Each light valve assembly has a first state in which the person is able to see therethrough and an alternative second state in which viewing therethrough is prevented. A controller controls whether the light valve assembly is in the first state or the second state to thereby control viewing therethrough. The light valve assembly may be situated rearward of part of the viewing portion. Only the headpiece wearer is thus able to view test questions on a display through the light valve assembly."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Biometric identification headpiece system for test taking","description":"Headpiece for test-taking includes a frame having support structure for supporting the frame on a person's head and a viewing portion configured to be in front of the person's face when the frame is s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10540907","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.
