The webcast shows another cool TV display. This transparent OLED display could for example be used for displaying directions and GPS information to someone driving a car.

The Chip That Designs Itself

The chip that designs itself by Clive Davidson , 1998

Adrian Thompson, who works at the university’s Centre for Computational Neuroscience and Robotics, came up with the idea of self-designing circuits while thinking about building neural network chips. A graduate in microelectronics, he joined the centre four years ago to pursue a PhD in neural networks and robotics.
…
To get the experiment started, he created an initial population of 50 random circuit designs coded as binary strings. The genetic algorithm, running on a standard PC, downloaded each design to the Field Programmable Gate Arrays (FPGA) and tested it with the two tones generated by the PC’s sound card. At first there was almost no evidence of any ability to discriminate between the two tones, so the genetic algorithm simply selected circuits which did not appear to behave entirely randomly. The fittest circuit in the first generation was one that output a steady five-volt signal no matter which tone it heard.

By generation 220 there was some sign of improvement. The fittest circuit could produce an output that mimicked the input – wave forms that corresponded to the 1KHz or 10KHz tones – but not a steady zero or five-volt output.

By generation 650, some evolved circuits gave a steady output to one tone but not the other. It took almost another 1,000 generations to find circuits that could give approximately the right output and another 1,000 to get accurate results. However, there were still some glitches in the results and it took until generation 4,100 for these to disappear. The genetic algorithm was allowed to run for a further 1,000 generations but there were no further changes.

See Adrian Thompson’s home page (Department of Informatics, University of Sussex) for more on evolutionary electronics. Such as Scrubbing away transients and Jiggling around the permanent: Long survival of FPGA systems through evolutionary self-repair:

Mission operation is never interrupted. The repair circuitry is sufficiently small that a pair could mutually repair each other. A minimal evolutionary algorithm is used during permanent fault self-repair. Reliability analysis of the studied case shows the system has a 0.99 probability of surviving 17 times the mean time to local permanent fault arrival. Such a system would be 0.99 probable to survive 100 years with one fault every 6 years.

Very cool.

Federal Circuit Decides Software No Longer Patentable

The Bilski Decision Is In: Buh-Bye [Most] Business Methods Patents

This was an appeal against a rejection of a business methods patent, and the appeals court has now agreed with the rejection. At issue was whether an abstract idea could be eligible for patent protection. The court says no.

Buh-bye business methods patents!

Court Reverses Position on Biz Methods Patents

The ruling in the case, called In re Bilski, largely disavowed the controversial State Street Bank case of 1998. There, the Federal Circuit opened the door to business method patents, which had until then been excluded from patent protection, by granting protection to a system for managing mutual fund accounts. The decision, according to its detractors — which included several members of the Supreme Court — had led to the issuance of weak patents and exposed financial services companies to high-dollar litigation over business method patents.

Patent Gridlock is Blocking Developing Lifesaving Drugs

How patent gridlock is blocking the development of lifesaving drugs by Michael Heller, Forbes

Since a 1980 Supreme Court decision allowing patents on living organisms, 40,000 dna-related patents have been granted. Now picture a drug developer walking into an auditorium filled with dozens of owners of the biotech patents needed to create a potential lifesaving cure. Unless the drugmaker can strike a deal with every person in the room, the new drug won’t be developed.
…
Nicholas Naclerio, who used to head the BioChip Division at Motorola , told Scientific American, “If we want to make a medical diagnostic with 40 genes on it, and 20 companies hold patents on those genes, we may have a big problem.”
…
And it’s not just drugs we’re losing. Today anything high tech–banking, semiconductors, software, telecom–demands the assembly of innumerable patents. Innovation has moved on, but we’re stuck with old-style ownership that’s easy to fragment and hard to put together. This debacle’s only upside is that assembling fragmented property is one of the great entrepreneurial and political opportunities of our era.

This is a critical problem I have written about before. The broken patent system is a serious problem that needs to be fixed.

2008 Lemelson-MIT Prize for Invention

The Lemelson-MIT Prize awards $500,000 to mid-career inventors dedicated to improving our world through technological invention and innovation. Joseph M. DeSimone received the 2008 award.

