SPIE Counts Advances in Sustainable Photonics on List of Solutions to Celebrate on Earth Day


Bellingham, WA, US and Cardiff, UK (PRWEB) April 19, 2013

Events around the world will celebrate Earth Day on Monday 22 April, drawing attention to global challenges such as adapting to climate change, generating renewable energy, and attaining sustainability in everything from local food sources to investment choices. Photonics technologies, powerful drivers behind advances in every facet of life, are demonstrating their green nature as well, noted event organizers at SPIE, the international society for optics and photonics.

Sustainable photonics are at work in the form of photovoltaics for generating energy from sunlight, solid-state lighting (SSL) for cheaper, more efficient, longer lasting light sources, sensors to detect ocean temperatures and monitor the effect on fish populations, and numerous other applications.

An annual conference on sustainable photonics held at SPIE Photonics West in San Francisco highlights papers in which research in the field enables development of new technology that can improve standards of living and save money and resources. To emphasize the importance of this research, this year SPIE recognized four papers with Green Photonics Awards.

Photonics innovations enable improved sustainable products and services worldwide. The winners of this years Green Photonics Awards are exemplary in this regard, said Stephen Eglash, Executive Director of the Energy and Environment Affiliates Program at Stanford University, and founder and chair of the green photonics symposium. Each of the winning papers provides new information to help solve existing problems using photonics.

Published award papers are available for free download in the SPIE Digital Library through 31 July.

Next-generation lighting

SSL utilizing light-emitting diodes (LEDs) is the new industry standard for energy efficiency, and the rapid development of LEDs has flooded the lighting market, Eglash said. LEDs are efficient and long-lived sources for general lighting, but commercially available products exhibit variable quality.

Carsten Dam-Hansen and Technical Univ. of Denmark colleagues Anders Thorseth, Dennis Corell, and Peter Poulsen tested a large number of LED lamps to evaluate quality and lifetime, as reported in their paper “Light quality and efficiency of consumer grade solid state lighting products.”

It is the project groups hope that we internationally can work together on test and characterization so the data can be shared all over the world to benefit the individual nation importing or producing the products, Thorseth said.

Cheaper solar power

High-efficiency solar cells are needed to decrease the cost of solar energy, Eglash said. Solar cells that use thin absorber layers cost less and require less of the Earths materials. But inefficiencies of conventional light trapping techniques limit the ability to reduce the thickness of thin-film solar cells.

In one of two papers recognized in this area, “The photovoltaic potential of femtosecond-laser textured amorphous silicon, authors Meng-Ju Sher, Benjamin Franta, Kenneth Hammond, Lysander Christakis, and Eric Mazur of Harvard University told how they used femtosecond laser texturing to reduce reflection and enhance light absorption, enabling high efficiency from thin absorbers.

Specialty Steel Manufacturer Makes Better Products with IQinVision

San Juan Capistrano, CA (PRWEB) June 19, 2012

IQinVision (http://www.iqeye.com), market leader in high-performance HD megapixel IP cameras, today announced that the Ellwood Group, Inc. (EGI) is deploying over 250 IQeye HD megapixel cameras and growing, in order to monitor and improve manufacturing processes, in addition to meeting security needs. Compass Network Services is the integrator for this on-going project.

Headquartered in Ellwood City, Pennsylvania, EGI produces engineered, heavy metal sections for capital specialty equipment manufacturers in the United States and around the world. The company’s nine operating business unitsencompassing multiple plants in Pennsylvania, Michigan, Ohio, Texas and Canadaare dedicated to solving customers’ needs for specially engineered forging steels, iron castings, forgings, and other alloy parts.

We have moved from a test environment over five years ago to now having megapixel cameras deployed at about 20 different locations in our various plants, said Eugene Spadafore, Senior Network Administrator, EGI. We started out asking, How can we improve quality for process X? Rather quickly we saw the value of closely monitoring manufacturing with the IQeye cameras and now its a standard in our environment, we use the cameras at every facility.

Spadafores division has developed a de facto standard, scope of work, and set of specifications for how to successfully deploy the IQeye cameras in each new location. All the cameras are riding on our network, so in order to maintain consistency and best practices, we elected to be the overall project manager for camera deployment. As one location or division discovered the benefits of this kind of manufacturing process monitoringboth live and post-eventthey, too, would request cameras. We wanted to be able to control the roll-out in an organized, efficient way.

When making a single product that can cost tens of thousands of dollars, it is critical that we have the capability to record the manufacturing process and if we experience an issue downstream, were able to go back and find the root cause, Spadafore explained. If we can quickly solve manufacturing problems, the system pays for itself in short order.

In addition to the 10 manufacturing facilities that now use IQeye HD megapixel cameras for process monitoring, additional cameras at those locations are also used for monitoring overall security as well. I estimate we use our cameras 75% for process monitoring and 25% for general security, said Spadafore.

EGI stores video at each location anywhere from three days to three months, depending on the manufacturing process being recorded. The majority of the cameras are 2.1 MP IQeye Sentinel and 700-series cameras, the newest utilizing H.264 compression.

Our growth is typically through acquisition, Spadafore continued, once a new company is acquired, the next question is, When can we get cameras installed? We are quite satisfied with how the IQeye cameras have performed in meeting our sophisticated needs. As a result of using megapixel technology for process control, we have seen improvements in efficiency and productivity and that translates into real money.

New Android Eyes-Free Assistant, Robin, Goes Nationwide, Challenges Siri in the Car


Palo Alto, CA (PRWEB) June 16, 2012

Robin is designed with drivers in mind, aiming to provide them with relevant information, guidance and content via a natural voice / gesture interface. In the car, this interface becomes key, enabling a completely eyes-free interaction: voice in, voice out. Importantly, Robin’s powerful dialogue engine allows a natural and smooth conversation flow, always keeping track of the implied context. Starting a dialogue is as easy as “waving hello” in front of the phone’s screen, so one never has to look away from the road (video).

At the moment, Robin is available in beta across the US, offering features such as local search (including Yelp reviews), navigation, real-time traffic and parking information, gas prices, weather and more. And for those getting bored behind the wheel, Robin can narrate personal Twitter news (with more content reportedly coming soon) and even tell jokes.

According to Magnifis, the company behind Robin, these are just the first steps. Drawing inspiration from the famous KITT of the “Knight Rider” fame, Robin is poised to emerge as a very personal kind of assistant that becomes increasingly helpful as she gets to know her “master” better. For instance, Robin will be able to proactively alert drivers about traffic or speed cameras, based on her knowledge of one’s schedule and driving patterns. And the two-way communication will make it easy for the drivers to share information, e.g., about traffic (Waze style). She will also serve as “personalized radio”, narrating relevant news aggregated from a variety of sources and even learn the individual’s taste in jokes.

“Today, people still think of a car assistant primarily in terms of navigation,” says Magnifis co-founder/CEO Ilya Eckstein. “But in fact, we don’t use navigation much, as most of the time we know our way around. What we really need in the car is someone to watch out for us as we go and be there when we need… well, just about anything. That, and being able to remain fully connected and empowered behind the wheel. To not miss out on a single important bit of life, even when you are not staring at the screen. And that is exactly what Robin is meant to help us with.”
