<p>Activation device for electric and/or electronic user devices (50) comprising first electronic processing means (12, 1 12) associated with the electric or electronic user device (50) to be activated, and second electronic processing means (24) associated with one or more users enabled to use the electric and/or electronic user device (50). The second electronic processing means (24) are selectively connectable to the first electronic processing means (12, 1 12) in order to determine the enablement to use the electric and/or electronic user device (50). The first electronic processing means (12, 112) comprise first generator means (18) to generate a first pseudo-aleatory signal; the second electronic processing means (24) comprise second generator means (29) to generate a second pseudo- aleatory signal. The device comprises comparison means (32), connected on one side both to the first electronic processing means (12, 1 12) and also to the second electronic processing means (24) so as to receive the first and second pseudo- aleatory signal, and on the other side connected directly or indirectly to the electric and/or electronic user device (50) to be activated. The comparison means (32) transform, in a predetermined way, the first pseudo-aleatory signal and the second pseudo-aleatory signal, so as to generate at an exit (38) thereof a desired electric feed signal of the electric and/or electronic user device (50).</p> |
