Analog Devices has 2 landmark patents explained in plain English on PatentBrief.

- [Improving MEMS Sensor Accuracy with a Co-located Reference Structure](https://patentbrief.org/patent/us/8939029/mems-sensor-with-movable-z-axis-sensing-element-8939029) — granted 2015
  This patent describes a tiny sensor (MEMS) that measures motion, especially up-and-down (z-axis), by including a special stable reference part electrically connected to the moving part, which helps cancel out environmental noise and makes measurements much more accurate.
- [How a MEMS Sensor Uses a Reference to Improve Z-Axis Accuracy](https://patentbrief.org/patent/us/8146425/mems-sensor-with-movable-z-axis-sensing-element) — granted 2012
  This patent describes a tiny sensor that measures up-and-down motion more accurately by including a special surrounding structure that helps cancel out environmental interference.
