The first clock signals are divided into a data section in which the data signals are transmitted and received and an idle section in which the data signals are not transmitted and received. The first clock signals have a first frequency on the data section while having a second frequency on the idle section, and the second clock signals are clock signals maintaining a high value or a low value on the idle section."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"CRUM unit mountable in consumable unit of image forming apparatus and image forming apparatus using the same","description":"A customer replacement unit monitor (CRUM) unit that can be mounted in an image forming apparatus includes a decoder which receives first clock signals from the image forming apparatus and converts th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9658644","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.
