Classification: CPC B  F  G | IPC B  F  G

Claim 10:
11. A component for a munitions system comprising:
a signal generator for generating a signal;
a resonant circuit having a resonant frequency and operably connected to receive the signal from the signal generator and to provide an output;
a monitor operably connected to monitor the output of the resonant circuit; and
an indicator operably connected to the monitor and configured to indicate that the output of the resonant circuit has changed, wherein
the resonant circuit is configured so that its resonant frequency changes when a conductor or other inductance-influencing object moves relative to the component;
wherein the monitor is further configured to monitor the resonant frequency of the resonant circuit over a period of time, and use the detected changes in the resonant frequency to determine movement of a conductor or other inductance-influencing object relative to the component, wherein using the detected changes to determine whether the conductor or other inductance-influencing object has moved relative to the component comprises determining the separation distance and/or angle of separation between the component and the conductor or other inductance-influencing object.
