Claim 17:
18. A method of using an apparatus in a wellbore, comprising:
disposing a drill string in the wellbore, the drill string being configured to drill the wellbore, wherein the drill string includes:
a non-rotating section disposed along the drill string, the non-rotating section having a bore and at least one biasing element configured to engage 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 relative rotation between the rotating section and the non-rotating section,
at least one orientation sensor in the non-rotating section and 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;

varying a speed of the rotation of the rotating section to transmit a control signal;
using the controller to determine the control signal using the at least one relative rotation sensor;
receiving energy within the non-rotating section from the rotation of the rotating section and controlling a force and/or position of the at least one biasing element by using the determined control signal and the generated signals representative of the orientation of the non-rotating section relative to the selected frame of reference from the at least one orientation sensor.
