A wire for geotechnical use is described, for making protecting nets, made of high strength steel. The wire is at least partially shaped in a waveform and has a plurality of crests and valleys arranged alternately one to another. A protecting net is also described, usable in the geotechnical field, having a wire at least partially shaped in a waveform for making the mesh, and/or as a reinforcing element of the net. An anchoring device, a guywire and an energy dissipating device are also described, each having a plurality of wires at least partially shaped in a waveform.

A machine for forming RFID antennas includes a support structure provided with a support for an RFID substrate and a plurality of forming pegs having vertical axes fixed with respect to the support and arranged above it to define a predetermined path for a wire configured to form the RFID antenna The machine has a wire feeding system that has a wire guide element and a handling assembly, a pair of grippers arranged at ends of the path and operable to assume a closed position, in which the wire is blocked, and an open position, in which the wire is released, and a movable structure carried by the support structure and provided with a thrust element movable vertically between an upper position in which it allows the wire to be wound around the pegs and a lower position in which it deposits the formed antenna on the substrate.

An electrode having a plurality of connected strands retained by a current collector is described. A connected strand has first and second ends that are retained by a current collector, and may be retained at different locations along the length of the current collector. A connected strand retained by the current collector in substantially the same location along the current collector, is a looped strand. A connected strand provides two paths for current to move through the strand to the current collector and may therefore provide lower resistance than a free strand having only one end coupled to the current collector. Furthermore, a connected may move less as a function of fluid forces and retain more bio-film in turbulent conditions than free strands. Finally, a connected strand has no free extended end and therefore is less likely to puncture through an ion conductive membrane.

A cable bending system comprises at least one bending module. The bending module includes an active actuator having a first body, and an active rod mounted in the first body. The active rod is movable in a first direction perpendicular to an axial direction of a cable to be bent. A passive actuator of the bending module includes a second body connected to the first body and defines a shaping cavity open to the active rod. The active rod pushes a portion of the cable into the shaping cavity of the second body in the first direction for bending the portion of the cable.
