Title: Innovations of Lionel Rosellini

Introduction

Lionel Rosellini is a notable inventor based in Paris, France. He has made significant contributions to the field of gyroscopic systems, holding a total of 3 patents. His work focuses on enhancing the functionality and accuracy of gyroscopic devices.

Latest Patents

One of his latest patents is related to the calibration of a vibrating gyroscope. In this invention, a vibrating gyroscope is controlled in gyrometer mode within a control loop. The control loop corresponds to at least one current control for an operating parameter. A modified control is applied to the gyrometer for the operating parameter by introducing a sinusoidal interference into the current control. This modified control is then utilized to determine a resulting measurement value. Based on this measurement value, a decision is made on whether to repeat the previous steps based on the last determined sinusoidal interference.

Another significant patent involves a method for updating a value of orientation with respect to north in an apparatus that includes an image sensor. This method is particularly useful in systems like binoculars that are coupled with a geographical north seeker incorporating a gyrometer. The invention determines the shift of two images from the digital image sensor at distinct instants to construct information representative of angular movement. This information is then used to update the orientation value of the image sensor and to differentiate between movements due to ground shifts and those caused by the Earth's rotation.
