The sample match state can be, for example, one of a positive match state, a mixture match state, a negative match state, and a match error state. In some embodiments, the error state can be at least one of a background error state, a user error state, and an instrument error state, or any combination thereof."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Visual indicator of scan workflow","description":"A hand-held spectrometer includes at least one indicator light and a processor configured to control the at least one indicator light to indicate a state of the hand-held spectrometer selected from a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9841321","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.
