The technology described herein relates to a compute module for a helmet mounted visual communication and navigation system. A compute module for a helmet mounted visual communication and navigation system may include a housing having two larger regions provided symmetrically and a smaller region provided between the two larger regions, an internal compute subassembly including a printed circuit board assembly (PCBA) having two wider portions corresponding to the two larger regions of the housing and a narrower portion corresponding to the smaller region of the housing, heat sinks configured to store heat dissipated from electronic components of the internal compute subassembly, a cable connection interface, and a power button. The compute module also may include an antenna or other sensor for receiving and transmitting data associated with a user.

A transfer rack is provided, including a rack, a pushing mechanism, and a stabilizing mechanism. The rack includes a base, a vertical plate, and hanging rods. The hanging rods are hierarchically hanged above the base. The pushing mechanism includes a push plate and a first power component connected with the push plate. The push plate has through-holes matched with the hanging rods, the push plate is slidably arranged on the hanging rods through the through-holes, and the first power component is provided to drive the push plate to move the goods to be transferred. The stabilizing mechanism includes support pillars, support beams, and second power components. The support beams cross the hanging rods under layers of the hanging rods respectively, two ends of one of the support beams are connected with the support pillars, and the support beams are lifted and lowered under driving of the second power components.

Provided are a systems and methods for continuously providing a metal wire to a welding torch for manufacturing objects by solid freeform fabrication to provide continuous deposition of metal to the freeform object, especially objects made with titanium or titanium alloy wire.

Pull carts configured for holding, transporting, and storing spools of wire or cable. A cart includes an A-frame truss comprising a plurality of crosswise beams, wherein the plurality of crosswise beams comprises: a proximal end attached to a cart base, and a distal end opposite the proximal end, wherein the distal end forms an apex of the A-frame truss. The cart includes a rod support configured to receive a spool crossbar, wherein the rod support is disposed at the apex of the A-frame truss.

A winch system for tightening and tensioning barrier cables for cable barrier systems includes a fairlead vertically movable with respect to the winch assembly. The winch system is connected to a base frame that can be attached to a vehicle for moving and for providing power to the winch and movement of the fairlead. The vertically movable fairlead allows each barrier cable to be positioned and tensioned while supported by the post of the cable barrier system to avoid damage to the posts and negatively impacting the operational strength of the cable barrier system.
