Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
156 words
A multifunctional integrated circuit card adapted for insertion into and withdrawal from an electrical apparatus, said card comprising: a circuit substrate having a plurality of integrated circuit chips mounted thereon, a connector mounted along one peripheral edge of said substrate and providing means for electrically connecting the circuit substrate and said integrated circuit chips mounted thereon to an electrical apparatus. ground pads disposed on said substrate and electrically connected to said connector. a housing of insulative material enclosing said circuit substrate, said housing formed of a top portion and a bottom portion which join together along a peripheral seam adjacent the periphery of said circuit board, and a U-shaped conductive member disposed within the joined top and bottom housing portions adjacent said seam, said U-shaped periphery of said circuit substrate except for a portion of said peripheral edge where said connector is mounted, each end of said U-shaped member connected to one of said ground pads.
