Apparatus is provided for monitoring vibrational activity proximate to a source of mechanical vibration. The apparatus includes a bridge rectifier which may be positioned proximate to the source, and which provides a voltage output when the source generates a pattern of mechanical vibrations of very low g-level over a brief time interval, such pattern comprising a low g-level vibrational pulse. The apparatus also includes an amplifier coupled to the bridge rectifier for amplifying the voltage output, and further includes a device responsive to the amplif...
Apparatus for monitoring vibrational pulse activity of an explosive detonator device, said vibrational pulse activity having generated when said explosive detonator is activated, said apparatus comprising: a diode bridge rectifier proximate to said explosive detonator device and acoustically coupled thereto for providing a voltage output when activations of explosive detonator device generates mechanical vibrations of very low g-level over a brief time interval, means coupled to said bridge rectifier means for amplifying said voltage output; timing means...
