    Heavy construction equipment is usually used due to the amounts of material to be moved — up to millions of cubic metres. Earthwork construction was revolutionized by the development of the scraper and other earth-moving machines such as the loader, the dump truck, the grader, the bulldozer, the backhoe, and the dragline excavator.

    Because these probes generally acquire one point at a time and at high sample speeds, acquisition of long (continuous) surface profiles is possible. Scanning can take place in hostile environments, including very hot or cryogenic temperatures, or in radioactive chambers, while the detector is located at a distance, in a human-safe environment ...

    Using the bottom track feature, the track of the boat as well as the cross sectional area is estimated after adjustment for left and right bank areas. The discharge can then be calculated as the dot product between the vector track and the current velocity. The method is in use by hydrographic survey organisations across the world and forms an ...

    He hired five employees in 1961. [8]: 26 Bently Nevada was the first to successfully apply eddy-current technology for use in non-contacting displacement sensors. This type of electronic sensor is typically used to measure very small distances between the tip of the sensor and a conductive surface, such as rotating shaft. [13]
