    摘要： A UV-mask for treating keratoconus. The UV-mask could be made by having an image representing a surface of the patient's cornea with a topography map indicating an area of abnormal corneal thickness. The image is printed onto a sheet. The sheet is cut on or around the area of abnormal corneal thickness to create a transparent window in the sheet. The sheet is further cut on or around the corneal surface to result in a UV-mask. Also disclosed is a UV-mask for use in UV-irradiation treatment of keratoconus. Also disclosed are methods of treating keratoconus in an eye of a patient using a UV-mask.

    摘要： Various disclosed nuclear magnetic resonance (NMR) logging systems and methods employ an array of antennas to provide increased resolution without sacrificing signal-to-noise ratio. Certain method embodiments include: establishing a static magnetic field (B0) with a tool moving along a borehole through a formation; concurrently driving a multiple antenna cells to produce a radio frequency field (B1) in said formation; measuring an individual response from each antenna cell as nuclear spins undergo precession in the formation; and determining at least one characteristic relaxation time of the formation based at least in part on the individual response. The individual responses can be associated with positions where the individual responses were measured, and the relaxation time can be determined from a combination of those responses associated with a given position. Certain responses may be excluded due to tool motion that degrades the measured response.

    摘要： Method and apparatus are provided to accelerate the cooling of thermally sensitive components in a chamber of a downhole instrument assembly. In accordance with the invention, a passage is formed in the chamber and a fluid is conveyed through the passage to cool the components to the desired temperature. By using the method and apparatus of the present invention the amount of time to cool the components is dramatically less than the time required for cooling using conventional techniques.
