In an illustrative example, the DLSRD may determine an angle between a lanyard coupled to the user and a vertical plane between the two receivers. The DLSRD may include, for example, an extraction detector detecting an extracted length of the lanyard. The DLSRD may determine user proximity to a safe operating area boundary based upon a difference of a current extracted length of the lanyard to a learned extracted length associated with a current angle of the lanyard, for example. Various DLSRDs may be configured in a run-mode to apply a braking effect to the lanyard and/or to activate a warning device based upon the user's proximity to the boundary."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distance-learning safety retraction lanyard","description":"Apparatus and associated methods relate to a distance-learning safety retraction device (DLSRD) mechanically coupled to a fixed anchor point on a boundary-mapped surface, the DLSRD including two recei","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10512801","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.
