Title: Hannu Kulju: Innovator in Object Detection Technology

Introduction

Hannu Kulju is a notable inventor based in Hyvinkaa, Finland. He has made significant contributions to the field of object detection technology, holding three patents that showcase his innovative approach to monitoring and counting objects in various environments.

Latest Patents

One of his latest patents is a "Procedure and apparatus for detecting objects moving at varying speeds." This invention relates to a method for detecting and counting objects with varying velocities within a specific area. The system utilizes at least one passive detector to sense background radiation, amplifying the signal to produce a second signal that is independent of the object's distance and size. The frequency content of this second signal is analyzed to track the movements of the objects. The invention aims to create a cost-effective and straightforward detector by dividing changes in background radiation caused by each object into a series of flashes that hit a surface capable of detecting this radiation. This results in an electrical signal whose frequency is characteristic of each object's velocity and changes proportionally with variations in speed.

Another significant patent is the "Method for selecting the mode of operation of an object counting means." This method is designed for counting objects in a designated area, such as individuals waiting in an elevator lobby. The movements of the objects are monitored using at least one Doppler radar, which observes the Doppler frequencies of the signals reflected by the objects. The method allows for switching between two operational modes: one that focuses on counting objects based on their stopping and starting, and another that observes the movements of the objects over different time intervals.
