Title: Innovations by Jacques Prado
Introduction
Jacques Prado is a notable inventor based in Egly, France. He has made significant contributions to the fields of signal processing and sleep state analysis. With a total of two patents to his name, his work reflects a deep understanding of complex systems and their applications.
Latest Patents
Jacques Prado's latest patents include a method and device for the analysis of a return signal and adaptive echo. This invention involves submitting a forward signal to a finite-impulse-response linear-prediction filter to determine a first residual signal of minimal energy. The return signal is then processed through a similar filter to ascertain a second residual signal. By calculating the ratio of energies in both residual signals, the invention can detect whether the return signal contains components beyond the echo from the forward signal.
Another significant patent by Prado is a method for determining a subject's sleep state through electroencephalographic signal processing. This method allows for real-time determination of sleep stages as EEG signals are collected. The EEG signal is divided into time segments, and various standardized correlation coefficients are calculated for each segment. The method assigns each segment to a class based on energy distribution across frequency bands, facilitating accurate sleep state analysis.
