From pink tube tops to hats and even facial hair dyed in pink,
straight and gay Singaporeans arrived at Speakers' Corner, a
government-designated free speech park, in the colour theme picked by
organisers to represent the freedom to love.
Some brought their dogs and cats in pink pet clothing and leashes.
"Singaporeans
gathered here today are saying that we want to be a kinder and more
inclusive society,"Ivan Heng, an ambassador for the organiser Pink Dot
Sg, told AFP at the park.
More Singaporeans have come to
understand that prejudice and discrimination hurts the community, our
families, and the people we work with,"said Mr Heng, who is also a
prominent local theatre director.
Organisers, who stressed that
the event was not a protest but a public show of support for lesbian,
gay, bisexual and transgender (LGBT) people, estimated that 21,000
people had attended.
It was the biggest crowd since the annual event started in 2009, when nearly 2500 people attended.
15,000 participated in the event last year, which counts Barclays Bank, JP Morgan and Google among its corporate sponsors.
The
three-hour gathering featured musical performances by Singaporean
artists, and culminated with the crowd forming a giant pink dot after
dusk by holding LED lights.
Lisa Sim, 29, said the event's growth
in stature since its inception showed that the LGBT community is
increasingly gaining social acceptance in the city-state.
"Straight
Singaporeans are realising that we are no different than them, and
deserve the same rights as them'', said Ms Sim, who attended the event
with her lesbian partner.
Law student Akesh Abhilash, 25, said
younger Singaporeans are more inclined to denounce calls from
conservative segments of society to retain Section 377A, a provision in
the penal code that makes it a crime for men to have sex with each
other.
"The gay community does not infringe on any one's rights.
It is ridiculous for others to claim to be able to dictate how they
should lead their lives,"he said.
While Section 377A is not
enforced actively by authorities, LGBT rights campaigners still see it
as a threat and demand its repeal.
Government officials maintain
that the law must stay in the books because most Singaporeans are still
conservative and do not accept homosexuality.
Singapore's High
Court in April rejected a petition to repeal the law, whose origins go
back to the 19th century when Singapore was a British colony, drawing
condemnation from international rights activists. More information about the program is available on the web site at www.hmhid.com.

L.E.D. There Be Light
In 2007, the Federal government passed a law mandating a gradual transition to more energy-efficient light bulbs. Manufacturers have already phased out 75 and 100-watt bulbs. And next January will be lights out for the old 40 and 60-watt energy hogs.
Turns out the light bulb Thomas Edison invented over 130 years ago is incredibly inefficient. It’s internal filament wire is basically a heat source that gives off light. Not bad for the 1880s, but considering 17% of the country’s total electricity consumption now goes to lighting our homes and businesses, we have an opportunity to reduce our energy footprint by relying on newer, more efficient options.
While CFLs – those swirly looking, Compact Fluorescent Lights – are certainly more energy-efficient than incandescents, disposing them has always been an issue. CFLs contain mercury, a toxic metal, and must be properly recycled when they burn out. And if they fall and break in your home, well, the EPA has a long list of cleanup precautions, including turning off your central air so the toxins don’t spread.
The real bright spot in the lighting aisle comes from LED bulbs.
These days LEDs can be found everywhere – flashlights, cell phones, street lamps - except the light fixtures in our homes. Why? Because up until now they were simply too expensive for most consumers. But that’s about to change.
This year Durham, North Carolina-based Cree introduced a $10, 40-watt replacement LED light bulb and a 60-watt replacement model that sells for $13. Both bulbs look and feel like incandescent bulbs, only better.
Before you write off the LEDs because of the steep price tag, consider this: their 60-watt replacement bulb is designed to last for over 22 years. That’s years. This translates into an estimated annual energy cost of $1.14. By comparison, a standard 60-watt incandescent bulb will burn out in about 11 months and add $7 to your annual energy bill. Consumer Reports crunched the numbers and says you will make your money back with Cree’s 60-watt replacement bulb in under two years; “After that you would save $149 in energy and bulbs over its life when compared with an incandescent.” How many light bulbs do you have in your home? You do the math.
But what about the light quality, you ask? For a long time the knock against CFLs and LEDs was that they simply can’t compete with the warm, bright glow from incandescents. We conducted a little field test to see how the bulbs compare:
Could you see a difference? From my perspective the light quality was pretty much the same. And I suppose that’s the point.
Bottom line: switching to LED bulbs is a no-brainer if you’re looking to reduce your energy consumption and your utility bill. Most reviewers highlight Cree’s bulbs for its price and light quality. But there are other options on the market, that span the price and light range so shop around and choose an LED bulb that works best for you. Click on their website hmhid for more information.

