Patent ID: 8668618

Claim:
A rotary unit, comprising: at least one rotational component comprising at least first and second gear components and at least one gear structure receiving area, wherein the first gear component substantially fixedly extends from a first surface of the rotational component, wherein the first gear component is configured to operably engage one or more other gear components of another rotary unit when the first gear component is disposed proximal to the other gear components, wherein the second gear component substantially fixedly extends from a second surface of the rotational component, wherein the second gear component communicates with the gear structure receiving area, wherein the gear structure receiving area is configured to receive one or more gear structures or components thereof, and wherein at least one surface of the rotational component comprises at least one implement; and, at least one gear structure comprising at least one support component and at least a third gear component rotatably coupled to the support component, wherein the third gear component is configured to operably engage one or more other gear components when the third gear component is disposed proximal to the other gear components, and wherein the rotational component is configured to rotate relative to the support component, which support component is substantially fixedly positioned when the rotational component rotates relative to the support component.
