  • Patent number: 11414985
    Abstract: Tools and methods are described to measure dimensions of wellbores. Downhole caliper tools include a downhole collar and an uphole collar having a running position and a sensing position. The uphole collar is farther from the downhole collar in the running position than in the sensing position. A caliper sensor assembly includes: a sensor module defining tracks extending parallel to an axis of the caliper tool, the sensor module positioned towards an uphole end of the caliper tool relative to the uphole collar; and a caliper disposed between the downhole collar and the uphole collar including: a flexible mesh extending from the downhole collar to the uphole collar. Movement of the uphole collar from the running position to the sensing position axially compresses and radially expands the flexible mesh. The annular sensor module can measure dimensions of the flexible mesh relative to the axis of the caliper tool.

  • Patent number: 11415412
    Abstract: A measurement probe is described that includes a probe body, a stylus that is deflectable relative to the probe body, and a plurality of sensor elements for generating a sensor signal indicative of stylus deflection. An analyser is provided, optionally as part of a trigger unit, to analyse the sensor signals and issues a trigger signal to indicate the stylus has contacted an object. The analyser is arranged to combine a plurality of the sensor signals to generate a resultant deflection signal for comparison to a deflection threshold and is also arranged to detect oscillatory motion of the stylus by analysing at least one of the sensor signals. The analyser only issues a trigger signal when the resultant deflection signal crosses the deflection threshold and no oscillatory motion of the stylus is detected. The measurement probe may be used on a machine tool or other coordinate positioning apparatus.

  • Patent number: 11378395
    Abstract: An electro-optical level employs a bubble tube with opposite first and second ends. First and second light emitters are disposed respectively beyond the first and second axial ends of the tube and direct light toward the ends of the bubble in the tube. Electro-optical detectors are aligned substantially parallel to the axis of the tube and are spaced from the tube. First and second beams from the respective first and second light emitters scatter as the beams impinge upon the bubble. However, the scattered light from each light emitter will form a bright spot on the respective electro-optical detector at a point corresponding to the end of the bubble. The locations of the bright spots are detected by the electro-optical detectors and precisely determine the locations of the opposite ends of the bubble regardless of dimensional changes of the tube or the bubble due to temperature variations.