Topsham selectmen mull traffic issues
The Board of Selectmen on June 20 discussed ways to mitigate traffic
issues at two intersections, along with parking on Pleasant Street and
establishment of a drug-free zone at the Swinging Bridge.
Police Chief Christopher Lewis said after the meeting that traffic at Monument Place and Mallet Drive has raised some concerns, but statistics do not show they are high-crash locations. He said speed does not appear to be a factor in crashes; rather, most incidents have been a result of drivers coming out of Mallett Drive too early and hitting vehicles traveling along Monument Place.
The chief said the board asked him to look into installation of a caution light, along with additional street lighting, at the intersection.
At the other intersection the board discussed, Main and Pleasant streets, reports show crashes due to inattentive drivers or operating under the influence, resulting in rear-end collisions. Lewis said the board asked him to look into prohibiting drivers from passing on the right, since Selectman Ron Riendeau said motorists have been riding on the curb to get past vehicles waiting to left from Main Street onto Pleasant Street.
Since a driver riding a curb would, by state law, be passing improperly, the question is whether Topsham should draft an ordinance barring all passing on the right on Main Street, the chief said.
The Board of Selectmen also discussed parking concerns at Pleasant and Elm Street. Parking was allowed on the west side of Pleasant Street when a library stood there, but the narrow width of the road causes traffic to have to turn into the oncoming lane in order to get around parked cars, raising the potential of an accident with a vehicle heading north from Elm onto Pleasant.
Town Manager Cornell Knight said Lewis will report back on proposed changes to the ordinance that would ban parking on the west side of Pleasant Street.
The board also talked about a request from resident Jeff Deletetsky to establish a drug-free zone at the Swinging Bridge.
Since 2005, Lewis reported, there have been 10 arrests or summonses related to drugs, mostly due to traffic stops at that location. There have also been five alcohol offenses (not including warnings); 75 disorderly conduct complaints, which includes general disturbance of the peace and public drinking; 30 calls for criminal mischief; 102 for suspicious activity; four for littering, and one for an illegal camp fire.
However, since installation of the Riverwalk path, the number of complaints have decreased, Knight said, adding that Lewis reported that police have conducted 18 patrols since early May, and have seen no violations.
"They'll monitor the area, and if they see a problem developing, that a sign would assist in their enforcement, then they'll come back and ask for a sign to be put up," Knight said. More information about the program is available on the web site at www.hmhid.com.

More LED lamps to glow in Thiruvananthapuram
A demonstration project meant to replace the sodium vapour lights
along the Vellayambalam-Vazhuthacaud stretch with Light Emitting Diode
(LED)-based streetlights is showing signs of life after a hiatus of five
years.
It was first proposed in 2008 by the Energy Management Cell (EMC), functioning under the Power Department. Sources in the cell told The Hindu that they were forced to retender the works, which led to the delay.
Now, such processes had been completed, and the work order to install 70 lights along the one-kilometre stretch would be issued by the end of this month.
The project was designed to highlight the benefits of the more power-saving option of LED lights. It was sidetracked after the Chennai-based company carrying out the project demanded higher payment in the middle of implementation. Three poles and six lights were installed near the Forest Office Headquarters then.
Once the work order is issued, the project will take only three months to materialise. The 100-watt LED lamps will save over 60 per cent power.
The project is being sponsored by the Union Government agency, Bureau of Energy Efficiency (BEE). This project and another initiative of the EMC being sponsored by the BEE were attempts to nudge the city towards a more energy efficient lighting regime, said Johnson Daniel, energy technologist with the EMC.
The technical evaluation of companies who responded to the tender to install 500 LED-based lamps along the Kazhakootam-Kovalam bypass route was also almost complete and the financial bidding would open by July, he said.
Each of these 45-watt lamps would replace the double-tube fittings that fringed the highway. Again, the power consumed would be less than half of the tubes and could make a significant difference in the bills accrued by the city Corporation.
The civic body, however, is still making its choice on which mode of power-saving to employ for the street lights in the city – LEDs or those fuelled by electromagnetic induction – before inviting Expressions of Interest. So, it may time another year before the 84,000 streetlights in the city is switched over to a power-saving mode.
The Corporation limits have benefited from another project of the EMC — to install 100 LED streetlights in 65 municipalities across the State.
This was carried out in the Attukal ward here in January. Ward councillor C. Jayan said there were no complaints about the lamps except that people initially thought they were dimmer.
The EMC also has plans to move towards attaching each light with an almanac-based automatic street lighting system that will ensure no wastage of electricity with on-off timings accurately programmed in. More information about the program is available on the web site at www.hmhid.com.

2013 Hyundai Elantra GT
This stigma accounts for the lack of competition for this affordable
family truckster and it also accounts for the fact that you don’t see
the words “station” or “wagon” anywhere in the vehicle description but
at the end of the day - the Elantra GT is what Americans 20 years ago
would have called a station wagon. Fortunately, the Elantra GT is
engineered in such a manner that it avoids the aspects that caused the
negative reputation for “wagons” here in the US. It is as fuel efficient
and as nimble as the rest of the Elantra lineup while offering tons of
cargo space for objects of all sizes. It also avoids being so tragically
unhip as the old school soccer mom wagons of the 1980s that drove so
many people away from 5-door cars.
My test subject for this review was the 2013 Hyundai Elantra GT in Titanium Gray shown throughout this article. Options included the Style Package, which adds 17” alloy wheels, the sport suspension setup, the gorgeous panoramic sunroof, leather seats, a leather wrapped steering wheel, aluminum pedals and more. The total price of the test vehicle was $22,015. The only options not included that are available come as part of the Tech Package that adds navigation, daytime running lights, a backup camera system, dual zone climate and push button start.
The 2013 Elantra GT is a 5-door hatchback so it should be obvious that the biggest changes from the sedan come out back, where the back end is completely redesigned. In addition to the hatch, the GT rear end has its own unique lower fascia sculpting and taillights that are smaller and slightly more aggressive than the sedan’s rear blinkers.
Even though there is plenty of space on the “liftgate”, the license plate has been moved down to the lower fascia area with large, red reflectors that are not present on the sedan mounted on both sides. The rear hatch also wears a low profile spoiler that adds that little extra bit of sporty appeal to the rump of this compact 5-door. Like the sedan, the exhaust system is tucked up under the lower fascia, nearly out of sight for a nice clean look. Overall, while more aggressive than the sedan, the rear end of the Elantra GT is less fluid than the 4-door models with unique hard lines being created by the large rear opening.
Along the sides, the 2013 Hyundai Elantra GT very closely follows the design of the sedan with the only major difference being the obvious change in the profile caused by the elongated rear roofline of the hatchback design. Like the sedan, the roofline is very fluid from front to back with a hard body line running through the doors and into the taillights but the extra greenhouse space has allowed Hyundai to add an extra, smaller quarter window just behind the rear doors that add just a touch more visibility for the driver when attempting to change lanes on the highway or back out of the driveway.
The front end of the 2013 Hyundai Elantra GT has received the most distinct yet subtle revisions compared to the sedan. The headlights and grille are a similar shape on both versions but the GT packs HID projection headlights and a much sportier grille filler featuring a blacked out center section for that extra sporty appeal. The grille opening above the black center section is larger than that found on the sedan while the lower portion of the GT front end has downward angled bars that give it a more aggressive look than the upward angled bars on the sedan. This Elantra is frowning because it’s an aggressive model – it is a GT, after all. Finally, the lower front fascia of the GT has fog lights that sit in the same relative location as the sedan but on the 5-door, these extra lights are set in a contrasting housing rather than the molded units of the 4-door Elantra.

