ABSTRACT:
A method and system for accurate timing in a low current system useful in fuzing applications generates a first count of oscillations of an oscillator of unknown frequency during a first period of unknown duration. A second count of oscillations of the oscillator is generated during a second period of a known duration. The duration of the first period is calculated based on the first count and the second count. A solid-state, thin-film battery is able to be used by virtue of low-current characteristics of the system, enabling extended shelf life for fuzing systems.
