Abstract
Abstract A radiation and static electricity suppression device is disclosed that is formed of a mesh fabric having at least some of the yarns capable of conducting electricity. The mesh is affixed to a frame that serves to conform the mesh to the surface of a cathode ray tube. A grounding connection is included to ground the mesh to the chassis of the cathode ray tube. The mesh when grounded supresses the static field and significantly reduces electro-magnetic radiation emanating from the CRT circuitry and passing through the opening in the CRT housing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
73 words
A radiation and static electricity suppression device for a cathode ray tube comprising: a fine mesh fabric in which at least some of either the warp or weft fibers are electrically conductive and further that the electrically conductive fibers are generally evenly distributed across the mesh; said fine mesh fabric conformable to the viewing surface of the cathode ray tube; means for electrically connecting said electrical conductive fibers with said cathode ray tube.
Claim 2
Dependent Claim
73 words
A radiation and static electricity suppression device for a cathode ray tube comprising: a fine mesh fabric in which at least some of either the warp or weft fibers are electrically conductive and further that the electrically conductive fibers are generally evenly distributed across the mesh; said fine mesh fabric conformable to the viewing surface of the cathode ray tube; means for electrically connecting said electrical conductive fibers with said cathode ray tube.
Claim 3
Dependent Claim
37 words
The radiation and static electricity suppression device of claim 1, wherein the means for electrically connecting the fibers with the cathode ray tube includes a flexible frame conformable to the display surface of the cathode ray tube.
Claim 4
Dependent Claim
40 words
The radiation and static suppression device of claim 2 wherein the fine mesh fabric is formed of a synthetic material and further wherein the electrically conductive fibers of the mesh fabric are of a synthetic material having electrically conductive properties.
Claim 5
Dependent Claim
19 words
The radiation and static electricity suppression device of claim 1 or claim 3 wherein the fibers are essentially non-reflective.
Claim 6
Dependent Claim
24 words
