MagneTek's microsize GPD 205 adjustable frequency drives are now available in 460V ac models. The new models come in four incremental ratings from 0.5 to 3 hp. Although only a fraction of the size of conventional PWM drives, the GPD 205 is said to be useful for sophisticated equipment control in applications that include fans, pumps, mixers, agitators, compressors, conveyors, commercial laundry, and material-handling installations. The drive's 16-bit microprocessor provides the flexibility, features, and performance for a wide range of operational requirements. It installs and programs easily, has the versatility to adapt to simple or complex applications, and is UL-listed, CSA-approved, and CE-marked. MagneTek Drives & Systems. Product Code 4361
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.
