Abstract
A pulse source powers a wand-like probe with spaced contacts that is arranged to be applied to and drawn along the surface of a surveillance tag that contains a diode semiconductor with exposed terminals. When the probe contacts engage the diode terminals, current is passed through the diode sufficient to destroy its unidirectional conducting characteristics and thereby deactivate the tag. A cut-out circuit is included to prevent the passage of excessive current through the diode or damaging short-circuiting of the power amplifier output.
