New micro brushless motors from Sanyo DC Micro Motor Division feature a ceramic air bearing design and frictionless, quiet, high-speed operation. The design eliminates the need to lubricate with oil, which tends to break down over the life of the motor. A 20 mm-size motor is available, with a 14 mm-size model to come. The motor has already been applied in a rear projection television color wheel, because it runs at high speeds and temperatures and is very quiet. It is also suitable for medical applications requiring high-reliability where an out-gassing oil bearing might cause an unacceptable level of contamination.
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.
