    Patent number: 6618234
    Abstract: Damage to electronic golf course sprinkler valve controls from lightning current surges is prevented by electrically isolating the actual valve control circuit from the logic circuitry that controls it, using in the valve control circuit only components and printed traces that can withstand at least as much power dissipation as the field wiring, and grounding each valve control individually to earth ground through a plasma discharge device.
