Leonel Francisco Castañeda Heredia

Introduction

Leonel Francisco Castañeda Heredia is a distinguished inventor hailing from Medellín, Colombia. With two notable patents to his name, Leonel has significantly contributed to the field of railway technology through innovative inspection systems.

Latest Patents

His first patent, titled "System and method for inspecting the geometric parameters of the wheels of railway vehicles," addresses the challenge of automated inspection using advanced artificial vision techniques. This invention utilizes a structured light source that illuminates a line on the surface of railway wheels. A CCD camera captures images of the illuminated area, while a data processing system reconstructs information about the wheel's transverse section, allowing for precise geometric parameter calculations.

Leonel's second patent, "System for detecting defects in the roundness of railway vehicle wheels," provides a device designed to evaluate the tread condition of moving railway vehicles. This system employs a measurement point that generates a signal proportional to rail deformation as a wheel passes over it. The comparator then assesses the measured signal against a standard wheel without roundness defects. This innovation facilitates efficient monitoring of wheel integrity and transmission of defect data over a network.
