The disc member has a multiplicity of shape-shifting arc segments that can respond to electromagnetic fields acting on them. Each shape-shifting arc segment passes a shape-shifting region of the apparatus at a frequency of rotation of the encoded motor multiplied by the number of such arc segment. ## Claims ### Claim 1 An apparatus comprising a cylindrical shaft member coupled to a motor with a motor frame;
