The signal input of the valve 19 is connected to the output of the delay circuit 77, and the control input 2 is through the shaper 13 with the iC-gene ator 7. The output of the valve 19 is connected to the encoder 21 and through the Inverter 20 g to the control input 2 of the valve 18, the signal | which is connected to the output of the delay circuit 16. The output of the ventilation valve 18 is connected to the .00 by the second input 1 of the x 21, connected through the communication channel 22 of the equipment of the athlete with the judicial registrar.

The prick fixer works as follows.

When injected into the body area of athlete A, protected by jacket 3 in equipment of Oportomeya B, a short circuit of inductor 8 of inductive D: atch1ka through metal occurs: T1eirovanny, nakamka jacket 3 athlete L and a signal appears at output of shaper 13 (time diagram 3 ). The former 13 generates a signal when the sensor inductance 8 of the sensor 8 is short-circuited through a conductive surface into which the injection was made (if the oscillations of the oscillator / generator 7 were interrupted). When the oscillations of the LC-oscillator 7 are disrupted, the output of the frequency discriminator 10 will be a zero level. At the outputs of the imaging unit // and 12 circuits OR 15 and the outputs of the delay circuits 16, 17 there will also be a zero signal. When a certain pressure is reached and when the injection is injected, the sensors are activated: to pressure 6, a sigial appears on the output of the former 14. The former 14 generates a standard oypna-l (Triggered by the pressure sensor 6 and serves to eliminate the “bounce” effect of mechanical contact in pressure sensor 6. When pressure sensor 6 is triggered, valve 19 opens, since both of its control inputs contain signals produced by the formers 13 and 14. The signal from the output of delay circuit 17 passes to the output of valve 19 (corresponds to a serious injection / remote control), and then through an encoder 21 and a connection 22 and a judicial recorder 1. The valve 18, when injected into jacket 3, is closed by the second control input with a signal from the inverter 20 and therefore the formation of a signal corresponding to an invalid one ) not happening.

When injected into an unprotected jacket 3 and mask 4 areas of the athlete’s body, there is no short circuit of the inductance 5. Therefore, there is no signal at the output of the imaging unit 13 and the valve 19 will be closed for this injection. The parameters of the inductance coil 8 iri of this prick do not change as compared with the initial state, since there are no M. materials near it that have magnetic properties or high electrical conductivity. The frequency of the LC oscillator 7 does not change; therefore, the output of the frequency discriminator 10 will be a zero signal level. At the output of the imaging unit // and the delay circuit 16 there will be also a zero signal, which corresponds to a thrust into the non-metallic, non-magnetic and surface. When pressure sensor 6 is triggered, and therefore with io. At the output of the imager 14, the valve 18 opens and the signal from the output of the delay circuit 16 passes to the output of the valve 18, then through the encoder 21 n communication channel 22 to the referee recorder /, where it is classified as an invalid prick.

When injected into mask 4, which contains a well-conducting coating, the oscillations of the /, C-generator 7 occur due to the short-circuit of the inductance 8 through the metal of the mask 4, and, consequently, the signal appears at the output of the imager 13. However, until the oscillations break LC-reHepaTOpa 7, when the inductive sensor is in the vicinity of the mask surface, the inductance value of the coil, inductance 8 decreases, which leads to an increase in the frequency of the LC ator 7. The frequency also changes at the output of the frequency discriminator 10 l of a signal. In this case, at the output of the imaging device 12 and, therefore, at the output of the OR 15 circuit, a voltage level other than zero appears. When the oscillations of the LC generator 7 are interrupted, the signals at the output of the formulas 1-2 and the circuit OR 15 are lost, but the delay circuit 17 remembers this signal for a time sufficient for the pressure sensor 6 to operate. When the pressure sensor 6 and the output of the generator 14 are triggered a signal appears, closes the junction 19, and a high voltage level from the output of the delay circuit 17 passes to the output of the valve 19. The signal at the output of the valve 19 in this case is different from the signal when the needle is pushed into the jacket 3, therefore the encoder 21 does not produce remote control signal. At the same time, on the output of the delay circuit 16 there is an ongaal, which is compatible with a HU, and when opening the valve 18 to the signals from the driver 14, the encoder 21 extracts the signal of the HL and passes it through the communication channel 22 to the referee recorder 21 .

When injected into weapon 5 into fencing track 2 with a soft metal coating, a short circuit of inductance 8 also occurs. In the immediate vicinity of the weapon, the frequency of the LC generator changes and a signal appears at the exit of the frequency discriminator 10, therefore , a signal appears at the output of the driver 11 and at the output of the delay circuits 16 and 17 (time diagrams 6, 8). In this case, both valves 18 and 19 are at the moment when the signal of the pressure sensor 6 appears at the output of the former 14 are closed. In this situation, no injection is recorded.

When injected into the fencing track 2, which has an insulating coating made of; the material of the soft material, everything happens as in the previous situation, with the only difference being that the short inductor coil did not happen.

Thus, when injected into any part of the athlete's equipment, including the metal part, the signal provided by the fencing rules appears at the exit of the thrusting device.

The positive effect of the proposed puncture fixer in comparison with the known loop antenna placed on the jacket, connected to the encoder through a three-dimensional antenna and a device that matches the signals from the encoders of both athletes in the judges ’recorder is improving the accuracy of fixing the injections and simplifying the equipment of the athletes due to the use of a mask with a coating of a metal with a high electrical conductivity, the use of which is currently used in the electric fixture ah of punctures by the rapier of the jacket ( Without a moisture-proof lining), unlike electrophores equipment, unrelated electric cells with equipment placed on the athlete, and two contacts at the end of the sensor, reduce the volume and weight of the equipment located by the athlete (there is no receiver with a high-quality and bulky filter, screens), mind: Efficient energy consumption from the power source by the equipment placed on the sport shift, i.e. using a smaller power source and, consequently, smaller dimensions, increasing the annaspa noise immunity Typbi by eliminating a loop antenna and a receiver connected to it.
