The mark consists of a circle enclosing the following three sets of design elements: (1) four triangles, approximately equally spaced apart from one another, each with one side along the circle's edge and extending along the circle's radius toward the circle's center; (2) four instances of a geometric shape consisting of a curve joining two lines that converge to a point, where the instances of this geometric shape are approximately equally spaced apart from one another and each instance is approximately midway between one pair of the triangles already described; and (3) eight trapezoids, with one trapezoid between each triangle and each neighboring instance of the other geometric shape already described.
