When a user of the portable computing device senses danger or an emergency, the user communicates with an arbitrary tower from the plurality of communication towers. The arbitrary tower receives a notification from the portable computing device which triggers the arbitrary tower to scan a radius of influence of the arbitrary tower. After scanning the radius of influence, the arbitrary tower saves a list of identification data for at least one unknown portable computing device. A list of location coordinates and a list of user data is saved along with the list of identification data. Therefore, the list of identification data can be later analyzed to recognize the user of the unknown portable computing device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for identifying a portable computing device within a predetermined radius","description":"A method for identifying an unknown portable computing device within a specified radius is completed through a portable computing device and a plurality of communication towers that wirelessly communi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9801021","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.
