The baseline value correction unit sets the time X for varying the baseline value and/or the upper limit value Y thereof for each electrode pair according to the capacitance of each electrode pair."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch panel device","description":"A touch panel device includes a capacitance type touch panel having a plurality of electrodes arranged in directions intersecting each other, a capacitance measurement unit that measures capacitance o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11977706","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.
