PROJECTILE TARGET SYSTEM
First Claim
1. A projectile target comprising:
- a substantially sealed chamber having a front face and a spaced apart rear face with an enclosing side wall disposed intermediate, said front and rear faces being formed by membranes configured to allow a projectile to pass therethrough and to substantially seal to maintain said substantially seal chamber;
at least four spaced apart pressure wave sensors disposed within said chamber, said sensors configured to detect pressure waves created by said projectile;
a target controller in communication with said sensors and configured to receive signals therefrom indicative of the pressure sensed by said sensors wherein the time difference between receipt by said controller of signals from said sensors and discriminating with respect to sensor position to determine an impact point on said front face of said target such that said controller provides an output indicative of said impact point.

Abstract
According to one aspect of the present invention, a projectile target is disclosed comprising a target having a substantially sealed chamber having a front face and a rear face with an enclosing side wall disposed intermediate. The front and rear faces are formed by membranes configured to allow a projectile to pass therethrough and then substantially seal to maintain the substantially sealed chamber. Pressure wave sensors are disposed within the chamber and are configured to detect pressure waves created by the projectile. A target controller receives signals from the pressure sensors indicative of the pressure sensed by the sensors and determines an impact point of the projectile on the front face of the target.

26. A projectile target comprising:
-
a substantially sealed chamber having a front face and a spaced apart rear face with an enclosing side wall disposed intermediate, said front and rear faces being formed by membranes configured to allow a projectile to pass therethrough and to substantially seal to maintain said substantially seal chamber; a plurality of spaced apart pressure wave sensors disposed within said chamber, said sensors configured to detect pressure waves created by said projectile travelling within the chamber; a target controller in communication with said sensors and configured to receive signals therefrom indicative of the pressure sensed by said sensors wherein the time difference between receipt by said controller of signals from said sensors and discriminating with respect to sensor position to determine an impact point on said front face of said target such that said controller provides an output indicative of said impact point; and wherein said target controller is mounted to said target and movable between an in use position wherein the controller is moved clear of said target and a stowed position wherein the controller is adjacent to, contiguous with or disposed within said target.
