The instructions may cause the processor to: receive the touch input from the user, receive an impedance value based on the touch input measured by the impedance sensor, and determine whether the received impedance value corresponds to at least one stored impedance value associated with a user profile."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Access control authentication based on impedance measurements","description":"A computing device may be configured to authenticate a user for access control, and may include at least one ground electrode configured for contact with a user, an impedance sensor coupled to the lea","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9661499","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.