School District’s energy savings team pays off
The Marion County School District's energy team has saved taxpayers
on average nearly $2.7 million annually since 2005, according to a new
report.
The report, released last week, noted the entire district — 51 schools and dozens of district buildings — used 11 million fewer kilowatt hours in 2012 than it did in 2005.
School Board members said 16.2 percent electric savings is remarkable, especially since the district has added 1 million square feet of space — classroom wings and new schools — during the same period.
"To date, we have saved $18.6 million that we have been able to put back into the classroom," said Tommy Crosby, executive director of support services.
Though the district pays 47 percent more for utilities than it did in 2005, the overall utility cost per square foot has risen by only 3.2 percent during the same period. Marion paid 98 cents per square foot in 2012, while the state average for school districts was $1.21.
In 2012, the district used 59 million kilowatt hours of electricity. That was down from 61.6 million in 2011 and 70.4 million in 2005.
Since December 2005, the district's per-square-foot energy usage — which includes electricity, natural gas and other sources — has declined by 34.8 percent, according the report.
The energy management team was created in 2005 by the district to control energy costs. Officials announced the team has saved taxpayers $221,428 per month.
The program kicked off with a concerted effort to shut down computers overnight and flip off lights to cut electric costs. Every year since, the management team has inspected area schools looking for ways to implement more cost-saving measures.
Since the energy management team was created, electricity rates have risen by 45 percent. During the same period, metered water and sewer rates have increased by 37 percent.
Despite those rising unit costs, overall utility bills — including water and sewer — are still falling. The district spent $7.9 million dollars on utilities in 2012 — about $200,000 less than in 2011 and $1.24 million less than in 2010.
The Energy Use Index (EUI) — the kilowatt BTU per-square-foot usage for electricity, heating oil, natural gas and propane combined — hit an all-time low of 34.3 per square foot in 2012, down from 52.6 in 2005.
The 2012 school leader in electric savings was Maplewood Elementary, which had a savings of 24.9 percent or $22,000 between 2011 and 2012. The district used federal stimulus dollars to replace fluorescent light fixtures at Maplewood with LED fixtures.
Officials said though impressive, the LED lights are cost prohibitive to install at other schools, unless the district can get more grants. Read the full story at www.hmhid.com web.

User-Based Definition for Lamp Dimming
The Alliance for Solid-State Illumination Systems and Technologies, a
program of the Lighting Research Center (LRC) at Rensselaer Polytechnic
Institute, recently released a new publication that addresses the issue
of how lamps should dim in terms of their “look and feel” during the
dimming process.
The publication, ASSIST recommends… Dimming: A Technology-neutral Definition, provides a recommended definition for lamp dimming in residential and hospitality applications, based on research of existing industry standards, laboratory evaluations of lamp and dimming control performance, and psychophysical experiments conducted to determine common user expectations and preferences.
As new replacement lamp technologies become viable for many applications, manufacturers must design for the many facets of general illumination that the consumer expects, like dimming with standard wall dimmers. LEDs are intrinsically dimmable light sources and are commonly marketed as such; however, that does not mean that all integrated LED lighting products, particularly replacement lamps for incandescent lighting, are dimmable, or that residential dimmable LED products provide the same end-user experience when coupled with the existing installed base of dimmers.
Compact fluorescent lamps have similar issues as well. Thus, dimming has been often discussed as one feature that needs to work well for energy-efficient lighting to achieve widespread adoption in general lighting applications.
Even though dimming is a feature commonly expected in many lighting applications, there is no standard definition for dimming in the industry. Over a two-year period, researchers from the Lighting Research Center at Rensselaer Polytechnic Institute, on behalf of ASSIST, conducted technology performance and compatibility evaluations, human factors experiments, and reviews of existing industry standards to better understand the different aspects of lamp dimming.
The results of this research led to the published ASSIST recommends, which outlines recommended minimum and maximum light levels, thresholds for dead travel, flicker, and audible noise, and definitions for dimming profile and system efficacy measurement.
Nadarajah Narendran, Ph.D., LRC director of research and organizer of the ASSIST program, notes that the goal of ASSIST’s dimming recommendation is to have manufacturers understand and meet users’ expectations for dimmed lighting, helping LED technology to gain widespread use in lighting applications.
“The LRC and ASSIST’s industry members are interested in understanding the technical problems impeding market acceptance of LED lighting, and dimming is one focus area. By understanding the compatibility issues and what users want when they dim their lights, we can improve not only the dimming experience but also the likelihood that homeowners will permanently switch to energy-efficient LED lighting,” said Dr. Narendran.

