Latest Patents

Wulf Reise's latest patents showcase his expertise in enhancing user interaction with electronic devices. His first notable patent describes a push-button switch that combines both mechanical and capacitive functionalities. This invention employs a pressure-switching feature to recognize key actuation alongside a capacitive sensor function to identify key touches. The design incorporates an electrically conductive key and a printed circuit board containing electrical contacts activated by pressing the key through a switching mat. Furthermore, it includes a capacitive sensor surface that operates opposite and at a distance from the key, allowing for advanced touch recognition.

In addition, Reise's second patent outlines a method for determining the position of a touch on a capacitive sensor field composed of a grid of discrete electrodes. This method involves measuring capacitance values for each electrode and checking whether they exceed a predefined threshold. The approach enables the calculation of a rough touch position by weighing the electrode positions with their capacitance values. It further refines the touch position through the calculation of a touch diameter, utilizing a value table containing empirically determined correction values.
