If researchers at the Georgia Institute of Technology have their way, law enforcement officials will soon detect terrorists, kidnappers, and other bad boys through walls and doors with a new radar flashlight.
The radar device sends out electromagnetic energy and then detects a return signal that indicates the presence of persons from their breathing. Results are displayed as bar graphs on a display, which rise and fall in rhythmic response to respiration of the person on the other side of the wall.
The device works through brick, wood, plasterboard, glass, and concrete walls up to eight inches thick, and at distances of up to approximately 10 ft. The Georgia Institute of Technology filed a patent for the device.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
