Title: Innovations of Jean Guerard
Introduction
Jean Guerard is a notable inventor based in Juvisy, France. He has made significant contributions to the field of electrical engineering, holding a total of six patents. His work primarily focuses on the development of advanced electrical detection systems.
Latest Patents
One of his latest patents is an electric field detector. This device includes an electromechanical oscillator, which incorporates a piezoelectric element. A frequency measuring device is coupled to the oscillator to measure the oscillation frequency. Additionally, an electrical masking assembly is positioned close to the piezoelectric element, allowing it to vibrate relative to the assembly during use. This design exposes a variable part of the piezoelectric element to the electrical field being measured, resulting in a change in the oscillating frequency that indicates the electrical field measurement.
Another significant patent is a system and method for providing the amplitude and phase delay of a sinusoidal signal. This invention collects phase values of a reference signal, which indicate when the signal to be measured exceeds or falls below the reference. These phase values are transmitted to a computation unit, which determines the amplitude and delay values. The system can be implemented cost-effectively using an ASIC circuit or an FPGA circuit.
