The Polymaster(reg) ET automatic polymer blending system uses the motor-driven "Gatlin" distribution head, which hydraulically segments polymers into ultra-thin film platelets for maximum activation. The high-performance mixing and diluting system can handle high molecular weight liquid polymers and can deliver a diluted polymer solution at rates up to 50 gals/min. Applications include paper making and industrial and municipal water and wastewater treatment.

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.
