Paragraph Number

129

In the illustrated embodiment, the surgical device 200c differs from the surgical device 200a or surgical device 200b because the surgical device 200c includes at least one surface of the housing 220 that is planar. In certain embodiments, one or more sensors (e.g., first sensor 510 and/or sensor 530) may be used by the electronic circuit 300/400 to determine a reference axis 130 and/or a horizontal plane from which a reference axis 130 can be determined. Alternatively, or in addition, the electronic circuit 300/400 can determine a reference axis 130 by retrieving data from memory media 560 that defines the reference axis 130.
