimuth, and yaw, in said image.
Claim 3
Dependent Claim
59 words
The apparatus of claim 1, and including a second display, a second zoom lens system, a second vidicon, and switch means whereby said image can be selectively transmitted from said first vidicon to said first display via said second display, said second zoom lens system, and said second vidicon, or directly from said first vidicon to said first display.
