Abstract:
A miniature arming device having an armed state and an unarmed state, comprising:a MEMS ignition device for producing a pyrotechnic output at a first location in response to application of an electric signal; pyrotechnic output control means, having an armed state and an unarmed state, for routing said pyrotechnic output from said first location to a second location when in said armed state and blocking said pyrotechnic output from said second location when in said unarmed state; a substrate, said substrate supporting said MEMS ignition device and said control means; and wherein said pyrotechnic output control means comprises: a channel for communicating a pyrotechnic output, said channel having an input and an output; a pyrotechnic barrier, said pyrotechnic barrier normally blocking said channel; and an electromagnet for moving said pyrotechnic barrier to unblock said channel when said electromagnet is energized, wherein a pyrotechnic output may pass through said channel to said second location.
