Would someone please describe the NASA Standard Detonator?

I did work for Hercules in the early 60s on electroexplosive
devices (EEDs).  State of the art then was a 1 watt/1 amp
no-fire device, and the considerably more expensive exploding
wire device.  It really is a tricky business to get something
to ignite only when you intend it to.  Maybe there hasn't been
any progress, and that's why they still use mechanical safe/arm
equipment.
