CISPR 14-1:2005+A1:2008+A2:2011 applies to the conduction and the radiation of radio-frequency disturbances from appliances whose main functions are performed by motors and switching or regulating devices, unless the R.F. energy is intentionally generated or intended for illumination. It includes such equipment as: - household electrical appliances, - electric tools, - … [Read more...]
Automotive RF Immunity Test Set-up Analysis: Why Test Results Can’t Compare
Mart Coenen, EMCMCC bv, Eindhoven, the Netherlands Hugo Pues, Melexis NV, Tessenderlo, Belgium Thierry Bousquet, Continental, Toulouse, France ABSTRACT Though the automotive RF emission and RF immunity requirements are highly justifiable, the application of those requirements in an non-intended manner leads to false conclusions and unnecessary redesigns for the electronics … [Read more...]

Discovery Channel’s MythBusters Discuss In-Flight Cell Phone Interference
Discovery Channel's MythBusters have taken on more than 700 myths, from how hard it is to find a needle in a haystack (it's hard) to whether toothbrushes have fecal matter on them (they do). In a recent NPR interview, series hosts Jamie Hyneman and Adam Savage talked about the show, including myths about cell phones interfering with airplanes.Listen to the show.Learn more from … [Read more...]
Scientists Create Light from Vacuum
Scientists at Chalmers University of Technology have succeeded in creating light from vacuum – observing an effect first predicted over 40 years ago. Chalmers scientist, Christopher Wilson and his co-workers have succeeded in getting photons to leave their virtual state and become real photons, i.e. measurable light. The physicist Moore predicted way back in 1970 that this … [Read more...]
Navy's Electromagnetic Railgun Reaches Testing Milestone
The U.S. Naval Research Laboratory Materials Testing Facility demonstrated, Oct.31, the one-thousandth successful firing of its Electromagnetic Railgun, reaching a materials testing milestone in the weapon's technological development and future implementation aboard U.S. Navy warships.Without the need for dangerous explosives storage and handling, the Electromagnetic Railgun … [Read more...]

DC-DC Converter Targeted at Solid State Drives
Enpirion’s new member of its power IC portfolio is targeted at solid-state drives (SSDs) as well as industrial embedded applications. The Enpirion EN5339 3 Amp power system-on-a-chip (PowerSoC) integrates the controller, power MOSFETs, compensation network and inductor into one compact solution that reduces the traditional engineering analysis and design effort associated with … [Read more...]
Expand Safe I/O with Modular Safety Controller
Phoenix Contact’s new modular safety controller makes it easy to expand I/O in a safety circuit. The PSR-TRISAFE/M (for modular) connects up to 10 safe digital I/O modules, thanks to a T-bus system. The TRISAFE/M’s base station has 20 safety input signals and four safety category 4 outputs. It also provides outputs for a test pulse, alarm (aux), and ground switching. The safe … [Read more...]
