RE: Mars Lander EMC problem?

Sen. McCain is on the committee that oversees NASA. He recently said that the basic problem is poor management. IMHOP he's right. lou At 02:41 PM 3/30/2000 -0500, you wrote: Tony, I don't think it was actually EMC. The report I saw on CNN said the legs opened with a jolt, fooling the sensors

To those wanting more info on NASA Mars failure report

Sorry, my original posting may have misled those who have asked for more info. The e-mail I was refering to is simply the press release and has little more technical info. However, I do now have a copy of the complete NASA report! It is in 5 separate PDF files each 400k-500k. This has LOTS of

Re: REQUEST FOR HELP WITH LOOP ANTENNA DESIGN

Here is the equation for transmitting loop design (from Army EMC Handbook DARCOM-P 706-410): H = NIa^2/{2(a^2 + r^2)^3/2, where N = number of turns, I = loop current, a = loop diameter in meters, r = distance along loop axis from center of loop, in meters. H is in Amps/meter. A discussion of

RE: EMC Directive revisions

Now I am really confused!! As I understand it the EMC Directive was never intended to INSTRUCT folks what tests to run or indeed what levels etc..to demonstrate compliance. Indeed one of the statements from the SLIM was the Directive per se was just fine and that the standards etc were the real

RE: Mars Lander EMC problem?

Tony, I don't think it was actually EMC. The report I saw on CNN said the legs opened with a jolt, fooling the sensors which were supposed to cut the retro rockets when they detected the shock of landing. Scott Lacey It looks like Scott Lacey is right, thank you! I made the assumption that

It concerns me that a device such as this would have its safety dependent on lubrication. One would expect that it may be infrequently serviced as a result of being in an attic. Additionally, thermal cutouts for these applications should be not be designed to allow them to be defeated.

Bellcore Standard for Alarms

Hello All, Does anyone know of a Bellcore/Telcordia standard that covers alarms in the CO?. If not, what are the rules covering alarms in the CO? What kind of relays are called for? (ie. N/O, N/C, both)? What current is the relay expected to handle? Are there any definitions of Critical,
