An aircraft that includes a helicopter drone on which a 3D scanner is mounted via an actively rotatable joint is provided. The 3D scanner has at least one high-resolution camera for recording a multiplicity of overlapping images of the object from different recording positions and recording directions, so that comparison of the images allows a position and orientation of the 3D scanner relative to the object to be ascertained. In addition, the aircraft has a coordination device for coordinated control of the 3D scanner, the joint and the helicopter drone. The system for damage analysis has an aircraft and an image processing module generating a data representation of a surface profile of the object on the basis of the recorded images. In addition, the system includes a rating device for checking the surface profile and for outputting a damage statement on the basis of the check.

An apparatus for detecting a transient event in an operating machine, the apparatus comprising: a controller configured to control performance of the following steps: a measurement step comprising measuring a periodic signal from a machine; a processing step comprising synchronously processing the periodic signal to track the primary frequency; a filtering step comprising removing the primary periodic component and its harmonics from the periodic signal to yield a filtered dataset; an integration step comprising integrating the filtered dataset over the remaining frequencies to yield an integrated dataset representing the periodic energy at frequencies other than the primary frequency and its harmonics; an analysis step comprising identifying a short-term transient in the integrated dataset to identify a transient disruption in the operation of the machine.

A wiring sheet includes one or more carbon wires each of which is one of a signal line and a power supply line, and which are conductors including carbon as a main material and have flexibility; and an insulation sheet that encloses substantially an entirety of the one or more carbon wires, includes an electrical insulator as a main material, and has flexibility.

A system for monitoring the performance of a multi-stranded tensile member where a portion of the strands are concealed within a termination. The invention provides a monitoring system that allows the user to determine when one or more of the strands has degraded to a point of concern. In some embodiments the monitoring system depends on visual inspection and in other embodiments the monitoring system is automated.

A structural vibration monitoring method based on computer vision and motion compensation provided in the present disclosure adopts a dual-camera system for self-motion compensation. The dual-camera system consists of a primary camera and a secondary camera rigidly connected to each other. The primary camera directly measures a structure displacement. This method inevitably includes an error generated due to motion of the primary camera. Meanwhile, the secondary camera measures displacements of translation and rotation, so as to estimate a measurement error caused by the motion of the primary camera. Then, with the displacement directly measured by the main camera minus the measurement error, a corrected structure displacement is obtained, thereby truthfully and accurately monitoring vibrations of a bridge structure.

A method and system for conducting a non-contact survey of an overhead crane runway system using a survey apparatus that is alternately located in the crane bay or on a crane bridge girder. Disclosed more particularly are a method and system for testing an overhead crane runway beam 3D alignment or an overhead crane runway rail 3D alignment using a 3D laser scanner.
