CLAIMS
1. System (1) for detecting and recording impacts produced by shock waves and/or by non-lethal projectiles on the surface of a target (2) , characterized in that it comprises:
a) a plurality of sensors (3i) applied to the target (2) and capable of detecting the said impacts and generating and transmitting a signal detectable by a transceiver device (4);
b) a transceiver device (4), also fixed to the said target (2), and capable of receiving the signals generated by the said sensors (3i) , detecting which of the said sensors has emitted a signal, and sending the corresponding data to a recording apparatus (5);
c) a recording apparatus (5) capable of recording and storing the data received from the said transceiver device (4) .
2. System according to Claim 1, in which the said recording apparatus (5) is also provided with means for displaying the data sent to it by the said transceiver device (4) on an image reproducing the profile of the said target (2) and the positions of the said sensors (3i) on it.
3. System according to any one of the preceding claims, additionally comprising one or more transmitters (6) for sending a signal, detectable by the said transceiver device (4), which in terms of range and intensity simulates the effects of the explosion of an explosive device.
4. System according to any one of the preceding claims, suitable for the case in which the said non-lethal projectiles are fired by an electrically operated rifle (7), in which the said transceiver device (4) and/or the said recording apparatus (5) are provided with means for disabling the said rifle (7) when one or more sensors (3i) of a target (2) detect one or more impacts produced by a non-lethal projectile or by the simulated shock wave of an explosion.
5. System according to any one of the preceding claims, in which the said sensors (3i) are of the piezoelectric type, are distributed over the surface of a jacket (2) , and are connected to the transceiver device (4) in such a way as to transmit to it the voltage which is generated in the jacket.
6. System according to Claim 5, in which each sensor (3i) is applied to a rigid plate (13i) fixed on the corresponding target (2) .
7. System according to any one of the preceding claims, in which the signals transmitted by the transceiver device (4) to the said recording apparatus (5) are radio signals.
