Trang 10PowerPoint can kill
To most engineers, the idea of using graphs or models to convey concepts comes as second nature In many cases, these representations get shared through a PowerPoint presentation You might think that a presentation tool like PowerPoint couldn’t get you into much hot water — at worst, it might inflict acute boredom on colleagues But taking PowerPoint lightly
is particularly dangerous for engineers
So warns Franck Frommer, who recently wrote a book (How
Power-Point Makes You Stupid) about PowerPower-Point’s downside For instance, take
the idea of expressing concepts in a PowerPoint chart “Diagrams kill thought!” cautions one business veteran She explains that drawings are okay for detailing processes, circuits, and other well-defined relation-ships But they are a terrible way of expressing anything dynamic such as
a strategy Her point was diagrams are prone to lull viewers into accepting
a static and oversimplified outlook on problems that are inherently bile and changing
mo-Bad PowerPoint even played a role in the Columbia Shuttle disaster After Columbia broke up reentering the atmosphere in 2003, a series of NASA-prepared slides about the shuttle came under intense scrutiny All these slides were prepared using PowerPoint Data-visualization pioneer Edward Tufte took issue with one in particular that, he said, portrayed
a “festival of bureaucratic hyperrationalism.” Among the problems he noted was that the author had used six different levels of text to arrange and classify 11 phrases The primary information in the slide got rel-egated to small print several layers down
What is troubling about the NASA example is that PowerPoint itself encourages such problems through its built-in templates The software imposes what Tufte calls a summary style that can be confusing and lets users prepare slides using letter fonts that are inappropriate for the sub-ject at hand In the case of the Columbia slide, for example, the author had used a “pitch-style typography” that tended to belie the seriousness of foam damaging the heat shield
Organizations also have a tendency to let PowerPoint slide decks stitute for more-detailed forms of technical communication Frommer points out that the board investigating Columbia criticized NASA on this point as well, saying that the use of PowerPoint briefing slides instead of technical papers illustrated problematic methods of technical communi-cation at the Agency
sub-Many of the problems arising from PowerPoint come from the misuse
of bullet points, especially because this practice leaves out the logical connections that give the points meaning in the first place Worse, bullet points can be a screen hiding a “certain intellectual laziness” on the part
of users who never bothered to think out the connections, says Frommer.There are, in fact, a few individuals who have mastered PowerPoint One in particular was Apple’s late great Steve Jobs, Frommer claims You’d never see cornball images, poorly formed ideas, or a font festival
in a Jobs slide deck His slides were always simple, contained a organized argument, and used analogies to make numbers in the presen-tation memorable
well-But then again, there was only one Steve Jobs

Trang 14a sustainability standard (“Do We Need a Sustainability Standard?”
March 22) You can bet that this
is another way of making money
by the “standards” freaks and a way for the government to put more cost burdens on manufac-turing It’s also just more buzz-words to fill the law books by the environment crowd
The government will see this
as a way to force employers to hire more people to shuffle the sustainability paperwork Larger companies will feel forced to spend millions on this stuff be-
c a u s e t h e y s e e k g ove r n m ent contracts, and the costs of the standard will be passed on to the customer, the American taxpay-ers And smaller companies will
be forced to divert resources from innovation and breakthroughs to more nonproductive paperwork
As usual, American citizens will
be the ones paying for this useless stuff
Thanks for your comments It will be interesting to see if other business people have the courage
to speak against this hare-brained idea of another standard

