  • Electronic system for monitoring the state of awareness of an operator in an aircraft, associated method and associated computer program
    Publication number: 20230343112
    Abstract: An electronic system for monitoring the state of awareness of an operator in a control station of an aircraft. The monitoring system includes a module for receiving a datum from at least two sensors onboard the aircraft, at least one of the sensors being called a worn sensor being in physical contact with the operator and at least one of the sensors being called an off-set sensor being at a distance from the operator, a processing module configured for extracting from each datum at least one parameter representative of the state of awareness of the operator, a fusion module configured for receiving the representative parameters and implementing a machine learning method for determining, depending on the representative parameters, whether the operator is in a nominal or an altered state of awareness.

  • Device and method for analyzing the state of a system in a noisy context
    Patent number: 11610073
    Abstract: A computer-implemented method for determining the state of a system, which includes steps of: collecting data relating to a system, the data being noisy data comprising data of interest and noise; generating a signal to be analyzed from the collected data, the signal being a noisy signal comprising a signal of interest and noise; analyzing the regularity of the signal of interest by compensating the influence of the noise in the computation of the power of the difference between the integrated noisy signal and its trend; and determining the state of the system depending on the result of the analysis of the regularity of the signal of interest.
