Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
249 words
A system for flying drone aircraft from the ground entirely by remote control comprising: a drone aircraft; a first television camera mounted in said drone aircraft, an ultrawide angle lens mounted on said television camera; a second television camera mounted in said drone aircraft, a zoom lens mounted on said second television camera; means for transmitting signals from said first and second television cameras; means for receiving said signals from the first and second television cameras; means for producing and displaying a picture from said signals including a kinescope projector and a hemisphere with a treated surface to display the pictures received by said kinescope projector, wherein said kinescope projector projects onto the convex surface of sAid hemisphere for viewing from the concave side of said hemisphere; means to alternatively select the picture from either the first or second kinescope projector for showing upon said hemisphere; means to superpose the picture from the zoom lens television camera upon the image from said wide angle television camera such that the central area of the hemisphere displays the image scanned by the zoom lens television camera and the remainder of the hemisphere displays the image scanned by the wide-angle lens television camera; and a set of remote controls operatively connected to the flight controls of the drone aircraft for flying said drone aircraft; so that a ground controller may view said picture and operate said remote flight controls in response to the pictures received from the first and second television cameras.
Claim 2
Independent Claim
249 words
A system for flying drone aircraft from the ground entirely by remote control comprising: a drone aircraft; a first television camera mounted in said drone aircraft, an ultrawide angle lens mounted on said television camera; a second television camera mounted in said drone aircraft, a zoom lens mounted on said second television camera; means for transmitting signals from said first and second television cameras; means for receiving said signals from the first and second television cameras; means for producing and displaying a picture from said signals including a kinescope projector and a hemisphere with a treated surface to display the pictures received by said kinescope projector, wherein said kinescope projector projects onto the convex surface of sAid hemisphere for viewing from the concave side of said hemisphere; means to alternatively select the picture from either the first or second kinescope projector for showing upon said hemisphere; means to superpose the picture from the zoom lens television camera upon the image from said wide angle television camera such that the central area of the hemisphere displays the image scanned by the zoom lens television camera and the remainder of the hemisphere displays the image scanned by the wide-angle lens television camera; and a set of remote controls operatively connected to the flight controls of the drone aircraft for flying said drone aircraft; so that a ground controller may view said picture and operate said remote flight controls in response to the pictures received from the first and second television cameras.
