ELECTRONICS:Dytran Instruments’ new miniature triaxial accelerometer is designed for modal analysis testing. The 3273AT series features a robust, laser-welded titanium design, which includes ceramic sensing elements coupled to ultra-low-noise JFET electronics. It includes IEEE 1451.4 TEDS. With a low end frequency response of -10 percent down to 0.31 Hz, the 3273AT series accelerometer offers excellent phase response at low frequencies. It also features an excellent signal to noise ratio. The 3273AT series accelerometers are available in sensitivities of 10, 50 and 100 mV/g. Featuring a hermetic seal, adhesive mount and a single four-pin connector, this triaxial IEPE accelerometer weighs only 2.7 gm. Its titanium housing contributes to its light weight, which provides for minimal mass loading of the accelerometer on the test article.
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.
