Claim 5:
6. A method for making a motorized system, comprising:
positioning a processor circuit on a printed circuit board;
operatively coupling a motor to the processor circuit, the motor including a motor shaft;
positioning a three-dimensional encoder in relation to the motor, the three-dimensional encoder defining a major axis and having a surface having a first plurality of segments positioned between a second plurality of segments, the first plurality of segments having a different light reflecting characteristic than the second plurality of segments, the three-dimensional encoder secured to the motor shaft such that the turning of the motor shaft causes the three-dimensional encoder to rotate about the major axis, wherein the surface of the three-dimensional encoder faces the major axis; and
positioning an optical sensor on the printed circuit board and within optical range of the three-dimensional encoder, the optical sensor configured to output a signal to the processor circuit indicative of a detected one of the first and second plurality of segments;
wherein the processor circuit is configured to operate the motor based, at least in part, on the signal as received from the optical sensor; and
wherein the optical sensor comprises a first optical sensor on a first major surface of the printed circuit board and a second optical sensor on a second major surface of the printed circuit board on an opposite side of the first major surface.
