The mark consists of A semicircle design that includes the top half of a circular cog and a simplified line drawing of a house, drawn in relief in the bottom center. The cog includes three complete teeth across the top of the design and two half shown teeth on the lower right and left. In the gaps between the teeth are four bolts drawn as four circles with hexagons drawn in relief inside each of the circles. The cog also includes white accent lines on each of the teeth and in a semicircle around the house. The house itself is comprised of an isosceles triangle, drawn in relief, representing the main structure of the house, an angled line above the isosceles triangle, also drawn in relief, representing the roof of the house, and six rectangular blocks inside the isosceles triangle representing windows. The entire semicircle design is enclosed in a solid border line.
