RE: Laser Safety Calculations
Hi Rich, Sounds reasonable. Actually, it sounds like a tool that a transciever vendor would offer on a webpage to assist their customers in development using that vendors' component... Has anyone come across such a thing ?

RE: Laser Safety Calculations
Chris, Try contacting Donald Drozdenko at HP (Aligent) at 408-435-5807. Don headed the testing / certification efforts for HP's Laser Led products back when 825 first emerged. Another person who may be able to help is Dr. Joseph Tajnai (408)435-6331, also from HP and member of TC76.

I myself have looked at the diagrams a few times and can't figure out what symbol is representing what angle ... I would love to see a few examples and more complete descriptions of the nomenclature. Is there a text out there, either commercial or from IEC that goes through these calculations in more detail?

Re: Sharp edge point
Bob, I agree with your statement about using it to settle arguments. That is why we bought it. The bloody fingers of several engineers were not convincing enough, so we had to resort to a tool of less subjectivity. It succeeded it getting the then prototype sheet metal in question run through a deburring process as a production function. Downplaying its' own inherent degree of subjectivity, for my money - it works as well as a gauge as it does as an argument ender, and I like having it in my tool arsenal. Stephen At 05:28 PM 10/16/00 Monday , Robert Johnson wrote: It's also available directly from UL. It is not very sensitive. It takes a very sharp edge to fail. It is not for testing points, only edges. I find it mainly of use to settle arguments. It also seems it would be rather variable if it came from several different manufacturers. After some experience, I would prefer to stick with the wording in the standards and leave it up to interpretation and judgement.

Screen Room Available
Universal Shielding Corp. USC-44 8'x8'x8' sheet metal over wood for the bottom half and the upper half is copper screen. The factory price is $7,200 plus one half shipping cost. We are asking $3,600 and will pay one half the shipping cost and one half the cost to crate the unassembled unit. A line filter and manual are included. The unassembled unit is located at Boulder, CO. Lowest cost crating is $200 and lowest cost shipping, for example, from Boulder to Long Island is $1,200 (shipping wt. 3,000 lbs). Your shipping cost in this example would be $700. For this example, your total cost would be $4,300. We will also consider the best offer. The USC-44 has attenuation of 40 dB at 15 kHz magnetic, 120 dB at 15 kHz electric, 100 dB at 100 MHz, 93 dB at 1 GHz, and 60 dB at microwave frequencies.

Product Safety Workshops Vemdors' Night
Hello all, In just a month, on the 15th of November, the largest (and best in the U.S.) electrical product safety workshops and show are scheduled to take place in Boxborough Massachusetts. The Northeast Product Safety Society, Inc., is sponsoring 27 Technical Sessions (11 A.M. to 5:45 P.M.) followed by their Sixth Annual Vendors' Show (50 Table-top exhibits, 5:30 P.M. to 9:30 P.M.). This is a major undertaking and is carried our as part of our educational offerings. The workshop and the exhibits both encompass electrical product safety and emc interests (among others). For full listings and Registration Forms for the Workshop2000 and/or the Vendors' Night, visit www.nepss.org where you will find all the necessary information. There is no charge for either event (there is a sandwich-buffet meal too, free to NPSS Members and 15.00 to others). Is this event worthy of the travel that some will have to undertake? We believe so (last year we had a visitor from the U.K.). If you would like to meet and network with your associates, test labs, suppliers of components and services to the trade, you ought to be there. We hope to see you there.
