Abstract:
1. A system for digitally recording the motion of an instrument including: a power source; at least two partially hollow tubes made of electricially-conductive material coupled to said power source through first connection, said at least two partially hollow tubes including a viscous material in the interior contacting said electrically-conductive material in a first volumetric configuration, wherein when said at least one of said at least partially hollow tubes moves in an axial or rotational direction, said viscous material contacts said electrically-conductive material in a second volumetric configuration; at least one magnetically-active thin film, said thin film changing its magnetic properties based on an orientation of said instrument and operatively affecting at least one electrical signal coupled to said power source; wherein said first and second volumetric configurations result in distinguishable electrical properities; and a power sink coupled with said at least two electrically-conductive tubes and said at least one thin-film-modified electrical signal through a second connection.
