SENSORS: TURCK’s Q25L sensor is a magnetically actuated linear displacement sensor designed to detect piston position on pneumatic cylinders. Available with measuring ranges of 100, 125, 160 and 200 mm, the Q25L is well-suited for applications that require precise signal transmission over long measuring distances, such as pneumatic pumps, slides, blanking or molding systems. By utilizing an external magnet as a position indicator, the sensor may be used in additional applications such as moving platforms, point line measurement or other specially designed equipment where a cylinder is not present. Like TURCK’s other cylinder position sensors, the Q25L detects the position of a piston on standard pneumatic cylinders by utilizing a series of Hall elements that sense the piston magnet and send a signal back to the processor. The Q25L has a repeat accuracy of less than 0.1 percent of the measuring range and a linear deviation of less than 1 percent of the full scale. It also features a blind zone of only 20.5 mm on each end, making it easy to apply in space-restricted areas.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
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.
