ABSTRACT:
A system for accurately locating upon a surface any number of finite points, recording those locations together with such additional information as is desired to be applied to the surface, and then transferring such recorded information to that surface in defined relation to the recorded point locations. The point locator incorporates a pair of potentiometers positioned to provide output signals representative of both X and Y coordinates, the locating signals being generated responsive to movement of a cursor head connected to the potentiometers through an extensible potentiometer rotating means to thereby actuate one or both potentiometers in amounts representative of a series of given X-Y cursor positions.
