The transmission and compensation electrodes can be supplied with electric switching signals of predetermined frequency and amplitude. The electric switching signal at the compensation electrode is phase-delayed with respect to the electric signal at the transmission electrode. Alternating electric fields radiated at the transmission and compensation electrodes generate in the reception electrode a current that is representative of an approach of a hand to the hand-held device. The transmission and reception electrodes are arranged such that the impedance between the transmission and the reception electrodes exceeds a predetermined value suitable to keep the current generated in the reception electrode under a predetermined value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electrode system for proximity detection and hand-held device with electrode system","description":"An electrical hand-held device with proximity detection can be placed on a surface and has at least one transmission electrode, at least one reception electrode, and at least one compensation electrod","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8493074","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.
