RADEX(reg)-NN steel-disc couplings provide zero backlash torque transmission and consist of machined steel hubs and a stainless-steel laminae package. This package allows angular and parallel misalignment and axial travel. Nominal torque ratings range from 130 to 79,650 lb-inches with maximum speeds to 20,000 rpm. There are 13 standard sizes with maximum shaft diameters of 4.5 inches and several hub-to-shaft clamping arrangements.
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.
