MATERIALS: The small spring applied brake series from Ogura (models MCNB 2, 5, and 10) have been redesigned and will now have a thinner profile. The brakes overall reduction in thickness is around 30 percent. Advances in friction material have allowed the brakes to maintain their same torque rating while eliminating the need for higher force springs and a correspondently higher wattage coil. The new thinner spring applied holding brakes are ideal for the servo motor and robotics industries where size and weight is always a concern. Since less steel is used in the coil shell and less copper in the windings, cost of the brakes are also lower than the current MCNB series. On some of the models, the outside diameter has been slightly reduced but all of the models have the same through whole mounting dimensions as the current MCNB brakes, so brake models will be interchangeable.
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.
