More than a million times each year in hospitals all around the world, a device called the heart-lung machine keeps patients alive while surgeons repair damaged hearts in an unobstructed "dry environment." Those who benefit range from tiny babies with congenital defects to adults suffering from arterial blockage. For many years, Richard Griewski has led the design efforts on the 3M Sarns brand of heart-lung pumping systems, one of the oldest and most respected names in this life-sustaining technology. Griewski has played a particularly important role in pioneering the first computer-aided centralized monitoring systems for heart-lung machines. In the process, he has had to learn the fundamentals of cardiac surgery to address the human factors needs of the perfusionists who operate this equipment during critical moments. His engineering expertise also includes: pumping systems, cell biology, display systems, electronics, software, and electromagnetic compatibility. One veteran perfusionist at the famed Texas Heart Institute calls the Sarns devices the "Coca Cola" of the field, based on the machines' long track record for reliability, as well as such innovations as automatic battery backup, integrated gas mixer, and "splash-proof" design.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
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.
