In accordance with said control method, the transmission of the laser beam is periodically interrupted with the aid of means for masking the laser beam placed between the reference point and a source of the laser beam. A graphical user interface is electronically linked to a centralized facility remotely located from the device. The end portion has a first interlocking profile, which may be a recess or flat in the outer cylindrical surface of the anchor pin. The first cover includes a first opening exposing the connector terminals therethrough, and covers the second face. Placement of the circuit nodes at the centers of the rectangles significantly reduces the number of nodes and segments, and provides a faster yet comprehensive analysis framework.
