  "title": "Nikola Tesla's Early System for Electric Lighting",
  "original_title": "System Of Electric Llghting",
  "summary": "A 19th-century patent by Nikola Tesla describing an early method for distributing and regulating electric light using high-frequency alternating current.",
  "what_it_does": "This patent details a system for powering electric lamps using high-frequency alternating current (AC). It focuses on the conversion of electrical energy into light through the use of an induction coil or transformer to step up voltage. The system is designed to maintain steady illumination by managing the frequency and intensity of the current delivered to the lighting elements, which were early predecessors to modern gas-discharge or vacuum-based lamps.",
  "what_it_does_not_cover": [
    "Does not cover modern LED or semiconductor-based lighting technologies.",
    "Does not cover low-frequency power distribution systems used in standard household wiring.",
    "Does not cover digital control systems or smart home lighting automation."