Even though dimming is a feature commonly expected in many lighting applications, there is no standard definition for dimming in the industry. Over a two-year period, researchers from the Lighting Research Center at Rensselaer Polytechnic Institute, on behalf of ASSIST, conducted technology performance and compatibility evaluations, human factors experiments, and reviews of existing industry standards to better understand the different aspects of lamp dimming.
The results of this research led to the published ASSIST recommends, which outlines recommended minimum and maximum light levels, thresholds for dead travel, flicker, and audible noise, and definitions for dimming profile and system efficacy measurement.
Nadarajah Narendran, Ph.D., LRC director of research and organizer of the ASSIST program, notes that the goal of ASSIST’s dimming recommendation is to have manufacturers understand and meet users’ expectations for dimmed lighting, helping LED technology to gain widespread use in lighting applications.
“The LRC and ASSIST’s industry members are interested in understanding the technical problems impeding market acceptance of LED lighting, and dimming is one focus area. By understanding the compatibility issues and what users want when they dim their lights, we can improve not only the dimming experience but also the likelihood that homeowners will permanently switch to energy-efficient LED lighting,” said Dr. Narendran.

Isamu Noguchi's mid-century 'light sculptures' still popular
The round, white, paper light shades sold at Ikea for $5 are a
familiar item in contemporary interior design. But these inexpensive
lanterns are knockoffs of light sculptures created by the renowned
artist Isamu Noguchi in the early 1950s.
The Noguchi lamps — called akari, the Japanese word for light — were inspired by traditional Japanese lanterns used in ancestor worship. Over the decades, the akari became classics of mid-20th century modern home decor.
Noguchi’s original designs are still handmade in Japan; they come in a variety of colors and dozens of geometric designs — including the widely imitated white sphere — and range in price from $100 to $1,000. And they pop up in some pretty cool places, from painter Georgia O’Keeffe’s home in New Mexico to Tony Stark’s bedroom in “Iron Man 3.”
The story of how the late Noguchi came to create akari is rooted in the recovery of Japan’s post-World War II economy and the cross-cultural currents that influenced his spare, bold, modernist aesthetics.
Noguchi’s mother was American; his father Japanese. They never married. Born in 1904, Noguchi spent years in both countries during his youth. After World War II, he was greatly admired by the art and design community in Japan, and at some point met the mayor of the town of Gifu, where local industry centered around making lanterns for ancestry worship, using paper from mulberry trees.
“The mayor asked Noguchi, ‘Can you help us resurrect our lantern business?’ ” said Jenny Dixon, director of the Noguchi Museum in Long Island City, N.Y. “That’s how the akari were first produced. They were exported as an economic product and were well-received by the design community.”
She added that Noguchi “papered them sculpturally. He didn’t call them lanterns or lamps; he called them light sculptures.”
Noguchi’s concept “stood in sharp contrast to 1950s contemporary, modern, efficient lighting trends,” said Peter Barna, provost of Pratt Institute, the art and design college in Brooklyn, N.Y. Popular lighting options of the day included track lights, adjustable desk lamps and “pole lamps with conical shades,” added Barna, a former president of an international lighting design firm.
Noguchi’s designs were radically different, “a sculptor’s memory of the soft magic of material and light,” Barna said.
Eventually, Noguchi developed a relationship with one family of lantern makers. The same family still produces his designs today. “They’re all handmade, each one individually from molds. They’re not mass-produced,” Dixon said. “We’re now working with the third generation there, filling our orders. ... Our biggest challenge is meeting the demand.”
Depending on which lamp is ordered, “you might hit the jackpot and get a lamp right away or you can wait three to six months.” She added: “We lose a lot of business” from customers who don’t want to wait.
Each lamp has bamboo ribbing and standard wiring, and can accommodate incandescent or compact fluorescent bulbs (45 watts for small lamps, 75 watts for large). Designs range from spheres, discs and cylinders to triangles, boxes, trapezoids and other geometric shapes and combinations. Most shades are white, but some are decorated in orange, green or black; a few bear abstract designs.
There are hanging lamps, as well as table lamps and floor lamps with metal legs or small black circular bases. Many appear breathtakingly elegant; others have a whimsical, futuristic look. More information about the program is available on the web site at www.hmhid.com.

