Speedy rechargers are helping in the search for truth — honest. Lafayette Instrument Co. has developed the first portable lie detector, employing Bluetooth modules so there's far less bulk to carry. Wireless data acquisition modules make testing less conspicuous to subjects and keep the weight of five modules under a pound. Those modules can be quickly recharged in case examiners want to test many people. The battery-charging system recharges up to eight Lithium-Ion batteries in just two hours. Microchip's MCP73863 manages the charging system.
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.
