Title: Innovations of Christophe Droit

Introduction

Christophe Droit is a notable inventor based in Besançon, France. He has made significant contributions to the field of sensor technology, holding three patents that showcase his innovative approach to remote interrogation systems.

Latest Patents

One of his latest patents is a system for interrogating a remotely interrogatable passive sensor integrated into a metal cavity with reduced system loss and interrogation method. This system includes a cavity that reflects RF waves and features at least one acoustic wave sensor with a resonance frequency band, coupled to a sensor antenna. The interrogation/reception device comprises means for transmitting and receiving RF signals within the interrogation frequency band, which includes the resonance frequency band of the sensor. It also includes a first and second transmission/reception antenna positioned within the cavity, along with means for dividing the signal into at least two RF signals. The system allows for the creation of a phase shift between these signals and includes means for analyzing the power level of the received signal.

Another significant patent involves a method of interrogation for a differential sensor of acoustic type that has two resonances. This method enables the measurement of a physical parameter by determining the difference between the natural resonant frequencies of the two resonators. The analysis is based on the cross-correlation of a signal representative of the level according to a splitting into two distinct frequency sub-bands. This method can be implemented in a radio-modem, providing a practical advantage in sensor technology.
