Abstract: The invention relates to a hardware architecture of an ignition and/or injection managing system (1) for an internal combustion engine (2), of the type structured to cooperate with an electronic engine control unit (ECU) (3). The managing system comprises:

a first module (4) structured to process electric signals from which the angular position of the engine driving shaft can be obtained;
a second module (5) structured to process electric signals from which the cycle phase of the engine (2) can be obtained;
a third module (6) structured to generate suitable signals for driving injector "drivers" (7) such that the injection profile stored inside the module is actuated; and
a fourth module (13) enabling the third module (6) and receiving signals from the first (4) and second (5) modules and from the third module itself (6).

Abstract: The invention concerns a robust communication system (1) for transmissions through a noisy environment, which comprises a cascade of a discrete signal source (2), a chaotic modulator (3) for the signal, a noisy transmission channel (4), and an incoherent discriminator or receiver (5). Advantageously in a preferred embodiment, the incoherent discriminator (5) comprises a high-pass filter (6) effective to remove the lowest frequency harmonics of the received signal, a rectifier (7) providing the absolute value of the wave, a low-pass filter (8) carrying out a mean of the rectified wave, and a comparator (9) placed after the low-pass filter.
