Abstract:
1. A system for the wireless detection of damage in a body armor ceramic plate, the system comprising: an interrogator, a body armor ceramic plate, wherein said interrogator includes an inductive primary coil having a resonant frequency and wherein said plate includes a corresponding inductive secondary coil adapted to cooperate with said primary coil when said interrogator is positioned in an interrogation position wirelessly adjacent said plate, and wherein, when in said interrogation position, said primary and secondary coils are inductively coupled in an inductive coupling when said primary coil is energized at said resonant frequency, and wherein said plate includes at least one self-contained frangible continuity circuit electrically connected to said secondary coil, wherein said inductive coupling induces an electrical current flow in said continuity circuit when said circuit is undamaged and thereby said plate has a non-damaged status, a detector cooperating with said primary and secondary coils when said interrogator is in said interrogation position, and wherein said detector detects said inductive coupling and wherein an indicator cooperating with said detector indicates said non-damaged status of said ceramic plate upon said detection of said inductive coupling, and wherein said ceramic plate and said self contained continuity circuit do not contain and do not have mounted thereon physical external electrical connectors external to said plate and electrically connected thereto.
