Commercial EMI Standards vs. MIL-STD-461 … Now What?
I seem to hear a never ending litany of complaints about how the US military acquisition community has to use more and more commercial equipment (COTS or CI) and that said equipment tends to be highly problematic from an EMC perspective. I tend to dwell on this subject in this blog space, hopefully from different angles, but at the end of the day, I don’t see much being done … [Read more...]
Planes Need to be Grounded to Something?
Editor’s note: This question was asked in response to Interference Technology’s recent webinar by Keith Armstrong. To view the webinar, click here. Question: Planes need to be grounded to something? Answer: It depends on what is meant by the word “grounded,” because there is an awful lot of general confusion associated with issues of grounding/earthing. As my slides said, … [Read more...]
How Does a Chassis Carry CM Noise?
Editor’s note: This question was asked in response to Interference Technology’s recent webinar by Keith Armstrong. To view the webinar, click here. Question: How does a chassis carry CM noise ? Answer: A chassis is just a piece of metal—a conductor—so it can carry CM noise currents just like any conductor can. The reply to question 1 might help. -Keith Armstrong … [Read more...]
Wireless Signals Track Hidden Moving Objects
A new technology developed by researchers at MIT’s Computer Science and Artificial Intelligence Laboratory could give users the ability to track hidden moving objects using wireless signals in handheld form. The technology—known as Wi-Vi—transmits a low-power Wi-Fi signal and uses its reflections to track moving objects, such as a human body, within a closed room or behind a … [Read more...]
