Title: Innovations of Ulrich Lachmann
Introduction
Ulrich Lachmann is a prominent inventor based in Munich, Germany. He has made significant contributions to the field of technology, particularly in the development of advanced sensor systems. With a total of eight patents to his name, Lachmann's work showcases his expertise and innovative spirit.
Latest Patents
One of his latest patents is a rotation detector using differential Hall sensor circuitry. This invention provides a high-resolution and precise rotation detection for a magnet wheel while requiring only the space of a single differential Hall integrated circuit (IC). The electronic component combines the circuitry equivalent to at least two differential Hall ICs and derives a digital signal sequence with a frequency twice that of a signal from a single differential Hall circuit. This is achieved by coupling the output signals of the differential Hall circuits, utilizing only three Hall sensors to form the necessary difference signals.
Another notable patent is a circuit configuration having a pair of multi-Hall generator Hall sensors. This configuration allows for contactless detection of the RPM of a rotating gear wheel. It includes two identical Hall sensors that are firmly mounted and magnetically prestressed, spaced apart by a distance equal to one-half the tooth pitch of the gear wheel. Each Hall sensor features at least one pair of identical Hall generators, with voltage/current converters coupled to their signal paths. An evaluation circuit links the outputs of these converters in phase opposition, enhancing the detection capabilities.
