The SD-15900 two-speed synchro or resolver combiner works in conjunction with any two synchro- or resolver-to-digital converters. The SD-15900 device combines the digital information from the coarse S/D channel and the digital information from the fine S/D channel, resulting in up to 22 bits of angular data. The combiner and S/D converters can be powered by a single 5V dc power supply. The small size of the components and the high accuracy obtainable with two-speed combinations make the combiner targeted for use in high-performance military and industrial position-control systems.

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.
