When the present difference value is greater than the threshold, executing a procedure for refreshing background noise to refresh the current reference measured values. The sensing points are defined by intersected electrodes, configured to form an array, and correspond to the current reference measured values. The reference points are located at the periphery of the array."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Capacitive sensing device and method that reduces influence from transient environmental changes","description":"A capacitive sensing method includes detecting present measured values of plural reference points from plural sensing points; generating a present difference value according to the present measured va","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9626054","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.
