A second sensor is a beta gauge or infrared sensor for providing a second sensor signal that includes data for determining a total weight per unit area of the coated substrate or of the sheet material A computing device receives the measured x-ray signal value and the second sensor signal configured to implement an x-ray based calculation that utilizes absorption coefficients for the coating material and sheet material, the measured x-ray signal value, the x-ray spectrum, and the weight measure as a calculation constraint, for computing at least the weight per unit area of the coating material."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"X-ray-based determining of weights for coated substrates","description":"A measurement apparatus includes an x-ray sensor including an x-ray source having a high voltage power supply for emitting an x-ray spectrum and an x-ray detector for providing a measured x-ray signal","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11519867","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.
