Abstract

A degradation assembly may comprise at least one sensor mounted on a pick; the pick comprising a first conductor in communication with the sensor. The assembly may also comprise a receiving element including a bore comprising a second conductor. The first and second conductors may combine to create a connection as the pick is inserted into the bore of the receiving element.

First claim

What is claimed is:

1. A drilling apparatus, comprising:
at least one sensor mounted on a cutting assembly, wherein the cutting assembly is at least partially formed of a diamond material;
the cutting assembly comprising a first conductor in communication with the sensor; and
at least one receiving element including a bore comprising a second conductor;
wherein the first and second conductors form a stab connection as the cutting assembly is inserted into the bore of the receiving element.

2. The apparatus of claim 1 , wherein the first and second conductors comprise surfaces that directly contact to form the stab connection.

3. The apparatus of claim 1 , wherein the stab connection is releasable.

4. The apparatus of claim 1 , wherein the bore of the receiving element comprises an inside surface that is complementary to an outside surface of the cutting assembly.

5. The apparatus of claim 4 , wherein the complementary inside surface and outside surface are tapered.

6. The apparatus of claim 1 , wherein the receiving element is selected from the group consisting of blocks, sleeves, holders, and spring clips.

7. The apparatus of claim 1 , wherein an insulation material surrounds the first conductor and second conductor.

8. The apparatus of claim 1 , wherein the at least one sensor is selected from the group consisting of strain gauges, accelerometers, thermocouples, and magnetometers.

9. The apparatus of claim 1 , wherein the cutting assembly comprises a shank and the at least one sensor is disposed within the shank.

10. The apparatus of claim 9 , wherein the shank comprises an annular recess.

11. A drilling apparatus, comprising:
at least one sensor mounted on a cutting assembly, wherein the cutting assembly is at least partially formed of a diamond material;
the cutting assembly comprising a first conductor in communication with the sensor; and
at least one receiving element including a bore comprising a second conductor;
wherein the first and second conductors form a connection as the cutting assembly is inserted into the bore of the receiving element, wherein the at least one sensor is powered by an external power source.

12. The assembly of claim 11 , wherein the connection comprises a stab connection.

13. The assembly of claim 11 , wherein the connection comprises an inductive coupling.

14. The assembly of claim 11 , wherein the connection comprises flat contact surfaces.

15. A drilling apparatus, comprising:
at least one sensor mounted on a cutting assembly, wherein the cutting assembly is at least partially formed of a diamond material;
the cutting assembly comprising a first conductor in communication with the sensor; and
at least one receiving element including a bore comprising a second conductor;
wherein the first and second conductors form a connection as the cutting assembly is inserted into the bore of the receiving element, wherein the cutting assembly comprises a shank and the at least one sensor is disposed within the shank, the shank including an annular recess having a clamp ring disposed within the annular recess.
