1. An all-fire detection circuit for an electrically initiated inertial igniter munition, the all-fire detection circuitry comprising:
an input configured for generating an input voltage over a duration responsive to an acceleration of the munition; an electrical storage device configured to receive a portion of the input voltage over the duration and to thereby accumulate a charge, an output coupled to the electrical storage device; a first diode having a first anode coupled to the input and a first cathode coupled to the electrical storage device; a comparator configured to compare a voltage at the output and a reference voltage and to produce a result based on the comparison; and a voltage divider circuit coupled between the electrical storage device and the output, the voltage divider providing a portion of the charge to the output; wherein the voltage divider circuit comprises a first resistor and a second resistor coupled in a series connection between the first cathode and a ground potential and the output is coupled to the series connection between the first and second resistors; and the comparator is a first comparator, the result is a first result, and the voltage divider circuit comprises a third resistor in the series connection with the first resistor and the second resistor, the circuit comprising a second comparator coupled to the series connection between the second and third resistors, the second comparator configured to compare a voltage between the second and third resistors and a reference voltage to produce a second result based on the comparison. |
