Title: Guy Ravalitera: Innovator in Thermal Measurement Technologies

Introduction

Guy Ravalitera is a notable inventor based in Bethune, France. He has made significant contributions to the field of thermal measurement technologies, holding a total of 2 patents. His work focuses on innovative devices that enhance the accuracy and efficiency of temperature gradient measurements.

Latest Patents

Ravalitera's latest patents include a thermocouple array for a thermal fluxmeter. This invention features a thermal fluxmeter with multiple thermocouples, which consist of a continuous thin layer of a first conductor or semiconductor material, such as constantan. This layer is covered on at least one face by a series of very thin deposits of a second conductor or semiconductor material, like copper, which has a different thermoelectric power. A key characteristic of this invention is the presence of channels that traverse through each deposit area and the underlying thin layer, allowing for enhanced thermal sensitivity.

Another significant patent is a device sensitive to temperature gradients and heat flow. This device comprises at least one elementary cell formed by a thin layer made from a first electric conductor or semiconductor, such as constantan, coated with a very thin electrolytic layer of a second electric conductor or semiconductor, such as copper. The invention has demonstrated that induced electric currents flow through the surface separating the conductors, with electric voltages being proportional to the instantaneous spatial mean of the surface thermal gradient. This technology has applications in measuring temperature gradients, heat flows, and converting heat energy into electric energy.