We can fix for the
patent office
The U. S patent system is suffering
from two basic problems It is
be-sieged by submittals that are
funda-mentally flawed, but inventors are
encouraged to patent them based
on exaggerated promises from their
patent lawyers And second, the
Patent Office employs technically
weak staff that is overwhelmed by
the sheer number of patent
applica-tion But we can fix this
From 1977 to 2000, I was
in-volved in an effort to evaluate
concepts submitted to the
Na-tional Institute of Technology It
was funded by the Energy Dept
and was eventually called the
Of-fice of Technology Innovations
Ideas were analyzed and
evalu-ated by experts in the invention’s
subject matter, and not all ideas
revolved around energy
genera-tion or conversions There was no
charge to inventors for this service,
and promising entries went on to
further investigation in a second
phase If they survived the second
round, inventors could receive up
to $200,000 to develop working
proof-of-concept models
I worked at NIST in this Office
and analyzed about 750 concepts
over a 12-year period About 5%
of them involved patents The vast
majority of the concepts were
dis-missed at first glance because they
were obviously impractical or
fun-damentally incorrect The rest got
closer scrutiny, but few went on to
the second stage of evaluations
I believe that reestablishing this
Office of Technology Innovations
and broadening its scope to cover
all newly received patent
applica-tions would save inventors
consid-erable effort and money, as well
as taking pressure off the patent
office Of course, the patent
of-fice would also have to hire more
knowledgeable staffers as well

Op-Sats, here shown in
an artist’s conception, are simple spacecraft designed solely to test software They will have a volume of about
3 liters but will carry the-shelf components such as three-axis attitude-control systems, deployable fixed-solar arrays, GPS receivers, and UHF- communication systems
off-It will also have of-the-art components such as S-band communications with an uplink rate four times greater than any other ESA spacecraft and a miniaturized X-band transmitter providing up to 50 Mbps downlink These rates are up
state-to several hundreds times better than any other satellite flown
before
Eventually ordinary earthlings may be able to access spacecraft from a browser screen.
U. S citizens tend to think of NASA when
the topic turns to space exploration But the
European Space Agency (ESA), established
in 1975 to combine the efforts of 19 European
nations, has its own ideas for advancing space
technology Among the most interesting efforts
with which ESA is involved is one aimed at
extending Internet connections to spacecraft
Though its annual budget is about $5.2 billion
compared to NASA’s $18 billion, ESA is making
important strides in fundamental space research
Nanosats to test software
Engineers and technicians at ESA today control
satel-lites and space experiments using Packet Utilisation
Stan-dards, a software suite that dates to 1994 There have been
upgrades since then, but the stumbling block to moving
to newer software is that space scientists and the
organi-zations that fund them must ensure the software,
includ-ing operatinclud-ing systems, languages, and interfaces, is fit for
space
“No one wants to use new and possibly problematic
software on a multimillion-euro mission in space,” says
Mario Merri, head of the Mission Data Systems Div at
ESA operations center
Unfortunately, the only real way to prove software is fit
is to take it into space and run it through its paces
To lower the cost of validating software, and to
en-sure no missions are endangered, ESA researchers
devel-oped Operations Satellites, dubbed Op-Sats The 30 × 10
× 10-cm satellites’ mission is to test and validate critical
onboard and ground software The spacecraft is outfitted
with off-the-shelf processors that have more computing
power than a satellite usually carries It’s also designed
to recover easily and quickly from “buggy” software
Re-searchers on Earth can replace the entire onboard software
suite with new and fresh code daily, letting developers
troubleshoot their work in a real, but safe, environment
The first Op-Sats could launch next year
Spinning an interplanetary Web
People increasingly take reliable and fast Internet
ac-cess for granted Now space scientists want to extend the
same simplicity and reliability of the Web to astronauts on
the Moon or Mars The first goal will be to let astronauts
communicate among themselves, with control centers on
Earth, and with spaceships and bases But who knows; someday top-level Internet domains may include such names as moon, mars, or sstation
To this end, ESA, NASA, and other major space ganizations and industrial partners have been working together as part of the Consultative Committee for Space Data Systems They have developed standards for hard-ware and data exchange that should pay off even in the short term for commercial space-flight businesses, satellite manufacturers, and space agencies
or-Satellites have already been used for links between Earth and mission spacecraft In 2008, for example, ESA’s Mars Express acted as a data-relay node between NASA technicians on Earth and their Phoenix Lander during de-cent and landing on Mars, It will repeat that task in August this year with NASA’s Mars Science Laboratory
And last December, ESA’s worldwide tracking station network handled contact between Russian controllers and that country’s Phobos-Grunt mission to Mars Then,
in October of this year, an astronaut on the International Space Station will practice at remotely controlling a plan-etary rover at ESA’s operations center, simulating orbiter-rover communication links on a planet like Mars
“Establishing technical standards and tion architectures isn’t the most high-profile part of space exploration, but it’s absolutely vital for ensuring that the more-exciting efforts, like sending an astronaut to Mars, will work when that time comes,” says Nestor Peccia, the

