  • Apparatus and method for orienting rotatable objects
    Publication number: 20060225582
    Abstract: An apparatus for orienting an object about its stable spinning axis includes a support having a support surface, the support surface being inclined relative to the horizontal. In this apparatus, the length and the inclination of the support surface is selected to, in combination, impart a minimum critical rotational velocity to an object rolled on the support surface. The minimum critical rotational velocity is sufficient to at least substantially align the rotation of the object about its stable spinning axis.
