Abstract

Cette invention concerne une balle sphérique comprenant plusieurs segments qui sont disposés d'une manière sensiblement parallèle l'un par rapport à l'autre, chaque segment étant adjacent à au moins un autre segment, mais pas à plus de deux autres segments. Les segments adjacents sont joints les uns aux autres au niveau d'interfaces sensiblement planes, l'ensemble des segments se composant des éléments suivants: un premier segment possédant une première épaisseur ainsi qu'une première caractéristique de modulation optique; un second segment possédant une deuxième épaisseur ainsi qu'une deuxième caractéristique de modulation optique; et enfin, un troisième segment possédant une épaisseur différente de l'une au moins des première et deuxième épaisseurs, ainsi qu'une caractéristique de modulation optique différente de l'une au moins des première et deuxième caractéristiques. Cette balle possède une anisotropie permettant d'obtenir un moment dipôle électrique, lequel moment rend la balle sensible à l'électricité. Ainsi, lorsqu'elle est mise en rotation dans un champ électrique non oscillant pendant que le moment dipôle électrique se produit, la balle va avoir tendance à tourner selon une orientation faisant s'aligner ledit moment dipôle électrique sur le champ.
