    摘要: A position sensing and motion verification assembly for a motor-driven mechanism includes a base member on which a sensor pattern is fabricated. The sensor pattern includes a predetermined orientation of tabs and notches of varying widths. A home position is defined in the sensor pattern and the polarity of the pattern is inverted on opposite sides of the home position. A single sensor such as an optical interrupter is mounted in the assembly in a position relative to the sensor pattern to sense the tabs and notches.
