  "title": "Weapon That Shoots Wires to Deliver Electric Shocks",
  "original_title": "Weapon for immobilization and capture",
  "summary": "This 1974 patent describes a weapon that fires projectiles carrying wires to deliver incapacitating electric shocks to a target from a distance.",
  "what_it_does": "This patent details a weapon system designed to subdue targets using electricity. It involves a launcher that fires projectiles, like pellets or nets, connected by thin, conductive wires to a power source. When the projectile hits a target, the wires establish an electrical path. The weapon then delivers a high-voltage, low-capacitance electrical discharge in brief pulses. This shock is intended to immobilize the target. The patent specifies delivering over 0.001 joules at voltages greater than 20 KV, with a specific capacitance-voltage product (CV) limit to ensure energy transfer. Some embodiments include a net assembly to entangle the target and ensure good contact.",
  "what_it_does_not_cover": [
    "Weapons that deliver continuous electrical current instead of discrete impulses.",
    "Electrical discharges with a capacitance-voltage product (CV) higher than 10^2 volt-farads.",
    "Electrical impulses delivered at voltages below 20 KV.",
    "Weapons that require direct physical contact for electrical delivery, without projectiles.",
    "Systems that deliver less than 0.001 joules of energy."

  "abstract": "A weapon for subduing and restraining includes a harmless projectile that is connected by means of a relatively fine, conductive wire to a launcher which contains an electrical power supply. The projectile is intended to contact a living target without serious trauma and to deliver an electric charge thereto sufficient to immobilize. In different embodiments, the projectile can be a pellet, a net or a combination of pellets and a net. The magnitude and frequency of the electrical impulses delivered to the target can be controlled at the launcher, and would range in effect from immobilizing to potentially ''''lethal'''' levels.",
