摘要： A system for communicating with a downhole network integrated into a downhole drill string is disclosed in one aspect of the invention as including a data transmission coupler mounted to a downhole tool and adapted to transmit data across a tool joint. The data transmission coupler is also capable of transmitting data by emitting electromagnetic radiation. An antenna is focused at and positioned within sufficient range of the data transmission coupler to detect the electromagnetic radiation and receive the data. This data may then be transmitted to a receiver or other equipment. In certain embodiments, the antenna is located above ground level and may be mounted to a swivel, derrick, hoist system, kelly, or other structure. The antenna is ideally mounted to a structure which is out of the way of equipment and workers working on the drill string.

The working face has at least three fixed blades converging towards a center of the working face and diverging towards a gauge of the bit, at least one blade having a cone region adjacent the center of the working face. The cone region increases in height away from the center of the working face and towards a nose portion of the at least one blade. An opening is formed in the working face at the center of the bit along an axis of the drill bit's rotation, the opening leading into a chamber with at least one wall. An indenting member is disposed within and extends from the opening, is substantially coaxial with the axis of rotation, and is fixed to the wall of the chamber.
