Doug,
From an environmental, not compliance, standpoint, batteries leech nasty
chemicals into the groundwater supply as they age in landfills. Enlightened
communities sponsor 'hazardous waste roundups' periodically. So, my
suggestion is to keep the dead batteries in a sealed container in the home

Yes, There is a concern on the failure at least a single fault - but
I believe the IEC 825 requires a double fault protection, but others may
know more.
You would have to know what the faults of the micro are fail, on

I have a question on lasers for ITE concerning IEC-825 and FDA requirements.
According to IEC, class 3b lasers have to have safety doors (interlocks).
Can automatic power reduction be used if you are not pumping the laser to a
3b class level of power. In other words, can we not put interlocks

All Panasonic Lithium Ion batteries are classified by the federal

municipal waste stream.
Hi Ken:
In conclusion, dithering will help you meet a test requirement, but it might
not actually reduce potential interferences.
I have come to the same qualitative conclusion,
and the EMC experts with whom I have discussed
this concept agree.
But, is there any evidence, anecdotal,
Be careful. IBM (perhaps Lexmark now) holds a patent on certain aspects of
this technology.

Sandy,
While it doesn't apply to ITE, the 2nd edition of IEC 60601-1-2 (medical
electrical devices) does extend the upper frequency to 2.5 GHz, mostly in
response to the presence of cell phones in the hospital environment. This
document is at FDIS stage with final vote due 13 July.
Regards,
In my humble opinion:
The dither works really well since the time that the clock is on any one
frequency is small with respect to the receiver 120 kHz resolution
bandwidth, and you get a lot of averaging. However at around 200 MHz you
might not be in band to a radio broadcast, but rather a

I am looking for the status of a frequency extension to EN 6100-4-3

I am experiencing a EMI failure during testing and it has been isolated to

The Battery Act regulates disposal of NiCd and SSLA (Small Sealed Lead Acid)
batteries in the US, and mandates that manufacturers provide consumers with
a means of safe disposal. Canada has a similar act. I'm unsure of the
details in the EU, but I'm sure similar acts exist. There are two harmful
