Abstract: Electronics for a shock-hardened device, in particular a data recorder, incorporating non-volatile memory. The device has the functional elements: a signal conditioning circuit, an oscillator, an analog-to-digital converter (ADC), a field programmable gate array (FPGA), a trigger, and a non-volatile memory incorporating both electrically erasable programmable read only memory (EEPROM) and fast static random access memory (SRAM). As a recorder, the electronics enable efficient and reliable data recording in extreme shock environments, e.g., those involving dynamic testing of weapons such as target penetrating bombs or dual-stage warheads. It also provides for data retention upon loss or shutdown of power to the unit and yields high MTBF (mean time between failure) figures in more benign environments.

Abstract: Disclosed, in a preferred embodiment, is a switching circuit incorporating a Field Effect Transistor (FET), two series dual-tap gas tube surge arrestors, and high-voltage resistors as part of a high voltage switch of a fireset for initiating an exploding foil initiator (EFI). Until energizing the FET via a firing command, an operating voltage of 1000 V is held off by a combination of the surge arrestors and high-voltage resistors. Upon receipt of a firing signal, a 28 V source is used to energize the FET that, in turn, decreases the voltage across the one surge arrestor connected directly to ground and increases the voltage across the other surge arrestor. Upon reaching the breakdown voltage of the ionizable gas within the second surge arrestor, the gas ionizes, becomes electrically conductive, and dumps the second surge arrestor's voltage across the first surge arrestor. This causes the first surge arrestor to also break down. Both surge arrestors are now conducting.
