The invention relates to a pulse technique and can be used in input and output devices.

The aim of the invention is to expand the scope by simplifying the sealing of the device.

The drawing shows the proposed device.

The device contains a sensor plate 1 with zones, rigid rods 2, seismic receivers 3, a support plate and a driver 3 of the signal, consisting of an amplifier-key block 6, a trigger 7, a relay 8 of time and a register 9.

The device works as follows.

To operate the device, it is necessary to apply a light blow to the sensor plate 1, for example, in the area of symbol B. The seismic signal propagates through the seismic channels through rods 2 and seismic receivers 3 to the plate. As a result of the propagation of seismic waves in seismic receivers 3, electrical signals are generated corresponding to the transmitted seismic waves. These signals are not the same due to differences in seismic wave trajectories. If 1 blow is applied in the zone of symbol B, then the corresponding seismic receiver will generate a signal earlier than the others, and the intensity of the first half period and the steepness of the first front of the electrical signal will be the highest for this channel. Electrical signals from the seismic receivers 3

to the input of the amplifier-key block 6, which, in its initial state, passes the signals to the triggers 7. When

any electrical signal is greater than the trigger level, the corresponding trigger is triggered, the time relay 8 is triggered and the corresponding character is written in register 9.

Time relay 8 closes the key portion of block 6, after which the electrical signals of the seismic receivers 3 do not reach the inputs of the trigger 7. After time ut, which can be adjusted, time relay 8 restores the key portion of block 6 to the initial state, and the device is ready to receive. symbol. In register 9, as a result of the impact, the symbol is processed, the zone of which is near the point of impact, i.e. the path of the seismoacoustic signal was the shortest.
