The electromagnetic clutch is also connected to a spring motor which dynamically connects to the speed reducer. In the deploying and retracing direction of the LCD, a stowed position transducer and a retracted position transducer are disposed to monitor the LCD position changes and an angle sensor to monitor the LCD deploying speed changes. The stowed position transducer, retracted position transducer, and angle sensor are electrically connected to a controller. The controller collects and processes signals generated by the stowed position transducer, retracted position transducer, and angle sensor and controls LCD retracting in the event of power outage or unexpected exceptions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device for deploying and retracting liquid crystal display (LCD) and control method thereof","description":"The servomechanism comprises a gear motor, a one-way bearing dynamically connected to the gear motor, an electromagnetic clutch, a speed reducer, and a plane four-bar linkage mechanism which drives th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9832416","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.