Semicon session will examine next steps for HB LED manufacturing
Moving on to LED manufacturing and materials, GaN-on-Si technology
has been a hot topic. Proponents believe it can deliver lower LED cost
because silicon wafers cost less than the sapphire wafers that are most
widely used today. Moreover, once the epitaxial process is complete,
manufacturers can use existing IC fabs and automated tools to handle the
back end of the production process.
"There's no answer yet about GaN on silicon, but there will probably be one within the next 12 to 18 months," suggests Eric Virey, senior analyst for LEDs at Yole Developpement. "It depends a lot on how successful Bridgelux and Toshiba are."
LEDs Magazine has closely followed the progress of the duo. Toshiba announced production start last December and released the detailed specs of its silicon-based LEDs in January.The lights used were Inspired LED Strip light in warm white Bridgelux has since sold its silicon-centric intellectual property to Toshiba, although the company still has an agreement to buy Toshiba LEDs.
Virey believs that if the Toshiba GaN-on-Si product proves extremely competitive in cost and performance, many of the other big players, who all have research programs, will follow. However, if the lower costs don't turn out to be significant enough to counter the likely somewhat lower performance, others will likely back off their efforts. The most likely scenario, argues Virey, will be somewhere in the middle, with GaN-on-Si adopted by some companies who have the silicon experience and the depreciated silicon fabs that make it most cost effective, and for some applications best suited to its cost and performance.
GaN-on-silicon wafer supplier Azzurro argues that the quality of LED devices made on silicon could be just as good with costs significantly lower – which could potentially mean big changes for the LED industry. The company sells 150-mm (6-in) and 200-mm (8-in) silicon template wafers with the buffer layers grown, ready for LED makers to grow their own light-emitting epitaxial structures on top, almost as usual, then finish processing on a standard silicon line.
Azzurro reports that it is now qualifying template wafers at its fab in Germany for customers who can start testing the process with 2-in template wafers. Epistar has reportedly ported its structures to the 150-mm template wafers. Wafer volume is also supported by demand from users making power semiconductors, where the GaN-on-Si technology has the added pull of a big gain in performance for most applications.
Azzurro co-founder and executive vice president of business development Alexander Loesing says the company inserts strain-engineering layers into its buffer stack to control the degree of bow after growth.Learn how daytime running lights use gas and the amount it takes to power these lights. The methodology also allows growth of a thicker GaN layer than most of the other buffer-layer technologies, which helps for making higher quality LEDs. After epitaxial growth, the excess silicon is thinned away with standard low cost removal processes, leaving wafers with the standard thickness and flatness required for processing on a standard silicon line.
"The strain-engineered wafers allow more homogenous processing for better control of wavelength, output power and forward voltage," claims Loesing. "Silicon actually has better thermal properties that can improve the temperature homogeneity across the wafer for more uniform epi growth, for tighter binning,You can add the car led and fluorescent kits to your car, truck, motorcycle, boat etc. though controlling bow during growth helps as well." The better yields and higher throughputs of the production workhorse 150-mm and 200-mm generation of silicon tools could reduce LED production costs – especially if companies don't have to invest in the equipment because they have their own depreciated fab already or can find a foundry to do the processing.
Azzurro argues that even when demand picks up enough to require the additional capacity, the economics of converting to 6-in sapphire wafers will be marginal for many companies because of the higher cost of the larger sapphire wafers and the technical challenges of more strain and bow across their larger area as well. Thus, switching to larger diameter GaN-on-Si template wafers with CMOS-foundry post-epi processing could be the more appealing path to staying competitive for many companies. "If someone comes in with GaN on silicon that's competitive in performance, then the price advantage will be compelling," says Loesing.

Ducati's Multistrada
Bikers are a crazy lot. One day they want to be on a bike with which
they can decimate the corners, while the next day they want to go
green-laning. But when a long weekend is in sight, they yearn for a long
haul. So, in an ideal world they would need four bikes, which for most
is a distant dream. But Ducati realised this dream by creating the
Multistrada.
So, the Multistrada 1200S at first glance is quite a big bike. Weighing 234 kg at full load and standing 1,480mm tall, it has quite a presence. The headlights in the 2013 version now sport an LED lighting system and the front screen is adjustable for height and a small cubby hole on the fairing next to the handlebar can be used to keep knick-knacks.
Mechanically there are plenty of changes. The Testastretta 11 degree engine gets repositioned injectors and now sport dual spark plugs per cylinder.You can add the car led and fluorescent kits to your car, truck, motorcycle, boat etc.
Max power, though, remains the same at 150bhp. I say max power because the Multistrada has four selectable riding modes. The Multistrada's 1,198cc engine comes to life with a deep growl that's loud enough to rouse the entire neighbourhood. The clutch is light; open the throttle gently and the bike takes off smoothly. Any sudden burst of the throttle reveals that the system cuts the power avoiding a wheelspin. Even in top gear, the bike pulls away cleanly to massive three digit numbers. The suspension adapts itself and absorbs bumps fantastically. But, in the sport mode all hell breaks loose.
Now, the Multistrada morphs into a precision tool and the next sections of the hills are a joy to ride.
The Pirelli rubbers provide good grip, and in conjunction with the stiffer suspension, gives confidence even to novices.Learn how daytime running lights use gas and the amount it takes to power these lights.The lights used were Inspired LED Strip light in warm white But, there is little margin for error as the power delivery is insane that is very close to superbikes accompanied by a meaty baritone from the exhaust. Not to forget that the DTC is toned down as well.
Sr. Supt. Jesus Cambay, director of the Baguio Police Office (BCDO), said the anti-holdup on taxicabs campaign dubbed as "LED Alert" program was intended to bring down the growing number of taxi robberies in the past several months.
"The LED Alert project will play a key role in significantly reducing taxi holdup incidents, especially during the night. Drivers will have the ability to alert people of a hold up being committed," Cambay said.
LED refers to the Light Emitting Diode mounted on the top of the taxicabs that alerts police and the public of an on-going robbery inside the vehicle. Drivers can switch it on using a secret switch.
Police records show a total of 16 holdups in the city from January to June this year. In 13 cases, the drivers were holdup victims, but in at least three cases, the drivers were suspected of robbing their passengers.
Baguio City Mayor Mauricio Domogan welcomed the initiative, which could alert people to call the police, serve as deterent against taxi robberies and help bring down crime in the city.
"Let us continue strengthening the partnership that we were able to establish so that we will be able to project the city as one of the most peaceful and orderly urban areas in the country," Domogan said.
"We will be reaping its fruits through the expected influx of tourists to the city in the coming months," the mayor said.

