The present invention further also relates to a corresponding displacement sensor. The invention describes an operating principle of a sensor which is based on the Hall effect and which achieves an increase in the sensor output range with a magnet which is simultaneously reduced in size by storing the earlier value when control by the magnetic field is lost. In particular, the method comprises the steps of: calculating the position signal on the basis of a quotient of two magnetic flux density components; calculating a magnitude of the magnetic flux density and comparing the magnitude with a predetermined threshold value; outputting the current calculated position signal if the magnitude of the magnetic flux density is higher than the threshold value; outputting a preceding stored position signal if the magnitude of the magnetic flux density is smaller than or equal to the threshold value; storing the output position signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for contactlessly measuring a relative position by means of a 3D hall sensor having measurement signal store","description":"The present invention relates to a method for contactlessly measuring a relative position of a magnetic field source (102) which produces a magnetic field and a magnetic field sensor (100) in relation","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9618318","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
