Abstract: An architecture of an ignition and/or injection managing system for an internal combustion engine, of the type structured to cooperate with an electronic engine control unit. Also included is an electronic device architecture for determining the operating phase of an internal combustion motor, of the type structured for cooperating with an electronic motor control unit and inputting a signal issued from a sensor of a phonic wheel associated with the motor camshaft. This device has the task of computing the operating phase by analyzing the signal from the sensor of the driving shaft phonic wheel, so as to release the electronic motor control unit from monitoring the phonic wheel signal, in order to lighten its computational load, and to enable the processing of the signal issuing from a variety of the phonic wheels more commonly used in the automotive industry. The device has the task of calculating the angular position of the driving shaft by analyzing the signal transmitted by the tone wheel of the driving shaft, thereby releasing the engine electronic control unit from the monitoring of the driving shaft angular position to reduce its computational load and allow to process the signal transmitted by a plurality of tone wheels highly widespread in the automotive field. A module is provided that is capable of emitting an interrupt signal toward said control unit on the basis of signals received by said second module.

Abstract: A method to protect the contents of an electronic document through an encryption system based on an initial confusing step in a scrambler and a subsequent diffusion step in a chaotic processor, both steps being of a chaotic type. Initially, encryption keys and an initial chaotic value are acquired; input character strings are acquired; and diffused character strings are calculated using the input character strings, the encryption keys, and previous diffused character strings. After a certain number of iterations, sets of diffused character strings are added to subsequent chaotic values generated by a chaotic processor to obtain encrypted words. Decryption is obtained through two successive operations, wherein the encrypted words are added to chaotic values identical to the encryption values and subtracted from previously decrypted words using an unscrambler element having a structure similar to that of the scrambler and using identical encryption keys.

Abstract: A circuit implementing a non-integer order dynamic system includes a neural network that receives at least one input signal and generates therefrom at least one output signal. The input and output signals are related to each by a non-integer order integro-differential relationship through the coefficients of the neural network. A plurality of such circuits, implementing respective non-integer order controllers can be interconnected in an arrangement wherein any of the integral or differential blocks included in one of these circuits generates a signal which is fed to any of the integral or differential blocks of another circuit in the system.
