Neurostimulators improve quality of life 4/23/2009
Chronic-pain sufferers can benefit from a rechargeable spinal-cord stimulator from the St Jude Medical Neuromodulation Division.Metallic spring sensors serve as rugged, reliable capacitive sensors 3/13/2009
"White goods" often cannot accommodate a pc board directly under a surface as required by a solid conductive sensor. For these applications, consider a metallic spring sensor.A bad-capacitor story ends happily 1/8/2009
Tales From The Cube: When the same capacitor ends up charred in too many systems to dismiss the failures as statistically possible, an engineer must approach the problem via old-fashioned layout inspection.The Hot 100 Electronic Products of 2008 12/15/2008
EDN's editors offer up their annual list of the year's 100 most significant ICs, components, buses, boards, EDA tools, power devices, test instruments, and more.Compact fluorescent lights: Not always the best solution 10/30/2008
Prying Eyes: A look inside a CFL bulb helps explain why they're no good in downward-facing installations.Optimize memory-system design for multimedia applications 9/4/2008
The convergence of video and communications in inexpensive unified-memory architectures has made DRAM the most important and the highest-performance target in any system.The case of the stolen capacitor 9/4/2008
Tales From The Cube: An engineering change order erases a design's input stabilizing capacitance, with costly results.ESR calculations for electrolytic capacitors at lower temperatures 8/20/2008
Use this empirically derived formula—and online calculator—to determine ESR at the low end of the temperature range.Determining end-of-life, ESR, and lifetime calculations for electrolytic capacitors at higher temperatures 8/20/2008
