Title: The Innovations of Bernard Perrier

Introduction

Bernard Perrier is a notable inventor based in Clermont-Ferrand, France. He has made significant contributions to the field of engineering, particularly in the development of innovative devices related to vehicle technology. With a total of 3 patents to his name, Perrier's work showcases his expertise and creativity in addressing complex engineering challenges.

Latest Patents

One of Perrier's latest patents is a tachometer for tires. This device counts the rotations of a tire on a vehicle by utilizing the deformations that the tire undergoes with each rotation. It comprises a casing and a sensor that generates an electrical signal for each wheel rotation. The sensor is designed as a passive component integrated with the casing, producing signals proportional to the variations in magnetic flux. A magnetic field generator is positioned opposite the passive sensor, and the connection means link the casing and sensor to the tire's surface. The electrical signal is generated through the relative movements of the passive sensor and the magnetic field generator.

Another significant invention by Perrier is a hydrostatic-pressure-sensitive actuator. This actuator is designed for use in pressurized enclosures and creates relative movement between two parts in response to changes in hydrostatic pressure. It features a closed-cell foam block that is fixed to both parts, allowing for its application in deploying wheel units and antennas within the cavity formed by a tire and wheel rim.