launched into space
atop an Ariane 5 rocket
and then return to
Earth on it own, much
like the Space Shuttle The sensor had to be light and thin
so it would not add bulk or drag to the airfoil The
engi-neer turned to piezoelectric foil to do the job Like other
piezo materials, the thin foil (30-microns thick) converts
vibrations and pressures into electrical pulses that can be
measured and interpreted
The foil sensors were successfully tested in a
hyper-sonic wind tunnel, but the Hermes project was cancelled
So over the years, ESA has been looking for civilian uses
for the piezo sensors One of the earlier applications was
converting the foil to paint and putting it on a human
mo-lar Scientists used this ”instrumented” tooth to measure
forces a toothbrush puts on teeth
But just recently, Volkswagen saw the sensor
demon-strated at the Hannover Fair at a booth set up by ESA’s
Technology Transfer Programme Office They quickly
de-cided to use the piezo sensors on crash-test vehicles
Tradi-tional sensors do well at recording pressure up to the point
of impact, then they are too often destroyed in the crash

Catching a comet
Eight years ago, the Rosetta probe was launched on an 11-year convoluted
journey to chase down the comet 67P⁄Churyumov-Gerasimenko The
space-craft has already made three swingbys of Earth and one of Mars, and managed
to fly by a pair of asteroids, 2,867 Steins, and 21 Lutetia, and circle the sun four
times Currently, it’s traveling at about 2,600 fps and is on schedule for a May
2014 rendezvous with Comet 67P
Rosetta weighs in at 6,750 lb, but carries 3,200 lb of fuel It measures 9 × 7 ×
6 ft, but the twin solar panels deployed once Rosetta was in space give the space
probe a 104-ft “wingspan.”

aster-oids and Mars during the trip, but for the most part, it is hibernating, with

control, radio receivers, and
computers
Several challenges have
made it difficult for ESA
controllers to keep Rosetta
on track and healthy For
example, at some points in
its journey, it has taken 100
min for signals to travel to
Rosetta and for receivers to
get a response And
com-munications have been constrained by an 8-bps rate for
data and relatively little power available, compared to
other satellites This is the first solar-powered spacecraft
to fly farther than 3.1 astronomical units (288.3 million
miles) from the sun
Eventually, Rosetta must brake to match its speed to
the comet’s as they both head toward the sun Once within
a few miles of the comet, Rosetta will begin observing it
with its onboard instruments They include a UV
spec-trometer, ion-mass analyzer, impact analyzer and
accumu-lator, and an imaging system These last three are designed
to examine cometary dust
Once established in orbit above the moving comet,
Rosetta will release Philae, a 220-lb lander, and it will
be-come the first spacecraft ever to make a soft landing on a
comet It is made mostly of carbon fiber with a hood of
solar cells
While Philae and its suite of 10 instruments
investi-gates the comet from ground level, Rosetta will orbit and
study it for a year as it continues to its perihelion or
clos-est approach to the sun Rosetta will then remain with the
comet for another six months as the comet heads towards
the orbit of Jupiter, ending its mission in December 2015

