Abstract: An illustrative seismic while drilling system includes a drill string having at least one seismic sensor that can be employed to detect seismic signals during pauses in the drilling process, e.g., when extending the length of the drill string. An embedded processor digitizes a signal from the seismic sensor to obtain a digital waveform and processes the digital waveform to derive a compressed waveform representation for storage or transmission.  Compression is provided by adaptively reducing the sampling rate and quantization resolution subject to one or more quality constraints including, e.g., error in first break timing, error in first break sign, mean square error, and bit count. Reasonably good representations of the received acoustic waveforms can be achieve with less than 200 bits.

Abstract: A method of preparing or operating a mass spectrometer vacuum interface comprising a skimmer apparatus (160) having a skimmer aperture and an internal surface (162) of the skimmer apparatus, comprising disposing an adsorbent or getter material (170) on the internal surface. The internal surface has a deposition region where matter from plasma flows may be deposited and the material is disposed on part or all of the deposition region. The disposing step may be performed before a first use and/or intermittently, especially to refresh a previously disposed material. Providing such material serves to trap or collect deposition matter which might anyway be deposited but in such a way that subsequent liberation of that matter is prevented or at least reduced. It can also serve to cover over or 'bury' matter deposited up to that point, to effectively prevent or significantly hinder subsequent liberation thereof into the plasma flow. It may serve to refresh an earlier provision of material, to help to maintain its adsorptive/trapping effect.

Abstract: Flow and product waste water from fracturing can be cleaned and reused utilizing a precipitation methodology incorporating, in part, a super critical reactor (30). Initially, the waste water is treated to remove solids, destroy bacteria, and precipitate out certain salts, such as barium, strontium, calcium, magnesium and iron. The waste water then can be passed through a radioactive material adsorption unit (20) to remove radium, as well as other radioactive materials, and then introduced into the super critical reactor (30). The super critical reactor is designed to bring the waste water to super critical conditions at a central portion of the reactor. This causes any dissolve solids, in particular sodium chloride and the like, to precipitate out of solution in the center (42) of the reactor (30) thereby avoiding scale formation on the walls of the reactor. A catalyst can be utilized to promote the breakdown of carbon bonds.