Silicon-based nanoparticles could make LEDs cheaper
Silicon-based nanoparticles could make LEDs cheaper
Light-emitting diodes,Learn how daytime running lights use gas and the amount it takes to power these lights. or LEDs, are the most efficient and environmentally friendly light bulbs on the market. But they come at a higher up-front price than other bulbs, especially the ones with warmer and more appealing hues.The lights used were Inspirea LED Strip light in warm white
Researchers at the University of Washington have created a material they say would make LED bulbs cheaper and greener to manufacture, driving down the price. Their silicon-based nanoparticles soften the blue light emitted by LEDs, creating white light that more closely resembles sunlight.
The company, LumiSands, started as a graduate student project for CEO Chang-Ching Tu, who received his doctorate in electrical engineering at the UW and just completed a stint as a postdoctoral researcher in materials science and engineering. This spring, the start-up company spun out from the UW Center for Commercialization, a process that its two founders hope will lead to signing a commercialization license for the technology.
LEDs give off light when electrons move through a semiconductor material.You can add the car led and fluorescent kits to your car, truck, motorcycle, boat etc. They are more efficient than standard incandescent or fluorescent bulbs, but they’re also pricier. That’s partly because within each LED lamp, expensive substances known as rare-earth-element phosphors help to soften the harsh blue light that LEDs naturally emit.
But these rare-earth elements are hazardous to extract and process. China controls nearly all of the market for these materials, which has quadrupled the average price for the past several years.
That’s where LumiSands comes in. The company uses silicon, derived from sand, instead of rare-earth elements to convert part of the blue light emitted by LEDs into greens, yellows and reds. The resulting light looks more like sunlight.
The crew of two plans to sell directly to LED-bulb manufacturers that are looking to transition away from increasingly more expensive materials to make the lights.
“Hopefully, manufacturers could substitute traditional rare-earth elements with our material with minimal additional steps,” said Ji Hoo, a UW doctoral student in electrical engineering and co-founder of LumiSands. “It will be cheaper, better-quality lighting for users.”
Incandescent bulbs give off light that’s most similar to sunlight – and easiest on our eyes – but the bulbs are inefficient and produce a lot of heat. Fluorescent bulbs, seen most commonly as long tubes in overhead office light fixtures, are more efficient than incandescent lights, but they contain mercury, posing health and environmental concerns.
LumiSands etches off nano-sized particles from wafers of silicon. The element, which usually doesn’t emit light, can start to glow when its crystalline particle size is smaller than 5 nanometers. The surface is reinforced through a wet-chemistry process. When the red-emitting silicon nanoparticles are added to LED bulbs, the light becomes softer and warmer in hue.
“The beauty of our technology is to create a highly efficient fluorescent material by using silicon rather than rare-earth elements or other types of heavy-metal compound semiconductors,” Tu said. “The manufacturing process can be performed in a basic laboratory setting and is easy to scale up.”
LumiSands plans to tweak the red technology before moving on to other colors such as yellow and green, which will enable LEDs to cast a white light with no rare-earth elements.
The company has received funding from the National Science Foundation, the Washington Research Foundation and the W Fund. It received an honorable mention in the 2012 Foster School of Business Environmental Innovation Challenge and a top award in the 2012 Jones Milestones/Foster Accelerator mentorship program.

Fluorescent bulbs, seen most commonly as long tubes in overhead office light fixtures, are more efficient than incandescent lights, but they contain mercury, posing health and environmental concerns.
LumiSands etches off nano-sized particles from wafers of silicon. The element, which usually doesn’t emit light, can start to glow when its crystalline particle size is smaller than 5 nanometers. The surface is reinforced through a wet-chemistry process. When the red-emitting silicon nanoparticles are added to LED bulbs, the light becomes softer and warmer in hue.
“The beauty of our technology is to create a highly efficient fluorescent material by using silicon rather than rare-earth elements or other types of heavy-metal compound semiconductors,” Tu said. “The manufacturing process can be performed in a basic laboratory setting and is easy to scale up.”
LumiSands plans to tweak the red technology before moving on to other colors such as yellow and green, which will enable LEDs to cast a white light with no rare-earth elements.
The company has received funding from the National Science Foundation, the Washington Research Foundation and the W Fund. It received an honorable mention in the 2012 Foster School of Business Environmental Innovation Challenge and a top award in the 2012 Jones Milestones/Foster Accelerator mentorship program.

