An advanced digital optical inspection system is used on three insert injection-molding machines. These real-time inspection systems prevent improper loading of inserts and ensure that they are loaded. The systems feature three different types of optical sensors for specific applications. One uses fiber optics and infrared light, which filters out interference of ambient lighting; another is a laser-detection system which can focus a split-second light beam on a part less than 0.25 mm in diameter; the third system employs compact digital cameras with built-in processors.
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.