His exposure to polymer science led him to pursue a Ph.D. in chemistry from Virginia Polytechnic Institute and State University in Blacksburg, Va. At the age of 25, DeSimone joined the University of North Carolina at Chapel Hill (UNC) as an assistant professor in chemistry and launched the university’s polymer program with his mentor Dr. Edward Samulski. He resides there today as the Chancellor’s Eminent Professor of Chemistry at UNC, in addition to serving as the William R. Kenan, Jr. Distinguished Professor of Chemical Engineering at North Carolina State University.

Among DeSimone’s notable inventions is an environmentally friendly manufacturing process that relies on supercritical carbon dioxide instead of water and bio-persistent surfactants (detergents) for the creation of fluoropolymers or high-performance plastics, such as TeflonÂ®. More recently, he worked on a team to design a polymer-based, fully bioabsorbable, drug-eluting stent, which helps keep a blocked blood vessel open after a balloon-angioplasty and is absorbed by the body within 18 months.

DeSimone’s newest invention is PRINTÂ® (Particle Replication in Non-wetting Templates) technology, used to manufacture nanocarriers in medicine. At present, DeSimone’s Lab is vested in a variety of projects that also extend beyond medicine, including potential applications for more efficient solar cells and morphable robots. In 2004, DeSimone co-founded Liquidia Technologies with a team of researchers from UNC to make the technology available in the market. Liquidia is using the PRINT technology to develop precisely engineered nanocarriers for highly targeted delivery of biological and small molecule therapeutics to treat cancer and other diseases. DeSimone’s proposed applications for cancer treatment with the PRINT platform was instrumental in UNC landing a grant of $24 million from the National Cancer Institute to establish the Carolina Center for Cancer Nanotechnology Excellence.

“You can do all the innovating you want in the laboratory, but if you can’t get it out of the university walls you do no one any good,” said DeSimone. He instills an entrepreneurial spirit in his students that focuses on the importance of commercializing technology and scientific inventions. One of DeSimone’s greatest accomplishments is his mentorship of more than 45 postdoctoral research associates, 52 Ph.D. candidates, six M.S. theses and 21 undergraduate researchers. Furthermore, he speaks to groups of high school students about the inventive process and encourages them to learn and explore areas that are less familiar to them to broaden their exposure to other disciplines.

A prolific inventor, DeSimone holds more than 115 issued patents with more than 70 new patent applications pending, and he has published more than 240 peer-reviewed scientific articles.

Transferring Train Passengers Without Stopping

The webcast shows a train transferring passengers without stopping. Essentially passenger modules are picked up and dropped off at each station. Looks pretty cool and would seem to require somewhat complex engineering – which can be a problem as complexity allows for more things to go wrong. Still it looks pretty cool. The sound is not in English but you can see what the idea is.

Inventor rolls out efficient non-stop train system

Taking the Kaohsiung MRT system as an example, Peng says that its maximum speed is 85 kph. Because it must stop at every station, it achieves an average speed over its route of just 35 kph. If the non-stop system were in place, the top velocity of 85 kph could be maintained throughout the system, saving time and energy.

Fold.it – the Protein Folding Game

Foldit is a revolutionary new computer game enabling you to contribute to important scientific research. This is another awesome combination of technology, distributed problem solving, science education…

Essentially the game works by allowing the person to make some decisions then the computer runs through some processes to determine the result of those decisions. It seems the human insight of what might work provides an advantage to computers trying to calculate solutions on their own. Then the results are compared to the other individuals working on the same protein folding problem and the efforts are ranked.

This level of interaction is very cool. SETI@home, Rosetta@home and the like are useful tools to tap the computing resources of millions on the internet. But the use of human expertise really makes fold.it special. And you can’t help but learn by playing. In addition, if you are successful you can gain some scientific credit for your participation in new discoveries.

The site includes some excellent educational material on proteins and related material. What is a protein:

Proteins are the workhorses in every cell of every living thing. Your body is made up of trillions of cells, of all different kinds: muscle cells, brain cells, blood cells, and more. Inside those cells, proteins are allowing your body to do what it does: break down food to power your muscles, send signals through your brain that control the body, and transport nutrients through your blood. Proteins come in thousands of different varieties, but they all have a lot in common. For instance, they’re made of the same stuff: every protein consists of a long chain of joined-together amino acids.
…
structure specifies the function of the protein. For example, a protein that breaks down glucose so the cell can use the energy stored in the sugar will have a shape that recognizes the glucose and binds to it (like a lock and key) and chemically reactive amino acids that will react with the glucose and break it down to release the energy.
…
Proteins are involved in almost all of the processes going on inside your body: they break down food to power your muscles, send signals through your brain that control the body, and transport nutrients through your blood. Many proteins act as enzymes, meaning they catalyze (speed up) chemical reactions that wouldn’t take place otherwise. But other proteins power muscle contractions, or act as chemical messages inside the body, or hundreds of other things.

