Title: Martinus H Van Delden: Innovator in Magnetic Field Sensing Technology
Introduction
Martinus H Van Delden is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of magnetic field sensing technology, holding two patents that showcase his innovative approach to sensor design. His work is primarily associated with U.S. Philips Corporation, where he has developed advanced technologies that enhance sensor performance.
Latest Patents
One of Van Delden's latest patents is a magnetic field sensor featuring a double Wheatstone bridge. This sensor design incorporates a substrate with multiple resistive elements that form the bridge circuit. Notably, at least one resistive element in each bridge possesses a magneto-resistive characteristic. The two bridges are designed to be identical, with the output polarities of corresponding magneto-resistive elements being opposite. This configuration allows for the determination and elimination of the sensor's zero-point offset without the need for conventional techniques that increase power consumption.
Another significant patent involves a magnetic head constructed with a core portion of polycrystalline MnZn ferroferrite. This design exhibits a remarkably low 'rubbing noise' level when the average grain size of the material is between 0.2 and 3.0 micrometers. Specifically, the rubbing noise level can be lower than the electronic noise level when the grain size ranges from 0.5 to 2.0 micrometers. This advancement makes the magnetic heads particularly suitable for use in the frequency range of 5 to 100 MHz.
