Latest Patents

Nangai holds a patent for an optical profile measuring method. This method involves determining the profile of the upper surface of the material being processed in a blast furnace by pulsing a laser beam at the surface. The angle of the emitter is incrementally changed along a predetermined path, while reflections of the beam are sensed using a detector positioned a fixed distance from the emitter. The profile points are calculated through triangulation, utilizing the emitting and detection angles along with the known distance between the emitter and detector. The method also includes ways to simplify calculations by making first approximation assumptions.
