Claim 0:
1. A motorized system, comprising:
a motor, including a motor shaft;
a processor circuit;
an optical encoder, comprising:
a 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
an optical sensor, positioned within optical range of the three-dimensional encoder, 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
a printed circuit board on which the processor circuit and the optical sensor are positioned, 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.