runs at high efficiencies and current densities, several factors higher than standard LEDs that are fabricated on foreign materials,” says Krames “We get many more lumens per wafer This brings dramatic benefits in low-ering overall LED cost and in higher brightness.”Soraa’s first product to use GaN substrates is an LED replacement for a 50-W halogen that only consumes
12 W A point to note is that the lamp uses only passive cooling “Other companies that are doing this have
to use tricks like fans to cool the LED and get enough power,” says Krames “Our lamps also use just a single LED rather than an LED array found in competing de-vices This lets them produce a single clean beam with
a single shadow rather than a multishadowed beam which some consumers dislike,” Krames says MD
The surest way to make light-emitting
diodes that are efficient and bright
is to fabricate them on a substrate
made of the same material as the
LED itself
So says LED maker Soraa Inc.
in Fremont, Calif The company
produces LEDs that it claims emit
more light per unit area than any
other LED and handle more electric
current per area than any other
LED Soraa gets this kind of
perfor-mance by building the LEDs on a
substrate consisting of GaN This
dif-fers from the usual practice of
build-ing LEDs on top of either sapphire or
SiC, materials that are cheaper than
GaN and which are compatible with
it The problem with these substrates is that they can
induce imperfections in the LEDs grown on top and
these imperfections reduce the amount of light the
LED can generate
“Because we use a GaN substrate, we don’t have
such issues as wafer strain, wafer bowing because of
the strain, and (crystal) dislocation densities that arise
because of different substrates,” says Soraa CTO Mike
Krames “That allows a higher-quality crystal material
which leads to higher-performing devices.”
The LEDs made this way also are more efficient

native substrate to create an active layer stack that

Super concrete shielding Iranian nukes?
Some of the world’s experts in ultrahigh-performance concrete (UHPC) are working in Iran, a country regularly beset by earthquakes They want
to use the material, a mix of Portland cement, silica fume, quartz flour, fine silica sand, and either steel or plastic-reinforcing fibers, to build durable bridges, sewer pipes, dams, and other structures
But U. S military officials and others around the world are worried the Iranians will use the high-strength material to protect nuclear-weapons labs and to build other military bases and underground bunkers
UHPC’s compression strength is on the order of 30,000 psi, while that
of normal concrete is just 4,000 psi And UHPC has a tensile strength of 1,000 psi, far above normal concrete’s 400 psi Strength is critical for de-fensive structures Tests of a 13-ton bunker-busting bomb, for example, showed it could penetrate 180 ft of ordinary concrete, but only get through 25 ft of concrete that was twice as strong So it’s possible that the same bomb might only dent UHPC, with its compressive strength seven times that of normal concrete
So why isn’t UHPC more widely used?
If UHPC is so great, why isn’t everybody using it to build roads and bridges that could last 75 to 100 years with minimal maintenance? The
Federal Highway Administration points to five factors:
1 Contractors are slow to change currently approved practices and adopt new ones until they are sure of the safety and benefits of the new approach
2 Highway and infrastructure owners, usually the government, are even less likely to adopt new, potentially risky technologies, especially those that add costs
3 The dearth of design codes covering UHPC adds to the risks And contractors don’t want to conduct tests to prove a technology will work
4 Not many projects using UHPC have been completed and the material lacks a long track record This means there’s limited experience with inspecting, maintaining, and repairing it In fact, new methods for inspecting UHPC will need to be developed before its widely used

Ultrahigh performance concrete (UHPC) was used to make these thin, curved canopies over a train station in Calgary, Canada The 24 canopies are only 0.8-in
thick, so the project used only 105 yd 3
of UHPC.
UHPC also resists chemicals such as salt at rates 100 times greater than
that of normal concrete And the steel or polymer fibers add ductility and
strength For example, when microcracks start in the brittle cement matrix,
the fibers take up the load and prevent further slipping and cracking In
normal cement, the small cracks grow larger and weaken the structure The
fibers can also totally replace traditional rebar used to reinforce concrete
Silica fume, or ultrafine silica powder, also adds several benefits to
UHPC On a chemical level, it reacts with calcium hydroxide released by the
cement, turning the silica into a strong binder that helps hold together the
UHPC mixture And on a physical level, the silica particles, together with
the quartz flour, fill in all the small spaces between cement grains and any
coarser aggregate This tight packing keeps out water and chemicals that
can seep in and damage the concrete
U. S military leaders worry that Iranians are testing even smaller
par-ticles, nanoparpar-ticles, as additives to UHPC Some material experts estimate
that nanoparticles could boost UHPC’s already impressive strength by a
factor of four
The downside of UHPC is it is cost – 10 times that of normal concrete
It can also be more difficult to work with To maximize its strength, for
ex-ample, UHPC must be steam cured, a process that takes about 48 hr MD

