MOTION CONTROL: MDrive® Linear Actuators provide linear motion in an extremely compact all-in-one package with leading integrated step motor and driver technology, available in three motor sizes and two shaft styles, with options including fully programmable controller and motion control technology to prevent unintentional stalling within the same small footprint. MDrive Linear Actuators are available in two shaft styles (non-captive and external) with a choice of three NEMA motor sizes (14, 17 and 23). These products have an input voltage range from +12 up to +75V dc, nominal load limits of up to 200 lb, and are capable of full (256 x 200) microstepping with an operating range of -40 to 85C for long life, trouble free service in demanding environments. Linear actuator screws are manufactured from premium grade stainless steel, corrosion resistant and non-magnetic, and are available with an optional Teflon coating. These precision rolled screws are offered with many lead pitches and end finishes, and can be ordered in 0.1 inch length increments to meet a wide range of application requirements.
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.
