The new Allen-Bradley Kinetix 7000 servo drive provides a safe-off capability integrated into the drive to increase safety and maximum machine availability. Tasks such as machine setup, cleaning, removal of jams and other typical maintenance tasks that previously required power-down conditions can now be accomplished without removing power from the entire machine. The drive output is disabled to eliminate motor torque, providing safety and maximum machine availability. The result is faster machine restart and shorter machine downtime. Safety connection systems, which reduce wiring and ease troubleshooting, simplify use of the safe-off capability in multi-axis applications. Automatic diagnostics and safety circuit status information are available at the Logix controller. The Kinetix 7000 integral safety solution is certified by TUV and meets the requirements of EN-954-1 Category 3 and IEC-61508 SIL 3.

For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
Green energy is being billed as a way to make communities that are energy deprived more self-sustaining. So it makes sense to use natural materials to create devices that harvest this type of energy. That’s the idea behind a hybrid wind/solar energy harvester made of bamboo that’s been developed by UVM researchers.
