  • Transmitter coil, improved fuze setter circuitry for adaptively tuning the fuze setter circuit for resonance and current difference circuitry for interpreting a fuze talkback message
    Patent number: 6176168
    Abstract: Improved transmitter coil, improved fuze setter circuitry for adaptively tuning the fuze setter circuit for resonance and current difference circuitry for interpreting a fuze talkback message. The transmitter coil utilizes an “L” shaped coil cross section, with the wrapped coil portion being at right angles to the return coil portion, in order to increase the coupling efficiency between the fuze setter coil and the fuze receiver coil, as compared to the prior art “C” coil. The inventive “L” shaped cross section also eliminates counter magnetic field due to the return coil portion being at right angles to the wrapped coil portion. The fuze setter includes circuitry for adaptively tuning the resonant LC circuit for resonance by adjusting the capacitance in the LC circuit to maximize current in the LC circuit. The fuze setter utilizes a switched capacitor network circuit to tune the LC circuit for resonance.
