If the validity time information includes a standard time that represents a current time, the standard time together with a relative time or period information in the validity time information is used for determining whether a valid period has passed. If the validity time information does not include the standard time representing the current time, the lapse of the valid period is determined based on the standard time generated by a standard time generator and one of the relative time and the period information in the validity time information. Then, the external information is invalidated by deleting the information from an information storage if it is determined that the valid period has passed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Information processing apparatus for movable body and vehicle navigation apparatus","description":"A navigation apparatus acquires, through an antenna and a receiver, external information such as traffic information or the like, and a control unit in the navigation apparatus acquires validity time ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8463539","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.
