ELECTRONICS: Electronic components distributor Digi-Key Corp. is now stocking C&K Components’ ELUM Series switches. Designed to eliminate the need for separate LEDs and light pipes on printed circuit boards, these switches feature a 6 mm profile and are available in through-hole and surface-mount configurations. The ELUM features silver- or gold-plated contacts that range in ratings from 0.01 to 250mA and from 20mV to 50V dc. The latching version (push-push) can be specified for switching functions such as mode select and power on/off, while the momentary version is ideal for test, reset and notification functions. The ELUM Series device is one of the only push-button switches designed so the LED travels with the actuator, ensuring even distribution of light. The compact design saves space on the PC board, enabling product miniaturization and greater onboard functionality. ELUM Series switches are RoHS-compliant and compatible with high-speed reflow soldering processes. The 30,000-cycle life expectancy makes the push-button devices ideal for telecom, industrial, medical, automotive and consumer electronics applications.
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.
