moreover, the device (1) is equipped with at least one transformer (3) designed to transfer at least one signal on at least one transmission means (5) of the communication protocol (6), inducing such electromagnetic interference. ## Claims ### Claim 1 A data interruption device between a plurality of control units communicating through at least one communication protocol, wherein the data interruption device is configured to produce an electromagnetic interference inhibiting a data communication between the plurality of control units, the device being equipped with at least one transformer configured to transfer at least one signal on at least one transmission means of the communication protocol, inducing the electromagnetic interference. ### Claim 2 (depends on 1) The device of claim 1, wherein the transformer is composed of at least one electric conductor wound on a first portion of the transformer, composing a primary winding of said transformer, and of at least one transmission means of the communication protocol wound on a second portion, composing a secondary winding of the transformer, enabling the transfer of the at least one signal, from the primary winding to the secondary winding, and generating the electromagnetic interference with a voltage value (Vs). ### Claim 3 (depends on 1) The device of claim 1, wherein the device is arranged in a means of locomotion and configured to inhibit the operation and/or the motility of the means of locomotion, during an action of a fraudulent getting hold of the means of locomotion. ### Claim 4 (depends on 1) The device of claim 1, further comprising: at least one managing unit designed to manage operation of the device; a case composed of a first portion and a second portion configured to be connected during transfer of the signal from the transformer on the transmission means of the communication protocol; and at least one control means, configured send and detect an activating and/or deactivating signal of the device by at least one user, and comprising a plurality of warning lights to indicate the correct operation of the control means, and a correct communication of the control means with the device. ### Claim 5 (depends on 2) The device of claim 2, wherein the secondary winding of the transformer comprises a single winding (Ns) of the transmission means on the second portion of the transformer. ### Claim 6 (depends on 2) The device of claim 2, wherein the primary winding on the first portion of the transformer comprises a number of windings (Np) obtained based on the supply voltage (Vp) of the device, the voltage value (Vs) of the electromagnetic interference, and the single winding (Ns) of the transmission means arranged on the second portion of the transformer according to Np=(Vp*Ns)/Vs. ### Claim 7 (depends on 2) The device of claim 2, wherein the first portion of the case is configured to contain the first portion of the transformer, the managing unit, and a supply means of the device. ### Claim 8 (depends on 2) The device of claim 2, wherein the second portion of the case is configured to contain the second portion of the transformer. ### Claim 9 (depends on 4) The device of claim 4, wherein the managing unit comprises: at least one driver to manage the primary winding on the first portion of the transformer; at least one sensor means to detect a possible change of position and/or inclination of the means of locomotion and/or a possible vibration of the means of locomotion; a central unit to manage the driver and the sensor means, and detect data related to the possible change of position and/or inclination of the means of locomotion, and to be interfaced with the control means; and a supply means. ### Claim 10 (depends on 1) A method for managing a data interruption device of claim 1 comprising: providing the device; activating the control means and verifying the connection between the control means and the device; communicating, between a control means and the device, a plurality of status and operation information; initiating an alert phase comprising: detecting, by the sensor means, a plurality of data related to positioning and/or inclination of the means of locomotion and/or detecting, by the sensor means a plurality of data related to vibration of the means of locomotion; sending the plurality of data to a central unit; comparing the plurality of data with at least one reference value indicating a correct positioning of the means of locomotion, and/or comparing said plurality of data with at least one threshold value indicating an allowed vibration value of the means of locomotion; if the result of said comparison is positive: repeating the alert phase; if the result of said comparison is negative: activating an alarm phase comprising: activating the transformer and generating the signal on the secondary winding of the transformer; generating the electromagnetic interference on the communication protocol; interrupting the data transmission between the plurality of control units; blocking the motility of the means of locomotion; and deactivating the device.
