Abstract
Abstract A three-dimensional television system having a view chamber with electrode vibration plates disposed above and below the viewing chamber with a plurality of minute particles moving rapidly back and forth between the vibration plates and illumination of selected of the particles provided at a desired height in the viewing chamber at a pluarlity of positions within the viewing chamber to provide a three-dimensional image based upon an image-sensing device's output directed to control the point of illumination within the viewing chamber.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
114 words
A three-dimensional television system comprising: a viewing chamber having a top and bottom, said viewing chamber also having a length, a depth and a height; first and second electrode plates positioned at the top and bottom of said viewing chamber; means to rapidly alternate a charge's direction between said first and second electrode plates; a plurality of minute particles formed in a narrow plane along the length and depth of said viewing chamber, said plane of particles moved by said alternating charge causing said particles to move rapidly in a plane between said first and second electrode plates; and means to illuminate selected of said particles at a desired position in said viewing chamber.
Claim 2
Dependent Claim
114 words
A three-dimensional television system comprising: a viewing chamber having a top and bottom, said viewing chamber also having a length, a depth and a height; first and second electrode plates positioned at the top and bottom of said viewing chamber; means to rapidly alternate a charge's direction between said first and second electrode plates; a plurality of minute particles formed in a narrow plane along the length and depth of said viewing chamber, said plane of particles moved by said alternating charge causing said particles to move rapidly in a plane between said first and second electrode plates; and means to illuminate selected of said particles at a desired position in said viewing chamber.
Claim 3
Dependent Claim
79 words
The device of claim 1 further including: image sensing means having an output; image processing means to convert said image sensing means, output into pulsing information and beam direction information; a beam source producing a beam sufficient to illuminate said particles directed by said pulsing information; beam aiming means directed by the beam direction information, said beam aiming means directing said beam on said first electrode plate at a position where it is desired to illuminate said selected particles.
Claim 4
Dependent Claim
56 words
The device of claim 2 wherein said top electrode plate is transparent and said pulsed beam is directed through said top electrode plate to strike in sequence selected particles in said plane of particles at a desired length, depth and particle height in said viewing chamber to illuminate said selected particles to form a visible image.
Claim 5
Dependent Claim
21 words
The device of claim 2 wherein said beam is of sequenced colors to create a colored image in said viewing chamber.
Claim 6
Dependent Claim
14 words
The device of claim 2 wherein said beam is produced by a laser device.
Claim 7
Dependent Claim
111 words
The device of claim 2 further including: top and bottom carbon electrode plates positioned respectively above and below said top and bottom electrode plates; a voltage source providing voltage to said carbon electrode plates at a voltage level just below that sufficient to cause a spark to jump between said carbon electrode plates; and said top carbon electrode plate adapted when struck by said beam to be locally heated thus reducing resistance at said heated spot to increase said spot's conductivity and causing a spark arc to pass between said carbon electrode plates at that spot, such spark arc ionizing said particles in its path causing them to generate visible light.
Claim 8
Dependent Claim
15 words
The device of claim 6 wherein said beam is produced by a cathode ray beam.
