Abstract: A king pile for a combined wall system includes a first flange, a second flange, and a web. The first flange has a first flange body that is a generally rectangular plate having a first edge, a second edge, and a face. A first king pile interlock is formed integrally with the first flange body at the first edge, and a second king pile interlock is formed integrally with the first flange body at the second edge. The king pile includes a second flange having a second flange body, the second flange body being a generally rectangular plate having a face. The king pile also includes a web. The web may be a generally rectangular plate that is coupled to the face of the first flange body and the face of the second flange body. The first flange, second flange, and web may be formed separately and coupled by welding.

Abstract: A headgear system with first and second helmets is provided. The first helmet has a frontal bone section that covers a frontal bone of a wearer of the first helmet, and a first magnet component that is located at the frontal bone section of the first helmet. The first magnet component extends at least 90 degrees around the central axis of the first helmet. The second helmet has a frontal bone section that covers a frontal bone of the wearer, and a second magnet component is located at the frontal bone section of the second helmet. The magnet forces of the first and second magnet components repel one another when the first and second magnet components are located proximate to one another to help reduce force onto the head from impact.
