BCS Title Game, Live in 3D

BCS title game to be available live in 3-D

Thanks to an impressive — though not glitch-free — test broadcast of an NFL game two weeks ago, Burbank, Calif.-based 3Ality Digital said Tuesday it had won the contract to shoot the Jan. 8 BCS National Championship game in 3-D.

The game between Florida and Oklahoma will be broadcast live in 3-D to 80 to 100 movie theaters in about 30 U.S. cities, said 3Ality Chairman David Modell. Tickets are expected to cost $18 to $22, said Cinedigm Digital Cinema Corp., which is working with 3Ality to deliver the broadcasts to theaters.

“The live broadcast to the Paris Hotel and to movie theaters across the nation is the latest example of how we can deliver our programming to audiences in new and exciting ways,” said Jerry Steinberg, senior vice president of field operations and engineering for FOX Sports. “3D technology holds unlimited potential for the future of both sports broadcasting and live event production.”

Cool, though not quite the holographic TV I am still waiting for.

Friday Cat Fun #8: Cat Ridding a Roomba

This cat seems to enjoy the ride as a Roomba vacuums. My cat would always go crazy when the vacuum cleaner went on.

Buy a Roomba for your cat to ride. Or get your cat a camera and put their photography online. You can also shop for people with our selection of some science and engineering gadgets and gifts.

Black and Decker Codeless Lawn Mower Review

My old version of this mower just stopped working and the repair guy said it would cost $250 for a new starter, new battery… So I bought a new one: Black & Decker 19-Inch 24-Volt Cordless Electric Mulching Lawn Mower #CMM1200. He said that the new ones were not as well manufactured. I couldn’t imagine how you could make things worse (it is a simple product and just adopting improvement over the years should be really easy).

But, the starter on this model is horrible. You have to tun this incredibly cheap key in a very poorly designed socket. Fails over 80% of the time. The old model started easily essentially every time. The design was just as you would expect, foolproof. Whatever pointy haired boss approved this design needs to go into another line of work.

The ability of the mower to cope with high grass is very poor – much worse than the previous model. I had a good test at first given the time between my mower breaking and getting the new one. Not often an issue, but still not a good thing.

They had a poor indication of the charge left in the battery previously. They now provide no indication of the charge left. It makes you realize that a poor indication was much better than none.

Battery technology has improved a great deal, and that was one of biggest the weaknesses of the last one. Well they seem to have managed to provide worse battery performance after 5 years of improvement in that technology. Pretty sad.

The bag design is much better than the previous model. You have to assemble it yourself but it is much more sturdy and much better designed – you can replace the fabric and keep the frame. The old model the entire things needed to be replaced if the fabric broke. And given the flimsy design mine broke very early on.

Dean Kamen: Stirling Engines

Dean Kamen: part man, part machine

Conceived in Scotland almost 200 years ago, the Stirling [engine] is a marvel of thermo-dynamics that could help to replace the internal combustion engine – in theory it can turn any source of heat into electricity, in silence and with 100 per cent efficiency. But corporations including Phillips, Ford and Nasa have devoted decades of research, and millions of dollars, to developing the engine, and all retired defeated, having failed to find a way of turning the theoretical principles of the engine into a workable everyday application. Kamen, nevertheless, has spent the past 10 years and, he estimates, up to $40 million working on the problem.

Now he and his engineers have built and tested a range of Stirling engines suitable for mass production that can be run on anything from jet fuel to cow dung. The one in the boot of the small blue car is designed to extend its range and constantly recharge its batteries to make a new kind of hybrid vehicle: one fit for the roads of the 21st century. A Stirling-electric hybrid, Kamen tells me, can travel farther and more efficiently than conventional electric cars; it generates enough power to run energy-hungry devices such as heaters and defrosters that are essential for drivers who, unlike those he calls the ‘tofu heads’ of California, must cope with a cold climate; and even using petrol, the engine runs far cleaner than petrol-electric hybrids such as Toyota’s Prius.

However, Kamen confesses, his new creation isn’t quite finished yet: ‘The Stirling engine’s not hooked up. Which really pisses me off.’

But it could work?

‘It will work,’ he says. ‘Trust me.’

Holographic Television on the Way

Ok, there really isn’t much new since I posted that holographic TV is getting closer. But won’t it be cool when I can have one in my house? And you might need to plan for it in your new house addition 🙂 Also, with the economic news lately a good distraction might be useful – Holographic television to become reality

The reason for renewed optimism in three-dimensional technology is a breakthrough in rewritable and erasable holographic systems made earlier this year by researchers at the University of Arizona.

Dr Nasser Peyghambarian, chair of photonics and lasers at the university’s Optical Sciences department, told CNN that scientists have broken a barrier by making the first updatable three-dimensional displays with memory.

“This is a prerequisite for any type of moving holographic technology. The way it works presently is not suitable for 3-D images,” he said. The researchers produced displays that can be erased and rewritten in a matter of minutes.
…
According to Peyghambarian, they could be constructed as a screen on the wall (like flat panel displays) that shows 3-D images, with all the image writing lasers behind the wall; or it could be like a horizontal panel on a table with holographic writing apparatus underneath.
…
Peyghambarian is also optimistic that the technology could reach the market within five to ten years. He said progress towards a final product should be made much more quickly now that a rewriting method had been found.

