1. Apparatus for desensitizing sensor elements which are mounted on protected articles, said apparatus comprising:

  • a sensor element detector;

    a scanning mechanism which moves said detector to produce a scan along a surface adjacent to which multiple sensor elements may be placed, the movement of the detector being in a direction such that, during said scan, said detector passes directly over each of said sensor elements in succession and successively detects the presence of each of said sensor elements;

    a sensor element desensitizing mechanism arranged to be operated to desensitize said sensor elements adjacent said surface; and

    a control apparatus connected to operate the desensitizing mechanism following a scan in response to the detection of a predetermined number of sensor elements during said scan.
