Abstract: Aspects of the inventions generally provide a method and apparatus for coupling a communication sub to a wired drill pipe. In one aspect, a surface of a coupler head is non threaded and configured to provide a retaining force. In another aspect, a coupler head is coupled to a body, and a support mechanism is coupled to the body and configured to secure the coupler head within a receiving end of the wired drill pipe. In another aspect, a method of placing a communication sub involves inserting the communication sub into the receiving end of the wired drill pipe, adjusting the position of the communication sub until an indication of signal communication between the communication sub and the wired drill pipe is observed, and after the indication of signal communication is observed, retaining the communication sub within the receiving end until removal of the communication sub is desired.

Abstract: A method for determining a drilling state of a bottom hole assembly in a wellbore includes acquiring one or more downhole sensor measurements and processing the sensor measurements using a downhole processor to determine a drilling state of the bottom hole assembly. An operating state of the bottom hole assembly may be automatically changed in response to the determined drilling state. A method for computing a dynamic drilling energy of a bottom hole assembly includes acquiring at least one sensor measurement and processing the sensor measurements to obtain at least one of (i) an energy of axial motion of the bottom hole assembly, (ii) an energy of rotational motion of the bottom hole assembly, and (iii) an energy of lateral motion of the bottom hole assembly.
