A processing block provides a starting value of the roll estimation, used to decrease an initial roll estimation error, by storing past values of the acceleration signal, during a time interval preceding start-up; and, upon start-up, retrieving and processing the stored past values to generate processed acceleration data, used by the sensor fusion processing stage to initialize the sensor fusion algorithm and generate the starting value of the roll estimation quantity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pointing electronic device with fast start-up recovery and corresponding method","description":"In an embodiment pointing electronic device, a sensor fusion processing stage generates an orientation estimation quantity indicative of an orientation about a longitudinal axis based on a sensor fusi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11249562","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.
