An output signal generator responsive to the comparator output signal is configured to generate a sensor output signal indicative of a one or more conditions of motion of the object including: an absence of normal rotation, a direction change, and a vibration. In some embodiments, the vector angle comparator may generate a comparator output signal indicative of a comparison of a vector angle value and one or more threshold values. In this case, the output signal generator may be configured to generate a sensor output signal indicative of a speed of motion and/or a position of the object."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Magnetic field motion sensor and related techniques","description":"A magnetic field sensor for detecting motion of an object includes magnetic field sensing elements to generate at least two phase-separated magnetic field signals and a processor including a vector an","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9739637","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.
