    • A spheroidal ball comprising a plurality of segments arrayed substantially parallel to one another, each segment being adjacent to at least one other segment and to no more than two other segments, adjacent segments being adjoined to one another at substantially planar interfaces, the plurality of segments including a first segment having a first thickness and a first optical modulation characteristic, a second segment having a second thickness and a second optical modulation characteristic, and a third segment having a thickness different from at least one of the first and second thicknesses and an optical modulation characteristic different from at least one of the first and second optical modulation characteristics, the ball having an anisotropy for providing an electrical dipole moment, the electrical dipole moment rendering the ball electrically responsive such that when the ball is rotatably disposed in a nonoscillating electric field while the electrical dipole moment of the ball is provided, the ball tends to rotate to an orientation in which the electrical dipole moment aligns with the field.
    • 一种球形球,包括基本上彼此平行排列的多个段,每个段与至少一个其它段相邻,并且不超过两个其它段,相邻段在基本上平面的界面处彼此邻接,所述多个段 包括具有第一厚度和第一光学调制特性的第一段,具有第二厚度和第二光学调制特性的第二段,以及具有不同于第一和第二厚度中的至少一个的厚度的第三段和光学 调制特性不同于第一和第二光学调制特性中的至少一个,球具有用于提供电偶极矩的各向异性,电偶极矩使电子电响应,使得当球可旋转地设置在非振荡电场 而电偶极矩则为平衡 l,球倾向于旋转到电偶极矩与场对准的取向。
