RE: Define Continuous DC Voltage - defibrillation

For those who want to skip it, this is not product safety, just a digression from the electric shock topic. As for why the chest thumping works, take the heel of your hand and whack yourself on the side of the head. You'll notice the effect as quite a few cells depolarize. That's the general

RE: Methods Equipment; Surge Dips

To answer the below -- KT has had the equipment for about 10 years. For rental -- call Transient Specialists at 866-364-7368. For robustness -- need to know the load. Large in-rush currents are generally no problem. I agree about the Pacific Power units -- we evaluated them here some years ago --

RE: Methods Equipment; Surge Dips

True, but did KT have this equipment 4yrs ago? Does anyone you know of rent this equipment? We also have a Schaffner tap switcher, but it eats itself under heavy loads. Is the KT stuff more robust under heavy startup loads? The Pacific Power equipment I use has never broke down. Worth the

RE: Methods Equipment; Surge Dips

Seems to me this is the hard way to do it. KeyTek has a product that is a tap switcher for the required levels and will pass the in-rush currents required. It's a much smaller package. Also, other manufacturers have systems that are basically software controlled switches -- bring in the

Administrative message -- Decorum

Over the years, this listserver has never had a problem with decorum. We have had no rules addressing decorum. I and the other administrators do have expectations for decorum in posted messages. Here are our expectations. Decorum: -Propriety and good taste in conduct or appearance.

RE: Methods Equipment; Surge Dips

Hi William, I dont know about renting equipment for the tests. You can probably find it. For the -4-11 (dip/dropout) test; Depending on your load, your site wiring has to be up to snuff. The power sources for doing the dip and dropout test are hefty stuff. My lab uses a three-phase powered source

RE: Methods Equipment; Surge Dips

Hi all, John Crabb asked me about my previous response (see below). He brings up some points that I don't have experience with. I wasn't sure how to answer it. I was hoping that someone else could address his concern. For our AC powered equipment, we have never needed to add varistors,

RE: Define Continuous DC Voltage - defibrillation

Robert, Thanks for this very interesting piece of data. I've often wonder what atrioventricular fibrillation is, you provide some insight on that as well. If it is a reset of sorts then how did the thumping of the chest ever work? I suppose it can also fall into the category of just being

RE: Quality Assurance and product approvals

You are all making some excellent points. It would seem that many of us share commonality. Perhaps that is one of the underlying purposes of the quality organizations. When followed, the effects are positive and things move correctly, and in synch, but when exceptions are present... In my case,

RE: Define Continuous DC Voltage - defibrillation

I also have not encountered the theory about chest compression controlling fibrillation. Since defibrillation is also controlled during open heart surgery by paddles directly applied to the heart and through the use of wire catheters from implantable defibrillators, it is not the only means. I

EL (Electro Luminescent) considerations.

Hi Group, Could anyone tell me a little more about the safety implications/standards for the use of EL wire/sheet. Specifically when powered from a battery source,i.e. battery-inverter-EL, and the EL wire/sheet outer insulation is exposed. Thank you in advance, Enci

RE: Quality Assurance and product approvals

Morning Brian, et al. I don't have a large heartburn about the exact organizational chart location I have been in them all - well not actually sales I do have some standards* - and I find the debate very valuable! Location doesn't really create or fix all that many problems. You kind

RE: 80/80 rule for euro compliance?

Actually, Vilfredo Pareto (1848-1923) was an Italian economist. He observed that 80% of the economy was driven by 20% of the consumers, i.e. 20% of the customers account for 80% of the turnover. Two decades ago I was involved in an effort to create a data bank of IBM typewriter service

Hi Wm (my guess is William), Didn't see a response to your question. Got lots to do today, so I'll be quick and dirty. (Well I thought I would...as you can see it wasn't so quick but it is dirty :-) Test equipment... Surge Testing... There are quite a few companies that make equipment that

SV: Walkie-Talkie in Thailand

Hello KC Chan, In Thailand the bands 26.960 - 27.410 MHz, 77.9875 - 79 MHz and 244.9875 - 246 MHz are designated as Citizens Band (CB). The bands 79 - 79.9875 MHz and 246 - 247 MHz are reserved for similar purposes. You may download the Thai frequency allocation table from

I think the point raised by Gary re: where the Compliance group fits into the organisation structure is more important than procedures/process, although I disagree with him about where that should be. Let me explain. Having a good working relationship with Engineering is indeed critical, however

Re: Quality Assurance and product approvals

Hi Tania, I just finished writing a procedure on agency certifications for a client (prompted by their ISO 9000 audit). It became partly glossary partly encyclopedia so sales, marketing, etc could find definitions and explanations of what the agencies are and why we need the certifications.
