Abstract

Abstract A device, which when used while viewing the lighted images appearing on a television screen, reproduces said images with but a minor loss in light intensity, free of scan lines and harsh lines that are tiring to the eye when viewed over a prolonged period of time, with the reproduced images presenting a sense of depth relative to one another that is not apparent in the images seen on a television screen when viewed without the device. When the viewing device of the present invention is used while watching images appearing on a television screen, the device may be adapted to filter out all harmful radiation emitted by the television set towards the viewer, as well as remove infrared light from the reproduced images, which infrared light is also tiring to the eyes. The device while illustrated and described in conjunction with a television screen, is equally applicable for use with any concavo-convex surface on which an image is defined.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 304 words
A device that when interposed between a television screen and the viewer is capable of magnifying the lighted image on said screen and imparting a sense of depth of said magnified image to the viewer, said screen having a convex exterior surface, said device including: a. forward and rearward concavo-convex lens in laterally spaced relationship that are axially aligned with said screen and in front thereof, which lens are formed from a transparent rigid resin that transmits substantially all colors of the visible spectrum, said lens having the convex surface thereof exteriorly and oppositely disposed to one another, with said convex surface of said forward lens being most adjacently disposed to the viewer and of substantially the same curvature as the forward face of said screen; b. means for sealingly connecting the peripheral edges of said forward and rear lens and cooperating with said lens to define a confined space therebetween; c. a transparent liquid organic dispersion that fills said confined space and comprises a first dispersed phase in the form of a plurality of small globules of a transparent organic liquid, said small globules acting as a plurality of lens, and a dispersing phase in the form of a transparent liquid that is immiscible with said liquid defining said globules, with said liquid defining said dispersing phase and said liquid defining said globules having different indexes of refraction, with said image on said screen when viewed by said viewer through said forward and rear lens and said organic dispersion being magnified as to size and being visible as a plurality of magnified virtual images that appear to be in spaced depth relationship to one another due to the light from said image on said screen being refracted to different degrees as it passes through said lens, said dispersing phase and said dispersed phase.
Claim 2
Independent Claim 304 words
A device that when interposed between a television screen and the viewer is capable of magnifying the lighted image on said screen and imparting a sense of depth of said magnified image to the viewer, said screen having a convex exterior surface, said device including: a. forward and rearward concavo-convex lens in laterally spaced relationship that are axially aligned with said screen and in front thereof, which lens are formed from a transparent rigid resin that transmits substantially all colors of the visible spectrum, said lens having the convex surface thereof exteriorly and oppositely disposed to one another, with said convex surface of said forward lens being most adjacently disposed to the viewer and of substantially the same curvature as the forward face of said screen; b. means for sealingly connecting the peripheral edges of said forward and rear lens and cooperating with said lens to define a confined space therebetween; c. a transparent liquid organic dispersion that fills said confined space and comprises a first dispersed phase in the form of a plurality of small globules of a transparent organic liquid, said small globules acting as a plurality of lens, and a dispersing phase in the form of a transparent liquid that is immiscible with said liquid defining said globules, with said liquid defining said dispersing phase and said liquid defining said globules having different indexes of refraction, with said image on said screen when viewed by said viewer through said forward and rear lens and said organic dispersion being magnified as to size and being visible as a plurality of magnified virtual images that appear to be in spaced depth relationship to one another due to the light from said image on said screen being refracted to different degrees as it passes through said lens, said dispersing phase and said dispersed phase.
Claim 3
Dependent Claim 16 words
A device as defined in claim 1 wherein said first dispersed phase comprises a mineral oil.
Claim 4
Dependent Claim 56 words
A device as defined in claim 1 wherein said first dispersed phase comprises a plurality of different mineral oils, with each of said oils being of a different specific gravity, and with each of said mineral oils defining said globules that are different in size from said globules defined by the other of said mineral oils.
Claim 5
Dependent Claim 23 words
A device as defined in claim 2 wherein said dispersing phase comprises a liquid selected from a group consisting of turpentine and benzene.
Claim 6
Dependent Claim 20 words
A device as defined in claim 2 wherein said mineral oil comprises substantially 70 percent by volume of said dispersion.
Claim 7
Dependent Claim 31 words
A device as defineD in claim 5 wherein substantially 30 percent of said dispersion comprises a liquid dispersing phase of a liquid selected from the group consisting of benzene and turpentine.
Claim 8
Dependent Claim 80 words
A device as defined in claim 1 in which said first means includes; d. a frame in which an opening of a cross section at least as great as that of said screen is formed, with said first and second lenses sealing engaging the forward and rear portions of said opening; and e. second means for supporting said frame and lenses in a substantially vertical position forwardly of said, with said opening and lenses in axial alignment with said surface.
