Abstract
Abstract A gasket for electrical apparatus and the like, operation of which tends to generate or be adversely affected by electromagnetic and radio frequency interference (EMI/RFI), comprising a compressible, electrically conductive core. It may also comprise a flexible, electrically conductive, and substantially abrasion resistant sheath surrounding the compressible core. The apparatus may be sealed against EMI/RFI leakage, noise emission and environmental infiltration and the like.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
93 words
A conductive EMI shielding gasket comprising: (a) a core formed of a compressible conductive material; (b) a conductive layer extending over a surface of the core, the conductive layer being selected from the group consisting of conductive film, metal foil and conductive fabric; (c) a non conductive adhesive disposed between the surface of the core and the conductive layer for bonding the conductive layer to the core; and (d) the adhesive being disposed in an intermittent, discontinuous pattern over the surface of the core so as to maintain the conductivity of the gasket.
Claim 2
Dependent Claim
93 words
A conductive EMI shielding gasket comprising: (a) a core formed of a compressible conductive material; (b) a conductive layer extending over a surface of the core, the conductive layer being selected from the group consisting of conductive film, metal foil and conductive fabric; (c) a non conductive adhesive disposed between the surface of the core and the conductive layer for bonding the conductive layer to the core; and (d) the adhesive being disposed in an intermittent, discontinuous pattern over the surface of the core so as to maintain the conductivity of the gasket.
Claim 3
Dependent Claim
66 words
A conductive EMI shielding gasket comprising: (a) a core formed of a compressible conductive material; (b) a conductive layer extending over a surface of the core; (c) a non conductive adhesive disposed between the surface of the core and the conductive layer in an intermittent, discontinuous dot pattern for bonding the conductive layer to the core in a manner to maintain the conductivity of the gasket.
Claim 4
Dependent Claim
66 words
A conductive EMI shielding gasket comprising: (a) a core formed of a compressible conductive material; (b) a conductive layer extending over a surface of the core; (c) a non conductive adhesive disposed between the surface of the core and the conductive layer in an intermittent, discontinuous dot pattern for bonding the conductive layer to the core in a manner to maintain the conductivity of the gasket.
