Title: Innovations by Inventor Nordh Ulf
Introduction
Nordh Ulf is a notable inventor based in Norrkoping, Sweden. He has made significant contributions to the field of microwave technology, holding 2 patents that showcase his innovative approach to heating apparatuses.
Latest Patents
One of his latest patents is a microwave heating apparatus. This invention discloses a method for heating a load using microwaves. The apparatus includes a transmission line that transmits microwaves from a generator to a cavity. It features a sensing device that measures electromagnetic field strengths, providing information about the phase and amplitude of a reflection coefficient. This coefficient represents the ratio between the microwaves reflected back towards the generator and those transmitted through the line. A control unit detects whether the measured electromagnetic field strengths correspond to a reflection coefficient within specific intervals of phases and amplitudes. This detection allows the control unit to manage the feeding of microwaves to the cavity effectively.
Another significant patent is a shielding system for microwave ovens. This system includes a first layer of parallel grounded conductors and a second layer of parallel grounded conductors that are substantially perpendicular to the first layer. For high frequency, these layers are electrically insulated from one another. Each layer consists of a plurality of parallel metal wires connected at one end and grounded, ensuring effective shielding for microwave ovens.
