    摘要： Apparatus and method for inspecting a tubular member for degradation, which tubular member may be a control rod drive mechanism (CRDM) penetration tube of the kind typically found in nuclear power reactor pressure vessels. The CRDM penetration tube includes a thermal sleeve concentrically disposed therein, the sleeve being radially rotatable and axially translatable within the tube. However, the sleeve may be nonhomogeneous, which nonhomogeneity could undesirably mask the inspection signal as the inspection sensor is radially and axially moved in order to inspect the tube. The apparatus includes a support body sized to be disposed in the sleeve, an expandable bladder connected to the support body to engage the sleeve for securing the support body to the sleeve, one or more sensors connected to the support body for sensing the degradation in the tube, and a rotator connected to the support body for simultaneously rotating the support body, the bladder, the sensor and the sleeve in the tube to radially scan the tube. A pusher/puller mechanism is also provided, the pusher/pusher mechanism being connected to the support body for simultaneously translating the support body, the bladder, the sensor and the sleeve to axially scan the tube. As the support body is rotated and translated, the sleeve is stationary with respect to the sensor because the bladder secures the sleeve to the support body; thus, as the support body, and the sensor connected thereto are rotated and translated, the sleeve will be rotated and translated to a like extent. In this manner the material properties of the sleeve are radially and axially invariant relative to the sensor, for obtaining a more precise inspection of the tube.

    摘要： A method and apparatus for securing or attaching a rotor blade with a turbine rotor cavity by disposing an expanding material between the blade root and the cavity walls. The expanding material comprises a naturally occurring mineral which expands to a great degree when exposed to elevated temperatures. The expanding material may be provided in the form of shims made directly from the expanding material or made from a composition of the expanding material and a binder such as a polymer or elastomer. Alternatively, the expanding material may be provided in the form of a liquid vehicle applied to surfaces of the cavity walls. The expanding material is located at specific positions within the cavity to urge certain surfaces of the blade root against certain surfaces of the cavity walls. In this manner, the blade can be forced into a tight fit and an aligned position, with respect to the rotor, upon expansion of the expanding material.

    摘要： A method for processing thermography signals. A time series of radiometric data is measured from a surface (104) of an object (102) over a period of heating and subsequent cooling, and a mathematical curve (1, 2) is fit to the data. An amplitude aspect and one or more shape aspects are identified for each curve. The amplitude and shape aspects are then used together to characterize features such as defects in the object. The amplitude and shape aspects for an array of such data may be combined in a single noise-free visual display (100) by associating hue (color) with the shape aspect and luminance (brightness) with the amplitude aspect. Optionally, a second shape aspect may be identified and associated with saturation on the display. A visible image of the object may be overlaid on the display.

    摘要： A method of coalescing information about inspected objects. The method includes acquiring an image set of an object to be inspected, the image set having a three-dimensional model of the object and a plurality of two-dimensional images of the object. A location of interest is identified on a surface of the modeled object and global coordinate points of the three-dimensional model are designated that characterize the location of interest of the modeled object. A markup tag annotating the location of interest is associate with the designated global coordinate points of the three-dimensional model, and the markup tag is conveyed when viewing any one of the plurality of two-dimensional images of the image set that have at least one image point that correlates to a corresponding designated global coordinate point of the three-dimensional model that characterize the location of interest.

    摘要： A method of using a Graphic User Interface (GUI) for interactive virtual inspection of modeled objects. The method includes acquiring a three-dimensional model of a modeled object and displaying a first view of the modeled object for a user to identify locations of interest on a surface of the modeled object visible within the first view. The user enters information to create a markup tag that annotates the location of interest, and the markup tag is automatically associated with the location of interest on the modeled object. A second view of the modeled object is displayed including the user identified location of interest and the markup tag.