Physicist Swimming Revolution

A Revolution That Began With a Kick by Amy Shipley:

The answer, they say, cannot lie solely in the latest high-tech swimsuits introduced amid a swirl of controversy this winter, because the world-record smashing began at last year’s world championships — long before the newest of the newfangled apparel came out.

Swimmers, coaches and scientists say it is impossible to pinpoint one explanation. They cite many contributing factors, ranging from professional training groups that have sprouted across the United States to greater access to underwater cameras and other advanced technology.

But some say the most significant breakthrough has been a revival of a swimming maneuver developed more than 70 years ago by one of the physicists who worked on the atomic bomb.

Though utilized for decades, the underwater dolphin kick had not been fully exploited by the swimming mainstream until Olympic megastar Michael Phelps and a few other stars began polishing it — and crushing other swimmers with it — in recent years.

Very interesting and another example of how good ideas are often ignored for a long time.

The underwater dolphin kick attracted the interest of swimming innovators as early as the 1930s. The late Volney C. Wilson explored its possibilities before diving into later work on nuclear fission and the atomic bomb, according to David Schrader, a research professor at Marquette University who is Wilson’s biographer.

Schrader said Wilson, an alternate on the 1932 Olympic water polo team who studied fish propulsion at a Chicago aquarium, claimed to have shown the kick to Johnny Weissmuller, a training mate at the Illinois Athletic Club. “Weissmuller reproduced it perfectly, but was not impressed by it,” said Schrader in a phone interview, recalling a conversation with Wilson.
…
One of the first swimmers to turn heads with the underwater dolphin kick was David Berkoff, a Harvard graduate who became known for the “Berkoff Blastoff.” In 1988, Berkoff set several world records in the 100 backstroke by dolphin-kicking for 35 meters underwater at the start of the race.

Which goes to show you that you can gain advantages just by using the information that is available – your own innovation is not the only way to get ahead. Just doing a better job of adapting what others learn to your challenges can be very rewarding.

Cloak of Silence

Experts unveil ‘cloak of silence’

“The mathematics behind cloaking has been known for several years,” said Professor John Pendry of Imperial College London, UK, an expert in cloaking. “What hasn’t been available for sound is the sort of materials you need to build a cloak out of.”
…
The Spanish team who conducted the new work believe the key to a practical device are so-called “sonic crystals”. These artificial composites – also known as “meta-materials” – can be engineered to produce specific acoustical effects.
…
The research builds on work by scientists from Duke University in North Carolina, US, and the Hong Kong University of Science and Technology. Earlier this year, independent teams from the two institutions demonstrated the mathematics necessary to create an acoustic cloak. Other scientists have shown that objects can be cloaked from electromagnetic radiation, such as microwaves.

Pax Scientific

Nature Gave Him a Blueprint, but Not Overnight Success

Mr. Harman is a practitioner of biomimicry, a growing movement of the industrial-design field. Eleven years ago, he established Pax Scientific to commercialize his ideas, thinking that it would take only a couple of years to convince companies that they could increase efficiency, lower noise or create entirely new categories of products by following his approach.
…
His radical ideas have so far found a cautious reception in the aircraft, air- conditioning, boating, pump and wind turbine industries. Mr. Harman’s experience is not unusual. Rather than beating a path to the door of mousetrap designers, the world seems to actively avoid them.
…
Even in fields such as the computer industry, which celebrates innovation, systemic change can be glacial.
…
In another hopeful sign, a world that long ignored energy efficiency is suddenly thinking of nothing else. “We tried for years to promote energy conservation, and we couldn’t find one who was interested,” he said. “Now the world has done a U-turn.”

Yet another example that new knowledge is not enough. It takes much longer for good ideas to be put into practice than seems reasonable (until you get your head around the idea it takes a fair amount of time for new ideas to be adopted).

One positive aspect of this reality is that if you can take advantage of new ideas before others you can gain an advantage. It isn’t necessarily true that just because now everyone knows about some new idea that you have no opportunity to use the knowledge before others.
