Abstract (en)
[origin: EP0287905A1] To deactivate a resonant target (E) only a single discharge pulse is sent out, which merely produces a crack signal instead of a vibration and destroys the target (E). As the energy source for providing the discharge pulse it is preferable to use a discharge capacitor (Cl) which is coupled in series with a transmitter aerial (Ll) and can be reversed in its charge via a circuit element (LDR, 1-5). <IMAGE>
