The machine-readable indication of exceedance being represented by a machine-readable difference between the at least one variable visually-sensible characteristic and the at least one selectable visually-sensible characteristic, the barcoded quality indicator providing a first machine-readable indication prior to the exceedance of the at least one threshold and a second machine-readable indication, different from the first machine-readable indication."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for quality management utilizing barcode indicators","description":"A barcoded quality indicator operative to provide a machine-readable indication of exceedance of at least one product quality threshold by at least one product quality affecting parameter, the barcode","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8540156","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.
