摘要： A method of analyzing acoustic data, that includes determining fluid sound speed through connate fluid. The method involves sampling the fluid, sending an acoustic signal into the fluid between a first and a second reflective interface. Data is recorded that represents acoustic signals over time as they are reflecting from the interfaces. A smoothed first derivative with respect to time of the cumulative sum of squares (CSS) of the filtered amplitude data is determined. This first derivative is cross correlated to the time-shifted versions of itself.

摘要： 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.

摘要： A method for determining orientation of an instrument with respect to earth's gravity. The method includes measuring components of earth's gravity along mutually orthogonal axes. One of the axes is substantially parallel to an axis of the instrument. Tilt of the instrument along two orthogonal axes is measured. One of the tilt axes is substantially parallel to the instrument axis. The instrument is rotated about its axis, and biases of the sensors used to measure the components of earth's gravity perpendicular to the instrument axis are calculated by averaging measurements made by these sensors during rotation. The ratio of gains of these sensors is determined from the range of amplitudes of the output of these sensors during rotation. A roll angle is determined from the bias corrected measurements of components of the earth's gravity perpendicular to the axis. The tilt measurement with respect to the two orthogonal axes is then calibrated by using the calculated roll angle. Gain and offset calibration of all the sensors used to measure the components of the earth's gravity is performed using the calibrated tilt measurements and the orientation is calculated from the gravity measurements after correction for gain and offset of the sensors.
