Part two of our “Tough as Glass” series. Cooktops see a lot of action. These glass surfaces must survive extreme temperature fluxes, heavy pots and pans, and daily wear for decades. For those reasons, the test methods used to measure the strength of glass-ceramic closely resemble everyday situations. Glass-ceramic behaves differently depending on the shape and contact area of the impact item. Therefore cooktops are tested with a compact ball impactor and a flat pan impactor.
We’ve spent years in the lab running test after test to ensure the safest and most durable glass-ceramic cooktops on the market. But don’t take our word for it — see for yourself how world-class glass-ceramic is tested.
3D volumetric displays will help to keep our nation secure
History teaches that to observe, and then to understand, is the first step to victory. At one point a wooden horse full of Soldiers was all you needed to sack a city. Too bad the Trojans didn’t have today’s imaging technology — the Greeks never would have made it past the gate. But even today’s advanced sensor technologies, which produce all manner of 3D sensor data streams, challenge our ability to interpret and understand the available raw 3D data due to the limitations of 2D displays. 3D volumetric displays could give warfighters a glasses-free, full color, high-resolution three-dimensional perspective of the battlespace — on, above, and even below it, depending on the environment. The next big advance could provide the most comprehensive view yet.
