Patent Images
1. A smart explosive igniter comprising:
- a non electrically conducting substrate;
a semiconductor bridge (SCB) mounted on said substrate, said SCB having two electrical terminals;
a semiconductor switch mounted on said substrate adjacent said semiconductor bridge igniter, said switch having an input terminal, an output terminal, and a trigger terminal, said input terminal being electrically connected to said output terminal upon the application of a trigger signal to said trigger terminal;
output means for electrically connecting said output terminal to one of said SCB terminals;
connecting means for electrically connecting a SCB firing voltage between said switch input terminal and the other of said SCB terminals; and
trigger means for electrically connecting a trigger voltage between said switch trigger terminal and the other of said SCB terminals.
