US12768629 - Multi-atmospheric safe firing control circuit for wireless detonators and initiators

A multi-atmospheric safe firing control circuit for wireless detonators and initiators is disclosed. A low-voltage switch can transition from an open state to a closed state. An oscillating circuit activates when the low-voltage switch transitions to the closed state and the oscillating circuit provides alternating current to primary coils of a transformer. A doubling circuit coupled to a capacitor receives direct current from secondary coils of the transformer and multiples voltage for storage in the capacitor. A gas discharge tube coupled to the capacitor acts as a high-voltage switch by completing a voltage transfer from the capacitor to coupled electrical contacts upon reaching a preset voltage threshold.
