Designers of machinery powered or controlled by hydraulics or pneumatics need to keep an eye on ISO's technical committee on fluid power. Called ISO/TC 131, the committee has been revamping several global guidelines. It has issued draft standards that specify dimensions for five-port, pneumatic-valve interfaces that are smaller than those currently standardized. ISO/TC 131 also is studying the performance of hydraulic filter elements, hoping to develop standards that will allow better choices of filters and closer monitoring of contamination in hydraulic systems. Under revision, too, are general rules for industrial fluid systems. A subcommittee is attempting to blend in European safety rules. In addition, the committee is updating the standard vocabulary for fluid power, adding definitions and terms in German. Comments Karen Boehme, secretary for ISO/TC 131: "The resulting international standards will make it easier to design, run, and maintain safer, more efficient hydraulic and pneumatic systems."
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