Noguchi's light sculptures
The Noguchi lamps — called akari, the Japanese word for light — were
inspired by traditional Japanese lanterns used in ancestor worship. Over
the decades, the akari became classics of mid-20th century modern home
decor.
Noguchi’s original designs are still handmade in Japan; they come in a variety of colors and dozens of geometric designs — including the widely imitated white sphere — and range in price from $100 to $1,000. And they pop up in some pretty cool places, from painter Georgia O’Keeffe’s home in New Mexico to Tony Stark’s bedroom in “Iron Man 3.”
The story of how the late Noguchi came to create akari is rooted in the recovery of Japan’s post-World War II economy and the cross-cultural currents that influenced his spare, bold,Learn how daytime running lights use gas and the amount it takes to power these lights. modernist aesthetics.
Noguchi’s mother was American; his father Japanese.The lights used were Inspired LED Strip light in warm white They never married. Born in 1904, Noguchi spent years in both countries during his youth. After World War II, he was greatly admired by the art and design community in Japan, and at some point met the mayor of the town of Gifu, where local industry centered around making lanterns for ancestry worship, using paper from mulberry trees.
“The mayor asked Noguchi, ‘Can you help us resurrect our lantern business?’” said Jenny Dixon, director of the Noguchi Museum in Long Island City, New York. “That’s how the akari were first produced.You can add the car led and fluorescent kits to your car, truck, motorcycle, boat etc. They were exported as an economic product and were well-received by the design community.”
She added that Noguchi “papered them sculpturally. He didn’t call them lanterns or lamps; he called them light sculptures.”
Noguchi’s concept “stood in sharp contrast to 1950s contemporary, modern, efficient lighting trends,” said Peter Barna, provost of Pratt Institute, the art and design college in Brooklyn, N.Y. Popular lighting options of the day included track lights, adjustable desk lamps and “pole lamps with conical shades,” added Barna.
Eventually, Noguchi developed a relationship with one family of lantern makers. The same family still produces his designs today. “They’re all handmade, each one, individually, from molds. They’re not mass-produced,” Dixon said. “We’re now working with the third generation there, filling our orders. … Our biggest challenge is meeting the demand.”
Each lamp has bamboo ribbing and standard wiring, and can accommodate incandescent or compact fluorescent bulbs (45 watts for small lamps, 75 watts for large). Designs range from spheres, discs and cylinders to triangles, boxes, trapezoids, and other geometric shapes and combinations. Most shades are white, but some are decorated in orange, green or black; a few bear abstract designs.
There are hanging lamps, as well as table lamps and floor lamps with metal legs or small black circular bases. Many appear breathtakingly elegant; others have a whimsical, futuristic look.
A large selection of akari can be seen at the Noguchi Museum, located in the studio where he worked for decades in Long Island City, an industrial neighborhood in the New York City borough of Queens. A few lamps are displayed amid Noguchi’s sculptures.
Danielle Berman, the production designer for “Iron Man 3,” chose a tall Noguchi lamp in a stacked box design to illuminate Tony Stark’s bedroom. “It was such a modernist home,” she explained. “It had a lot of very round, organic lines. I immediately thought of that lamp because it was such a geometric contrast.”
Noguchi’s “understanding of space,” she said, is “very organic. He uses all these natural materials. It’s the simplicity, yet it’s very complex. You light it and the paper gives this beautiful glow. It’s a beautiful element to have on any set. I try to use them whenever I can.”

RPI’s Smart Lighting ERC demos first monolithic integration of LED
The Smart Lighting Engineering Research Center at Rensselaer Polytechnic Institute (RPI) in Troy, NY, USA has demonstrated what is reckoned to be the first monolithically integrated light-emitting diode (LED) and high-electron-mobility transistor (HEMT) on the same gallium nitride (GaN) chip. It is reckoned that the development could open the door to a new generation of LED technology which is less expensive to manufacture, much more efficient, and which enables new functionalities and applications beyond illumination.
In existing LED lighting systems, for the LED to function, external components — such as inductors, capacitors,Buy hid kit, ballasts, and headlight bulbs. silicon interconnects, and wires — must be installed on or integrated into the chip. Due to these essential components, the large size of the chip complicates the design and performance of LED lighting products. Additionally, the process of assembling the complex LED lighting systems can be slow, manually intensive, and expensive.
In a study ‘Monolithic integration of light-emitting diodes and power metal-oxide semiconductor channel high-electron-mobility transistors for light-emitting power integrated circuits in GaN on sapphire substrate’led by T. Paul Chow, professor in the Department of Electrical, Computer, and Systems Engineering (ECSE) at RPI, the researchers hence sought to develop a chip with components all made from GaN. The monolithically integration simplifies LED device manufacturing, requiring fewer assembly steps and less automation. Also, LED devices made with monolithically integrated chips will have fewer parts to malfunction, higher energy efficiency and cost effectiveness, and greater lighting design flexibility, it is reckoned.
The research team grew a GaN LED structure directly on top of a GaN HEMT structure. Using basic techniques to interconnect the two regions, they created what is reckoned to be the first monolithic integration of a HEMT and an LED on the same GaN-based chip. The device, grown on a sapphire substrate, demonstrated light output and light density comparable to standard GaN LED devices. Chow reckons that the study is a key step toward creating a new class of optoelectronic device: the light-emitting integrated circuit (LEIC).
“Just as the integration of many silicon devices in a single chip — integrated circuits — has enabled powerful compact computers and a wide range of smart device technology, the LEIC will play a pivotal role in cost-effective monolithic integration of electronics and LED technology for new smart lighting applications and more efficient LED lighting systems,” Chow says.
“LEICs will result in even higher energy efficiency of LED lighting systems,” comments Smart Lighting ERC director Robert Karlicek, a co-author of the study and ECSE professor at RPI. “But what will be even more exciting are the new devices, new applications, and new breakthroughs enabled by LEICs — they will truly usher in the era of smart lighting.”
Along with Chow and Karlicek, co-authors of the paper are: Christian Wetzel, the Wellfleet Constellation Professor of Future Chips at Rensselaer and a faculty member in the Department of Physics, Applied Physics, and Astronomy; Rensselaer graduate students Zhongda Li and John Waldron; and former Rensselaer research associate professor Theeradetch Detchprohm.
The research was funded by the US National Science Foundation (NSF) through the Smart Lighting ERC, with additional support from New York state though Empire State Development’s Division of Science, Technology and Innovation.

