  • Method for monitoring a machine on the basis of electric current signals and device for implementing such a method
    Patent number: 11885849
    Abstract: A method can be used for supervising the operation of a machine powered with electric current. The method includes operating the machine in a normal operation mode, repeatedly performing a learning phase for learning the normal operation machine of the machine to create a knowledge base, autonomously switching from the learning phase into a supervision phase when the knowledge base is considered to have been created, and repeatedly performing the supervision phase.
    Type: Grant

  • LEARNING METHOD FOR THE DETECTION OF ANOMALIES FROM MULTIVARIATE DATA SETS AND ASSOCIATED ANOMALY DETECTION METHOD
    Publication number: 20230126849
    Abstract: A method can be implemented on a microcontroller that includes at least one memory. The microcontroller is configured to receive sets of multivariable data from at least one sensor and the memory is configured to store a predefined number of categories. A category is associated with a mean and a covariance matrix. The method can be used to the detection of anomalies from the sets of multivariable data.

  • METHOD FOR MONITORING THE OPERATION OF A MACHINE GENERATING VIBRATIONS AND DEVICE FOR THE IMPLEMENTATION OF SUCH A METHOD
    Publication number: 20220011154
    Abstract: A method for monitoring the operation of a machine that generates vibrations, includes a learning phase in which a knowledge base containing vibrational signatures representative of the operation of the machine is generated, and a monitoring phase in which the vibrations of the machine are compared to the knowledge base so as to detect an anomaly in the machine.
