Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
82 words
An EMI/RFI shield for maintaining electrical conductivity across a junction between electrically conductive surfaces comprising: a. a wire mesh, having frayed, marginal edges for enhancing bonding of the screen to the conductive surfaces, locatable across the junction in electrical contact with the conductive surfaces; and b. at least one over coat of electrically conductive material for deposition on and through the screen for physically bonding the screen to the conductive surfaces and for maintaining electrical contact between the screen and said surfaces.
Claim 2
Dependent Claim
82 words
An EMI/RFI shield for maintaining electrical conductivity across a junction between electrically conductive surfaces comprising: a. a wire mesh, having frayed, marginal edges for enhancing bonding of the screen to the conductive surfaces, locatable across the junction in electrical contact with the conductive surfaces; and b. at least one over coat of electrically conductive material for deposition on and through the screen for physically bonding the screen to the conductive surfaces and for maintaining electrical contact between the screen and said surfaces.
Claim 3
Dependent Claim
14 words
The shield of claim 1, wherein the conductive over coat is formed from zinc.
