Black Rolex Watches Revealed: First
Video to Show Top-Secret Rolex PVD 'Blackening' Process Released
by Debra Tone, June 21, 2010
LOS ANGELES, Calif. (SEND2PRESS NEWSWIRE) -- Time and Gems (www.TimeandGems.com), an independent
Rolex retailer offering premium Rolex customizations, releases a video on their
website that shows in detail the top-secret PVD (Physical Vapor Deposition)
process that many fine Swiss watch manufacturers are using to coat stainless
steel watches with an all-black highly scratch-resistant coating.
"After launching our PVD Rolex watches in December, we
had a phenomenal response," says Jason Smith, president of Time and Gems.
"Our customers would often ask how we did it and whether the PVD coating
was really better than stainless steel and equal in quality to the Rolex watches
we were coating. The video really answers all their questions and more, showing
our first-class attention to detail and why we're the online leader in
The PVD process not only transforms the look of stainless
steel watches, but also surpasses stainless steel in terms of toughness. The
PVD process occurs in a vacuum chamber, at Time and Gems' multi-million dollar
coating facility, interpenetrating the steel with a DLC (Diamond Like Carbon)
coating and providing a chemical barrier on the watch that protects against the
elements, reduces the effects of oxidation and increases the hardness rating by
almost 20 times.

PVD Coatings for Medical Device Applications
By Mark Pellman, Multi-Arc, Inc. Rockaway, NJ
Since it was introduced to the medical
device industry in the late 1980s, physical vapor deposition (PVD) has become
widely used to deposit wear-resistant thin-film coatings on a variety of
medical devices, including orthopedic implants, pacemakers, surgical
instruments, orthodontic appliances and dental instruments. The value of PVD
technology rests in its ability to modify the surface properties of a device
without changing the underlying material properties and biomechanical
PVD Coating Properties
and Medical Devices
PVD coatings provide a number of benefits to medical devices in addition to
hardness and adhesion. The most significant are listed in Table I. The
biocompatibility of a coating is a prerequisite to its use on medical devices.
For this reason, Multi-Arc has tested the biocompatibility of all the coatings
that it applies, with the exception of TiN, which has been widely reported to
Coatings are certified biocompatible based
on a series of tests conducted by an independent biological-testing laboratory.
These tests were conducted in accordance with ISO 10993-1 guidelines for
materials that experience short-term body contact. The results indicate that TiN,
ZrN, CrN, TiAlN, AlTiN and two Multi-Arc proprietary coatings (Blackbond and
Tetrabond) are acceptable for external and internal medical devices that
contact bone, skin tissue or blood.

CSIRO to Build Largest Waterless Brayton Cycle
Solar Power Tower
The CSIRO (Commonwealth Scientific and Industrial Research Organisation) will be building the largest 30 m high
solar power tower with a Brayton Cycle Turbine on the top. The uniqueness is
that this turbine uses superheated compressed air as its energy transfer
medium. Sunlight is focused using 450 mirrored heliostats. Water is not necessary for operation, which makes the technology useful in
very arid climates. The plant covers an area of 4,000 sq. m and can operate at
above 900˚C. The field is expected to be fully operational by March 2011. $5
million in funding was provided by the Australian Solar Institute (ASI)-part of
the Australian Government Initiative.
The Visually Impaired Can Taste Light
Neuroscientists at Wicab, based in Wisconsin,
have a device that partially restores the experience of seeing by using the
tongue and camera system together as a substitute for the eye. The device, BrainPort, gathers visual
data with a small video camera mounted on sunglasses worn by user. The data goes to handheld base unit,
which converts digital signals into electrical pulses. The gentle electrical patterns are sent
to the tongue via a "lollipop", an electrode array around nine centimeters
square. The tongue is an ideal
sensor because of its sensitive and densely packed nerve fibers. The tongue feels tingle patterns
showing the texture of light and colors.
Patients typically need only 15 minutes to begin interpreting
Brainport's spatial information.
Wicab's video shows a patient successfully ascending a climbing wall on his
own. In the UK, Brainport is
funded jointly by the Ministry of Defense and St. Dunstan's, the charity for
blind ex-service personnel. Wicab will
submit it to the U.S. Food and Drug Administration for approval. The cost of the technology is about
$10,000 a unit.

LEDs: The Next Fabrication Wave
With the saturation of semiconductor fabrication
lines and the slowing of the solar markets, the next big thing is LED
fabrication plants. We are seeing rising demand for LEDs coming from lighting,
TV and electronic backlight applications. The Semiconductor Manufacturing Organization
(SEMI) has tracked 91 fabs and 89 optoelectronics fabs worldwide. Large
companies like Samsung and Taiwan Semiconductor Manufacturing (TSMC) are moving
into this area. Samsung will be installing 50 MOCVD new deposition systems to
make a total of 150 by year-end. New lines are expected in China, Taiwan,
Japan, India, Russia and India. The lead in the industry is Nichia of Japan,
announcing a quadrupling of their LED production. TSMC in Taiwan has announced
a lighting manufacturing line, which will have 10-12 MOCVD reactors. Equipment
makers Veeco and Aixtron have seen an upturn in orders. The estimated worldwide
spending on LED fabs in 2010 is $945 million with $60 million in North America,
according to SEMI. SEMI has recommended that the US government provide $20 million
for US manufacturing improvements for solid-state lighting through the American
Recovery and Reinvestment Act.

