  • Electrical pulse splitter for an explosives system
    Patent number: 9970742
    Abstract: There is provided an electrical pulse splitter (EPS) for an explosives system (10), the explosives system comprising an electrical pulse generator (EPG), the electrical pulse splitter (EPS), and first and second explosive charges (Ch1, Ch2) having respective first and second electrical initiators (D1, D2), The electrical pulse splitter (EPS) is configured to receive a primary electrical pulse from the electrical pulse generator (EPG), and to output first and second electrical pulses to the first and second electrical initiators (Ch1, Ch2) respectively. The second electrical pulse is output a length of time after the first electrical pulse is output, and the electrical pulse splitter is powered by the primary electrical pulse.
