ABSTRACT:
This invention discloses a system which automatically determines not only a distance from an object surface, but also an orientation of the device with respect to the object surface. This invention also discloses an arrangement of three or more position sensors for determining the orientation of the device, as well as the distance of the device from the object surface. Furthermore, this invention discloses a method of using parameter computation equations for determining the orientation and the distance of the device with respect to the object surface.