There have already been attempts to make some
kinds of engineering software cloud-based But
re-sponse time has been an issue Users seeing a CAD
model called up from a server, for example, might notice a perceptible lag between moving a cursor on
a model and seeing the software finally respond This lag can be just an annoyance or it can bad enough to make real-time server interactions impractical.NVIDIA says it has eliminated such effects by removing about 100 msec from the chain of events that transpire between generating an image on a server and producing it on a remote PC or tablet Superfast graphics let CAD go to the cloud

NVIDIA also says delivering virtualized desktops this way can minimize the security risks inher-ent in sharing critical data and intellectual property For example, source data for CAD models need never leave a secure server, but can be manipulated by users across the globe in real time using the VGX scheme

Meltric Corp., Franklin, Wis., consists of prewired, switch-rated combination
plug/receptacle devices that are UL approved for disconnect switching
Replacing electric motors has always involved deenergizing power
cir-cuits and tagging and locking out the branch to prevent accidental

The plug-and-play Decontactor features a dead front, an enclosed arc
chamber, and a switching function that ensures live electrical contacts
are safely deenergized before the technician withdraws the plug from the
receptacle Once withdrawn, the plug visual verifies that power is

• Advanced manufacturing technology
and EMTs routinely rely
on trauma shears to cut
through a patient’s
cloth-ing and access a wound
that needs immediate
treatment These cutting
tools must slice through a
wide range of materials,
in-cluding denim, leather, and
even bulletproof Kevlar
Most trauma shears are
flimsy and poorly constructed
with blades that dull quickly
And they are typically used once
then thrown away But two
inven-tors — Scott Forman, an ER
physi-cian, and Mark Reece, a materials
engineer at Sandia National
Laboratory — got together to
redesign the shears Reece was
able to participate thanks to
the New Mexico Small
Busi-ness Assistance Program,
which pays scientists and
engineers inside Sandia
to work with outside
EMTs easily attach
the tool to a belt loop, keeping
it close at hand The hand length
and handle pivot point lets users
generate considerable torque
and expend less effort for heavy
cutting And the high-carbon
stainless-steel blades hold an
edge longer than previous models
but can also be resharpened The
entire shears can be sterilized in
an autoclave One of the blades is
serrated, letting it cut through Kevlar, bal-listic nylons, thick fabrics, and even fiberglass
The team also incorporated sug-gestions from EMT personnel So the shears include a rip-per attachment with replaceable blade for quickly slicing though clothing, a bottle opener for medications, a key for opening and clos-ing oxygen tanks, and
a window punch
The shears will likely be sold and marketed by
Héros, a
com-pany founded
by Forman The
Innovative trauma shears
make the cut
shears will cost from
$20 to $60, compared
to $5 to
$10 for typical throwaway versions But those who have tested the pro-totypes say they are much better and well worth the extra cost. MD

Tens of thousands of engineers and technical managers from across
Europe gathered in Northern Italy last month for a series of events loosely
termed Technology Exhibition week These included Fluidtrans
Com-pomac (fluid power), Mechanical Power Transmission and Motion Control,
Plast (plastics and plastics-processing machinery), Xylexpo (woodworking
machinery) — all held in Milan — and Lamiera (metal-forming
equip-ment), held in Bologna
Widespread interest in Italian components, machines, and technology
belies the country’s current economic conditions It’s no secret that Italy
is caught up in the European financial crisis and in a recession, with 2012
first quarter GDP declining 0.8%
ITALIAN TECHNOLOGY WEEK:
Small and nimble manufacturers are global problem solvers

