Accordingly, analog feedback is used for external integrated circuits (IC) controlled by a PWM output, for processes to be analyzed. The apparatus includes a microprocessor that integrates an autonomous PWM module and an analog-to-digital converter (ADC) group manager, each including register modules for enabling analog-to-digital signal conversion comparisons of PWM feedback data, and generating of an interrupt command when required, and more specifically to automatically initiate transfer of data from the ADC to memory responsive of an interrupt trigger. As may be necessary the output of the ADC is calibrated or otherwise scaled to enable proper operation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and methods thereof for reducing energy consumption for PWM controlled integrated circuits in vehicles","description":"An apparatus, protocol and methods for reducing vehicle energy consumption and for precise electronic event control, by implementing full CPU off-loading, using pulse-width modulation (PWM) with analo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8502721","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.
