AutoEMC Newsletter No.29: July 2011
we’re still alive, but barely kicking! It’s
been over a year since the last Newsletter, mainly due to other commitments and
loss of staff from both the AutoEMC Network and the industry itself.
In fact it has proven very difficult even to get this Newsletter out, but
we’re trying to bring things back on-track.
The website has also been updated, it looks the same but the content and
some links are updated and other obsolete ones removed.
If you spot any errors or missing items on the website please feed them
back by return to this Newsletter, but change the Subject line otherwise we’ll
think it is a returned Newsletter.
AutoEMC.net newsletter is a text only e-mail newsletter with hyperlinks to
stories or items of interest noted in brief within the following text. If you
have any items for inclusion or ideas on how to improve this service please send
them by return e-mail.

and EMC Conferences
IEEE EMC Symposia
must be that time of year again? If
you failed to get to Hawaii a few years back, Long Beach is possibly the next
best alternative. The annual IEEE
symposium, arguably the largest EMC event in the world (argued by EMV in Germany
I expect) is back again from 14th to 19th August.
Yes the hottest month of the year in the middle of the holiday season in
one of the most picturesque beach resorts in the US.
Let’s all congregate in a hotel then!
Annual EOS/ESD Symposium & Exhibits
you simply can’t get enough of the West Coast here’s another excuse to
visit, from 11th to 16th September 2011 at the Disneyland
Hotel, Anaheim, California, USA a very focussed event on ESD and related
a little more specialised that other events listed here, but to those in the
business possibly one of the more focussed events.
The focus here is definitely mobile phone antenna technology, so maybe
not high field strength test arena but still in the modern automobile this type
of antenna is going to be utilised more and more.
From 20th to 21st September in Nashville,
Tennessee, a place more familiar with country music lovers.
Chamber Theory / Experiment Short Course
23 September 2011, Oklahoma State University, Oklahoma, USA
16th Asia Pacific Automotive Engineering Conference (APAC 16)
be held for the first time in India from 6th to 8th
October 2011 at the Chennai Trade Centre, Chennai.
As one might expect, green issues will dominate, but no doubt there will
still be some content for the petrol heads in the crowds.
annual UK EMC conference and exhibition returns again to Newbury from 11th
to 12th October 2011.
for Papers: 2012 Asia-Pacific International Symposium on Electromagnetic
21st to 24th May 2012 in Singapore, call open until early
December for abstracts, October for tutorials and workshops.
for Papers: EMC Europe 2012
got until February next year, but if you’d like a September 2012 break in
Rome, get those abstracts in early.
Cars to Comply with EMC Standards from 2011
year saw the introduction of a national EMC standard for automotives in India.
This article in India Infoline explains the reasons but is a bit short n
which standards are being applied? The
country’s Automotive Industry Standards Committee (AISC) EMC standards
published in 2009 are derived from the usual ISO standards, but we have not been
able to obtain a copy to check the limit levels etc.
- IEEE Recommended Practice for Validation of Computational Electromagnetics
Computer Modeling and Simulations
not the catchiest of titles, but at last a standard for electromagnetic
modelling validation, something to give a bit of confidence in the results these
computer programmes kick out. In the
past it has been difficult to compare programs as their output was often very
different, hopefully this will start to improve consistency.
Effects of the New ESD Standard on ESD Simulators
could easily be forgiven for thinking the update to IEC 61000-4-2 Edition 2
might have no impact on your current test equipment, but have you really read
the detail in the standard, which becomes the mandatory version from next March?
FCC Launch New Website
old one looked OK to us, but the new one can be tested for the rest of 2011,
before going live in 2012, at the link below.
Acquires EMV GmbH
we know this happened some time ago (March to be precise) but we have only just
realised that this is a combination of 2 of our favourite companies in the EMC
equipment supply world. Is this a
one-off or is the AR train of consolidation in the test world starting to impact
Selection for Automotive EMC Emissions and Immunity Applications (100 kHz to 18
there are difference between the antenna used for standard commercial and
automotive tests, sometimes not always that obvious, but if nothing else the
differences in measurement distance can mean the need for different antenna
factors. This article by Dr. Vicente
Rodriguez gives more details on how to go about choosing the right antenna.
Uncertainty for Conducted and Radiated Emissions
oft-overlooked area, why do we often assume results as absolute?
An interesting article on this sometimes complex topic, but certainly one
that can be understood and better still constrained.
EMC Test System for Hybrid, Electric and Fuel Cell Drives
systems required to test these sorts of vehicles are already understood and can
be constructed today.
EMC Case Study: HMI Graphics Influence on Radiated Emissions
more graphics technology in the cock-pit of cars it is perhaps no surprise that
such a topic would surface. In-Compliance
covered this earlier this year based on last year’s IEEE Symposium, so if like
us your still catching up take a look.
Builds New Test Chamber
‘s Huntsville, Ala. operations have been
recently updated with the construction of a new drive-in environmental test
chamber designed to operate over a wide range of temperature and humidity
conditions. Types of test articles
that Wyle can support in the chamber include Humvees, satellites, automobiles,
energy equipment, bulldozers, missiles, and other military and commercial
Performance of a Product Over Its Lifetime
is an area that is often over-looked and rarely considered in most standards,
but should have a higher prominence. I
recall at an AutoEMC conference a paper by 3C Test Ltd some years ago on a
similar subject directly related to vehicles and after 10+ years the electrical
performance as well as EMC performance was certainly negatively impacted.
This Interference Technology article is definitely thought provoking.
Disguise AM/FM Radio in Spoiler
think GM would have enough EMC and radio experience to design their own antenna,
but apparently they used 2 radio ham’s for this?
Or are these radio ham’s also their antenna experts?
This article makes it sound like they went outside the company, but I bet
these guys are internal staffers, after all, you can be both radio ham and an
EMC expert, it’s how many in this industry got involved.
What this article does illustrate is how radio proliferation is starting
to impact vehicle and body design. As
radio content in the car increases this situation of multiple
receiver/transmitters is only going to get worse.
Working to Reduce EMI in Electric Cars
from Interference Technology on collaboration between Youngstown State
University and Delphi Automotive to examine the EMC implications of all electric
if that isn’t enough there is even an article about the EMC of electric cars
in the on-line Interference Technology guide;
Keynes, UK Installs Electric Vehicle Charging Posts
had to include this item from Interference Technology as its from “where we
live” and we know most of the people in the company that run this from our
past working life cross-over.
Inaugurates two New Sites in China
there are Automotive Design vacancies out there, especially if you live (or are
prepared to move to) China. Valeo is
the latest company to open 2 major design centres in the growing Chinese economy
to serve local production I guess.
Design Series On-Line
of Automotive Designline and EE Times, this series of articles provides one of
the best groundings in electronic design for EMC available for free.
Daryl Gerke has put together a series of articles covering the basics and
some of the critical areas that electronic designers need to consider when
designing to meet EMC requirements.
Tests Find No Toyota Flaw in Electronics
all the fuss over the Toyota accelerator issue?
No? Well there were a few in
the EMC industry keen to point a finger and try to blame the EMC testing and the
standards, despite a lack of evidence, but few came forward to apologise
afterwards. The AutoEMC website were
always keen to support the “innocent until proven guilty” position of the
electronics and this has proven to be the correct approach.
The item however soon falls from the news so if you missed the clearing
of the electronics as a culpable suspect here is the outcome from AutoWeek in
February of this year.
