The inventive system employs a current measurement circuit, a microprocessor controller including a timing circuit and control algorithm code structure, a TRIAC current switch and an on-board battery. The inventive system and method is universal, being independent of the charger design, and may be an independent device upstream of the charger (between it and the mains power supply), integrated with an AC adapter charger unit, integrated into a CED, or part of a power strip for individually and independently controlling each AC adapter plugged into the strip."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Energy conserving charger controller, circuitry and method","description":"An energy-conserving charger controller system, including charge sensing circuitry and operational algorithm, reduces parasitic lost energy by automatically “learning” the unique charging signature of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8508079","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.
