    • Disclosed is a method for estimating a geometry of a borehole penetrating the earth. The method includes: performing a plurality of borehole caliper measurements with N transducers at a plurality of times, wherein for each time a measurement set comprises measurements made by the N transducers at that time; dividing a cross-section of the borehole into S sectors; obtaining an estimate of the borehole geometry by connecting representative radius points in adjacent sectors; displacing each measurement set according to a displacement vector related to an offset of each measurement set from the estimated geometry if the displacement vector exceeds a selection criterion; iterating the obtaining an estimate of the borehole geometry and the displacing each measurement set based on a latest displacement vector; and providing a latest obtained estimate as the geometry of the borehole when all of the displacement vectors no longer exceed the selection criterion for the displacing.
    • 公开了一种用于估计穿透地球的钻孔的几何结构的方法。 该方法包括:用N个换能器多次执行多个钻孔卡尺测量,其中每次测量集合包括此时由N个换能器进行的测量; 将钻孔的横截面分成S个扇区; 通过连接相邻扇区中的代表性的半径点来获得钻孔几何形状的估计; 如果位移矢量超过选择标准,则根据与每个测量集合的偏移量有关的位移矢量从估计的几何图形移位每个测量集合; 迭代获得钻孔几何形状的估计以及基于最新位移矢量来移位每个测量集合; 以及当所有位移矢量不再超过用于位移的选择标准时,提供最新获得的估计作为钻孔的几何形状。

    • The present invention relates to an apparatus for a cleaning carriage (2, 102) for rinsing, cleaning and wringing out a mop. More precisely, the apparatus comprises a mop container (6, 106, 202) having connecting sidewalls, a mop-wringing device (14, 50, 116), and also a collecting bowl (24, 52, 124, 200) arranged at the mop container to which cleaning agent is added through a separate vessel for rinsing and cleaning of the mop in the collecting bowl, the collecting bowl (24, 52, 124, 200) comprises liquid-sealed interfaces such that cleaning agent can be filled up in the collecting bowl for rinsing and cleaning of the mop, and also that devices (32, 66, 166, 206; 36, 56, 122, 172, 210) are arranged in connection to the collecting bowl for emptying of the same. The present invention also relates to a method and a use.
