Pressure ulcers can be a serious problem for those suffering from lower-body paralysis. Lack of sensation means these patients aren't prompted to shift in response to building pressures, and that in turn leads to ulcers. An answer is now available in the form of a sensitive mat that alerts users when undue pressure is building in a given area.
A new nozzle designed with fluid simulation technology paired with a process that deposits powdered metal and delivers a laser beam are behind a 10-fold increase in speed for Toshiba's new 3D metal printer. The company says the printer can also turn out larger structures at a lower cost than current printers.
Boeing and Airbus each predict a bright near-term future for airliners but differ sharply in the types of aircraft for which they expect to see the most demand. Boeing favors smaller, single-aisle passenger planes and cargo haulers, while Airbus is staking its future on double-aisle passenger models to serve growing traffic between mega-cities.
In addition to the rich contributions in art, math and the sciences that ancient Greece passed on to Western Civilization, the Greeks also appear to have produced the world's first mechanical calendar computer called the Antikythera Mechanism. This article explains how it works, new findings and includes diagrams.
Aircraft maintenance will be airborne with performance and operations monitoring and reporting from Smart Link. Bombardier Aerospace is adopting the technology, which uses data links from the Aircraft Communications Addressing and Reporting System, or ACARS, to "provide customers with real-time insight and significantly improve the way they manage their maintenance activities."
A new kind of synthetic polymer that duplicates the healing process of human skin brings scientists a step closer to prostheses with durable sensors that can impart a sense of touch. This development by researchers at the Israel Institute of Technology has solved the key problem of delicacy in the flexible sensors needed for touch-sensitive prostheses by creating the potential for "e-skin" to heal its own cuts and scratches.
A 2,000-pound, fiberglass-reinforced concrete sculpture on the lawn at MIT reveals the secret behind one of the great architectural mysteries of the ages. The massive McKnelly Megalith, created by students in the Megalith Robotics class, can be moved with remarkable ease and shows how the famous Moai of Easter Island -- whole-body statues that weigh as much as 82 tons apiece -- may have been moved with simple human power and ropes when they were set in place around 1100 AD.
A nonthermal, energy-efficient way of pasteurizing milk may be a boon for developing countries where conventional pasteurization isn't cost effective. The method -- a finalist for the MIT Clean Energy Prize -- was developed by a Stanford University team. It uses pulsed electric field technology to electrically polarize bacteria in milk to rip its cells apart.
Smaller companies that can't afford access to major autonomous-vehicle testing facilities can try out driverless tech in The Driving Simulator and Vehicle Systems Lab run by Germany company fkaSV. The SimLab, located in San Jose, Calif., will allow anyone to rent time to test developing safety or efficiency technology.
Rapid technology developments have created demand for engineers in a number of newer niche markets, such as virtual and augmented reality, unmanned aerial vehicle development, biomedical technology, urban sustainability and alternative energy research. This means new opportunities for innovative, young engineers looking to advance their careers.
