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."
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
Green energy is being billed as a way to make communities that are energy deprived more self-sustaining. So it makes sense to use natural materials to create devices that harvest this type of energy. That’s the idea behind a hybrid wind/solar energy harvester made of bamboo that’s been developed by UVM researchers.
Anyone who’s ever moved files from a hard drive to a computer has sat patiently waiting for the transfer to complete. But what if this process could be done wirelessly, without having to connect devices with cables, and in seconds?
