Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
57 words
A shielding device, formed from a unitary planar member, for inhibiting the passage of electromagnetic radiation to and/or from circuit elements disposed on a substrate, comprising: a first portion adapted for mounting on a substrate surface, and a second portion displaceable relative to the first portion for allowing access to circuit elements disposed on the substrate surface.
Claim 2
Dependent Claim
25 words
A shielding device as claimed in claim 1, wherein the second portion is a cover displaceable by movement about its interconnection with the first portion.
Claim 3
Dependent Claim
