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.

A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
