System for avoiding the collision of a moving body with other objects

Claim 3

A system according to claim 1 wherein said storing means is a video tape recorder for storing in a video tape information on the other objects including the approaching dangerous objects and information on the subject moving body.

Claim 4

A system according to claim 1 wherein said storing means is a photographic film for recording pictures photographed by a camera from the images of the subject moving body and the other objects including the approaching dangerous objects which are displayed on the screen of a radar image indicating tube.

Claim 5

A system according to claim 3 wherein said photo film has a path of travel which extends between a feed reel and a takeup reel, and in which there is provided a plurality of projectors spaced longitudinally along the path of travel of said photo film and projecting onto a common screen the pictures recorded in said photo film, said common screen constituting said superposing means.

Claim 6

A system according to claim 1 wherein both said displaying means and said superposing means are combined in a multi-gun tube comprising a plurality of electron guns and deflectors, said multi-gun tube displaying on a single screen a plurality of images of the subject moving body and the other objects including the approaching dangerous objects aT the present and past moments.

Claim 7

A system according to claim 1 wherein said storing means comprises a scan converter tube including a write-in cathode ray tube for forming the images of the subject moving body and the other objects including the approaching dangerous objects and a read-out cathode ray tube for generating video signals representing the images on said write-in cathode ray tube; and a video tape recorder for recording on a video tape video signals from said read-out cathode ray tube.

Claim 8

A system according to claim 6 wherein there are further provided a plurality of reproducing video tape recorders spatially disposed along the passage of said video tape recorded with the video signals from said scan converter by said recording video tape recorder; and a plurality of television receivers for displaying on their screens respective images corresponding to the video signals reproduced from said reproducing video tape recorders and for projecting on a common screen the respective images displayed on said television receivers, said common screen constituting said superposing means.

Claim 9

A system according to claim 1 wherein said first image picture displaying means comprises a cathode ray tube.

Claim 10

A system according to claim 1 wherein said second image picture displaying means comprises a cathode ray tube.

Claim 11

A system according to claim 1 wherein said first and second image picture displaying means comprises cathode ray tubes, and said superposing means comprises a translucent mirror for superposing the first and second image pictures by said both displaying means thereof.

Claim 12

A system according to claim 10 wherein both said cathode ray tubes respectively are a visible storage tube scanned by a first scanning line for displaying the images on the screen and also by a second scanning line used for their erasure, said second scanning line preceding said first scanning line.

Claim 13

A system according to claim 10 wherein said cathode ray tube for said first image picture displaying means and said cathode ray tube for said second image picture displaying means are each provided respectively with a means for distinguishing the separate images displayed on the screens of the both cathode ray tube.

Claim 14

A system according to claim 10 wherein both said cathode ray tubes display the images on their respective screens by a system of denoting their relative motions and relative bearings and are each provided at least on the outside with at least a means for switching the system of indication over to one exhibiting their relative motions and true bearings.

Claim 15

A system according to claim 1 wherein said second picture displaying means and said replacing means are combined as a storage tube display having an input source of actual information supplied, during times when a trial operation is not being conducted, with the actual past information obtained through said storing means on the subject moving body as well as on the other objects including the approaching dangerous objects, and has an input source of a forecast information supplied during the time a trial operation is being conducted, and with a simulating trial information formed by the estimated information instead of that part of the actual past information component representing the subject moving body included in the actual information input source.

Claim 16

A system according to claim 14 wherein said actual information input source for said storage tube display comprises a multiplier which is supplied with a signal representing the actual past speed of the subject moving body obtained through said storing means and is designed to determine the distance to be displayed on said storage tube display through which the subject moving body traveled in the past; and a resolver coupled with said multiplier, supplied with a signal representing the actual past bow bearings of the subject moving body obtained through said storing means and adapted to generate two signal components resolved into a horizontal componenT and a vertical component, and wherein said forecast information input source for said storage tube display comprises another multiplier which is supplied with a signal representing a speed of the estimated information and is designed to determine the distance to be displayed on said storage tube display through which the subject moving body is supposed to have traveled in the past; and another resolver coupled with said another multiplier, supplied with a signal representing bow bearings of the estimated information which the subject moving body is supposed to have traveled in the past and adapted to generate two signal components resolved into a horizontal component and a vertical component, said two horizontal components and two vertical components from said both resolvers being independently subjected to relative vector summing upon the simulating trial operation so as to drive the off center coil assembly of said storage tube display through a switch closed upon the trial operation.

Claim 17

A system according to claim 15 wherein both said multipliers comprise a plurality of serially connected resistors and a switch means for changing over the terminals of said resistors.