Glass-Ceramic Covers for Highly Efficient Solar Cells
Ralf B. Wehrspohn is the founder and head of the "SiLi-nano" research initiative at the Martin-Luther-University (MLU) of Halle-Wittenberg,
Germany. "SiLi-nano" stands for "Silicon and
Light: from macro to nano". SiLi-nano is used in the cover technology for silicon
photonics and photovoltaics. Conventional single bandgap
solar cell wastes much of UV and IR solar energy.By using fluorescent downshifting compositions, the
absorption of high-energy photons in the UV and the subsequent emission of a
photon with lower energy can be absorbed more efficiently by a solar cell.
Frequency 'downshifters,' such as fluorescent glasses and glass ceramics doped
with rare-earth ions can convert the high-energy part of the solar spectrum
into photons in the visible spectral range.
Researchers at SiLi-nano are using, divalent europium,
Eu2+, as the frequency 'downshifter to convert the high energy part
of the solar spectrum into photons in the visible spectral range.

DOE 'GATEWAY' Program Tests LED Street Lights on a Wide Scale
The U.S. Department of Energy (US DOE), Energy
Efficiency & Renewable Energy, estimates that by converting over 34 million
streetlights to LED lighting over the US, we could save more than $750 million
a year in energy costs. The US
government, regional governments, and LED manufacturers are working in partnership
to make this happen. The risk is that rapid expansion in LED manufacturing all
over the world may result in poor quality products tainting LED's benefits, as
noticed when CFL lights were first introduced.
The DOE GATEWAY program is a collaboration with
municipalities to test LED lighting products and provide feedback to
municipalities and manufacturers.
Several cities have performed market-based, real testing of LED lighting
on city-owned property. In San Francisco's Sunset District, four manufacturers'
LED street lights were installed on four public avenues to replace 100-watt
nominal high-pressure sodium lamps.
Seattle, WA was chosen to lead the DOE-supported consortium dedicated to
testing efficiency and effectiveness of LED lighting for public use. Edward Smalley is Seattle City Light
manager and director of the consortium.
He stated "The goal of the consortium is to reduce needless
duplication, reduce mistakes on a large-scale, bring end-users up to scale and
identify good products, and provide information in a timely way." Seattle
City Light must recruit at least 50 other communities to join the consortium
and share their experiences through national, regional meetings and web-based
discussions. Pacific Northwest
National Labs will administer the consortium.
LED manufacturers actively support the testing effort. For example, Cree LED
CityŽ program in Raleigh, NC conducted nearly 40 separate LED projects around
the city in various lighting situations with three-fold increase in positive
reactions. Other cities involved
in the LED City program include Los Angeles, CA, and Fairview, TX, which won
several design awards for its installation. Also, Dialight plans to test LED street lights in Pittsburgh
and Edinburgh, PA, which communicate wirelessly allowing the city to remotely
dim or control clusters of lights.

Many Technologies of the 21st Century are Vulnerable to Solar Storms
From Tony Philips, science.nasa.gov, June 4, 2010
Earth and space are about to come into contact in
a way that's new to human history. To make preparations, authorities in
Washington DC are holding a meeting: The Space Weather Enterprise Forum at the
National Press Club on June 8th.
Richard Fisher, head of NASA's Heliophysics
Division, explains what it's all about: "The sun is waking up from a deep
slumber, and in the next few years we expect to see much higher levels of solar
activity. At the same time, our technological society has developed an
unprecedented sensitivity to solar storms. The intersection of these two issues
is what we're getting together to discuss." The National Academy of
Sciences framed the problem two years ago in a landmark report entitled
"Severe Space Weather Events-Societal and Economic Impacts." It noted
how people of the 21st-century rely on high-tech systems for the basics of
daily life. Smart power grids, GPS navigation, air travel, financial services
and emergency radio communications can all be knocked out by intense solar
activity. A century-class solar storm, the Academy warned, could cause twenty
times more economic damage than Hurricane Katrina.

Want More Jobs? Fix the Broken Patent System
By David Goldman, Staff Writer, CNNMoney.com, June 21, 2010
NEW YORK (CNNMoney.com) -- After decades of
inaction, lawmakers are finally closing in on a sweeping overhaul of America's
antiquated, underfunded and extremely broken patent process. The popular move
could help spur much-needed innovation and job creation -- but first, it has to
get through a Senate logjam.
The Senate Judiciary Committee passed a bill in
April that would patch a litany of problems with the patent system, which
hasn't had a major reform in more than five decades. Two months later, the measure
still has no timetable for the Senate-wide vote needed to move it through
"I don't know why this hasn't gotten floor
time," Senate Judiciary Committee Chairman Patrick Leahy, D-Vt., said in a
recent interview. "This has nothing to do with ideology. We need an
updated patent system to create and protect jobs, and it wouldn't add a penny
to the deficit."
Leahy noted that the bill has three Republican
co-signers, along with three Democrats. As a result, he predicted that once it
gets floor time, the bill could get passed in just three days -- a blink of an
eye compared to the marathon sessions it took to get stimulus, health care and
financial reform passed.
The House has two similar bills under consideration,
though its versions aren't as far along as the Senate's. If the Senate bill
gets passed, it would likely make its way through the House fairly quickly,
But with patent reform, nothing is ever that
simple. House Judiciary Committee Chairman John Conyers, D-Mich., has said he
has concerns about some aspects of the Senate bill. The differences would have
to be hammered out by the two chambers.
