Abstract : The patent relates to a ferroelectric ceramic ring transducer assembly for reliably sensing projectile impacts upon a target surface. The transducer is mounted by a single hole in the target to allow unimpeded vibration at the resonance frequency. In addition, the ring is designed to have a resonance frequency which matches the compressional impact shockwave to guard against false readings.
