Abstract

The system, through the use of modulate waves, employs two modules, the first (called MoD. 2050) contains three transmitters and one receiver, while the second (called MoD. 2051) contains three receivers and transmitter. The model 2050 is addressed to the moving means and it is useful to send a call to the nearest receiver-transmitter; the second, model 2051, listens the first in calling and is provided of an instrument which confirms the straight line to follow until to reach the model 2050 which gave the call.

Description

DESCRIPTION of the invention that is called :

Radio tracing system to locate a transmitter.

SUMMARY

The system through the use of modulate waves employs two moduls, the first(called MoD. 2050) contains three transmitters and one receiver, while the second( called MoD.2051) contains three receivers and transmitter.

The model 2050 is addressed to the moving means and it is useful to send a call to the nearest receiver-transmitter; The second, model 2051 listens the first in calling and is provided of an instrument which confirms the straight line to follow until to reach the model 2050 which gave the call.

DESCRIPTION

The system foresees

The model 2050 3(THREE) TX, 1(ONE) RX

" " 2051 3(THREE) RX , 1(ONE)TX

" " 2051 1(ONE) RX, 1(ONE) TX automatic with code specifies: the abbreviate word TX (TRANSMITTER)

" " " RX (RECEIVER )

To make the comprehension easier we call TX 1 2 3 and so on, in this way we will follow the employ and the functions.

The model 2050 is addressed to the moving means, to which it will aid to send a call to the nearest 2052, in continous listening.

The 2050 puts in action the TXl and the 2052 having received TXl automatically informs the coordination centre with the s

ries of RX.TX of its disposition, on his part, informs the operative centre , the nearest, to the call station that the call code has declaired.

The operative centre is provided of model 2051, instrument useful to the research, and that is movable to set up on the appropiate mean when it needs, so the research starts.

The 2051 on its device is provided of a street-map visor, of a good magnetic compass and an acustic and optic system.

To come in a Known zone it is ready to follow some straight lines that the device suggests ando also it listen the TX1 of calling, putting the instrument in edge in approaching it confirms the straight line to follow, until it reaches LOVER that 2051 confirms.

Now the operator is just in the best conditions to give the certain coordinates valuing the compass, the street-map and th point 2052 of which we know the exact position. The operation that follows the 2051 is to send an impulse to the 2050 to switch the TX1 off and automatically gives the"go on" to the TX2 of 2050, moving by hand the 2051 to receive The TX2 and now it knows surely that it is at about 25 Km. from the call point, because the optimal autonomy (vectorial) of TX1 is of 50 Km. of radius.

It repeats the operation just done before and also in this case, following the straight line on which it is prepared it will have LOVER of TX2, it repeats, sending another impulse to the 2050 switch the TX2, giving automatically the "go on" to TX3 and now it is surely at more or less 1 Km. of radius from the cAll-point, it follows the straight line where it is connected until to reach the 3°rd LOVER that in this case is at 2 mt. from the call point.

NEEDS/CLAIMS

1- THE SYSTEM ALLOWS TO INDICATE THE POSITION OF THE POINT

FROM WHICH IT HAD TRANSMITTED THE CALL THROUGH THE TRANSMITTER DEVICE MOD. 2050.

2- THE RESEARCH OCCURS THROUGH THE USE OF MODULATE RADIOS-WAVES TRANSMITTED ON THREE FREQUENCES THAT START IN PROGRESSION DURING THE MOVABLE MEAN PROVIDED OF THE RECEIVER MOD.2051 APPROACHES TO THE CALL6POINT.

Claims

3- IT IS CLAIMED THE ORIGINALITY OF THE STRUCTURE OF THE

MODELS (described in the enclosed form and then the using system of the radio-modulate waves to determine the approac

to a call point. 4- AS RESEARCH OF TYRE MEANS AND THEIR RELATIVE LOCATION AND POSITION

5- THE EMPLOYMENT AS ANTI-THEFT FROM A BIG DISTANCE ON THE

CHARACTERISTICS GIVEN AT THE MOMENT OF EMPLOYMENT.

INTRODUCTION TO A CRITERION R.A. R.I. O.R.

First Part

Model TRX 2050

In order to explain my projected system R.A. R.I. O.R.

I feel proper to give you some details:

The system foresees:

The model 2050 ' 3(three) TX,1(one) RX

" " 2051 3(" ) RX,1( " ) TX

" " 2052 1( one) RX , 1 ( " ) TX

automatic with code

specifies : the short-word TX (TRANSMITTER)

" " " RX ( RECEIVER ) to make the comprehesion easier we will call TX 1 2 3 and so on, in order to follow the use and the functions.

The model 2050 is addressed to the moving means to which it will aid to send a call to the nearest 2052, in continous listening.

The 2050 moves to action the TX1 and the 2052 receiving automatically TX1 informs the cohordination centre with the series of RX, TX to his arrangements, that in his turn, informs the nearest operative centre to the call-station than the call-code has declaired.

The operating centre is provided of the model 2051, display that attends to the research; and that is movable, to set up on the most appropiate means, then the research starts. The model 2051 on his display is provided of a visor

of finder-street map of a good magnetic compass and of

an optical and acoustic system.

To go into the new zone it starts to follow some straight lines that the instruments suggests, it ears as well the TX-ca connecting in coming the board instruments it confirms the straight line to follow until it reaches LOVER that the model 2051 confirms it.

Now the operator is in the best conrition to give surely some right co-ordinates, to look at the compass, the finder stree map and the point 2052 of which he knows now where it is.

The following operation of the model 2051 is to send to the model 2050 an impulse to switch the TX1 off and automatically it gives the "go on" to TX2 of 2050, it gets ready by hand the model 2051 to receive the TX2,and now it knows certainly that it is at about 25Km. from the call-point because th optical autonomy (vectorial) of TX1 is of 50 Km. of radius.

It repeats the operation that it has done beforehand also in this case, following the straight line on which it is placed, it surely will find itself to meet LOVER of TX2,it repeats to send another impulse to 2050 switch the TX2 off, giving automatically the "go on"to the TX3 and now surely to more or less 1 Km. of radius from the call-point, it follows the straigh line where it is connected, until to reach the 3rd over in this case at 2.mt from the call point.

Hoping to have explained in a sufficient way everything after giicing the opportunity to find a needle in a big straw/
