In the described preferred embodiments, the second machine-sensible elements are magnetic elements; and the pulse generator includes a coil, a magnetic core magnetically coupled to the coil, and a spring-mounting for the magnetic core causing the core to move from an initial position in one direction with respect to the coil when aligned with one of the second machine-sensible elements, and to be returned in the opposite direction by the spring to its initial position, whereby the coil generates pulses during such movements of the magnetic core."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for measuring displacements of displaceable members","description":"Apparatus and method for measuring displacements of a rotary or linearly-displaceable member by counting periods of displacement thereof along a predetermined displacement path, including a pulse gene","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8461830","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.
