Abstract: A system (1) for detecting and recording impacts produced by shock waves and/or by non-lethal projectiles on the surface of a target (2), includes: 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 target (2), and capable of receiving the signals generated by the said sensors (3i), detecting which of the 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 transceiver device (4).

Abstract: The invention concerns a pump for compressed gas for a replica weapon for the projection of balls, comprising: A cylinder (7) forming a gas retention compartment (72) and provided with a cylinder head (71) forming a lateral wall of the said retention compartment, said cylinder head comprising a central orifice (73) A gas ejection nozzle (9) having a first end opening into the retention compartment (72) and a second end opening into a barrel (1) of the replica weapon, and A piston (8) provided with a piston head (81) which is movable in the retention compartment and suitable for compressing the gas in the said compartment, in which, on the one hand, the piston head is conical in shape and, on the other, the cylinder head has the shape of a funnel, complementary to the conical shape of the piston head.
