The present technology can be applied to, for example, a ranging system or the like that detects a distance to a subject in a depth direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light receiving element and ranging system","description":"The present technology relates to a light receiving element and a ranging system capable of improving a pixel characteristic by responding to a change in a breakdown voltage due to a temperature chang","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11947049","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.