Park District Celebrates the Grand Opening of Chippewa Pool
Construction, under the direction of Paul Cathey, the Park District Superintendent of Parks and Planning, Glen Anderson for the General Contractor, Nicholas & Associates, and Ed Kelley, the district’s Mechanical Maintenance Supervisor, proceeded according to schedule throughout the warm winter, and opened on time after passing final Inspection by the Department of Health on May 31. This inspection process certifies that Chippewa Pool is compliant with all the rules and regulations set forth in the Bathing and Swimming handbook.
At the 2010 public meeting, residents expressed interest in having the look of the new pool fit with the general feel of the neighborhood. Cordogan, Clark & Associates, the architectural firm for the project, designed a Tudor-inspired bathhouse with a steeply pitched roof, an open arch above the entrance, and prominent gables to coordinate with the style of the older homes in the area. Residents also wanted the facility to remain a “neighborhood pool”, as opposed to a water park. New Chippewa Pool occupies the same footprint as the old pool, but has many additional state-of-the art amenities.
In the Leisure Pool area, the shallow end has a zero depth entry, and five geysers that shoot continuous fountains of water into the air. The shallow end also has a Fumbling Five: an omnipod with five buckets in a star pattern. As the buckets constantly fill and randomly spill, they create a large variable splash area. At the opposite end of the Leisure Pool is a new tot-size slide for, swimmers under 48 inches, which splashes riders onto a non-slid pad in just two feet of water. The Lap Pool is connected to the Leisure Pool and can be configured with six standard 25-yard lanes for competitive or recreational swimming.
When not in use for swimming laps, a lane line divides the lap pools at the five-foot depth mark. In the deep end there is a three-meter diving board and another drop slide for swimmers over 48 inches tall. On the deck, a permanent shade structure and shade umbrella offer respite on sunny days, and new chairs and chaise lounges are perfect for sun bathing. In addition to men’s and women's locker rooms, the bathhouse also has a family locker room. There are lockers both in the locker rooms and on the deck, free to users, which can be secured with a standard combination padlock. Adjacent to the bathhouse is a new, covered concession area with picnic tables, two water and soft drink vending machines, a snack machine with healthy alternatives, and an ice cream dispensing machine.
Many new “green initiatives” are in place at Chippewa Pool. The Park District is testing green cleaners that are better for the environment, along with a wall-mounted metered dispenser that will help save money and create less waste. A recycling program is in place. Fluorescent lighting was installed, replacing the metal halide lights. This provides for energy savings in several ways: 1. The new ballasts and lights use much less electricity than the metal halide ones. 2. Fluorescents have instant on and off capability; no electricity is wasted during a warm up period. 3. The new light bulbs and fixtures are less expensive to replace and maintain. LED soffit site lighting was installed, remotely controlled by computer, providing additional cost savings. The Defender pool filter that was put in place will save thousands of gallons of water each year and provide significant energy savings. Finally, a new electronically fuel injected lawn mower was purchased to maintain the grounds. The new mower uses substantially less gasoline.
“The entire process was a team effort,” said Paul Cathey, “From the residents’ input, to the architect’s beautiful design, and the General Contractor’s hands-on management of the construction, everyone worked closely with the Park District staff, and the result is a pool that enhances the neighborhood in every way.” “I couldn’t be more pleased that the Park District has delivered another new facility that Des Plaines residents will enjoy for many years to come,” Cathey said.

Drive Cost-Competitive Next Generation Efficient Lighting
Building on his strong focus on energy efficiency in his first few days in office, U.S. Energy Secretary Ernest Moniz announced today five manufacturing research and development projects to support energy efficient lighting products. The projects will focus on reducing manufacturing costs, while continuing to improve the quality and performance of light-emitting diodes (LEDs) and organic light-emitting diodes (OLEDs). Today’s LED lighting is six or seven times more efficient than conventional lighting and can last up to 25 times longer. The Energy Department’s $10 million investment is matched dollar for dollar by private sector funding.
“This partnership with industry to produce affordable, efficient lighting will save consumers money and create American jobs,” said Energy Secretary Ernest Moniz. “It’s another example of how energy efficiency is a win-win proposition for our economy.”
According to a new report by the Energy Department, LED lamps and fixtures installed in the United States have increased 10-fold over the last 2 years – from 4.5 million units in 2010 to 49 million units in 2012. These installations, which include common indoor and outdoor applications such as recessed lighting and streetlights, are expected to save about $675 million in annual energy costs. During the same period, the cost of an LED replacement bulb has fallen by about 54 percent. Switching entirely to LED lights over the next two decades could save the U.S. $250 billion in energy costs and reduce electricity consumption for lighting by nearly 50 percent. By 2030, LED lighting is projected to represent about 75 percent of all lighting sales, saving enough energy to power approximately 26 million U.S. households.
Still, while life-cycle costs are attractive, the initial price of LED and OLED lighting is currently higher than the price of traditional lighting. The projects announced today will help achieve significant cost reductions in manufacturing equipment and processes, while improving lighting quality and performance:
This project will develop a modular design for LED lights that can link together multiple units to fit larger areas. The design will also use less raw material, reducing manufacturing costs while ensuring high lighting quality and efficiency. Cree’s approach will design and manufacture the different components of an LED fixture -- including electrical, mechanical and optical systems – as one, seamless product, helping to further reduce assembly costs and ensure strong performance.
The Eaton project will develop an innovative manufacturing process that streamlines the LED fixture design and removes unnecessary materials and parts. With this approach, the LED chip can sit directly on the heatsink, improving heat transfer within the design and increasing LED efficiency.
Organic LEDs, or OLEDs, are typically assembled through transfer or screen printing. The OLEDWorks project will develop and demonstrate new spray printing equipment that reduces overall manufacturing costs and could help support cost-competitive mass production. This technique will give manufacturers greater spray control to take full advantage of expensive organic materials and maximize the visible light produced from this material.
Most LEDs are grown on a sapphire substrate. Through this project, Philip Lumileds will develop an alternative to the standard flip-chip device that grows an LED face-down on the sapphire substrate. Before light can shine through, this substrate must be carefully etched off the device. The Philips Lumileds device will treat the sapphire substrate so that removing the substrate is not necessary – reducing manufacturing costs without compromising lighting quality.
