In geology, a piercing point is defined as a feature (usually a geologic feature, preferably a linear feature) that is cut by a fault, then moved apart. Reconfiguring the piercing point back in its original position is the primary way geologists can find out the minimum slip, or displacement, along a fault. This can be done on a large scale (over many kilometers), a small scale (inside a single outcrop or fault trench) or even a single hand sample/rock (see image).

Laser cladding method for strengthening surface of piercing point
ActiveCN101519778ASolve the problem of easy falling offThickness is easy to controlMetallic material coating processesPiercing pointPre treatment
A laser cladding method for strengthening the surface of a piercing point includes the following steps of: (1) prefabricating WC / Co-base cladding powder; (2) pre-processing the surface of a piercing point workpiece, and cleaning up stain and rust; preheating for 2 to 5 hours at a temperature between 400 DEG C and 600 DEG C; (3) cladding the prefabricated composite powder fed in the way of reverse synchronization or coaxially in multiple steps by a CO2 laser; simultaneously, carrying out synchronous inert gas protection on the laser-cladding area; and (4) subsequent processing. The laser cladding method adopts laser to prepare a WC ceramic particle-strengthened Co-base composite coating on the surface of the piercing point, and the coating is metallically combined with the matrix, so the binding force between the coating and the matrix is enhanced; the maximum thickness of the coating can reach a few millimeters; and as the surfaces of WC particles are coated with Ni, the absorption of laser energy by the WC can be reduced, so that the burnout rate of the WC can be reduced in a laser melting pool. The distribution of the WC particles is uniform in the coating, the rigidity of the coating is high, consequently, the service performance of the piercing point can be improved, and the service life can be prolonged.

Crowdsourcing atmospheric correction data
A system and method crowdsources atmospheric data from one or more rovers. The rovers calculate an estimated ionosphere delay value that indicates an adverse effect of ionospheric activity on signals received from the GNSS satellite. The values and identifiers may be transmitted to a server. The server utilizes the received information to generate an ionosphere map that reflects the magnitude of ionospheric delay at different locations. The ionosphere map is transmitted to one or more rovers. The rover determines if a pierce point associated with a selected GNSS satellite in view of the rover falls within the boundaries of the ionosphere map. If so, a corresponding ionosphere delay value is obtained utilizing the ionosphere map and then applied as a correction to account for ionospheric activity. In addition, the central server and / or rover may transmit the estimated ionosphere delay values and identifiers to other rovers.
