ABSTRACT:
An electro-mechanical detection system for measuring the point of impact of a missile such as a sports projectile on a target and for measuring the velocity and force of impact. The detection system is contained in a large plastic envelope, on which a target is displayed and in one embodiment, the detector is a wire or plastic grid that is instrumented to measure changes in stress in the individual grid elements that occur when the missile impacts the target. In another form of this invention, the detector is embedded in an elastomeric mat contained within the plastic envelope with electrical conductors within the mat subject to movement in a magnetic field when the mat compresses in response to the impact of a missile on the target. In either form of the invention, suitable electronic circuitry is used to convert the signals generated at impact to a display.
