Title: The Innovations of Patrick Coquerel
Introduction
Patrick Coquerel is a notable inventor based in Sartrouville, France. He has made significant contributions to the field of signal processing, holding a total of 5 patents. His work focuses on methods and devices that enhance the transmission and restoration of clock signals.
Latest Patents
One of his latest patents is a method and device for restoring a clock signal. This invention aims to accurately detect the transition instants of signals transmitted over a channel by analyzing samples taken during a fraction of the clock period. The device determines deviations between the amplitudes of various samples and compares these with standard configurations to estimate the position of the sampling time window. If the window is not correctly centered, a local clock is phase-shifted to resynchronize it.
Another significant patent is a process and device for the digitized transmission of signals. This invention simplifies the transmission of analog signals from sensors to a remote station. It includes a local electronic module that oversamples each analog signal and converts it into lower resolution digital words. A synchronization element produces a clock signal for synchronization with the remote station, which includes a receiver and a digital filter to convert the received bit stream into higher resolution digital words. This invention is particularly useful for the transmission of seismic data.
