Abstract
Apparatus is disclosed which permits digital setting of resistance-capacitance (R-C) type fuzes, and which apparatus corrects for variations in timing due to deviation of capacitance values from nominal.
Claims6
Digital apparatus for setting the voltage across capacitor means, comprising:
- current source means for applying current pulses to the capacitor means, and initially applying a single current pulse to said capacitor means;
- converting means for converting the analog voltage across the capacitor means provided in response to the single current pulse to a corresponding digital output;
- computing means responsive to the digital output for computing the capacitance of the capacitor means and for providing a corresponding digital output;
- a pulse source for providing a fixed number of pulses;
- multiplying means connected to the computing means and to the pulse source for multiplying the fixed number of pulses from the pulse source by the digital output from the computing means and for providing a predetermined number of pulses;
- and
- the current source means connected to the last mentioned means and responsive to the predetermined number of pulses therefrom for applying a corresponding number of current pulses to the capacitor means for setting the voltage across the capacitor means.
