Abstract: A formation fluid sample is exposed to a rigidly-supported semi-permeable membrane such as silicone rubber to permit diffusion of gases and vapors from the formation fluid into a vacuum chamber, while at the same time, blocking the passage of any liquids. The membrane-transmitted gas is analyzed in the vacuum chamber by a sorbent-coated resonator. The sorbent absorbs gas and changes the resonant frequency of the resonator to indicate the presence of a gas. An ion pump or sorbent is associated with the evacuated chamber to maintain the vacuum. The ion pump or sorbent removes gases and vapors from the chamber that diffuse into the chamber from the reservoir sample that is on the opposite side of the semi-permeable membrane.

Abstract: A pressure sensor for use in measuring the pressure within fluids. The sensor comprises a medium whose material has a low coefficient of thermal expansion. The pressure can be measured by observing how signals pass through the medium at some unknown pressure and then comparing the observations to how the signals pass through the medium at a known pressure. The signals can be acoustic waves or light waves.

Abstract: A cooling system in which an electronic device or other component is cooled by using one or more solid sources of liquid vapor (such as polymeric absorbents, hydrates or desiccants that desorb water at comparatively low temperature) in conjunction with one or more high-temperature vapor sorbents or desiccants that effectively transfer heat from the component to the fluid in the wellbore. Depending on the wellbore temperature, desiccants are provided that release water at various high regeneration temperatures such as molecular sieve (220-250° C.), potassium carbonate (300° C.), magnesium oxide (800° C.) and calcium oxide (1000° C.). A solid water source is provided using a water-absorbent polymer, such as sodium polyacrylate. Heat transfer is controlled in part by a check valve selected to release water vapor at a selected vapor pressure.

Abstract: The present invention provides an apparatus and method for randomly distributing a number of fibers associated with a spectral channel over an area of an input optics head input window for sensing optical input. The head comprises a plurality of optical channels each channels having a plurality of fibers spread out and intermingled across the input optics head. Thus, a particle or gas bubble passing in front of the input optics head would temporarily affect all channels but only to a small degree since only a portion of fibers for a particular channel would be affected by the temporary passage of the bubble or particle passing in front of a particular region of the optics head input window.
