Some embodiments of the disclosure provide a flatness detection device. In an embodiment, the flatness detection device includes a back plate, an electromagnet, a cross beam, a probe, and a limiting frame. The limiting frame and the electromagnet are provided side by side on the back plate. The cross beam is located above the limiting frame and the electromagnet. The probe vertically penetrates the cross beam and the limiting frame. A spring is provided between the cross beam and the electromagnet. The spring is movable in a vertical direction by a guide, the movement being at least one of compression and extension.

A location and governance system and method for light electric vehicles that includes on-board sensors and receivers for providing readings used to compute absolute and relative vehicle position information, and combining the absolute and relative position information to compute a determined vehicle position, and a current surface type being traveled on by the vehicle. Governance commands for the vehicle can be generated based on the current surface type. Positioning system receivers, inertial measuring units, cameras and other sensor can be used. Vibration analysis, image processing, transition detection and other methods can be used to determine vehicle position and surface type, and spatial databases and other resources can be used. Determining a current surface type the vehicle is travelling on can include determining whether the vehicle is traveling on a sidewalk.

A laser collimation- measuring system, including: a first laser source; a second laser source; a light combining device; a collimator; and a light divergence device. The first laser source and the second laser source emit a first laser and a second laser, respectively, to the light combining device. The first laser and the second laser are transmitted through the light combining device as a third laser and a fourth laser, respectively, and the third laser partially overlaps the fourth laser. The collimator is disposed in a light path of the third and fourth lasers and positioned between the light combining device and the laser divergence device. The laser collimation-measuring system enhances intensity of the laser collimation-measuring system.

A topographical measurement system uses an imaging cartridge formed of a rigid optical element and a clear, elastomeric sensing surface configured to capture high-resolution topographical data from a measurement surface. The imaging cartridge may be configured as a removable cartridge for the system so that the imaging cartridge, including the rigid optical element and elastomeric sensing surface can be removed and replaced as a single, integral component that is robust/stable over multiple uses, and easily user-replaceable as frequently as necessary or desired. The cartridge may also usefully incorporate a number of light shaping and other features to support optimal illumination and image capture.

The present invention relates to a system and process carried out after a process of separating fragments of steel from pieces of ore that come out of a semi-autogenous grinder for grinding ores, and which consists of a system formed by one or more instruments for capturing images, each one being sensitive to light of different wavelengths, which point to the surface of an element for receiving the steel fragments or a channel that receives the steel balls and the fragments thereof from the separation process, through which the steel balls and fragments thereof move when they are discharged from this process, with the possibility of directing each image sensor such that it is not parallel to the others.

By digitally processing the images obtained with the one or more sensors, the dimensions and morphology of the balls and ball fragments discharged from the separation process can be determined.
