The difference extraction device searches a search range by a search unit to find whether search target data of the control program is included in the common program, and generates the difference data. The search range includes, for example, an address of the search target data in the control program and addresses rearward of that address. An offset area is provided in a head area of the common program."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Program update method and update system","description":"An update system includes: a first server that stores a control program; a second server that stores a common program; a difference extraction device that generates difference data between the common ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11941388","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.
