ABB Drive Operations has unveiled the "world's fastest microdrive," the ACS/140. The unit covers from 0.5 to 3 hp, as well as 230 and 460V ac, in single- and three-phase configurations. It can respond to input signal changes in as little as 9 msecs. Measuring just a fraction of the size of conventional PWM ac drives, the new ACS/140 MicroDrive includes firmware and software for commercial and industrial applications. Applications include: fans, pumps, mixers, agitators, compressors, and conveyors. It also features a standard PID controller for simultaneous control of an industrial process or HVAC application.

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.
