RE: EMC-PSTC on a web site
Rich and I have been quietly working on the Mindcruiser site. It has bugs which we are still working out and has prevented us from making it a live site. However, if you have ever posted an e-mail to the majordomo list it has automatically created an account for you and put the message into the archive. We have a lot of account clean up to do. Mindcruiser will send you your password if you ask it to. It is case sensitive, so when it asks your account name and e-mail address you have to get it right. If you need help getting access to your account let me know and I will assist ( be patient as this is an after hours volunteer work ). You can browse it as a guest for the moment. The e-mail archives are on the site and are active, in that if you respond to a forum in the Mindcruiser archive, it will go to everyone on the majordomo emc-pstc list. If you send an e-mail to emc-pstc on majordomo, it also goes in the archive on Mindcruiser (it is the second e-mail address on the IEEE server, so it gets there fast). It is a bi-directional link between the servers. Note: We are still looking for e-mail archives prior to 1996, if you have them let Rich or I know you have them. We will be looking for a few people to start using Mindcruiser rather than majordomo in the near future (April?). Some of the error messages you are seeing at the moment are do to a bug in the software and will be fixed shortly. I expect the next release of software to fix most of the issues we have at the moment and make it possible to go live with the site. If you are one who just monitors the messages, Mindcruiser will allow you to get a daily or weekly summary rather than the constant inflow of e-mail.. Note: because of the archiving of the messages, it is important to always use text and strip out the footer when you respond to a message through majordomo. That will help keep the database cleaner. The IEEE is working on populating the infopieces. If you run into any bugs while on the site please report them to Mindcruiser as well as Rich and myself. Also let us know of any suggestions for the site. Jim Jim Bacher, Senior Engineer Paxar Corp.

RE: Pencil erasers for pre-EMI cleaning? (cleaning mating surface s, chassis, )
Robert, The North American paper sizes are not irrational, just dated. The engineering sizes (A through D) were originally mainly used with the contact diazo (blueprint) duplicating method. The copies are all at 1:1 ratio with the original drawing, which was hand drawn in the days before CAD. Enlarging/reducing had to be done with a very large and expensive process camera. This was usually only done to make offset printing plates for manuals. The selection of sizes was actually very rational, as all the larger sizes can be neatly folded to A size (8 1/2 X 11) with the title block showing on top. As for the U.S. Patent Office, I believe the switch to the metric paper was done at the same time the patent period was changed (along with other details) to harmonize with other nations under international patent agreements. Finally, the side issue of discussing paper sizes resulted after it was mentioned that the downloaded galvanic compatibility chart could not be printed on 8 1/2 X 11 paper. If the host based printer driver is loaded it is possible to scale printed output to any size desired. The hardware based print drivers generally do not have this ability.

RE: Laser Safety
While it is technically possible to have a Class IIIb-capable component laser in a Class I 'system' the path there is not clear cut. Besides the emitter's technical issues (AEL, exposure time, radiant power, wavelength, to name only a few) you have to take in consideration the failure modes of the laser driver circuitry - that Class I limits can be exceeded in event of failure, whether the system is a closed system (beam accessibility during service/normal use), the products installation location and acessbility to unauthorized personnel etc. Your best bet in classifying your 'system' is to look at ANSI Z136.1 and .2 specs. In my opinion (some may disagree) it's a good guide.

RE: CE marking of equipment for military facilities
Alexandru Friends Been there, done that (many times!): LVD: - No exemptions in Directive, or none found in any national legislation. EMC Directive: - No Exemption in Directive, but most EU countries (Not Holland and a couple of others) have implemented exemptions in national legislation under Article 226 (was 221) of the Treaty of Rome). In UK this exemption is not automatic, but is stated to be at the iscretion of tne Secretary of State for Defence. Nevertheless we do not have any trouble with our UK MoD Customers when we just claim exemption on the basis that we will meet the equivalent DEF 59-41 EMC standards. Other countries may or may not accept the same approach Machinery Directive: - Article 1 paragraph 3 includes the following exemption - machines specially designed and constructed for military or police purposes. All national legislation is assumed to include the same exemption. (Note: RTTE Directive has a similar, but differently worded, exemption in Article 1, paragraph 5) However, watch out for: a) Equipment which is not exclusively for military use, which is then termed to be dual use - in which case it must meet the requirements for commercial sales, regards of whether it is sold to the commercial or military markets. This means that your commercial equipment must meet the CE requirements. b) Military customers who want the CE Marking regardless of the letter of the law.

Re: CE marking of equipment for military facilities
During my final active duty tour, with the US Army in Germany, we deployed Korean-War-vintage, manual telephone switchboards for less critical telephone circuits. That was OK as long as we kept them on US bases and connected them only to US lines, but as soon as we connected them to Bundespost leased circuit, we had to pay a daily fine of (I believe) some hundreds of Marks, because the equipment was not VDE-approved.

R: CE marking of equipment for military facilities
An answer for you is in the document Guide to the implementation of directives based on the new approach an the global approach. The document is available on the Internet and can be downloaded from the Europa server at the following address: http://europa.eu.int/comm/enterprise/newapproach/newapproach.htm At page 15 you can read: Products specially or exclusively intended for military or police purposes are explicitly excluded from the scope of certain New Approach directives. For the other directives, Member States may, under certain conditions, exclude from their field of application according to Article 296 of the EC Treaty, products intended specifically for military purposes. In your case (normal circumstances, not exclusively military) I think you have to CE mark your equipment. L.

RE: ESD Generator confidence test (humor)
My first memorable experience with ESD was at the age of 10. I would build quite a charge on my body when playing basketball in the gym. And I would always get a hugh zap when I pushed on the metal handle of the water fountain. I knew just enough physics to know that a rubber basketball was an insulator so the next time I went to get a drink I used the basketball to push on the handle and then bent over to get a drink.well you know the rest. I still carry a tiny scar on my lower lip to this day.

Is there any useful information to be gained from the slight quiver, i.e. frequency, amplitude etc which might help with calibration of the discharge tip? Should the stop-watch be calibrated or would any wrist watch do, including the lab assistant's own? Has any such confidence test resulted in immediate vacancies in the engineering department, specifically, for a lab assistant. Can we extend this principal to confidence tests on surge equipment using middle management and members of the sales departments?
