Systems and methods for inspecting a hole in a laminated structure. An exemplary system includes a transducer assembly configured to direct sound waves substantially parallel to a surface of the hole. The system further includes a controller that collects A-scan data for multiple rotational positions of the transducer assembly as the transducer assembly is rotated within the hole. The controller processes the A-scan data for the multiple rotational positions of the transducer assembly to generate B-scan data, and displays the B-scan data.

Embodiments of systems and methods that can facilitate data collection for valve diagnostics. The systems can include a valve assembly with a valve and a sampling device that is configured to access a repository with a first buffer and a second buffer. During operation, the valve assembly is configured to read data representing operating variables for the valve into the first buffer. The valve assembly is also configure to determine a quality measure for a first sample set of data from the first buffer, the quality measure indicating the usefulness of the first sample set of data for predicting performance of the valve relative to a second sample set of data from the second buffer. In one embodiment, the valve assembly is further configured to read data from the first buffer into the second buffer in response to the quality measure indicating that the first sample set of data is relatively more useful than the second sample set of data.

A method for determining measurement conditions of a roughness sensor having at least one measuring needle, a computer program product and a measuring device for carrying out the method are provided. The measuring needle is positioned on a surface in a rest state and rests on the surface without being moved. Measurement signals are recorded in the rest state. A signal line of the roughness sensor is electrically grounded and measurement signals are recorded in the grounded rest state. Further, a method for measuring a roughness of a workpiece surface by the roughness sensor is provided in which the measuring needle is guided along a surface section of the workpiece surface to be measured and moved in a measurement direction (x-direction). The movement of the measuring needle in a plane (yz-plane) perpendicular to the measurement direction is recorded during the movement of the measuring needle along the workpiece surface.

A method for operating a surface measuring apparatus for measuring a surface of a workpiece. Method includes operating surface measuring apparatus having a probe that includes a probe arm that is deflectable by an angle about a swivel axis, and that on its end facing away from the swivel axis bears a probe element. Probe is movable relative to a base body of surface measuring apparatus along a linear axis. In method, a workpiece is contacted by moving the probe along the linear axis by use of the probe element, and after workpiece is contacted, probe arm is moved by a specified travel distance along the linear axis. The resulting angular deflection of the probe arm about the swivel axis is measured, and based on the specified travel distance and measured angular deflection of the probe arm, the probe arm is classified with regard to its length.
