Title: Innovations by Henricus E Beekman
Introduction
Henricus E Beekman is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of electromagnetic devices, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is for an electromagnetic support with current-independent characteristics. This device is designed for positioning a body using at least two electromagnets. A position sensor measures the size of an air gap between one of the electromagnets and a guide beam. The output signal from the position sensor is processed by a linear electronic control unit, which adjusts the control current through the electromagnets based on the measured air gap. This design minimizes electrical resistance losses, making it particularly suitable for use in optical lithographical devices and other precision machinery.
Another significant patent involves an optical lithographic device that features a machine frame with a lens system. This device includes a positioning device that allows an object table to be displaced relative to the lens system. A force actuator system is integrated to counteract reaction forces, ensuring stability and precision during operation. This technology is essential for illuminating semiconductor substrates, where patterns are imaged onto the substrate using the lens system.
