The comparing and determining module receives the vehicle noise processing data and stores the voltage value of the vehicle noise processing data in a sequence according to time of occurrence for the comparing and determining module to compare and determine whether the rear car is approaching the vehicle, and output an alarming information, where the alarming module electrically connects to the comparing and determining module and sends out an alarming signal after receiving the alarming information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicle security alarming system determining relative velocity between a front car and a rear car by sounds retrieved therefrom","description":"A vehicle security alarming device determining a relative velocity between a front car and a rear car by sounds retrieved therefrom, comprising a vehicle noise processing module, which is configured t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9616814","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.
