MicroSystems, Inc.'sA8515 device has advanced
protection features to provide optimized viewing. It integrates a current-mode
boost converter with internal power switch and two current sinks.
boost converter can drive up to 24 LEDs at 120 mA. The two LED
current sinks can also be paralleled together to achieve LED currents up to
240 mA. This new device can operate from a single power supply from 5 to
40V. The low 720 mV regulation voltage on LED current sources reduces
power loss and improves efficiency. A comprehensive fault table is included in
the datasheet to describe the leading-edge performance and protection features
of the A8515. It also integrates a driver for an (optional) external input

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.
