Title: Ivon Franciscus Helwegen: Innovator in Photo Acoustic Detection and Accelerometer Technology.

Introduction

Ivon Franciscus Helwegen is a notable inventor based in Herten, Netherlands. He has made significant contributions to the fields of photo acoustic detection and accelerometer technology. With a total of 6 patents to his name, Helwegen continues to push the boundaries of innovation.

Latest Patents

One of his latest inventions is a photo acoustic detector with improved signal processing. This device is designed to detect the concentration of a sample in a mixture by utilizing a light source to produce a light beam that excites the molecules of the sample. The light modulator generates pressure variations in the sample mixture, and the amplitude of these variations serves as a measure of concentration. The detector includes a detector element that converts pressure variations into a detector current, which is then processed to generate an output signal representing the concentration. The processing section features an integrating amplifier coupled to the detector element via a hold switch, along with a timing circuit that generates a hold signal for optimal operation.

Another significant invention is a two-dimensional adaptive accelerometer based on dielectrophoresis. Unlike conventional accelerometers that rely on test masses suspended in a spring damper system, this innovative design measures the acceleration of a freely floating test mass in a medium. The movement of the test mass is determined by the accelerating force acting upon it, and a non-uniform electric force field allows for a wide and adjustable dynamic range.
