Electronics introduces a new series of insulated low-profile Coin Cell Retainers
designed to protect the battery from shorting if inserted incorrectly. These
new retainers also allow the user to stack two 20 mm cells on top of each other
to achieve 6V of power from the same board footprint or for single cell 3-V
applications. The retainers are rugged yet lightweight, with clearly marked
polarity, and are designed for both lead free solder and traditional reflow
processes. The solder tails, located outside the insulating material, support
visual inspection systems. There are no other battery-holder products like it
available on the market with the durability and design flexibility.
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.