Yet many Italy-based companies continue to prosper in spite of the
downturn Consider data from Federmacchine, the federation of Italian
machinery associations, based in Milan Its members manufacture
every-thing from machine tools, packaging equipment, and plastics
injection-molding machines to hydraulic and pneumatic components, robots, and
automation equipment Last year, production for the sector rose 13.2%
and exports were up 15.8% Italy accounts for 18% of the European
Union’s machinery production, second only to Germany
Why the ongoing success despite general hard times? Giancarlo
Losma, President of Federmacchine, cites several reasons, and they

cally revolve around performance,
customization, and after-sales
support
First, successful Italian
manu-facturers make machines of the
highest quality and take
advan-tage of the latest technological
innovations, says Losma
Produc-tivity and reliability need to be
second-to-none And because
the average manufacturer is fairly
small by U. S standards, with only
about 60 to 70 employees, this
lets them focus on problem
solv-ing and gives them the flexibility
to customize and personalize the
end product to exactly match
cus-tomer requirements
“Italians are the champions of special machines,” says Luigi Gald-
abini, Vice President of UCIMU, the
Italian machine-tool association
“We are innovative and tive, and we are artists, a little bit
competi-Who is solving problems? It is the Italians.”
He notes that OEMs from around the world don’t look to Italian manufacturers for a cheap price on conventional, run-of the-mill equipment “We will always get beat by China and India in terms of costs, with simple ma-chines Our aim is to be tops in performance, quality, and innova-
tion,” Galdabini says
The expertise of Italian trepreneurs lies in overcoming technical hurdles, crafting unique designs, and wringing out more efficiency, speed, precision, and productivity from a machine Some manufacturers might invest thousands of engineering hours yet only produce a single — albeit extremely complex — machine a year, he adds

Last year the Italian machinery sector exported 70% of its produc-tion In some segments it was even higher, for instance about 80% of textile machines were shipped abroad last year For many Italian manufacturers, Germany is the number-one customer, while ma-chinery exports to the U. S were
up about 35% last year, according
to Federmacchine
Another strength, notes Losma,
is many of these companies are multi-generational, family-owned operations with their livelihood
on the line “The way to survive is invest in technology, innovation, and internationalization,” he says
“Export-oriented companies that have invested over the last five years are still growing despite the poor domestic market.”
Smart materials
Case in point is Saes Getters, a
medium-size manufacturer quartered in Lainate The company manufactures a range of what can
head-be considered “high-tech” ucts such as ultrahigh vacuum systems for semiconductor manu-facturing, organic LED displays, and medical devices It invests 11

ficiency and substantially lower energy and operating costs — ensuring a practical, long-term investment
The firms also stress ing and support after the sale, building long-term relationships, says Losma “Customers need to understand we’re in for the long term.” All these factors give Italian manufacturers a leg up in global markets, according to Losma
train-Despite the companies’ relatively small size, they have structured their internal operations to focus
on, and sell their products, in eign markets
for-lems It’s the life blood of most
firms, which on average count 35%
of their employees as engineers,
technicians, designers, or software
developers “We typically turn
to outside experts for specialty
research, for example in
measure-ment systems or optics,” he says
Sustainability and energy
effi-ciency are growing in importance,
particularly in markets such as
Germany and Switzerland and,
to a certain extent, the U. S But
increasing efficiency can raise the
price of a machine, he cautions,
which often makes the sale more

transmission and control
Deutsche Messe, based in Hannover, Germany, and Milan’s Fiera Milano
have announced a joint venture, TPA Italia, a trade fair for power
transmis-sion and control, hydraulics, and pneumatics
It will be held every two years and alternate with MDA (Motion, Drive &
Automation), Deutsche Messe’s trade show for power transmission and
con-trol held in odd-numbered years as part of the Hannover Fair in Germany
Deutsche Messe looks to leverage its expertise and extensive network
of international contacts to create a strong regional trade show in Italy,
ac-cording to Andreas Gruchow, a member of the company’s managing board
“This will give companies in the power transmission and control industry a
high-caliber, well-run platform in the heartland of one of Europe’s leading
industrial nations,” said Gruchow
TPA Italia is endorsed by Italy’s leading power transmission and fluid
power industry associations, including Assofluid and Assiot The show will
include an exhibition and a supporting program of conferences and
net-working forums The inaugural event is slated for May 2014 in Milan
