In one example, key assemblies may be provided that each employ one or more electro-permanent magnets (EPMs) together with permanent magnet and/or magnetically permeable (e.g., ferromagnetic) key assembly components to control key retraction and extension, and/or to control peak depression force (e.g., typing force) required to depress and displace a key assembly from an extended position to a lower position that causes the key assembly to produce a digital or analog output signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for implementing retractable and/or variable depression force key assemblies","description":"Systems and methods are disclosed herein that may be implemented to configure, provide and operate retractable key assemblies and/or key assemblies that present a variable key assembly depression forc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10491214","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.
