Patent ID: 7055435

Claim:
A spacecraft ordnance system, comprising: a squib; a resistor, wherein said resistor has a unique resistance value, and wherein said resistor has a first end and a second end, said second end of said resistor being connected to ground, and said first end of said resistor being connected with said squib; a driver line, wherein said driver line has a first end and a second end, said first end of said driver line being connected with said squib, and wherein the combination of said driver line, said resistor, and said squib forms an extended squib having a unique resistance value; a driver unit having an output, wherein said output is connected with said second end of said driver line; test circuitry built into said driver unit that enables verification of correct connection of said squib with said output of said driver unit; and an ordnance harness cable, wherein said driver line is placed inside said ordnance harness cable.
