ELECTRONICS: Equipped with capabilities found in more expensive instruments of this type, the new 0.1 percent Accuracy, Bench Model, LCR Meter from Protek Test and Measurement features RS 232 and Handler interfaces. For its $992 price tag, the Model Z8900 offers six measurement modes including C+R, C+D, L+R, L+Q, R+Q or Z+È at test frequencies of 100 Hz, 120 Hz, 1 KHz or 10 KHz, with drive voltages of 0.1V, 0.3V, or 1.0V and measurements rates to 12 per second. It incorporates a built-in comparator for sorting components according to value and tolerance, a RS232 interface for Remote operation and a Parts Handler Interface for operating your component sorting equipment. Add to these, a large five-digit dual LCD for displaying parameter values in Absolute, Delta and Delta %, Automatic or Manual triggering; and short and open circuit calibration for increasing measurement accuracy. Accessories include: operating manual, test leads with Kelvin clips; radial lead test fixture with axial lead adaptor; shorting bar; and AC line cord. The Z8900 requires 220V or 120, 50/60 Hz ac power, switch selectable and operates in temperatures from 0 to 40C (32 to 104F).

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.
