Generally, the subject matter disclosed herein is directed to devices and methods for energizing and detecting a wave-energizable apparatus on an item movable with respect to a working surface of a drilling rig. One illustrative device disclosed herein includes at least one mat adapted to be positioned on a working surface of a drilling rig and a plurality of spaced-apart energizing apparatuses operatively coupled to the at least one mat. Additionally, each of the plurality of spaced apart energizing apparatuses of the disclosed device is adapted to energize a wave-energizable apparatus attached to an item that is movable adjacent to the mat and relative to the working surface.

Drilling rigs with apparatus identification systems and methods

A link member (e.g. a chain link or an elevator link) having a body, the body having two spaced-apart ends, wave-energizable apparatus (one or more) on the link body, and, in one aspect, a wrap or wraps securing the wave-energizable apparatus to the link. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 C.F.R. 1.72(b).

Chain with identification apparatus

A screen apparatus, which in certain aspects is a screen apparatus having a support, screening material on the support, and energizable identification apparatus on (exteriorly, interiorly, and/or within) the support for identifying the screen apparatus; a vibratory separator with such a screen apparatus; and a vibratory separator or shaker with energizable identification apparatus.

Shale shakers and screens with identification apparatuses

A member having a body, the body having two spaced-apart ends, wave energizable identification apparatus which, in one aspect, is radio frequency identification apparatus with integrated circuit apparatus and antenna apparatus on the exterior of the body, and encasement structure encasing the identification apparatus, the encasement structure, in certain aspects, including one or a plurality of layers of heat resistant material and, in certain aspects, at least one layer of heat resistant material, and methods for producing such a member.

Apparatus identification systems and methods

A system for measuring inner diameter of a tubular, e.g., but not limited to, a riser or a pipe, the system including at least one linear distance measuring device movable through a hollow tubular, a main body also movable through said tubular, the at least one linear distance measuring device mounted on the main body, and the at least one linear distance measuring device for producing a measurement signal indicative of a measurement of inner diameter of the tubular.

Riser and tubular inspection systems

A testing method and apparatus detects magnetic discontinuities in a sample of magnetizable material. The apparatus may include an electric motor, a transmission, driven transport wheels, and non-driven transport wheels. Further, the apparatus includes a magnetizing device for inducing a magnetic field in the sample. A sensor unit detects magnetic stray flux from the magnetic field induced in the sample and converts the detected magnetic stray flux into a signal for processing by a signal processor.
