Paragraph Number

122

In certain embodiments, the measurement circuit 330 may use feedback from a first sensor 510 to determine a reference axis. For example, a first sensor 510 such as an accelerometer or gyroscope or other electronic, magnetic, and/or electromechanical sensor may determine a horizontal plane relative to an orientation of the surgical device 200. Based on the horizontal plane, the measurement circuit 330 may determine that the reference axis is perpendicular to the horizontal plane. The measurement circuit 330 may determine a horizontal plane determine the reference axis relative to the horizontal plane. For example, the horizontal plane may be a plane parallel to the ground or surface of an operating table and the reference axis may be perpendicular to the horizontal plane.
