News reports drone on constantly these days with more and more negative information. I don’t get the same kind of vibe when I talk to design engineers every day for my writing about materials and fastening technology for Design News. Most incredible to me are reports on advances in medical technology by American inventors and engineers. The most recent was an interview I had with Dave Danitz, the vice president of research and development at Novare Surgical Systems In California, which recently developed and brought to market an instrument called RealHand that allows laparoscopic surgery through a single port—and even through natural orifice such as a mouth. The result is a dramatic reduction in the risk of infection.
Invented by Danitz, the RealHand is a fully mechanical instrument up to 45 centimeters in length in which jaws at the distal end move inside the human body in reaction to movements of a surgeon’s hands on a handle. Small articulating links connect the jaws to the shaft and the handle to the shaft, which can vary in length from 24 to 45 centimeters. There are no electronics in the device.
Although introduced just six months ago, a number approaching 100 surgeons use the tool.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
Some in the US have welcomed 3D printing for boosting local economies and bringing some offshored manufacturing back onshore. Meanwhile, China is wielding its power of numbers, and its very different relationships between government, education, and industry, to kickstart a homegrown industry.
You can find out practically everything you need to know about engineering plastics as alternatives to other materials at the 2014 IAPD Plastics Expo. Admission is free for engineers, designers, specifiers, and OEMs, as well as students and faculty.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
