Patent ID: 8701559

Claim:
A system for use with a munition for detecting a target impact of the munition, the system comprising: a power supply having a mass-spring unit having an elastic element with one end connected to a mass and a second end connected to a piezoelectric material for generating power from one or both of an axial and lateral vibration of the mass-spring unit induced by the munition; and a processor operatively connected to the power supply for monitoring an output from the power supply and determining if the munition has one or both axially and laterally impacted a target based on the output; wherein the power supply comprises one or more axial power supplies and one or more lateral power supplies, each having a piezoelectric material for generating power from a lateral vibration induced by the munition and the processor operatively connected to the one or more lateral power supplies and one or more axial power supplies for monitoring an output from the one or more lateral power supplies and one or more axial power supplies and determining if the munition has one or more of laterally and axially impacted the target based on the output.
