Abstract
An article of footwear, method, and motorized lacing system includes a motor, including a motor shaft, a spool, coupled to the motor shaft, configured to spool and unspool the lace based on the turning of the motor shaft, a processor circuit, and a three-dimensional encoder. The three-dimensional encoder defines a major axis and has a surface having a tabs extending from a drum, an optical sensor, positioned within optical range of the cylindrical encoder, configured to output a signal to the processor circuit indicative of a detected one of the tabs, and a beam break, positioned between the three-dimensional encoder and the optical sensor, forming a pair of slits. The optical sensor is positioned to view the tabs through the pair of slits, wherein the processor circuit is configured to operate the motor based, at least in part, on the signal as received from the optical sensor.
