Title: Innovations of Olivier R Marroux

Introduction

Olivier R Marroux is a notable inventor based in Biard, France. He has made significant contributions to the field of angle sensing technology, holding a total of 4 patents. His work focuses on innovative solutions that enhance the accuracy and functionality of angle sensors.

Latest Patents

One of his latest patents is the Out-of-round coder. This invention features an angle sensor designed to detect out-of-round conditions. It includes a disc that supports an angle coder, which is rigidly attached to a rotating shaft. The system employs at least one fixed optical system with a coherent light source that emits a beam to interfere with the angle coder, allowing for precise coding of its angular position. An alternative embodiment of this invention utilizes two optical systems arranged 90° from each other. Another embodiment includes a single optical system, where the disc has a circular track that is radially centered in at least one of its angular positions relative to the incident collimated light beam, along with a radially oriented photo detector.

Another significant patent is the Optical rotation counter. This device is associated with a rotary disc of an angle sensor and includes means for coding the angular position of the disc. It features a fixed source of coherent light that emits a light beam, a diaphragm, and a support that moves with the rotation of the coding disc. The support contains at least one cell for coding its displacement, generating an optical code through interference with the incident light beam. This optical code is then readable on at least one photodetector.
