Patent ID: 7915898

Claim:
A system for transmitting information in environments capable of exposure to high level electro-magnetic fields, the system comprising: a first electronic unit; a second electronic unit; a cable disposed between and connecting said first electronic unit and said second electronic unit, said cable further comprising: a first wire; a dedicated surveillance conductor wire; an electrically conductive shield disposed around both said first wire and said dedicated surveillance conductor wire, means for injecting a signal onto the electrically conductive shield; means for monitoring a current flowing through the electrically conductive shield and determining whether said current is as a result of injection of a signal by said means for injecting a signal; and means for monitoring a voltage characteristic on said dedicated surveillance conductor wire and for making a determination as to a shielding capacity of said electrically conductive shield, wherein said means for injecting, said means for monitoring a current, and said means for monitoring a voltage in combination further comprises a shared shielding surveillance module disposed in said first electronic unit.
