RE: Don'r Get Caught Running a Red Traffic Light!

This thread has digressed quite a bit... Allow me to add to it! 3M makes something called the Opticom System. It is a traffic management device that really helps emergency vehicles make their way thru heavy traffic... Here's an article that summarizes it nicely:

RE: AC 97

The source may be differential, but common mode currents generally contribute much more to radiated emissions, especially with cables... It sounds like you have cable radiation (100MHz) as well as maybe slot radiation (600MHz)... Tell us more about your device's test setup... (i.e. chassis and

RE: Chamber Doors

Are you sure? Berylium Oxide (BeO) has a long-standing reputation for being toxic, but I've never heard of metalic berylium (Be) posing a problem. See the following for more details: http://www.atsdr.cdc.gov/tfacts4.html Paul Hare e: ph...@pirus.com Compliance Engineer w:

RE: Reliability recommended books

I second that recommendation. I also have the solutions for the exercises in chapters two through sixteen if anyone is interested. Email me directly and I'll forward them to you... Paul Hare e: ph...@pirus.com Compliance Engineer w: 978.206.9179 Pirus Networks f:

RE: EFT Failures..Update!

Alex, make sure you investigate whether or not energy is coupling to other cables of the EUT and causing problems. In other words, try to reduce the system (remove cables) and see if the EFT failures persist. If you can't remove a cable due to functionality, place ferrites on it instead (near

RE: FCC rule interpretation (add'l info)

Stuart, As a side note, I've seen an FCC application where the second harmonic of the device was measured and reported to be at the limit (i.e. 54 dBuV/m). Since the second harmonic was the closest to the limit, the transmitter's power had been increased to a point at which there was zero

RE: EN61558 60742

Brian, As of August 1, 2001, EN 60742:1995 should not be used for presumption of conformity to the LVD. EN61558-2-6:1997 supercedes it. The last date of mfr is unimportant. The date which the xfrmrs are placed on the market determines which standards to use in order to demonstrate

This is from the Panasonic Battery Disposal Guidelines webpage with respect to Lithium-ion battery disposal in the US: All Panasonic Lithium Ion batteries are classified by the federal government as non-hazardous waste and are safe for disposal in the normal municipal waste stream.

Detachable AC Cordset Selection for the EU

Hello group, I am in the process of specifying detachable AC cordsets for European distribution of my product. It uses an autoranging power supply (100-240VAC) and is rated for 12 A max with a C14 appliance coupler. I initially thought this would be a trivial task of matching plug and

Cable Harnesses and Product Safety (UL1950/CSA C22.2 no. 950)

I use an outside vendor to assemble various cable harnesses for my products. The vendor is recognized by UL and CSA and undergoes quarterly audits. I supply a drawing that specifies certain components (e.g. Connector X, Line Filter Y). However, I leave it up to them to use whatever UL/CSA
