An event based neuromorphic SPAD array microchip is also described. The chip architecture and triggering methodology takes a local group of SPAD sensors connected in a certain way and by using simple digital circuits emulating how neurons behave, patterns within a local receptive field are identified. Only when these unique patterns or features are identified are “events” triggered for each receptive field in the order they occur, or in an asynchronous manner. Each neuromorphic circuit (or collection of silicon neurons) act over overlapping receptive fields, and are tiled across the entire visual spatial field of the SPAD array to a form a convolution layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Neuromorphic single photon avalanche detector (SPAD) array microchip","description":"Described is a Single-Photon Avalanche Diode (SPAD) array microchip comprising: a plurality of SPAD sensors; and a triggering circuit configured to detect and read out the triggering order of SPAD sen","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11474215","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.
