William Grill wanted to make sure his freezer didn’t cut out and ruin his frozen food. He was concerned that when he traveled, his food could defrost and re-freeze — thus compromising his frozen steaks — without his knowledge. So, he developed a gadget that measures freezer temperatures, keeps a history of variance and sends an alarm if freezer temperatures rise above a set range. The gadget is built around a small controller, an alarm and a temperature sensor. While temperature monitors are common, Grill’s device remembers temperature variance and displays the length of time the freezer rises above the set temp. The gadget is relatively small and costs less than a couple of steaks bought on sale and stored in the freezer.
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.
