Then, if it is determined that the inertial sensor is in the motionless state, the calibration apparatus decides a bias value of the inertial sensor based on the plurality of angular velocity values and corrects the obtained angular velocity value based on the bias value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Calibration apparatus and calibration method","description":"A calibration apparatus of an inertial sensor, obtains an angular velocity value from the inertial sensor, derives a distribution of a difference between temporally adjacent angular velocity values co","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11486894","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.
