The device further comprises a component for projecting the gravitational components and the linear acceleration components into an n-dimensional space, where and for performing a clustering process on the projections of gravitational components and linear acceleration components into n-dimensional space to produce clustering results. The clustering results comprise a plurality of clusters each of which represents a brushing area. A brushing area can be determined based on an assignment of subsequent gravitational components and linear acceleration components of acceleration data to a particular cluster, and feedback provided to a user based on the determination of brushing area, thereby providing indication of brushing activity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Toothbrush coaching system","description":"A device for providing an indication of brushing activity of a toothbrush comprises an accelerometer configured to produce acceleration data from motion of the toothbrush, and components for filtering","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11941997","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.
