Next, the 3D sensor emits an infrared light in every interval times, and the infrared light will be reflected by static space each time. The reflected feedback signals are recorded and are sequentially compared to the first signal. When the feedback signal is equal to the first signal, the 3D sensor continues to operate, and when a human body enters the static space, causing the feedback signal to be different from the first signal, the 3D sensor identifies the human body to get an identified information, and comparing the identified information with an authentication database saved the 3D sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Operation method of smart warning device for security","description":"A three-dimension (3D) sensor disposed in a static space, the 3D sensor emits a first infrared light when initially turned on, the first infrared light is reflected by the static space, and then recei","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10475309","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.
