  • Fuse clip for circuit boards
    Patent number: 6702595
    Abstract: A stable fuse clip for printed circuit boards has a vertical back plate, a pair of forwardly extending vertical flanges, and a rearwardly extending horizontal flange strengthened against bending. The horizontal flange, the bottom edges of the vertical flanges, and the bottom edge of the back plate are horizontally coplanar and rest on the surface of the circuit board. Two legs extend downwardly through the board from the lateral sides of the back plate, and one leg extends downwardly from the distal end of the horizontal flange.

  • Lightning protection for irrigation controls
    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.
