Solar power discussions typically center on the solar cells, but the inverters are an equally important aspect of energy conversion. Fronius USA’s IS 30 stand-alone inverter accepts a nominal battery voltage of 24 or 48V and supplies a nominal output of 2,200 VA at a maximum efficiency of 93 percent. The inverter weighs only 18 lb, so it’s practical to connect them together in parallel or in multi-phase operation even in constrained home applications. One factor in its high efficiency is the control architecture managed by Microchip Technology Inc.’s dsPIC digital signal controllers. Fronius exploits the 30-MIPS chips, which include counter-based PWM modules and analog circuitry.
Inforbix is leveraging its CAD and product data access technology to power up a free iPad app that lets mobile users search and access engineering data.
Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
