Abstract : The present invention relates generally to condition responsive electronic firing circuits and more particularly to an electronic circuit responsive to a predetermined change in supply voltage for producing a pulse of firing energy for firing a detonator. The present invention has particular application in the sterilization of mines which, in the past, has been carried out by mechanisms of a mechanical or electrochemical nature. These devices normally operate on a time basis and the mine may or may not be still active when the sterilization takes place. An active mine life equal to the life of the battery power supply associated therewith is usually desirable. Since precise battery life is impossible to predict under the wide range of operating conditions encountered, some means of sensing battery voltage continuously is necessary. The present invention is designed to accomplish this function by providing a means for sterilizing a mine at the end of the power supply life.
