Abstract: An environmentally controlled enclosure for a musical instrument that continuously monitors and increases and decreases humidity levels within the enclosure as needed to maintain a humidity level selected for the purpose of preserving the musical instrument stored therein. The enclosure is particularly useful in protecting and preserving musical instruments having one or more component parts made of wood, which is particularly sensitive to abrupt changes in humidity and to exposure to humidity extremes. The enclosure is provided with a sensor for monitoring humidity levels that is operably connected to a control unit for controlling the equipment for increasing and decreasing the humidity within the enclosure.

Abstract: A method and apparatus for determining abnormal pressure zones of a geologic formation using NMR measurements, preferably for logging-while-drilling applications. In a preferred embodiment, a normal compaction trend is constructed using NMR-derived clay bound water volume (CBW) content for non-consolidated subsurface formations or bulk volume irreducible (BVI) and CBW for consolidated formations versus depth. Deviations from this normal compaction trend are used to indicate the presence of shale sections with higher porosity that directly corresponds to an overpressured top seal or transitional zone.
