Claim 0:
1. An apparatus for use in a wellbore, comprising:
a drill string configured to drill the wellbore;
a non-rotating section disposed along the drill string, the non-rotating section having a bore and at least one biasing element engaging a wall of the wellbore;
a rotating section disposed in the bore of the non-rotating section;
at least one relative rotation sensor configured to generate signals representative of a rotation of the rotating section relative to the non-rotating section;
at least one orientation sensor within the non-rotating section configured to generate signals representative of an orientation of the non-rotating section relative to a selected frame of reference; and
a controller in signal communication with the at least one relative rotation sensor and the at least one orientation sensor, the controller being configured to adjust at least one of: (i) a force applied by the at least one biasing element, and (ii) a position of the at least one biasing element, the adjusting being in response to the generated signals representative of a rotation of the rotating section relative to the non-rotating section from the at least one relative rotation sensor and the generated signals representative of an orientation of the non-rotating section relative to the selected frame of reference from the at least one orientation sensor, wherein the controller is configured to receive information from the rotating section by a signature of rotations of the rotating section, wherein the at least one biasing element is energized using energy received within the non-rotating section from the rotation of the rotating section.
