US Patent 9759530 Target impact sensor transmitter receiver system

A system for sensing the impact of a bullet on a target and remotely reporting the successful impact to the shooter by means of a signal transmitted from a sensor transmitter to a receiver incorporated with headphones, ear buds or an I-phone with Bluetooth capability. The sensor includes a wireless transmitter and a impact/vibration sensor such as a piezoelectric sensor. The target impact sensors can be used with various stationary targets such as metallic or paper targets, but can also be used on movable targets such as body armor worn by players in paint ball competition.
