US Patent 10238180 Position sensing assembly for a tensioning system

A position sensing assembly for a tensioning system designed to provide tension to a lace, cord, or other type of strand is disclosed. The tensioning system includes a reel member configured to rotate about a central axis and the position sensing assembly. The position sensing assembly includes a shaft, an indicator tab, and an optical sensing unit. The position sensing assembly assists in controlling the degree to which the strand is tightened and loosened. The position sensing assembly prevents tightening of the strand when the strand is meant to be loosened.