However, it is fair to say not everyone is as positive about this prospect as Peyghambarian. Justin Lawrence, a lecturer in Electronic Engineering at Bangor University in Wales, told CNN that small steps are being made on technology like 3-D holograms, but, he can’t see it being ready for the market in the next ten years.

I would have to say I am with those that think this might take a bit longer to be in place. But I would be glad to be wrong.

The Glove – Engineering Coolness

Cool invention helps tired players bounce back

The device, called the Glove and invented by two Stanford biologists, is used by the Niners during games and at practice for players’ health. But its applications are far broader: from treating stroke and heart attack victims to allowing soldiers to remain in the field longer under intense heat.

It’s also a proven athletic performance enhancer – billed as better than steroids without any ill effects.

“We use the Glove primarily for health reasons,” said Dan Garza, the 49ers’ medical director. “But outside of sports, it has potential for a lot of exciting things. This technology is a much more effective way of cooling the core temperature than what we would typically do – misting, fanning, cold towels, fluids.”

The Glove works by cooling the body from inside out, rather than conventional approaches that cool from outside in. The device creates an airtight seal around the wrist, pulls blood into the palm of the hand and cools it before returning it to the heart and to overheated muscles and organs. The palm is the ideal place for rapid cooling because blood flow increases to the hands (and feet and face) as body temperature rises.

“These are natural mammalian radiators,” said Dennis Grahn, who invented the device with Stanford colleague Craig Heller.

Cool, you can buy your own for only $2,000 🙂 (The Glove used to be called Core Control) High resolution image. Related: Research on Reducing Hamstring Injuries – The Science of the Football Swerve – Randomization in Sports – posts on science and athletics

Toyota Engineering Development Process

Kenji Hiranabe talks about Toyota’s development process (webcast). Kenji shares a presentation he attended earlier this year by Nobuaki Katayama, a former Chief Engineer at Toyota, and the lessons he learned from him.

The webcast takes awhile to get going. If you are impatient you might want to start at the 6 minute mark. Some thoughts from the talk:

The Voice of the Customer is diffuse. A strong concept (for a project – new car for example) is very important to focus thought, listening to voice of the customer is important but must use strong concept to avoid losing focus (due to diffuse customer feedback).
Honest face to face communication is important. Bad news first – present bad news first [don’t try to hide bad news – my thoughts in brackets, John Hunter].
Everyone must think about cost reduction, many efforts add up to big impact [the importance of reducing waste everywhere].
benchmark, not to copy others, but to learn from what others do well.

The webcast includes a nice (though short) discussion of agile management in software development and lean manufacturing (the different situation of manufacturing versus software development). Kenji Hiranabe has also translated several agile and lean books into Japanese including Implementing Lean Software Development.

15 Photovoltaics Solar Power Innovations

15 Photovoltaics Solar Power Innovations You Must See

Researchers at McMaster University (coolest name ever) have succeeded in ‘growing’ light-absorbing nanowires made of high-performance photovoltaic materials on carbon-nanotube fabric. In other words, hairy solar panels.

The aim is to produce flexible, affordable solar cells that, within five years, will achieve a conversion efficiency of 20%. Longer term, it’s theoretically possible to achieve 40% efficiency!
…
while looking for a solution, researchers noticed that moths have very non-reflective eyes (“most likely an evolutionary defense against nocturnal predators”). The moth-eye process creates panels that reflect less than 2% of light. That’s a vast improvement over the 35 to 40% reflection rate seen without the anti-reflection coating layers.
…
Some experts are speculating that First Solar might beat over 80 competitors to achieve manufacturing costs low enough to market solar panels at less than $1 per Watt, the target considered necessary for solar to compete with coal-burning electricity on the grid.

Saving Lives with Smarter Hurricane Evacuations

Software developed by a MIT student is aiding emergency officials as they decide on evacuation plans:
Saving lives through smarter hurricane evacuations

Michael Metzger’s software tool, created as part of the research for his PhD dissertation, could allow emergency managers to better decide early on whether and when to order evacuations — and, crucially, to do so more efficiently by clearing out people in stages. The tool could also help planners optimize the location of relief supplies before a hurricane hits.
…
“All in all, this is a complex balancing act,” Metzger says.

The concept of evacuating an area in stages — focusing on different categories of people rather than different geographical locations — is one of the major innovations to come out of Metzger’s work, since congestion on evacuation routes has been a significant problem in some cases, such as hurricanes Katrina and Rita. Metzger suggests that, for example, the elderly might be evacuated first, followed by tourists, families with children, and then the remaining population. The determination of the specific categories and their sequence could be determined based on the demographics of the particular area.

By spacing out the evacuation of different groups over a period of about two days, he says, the process would be more efficient, while many traditional systems of evacuating a given location all at once can and have caused serious congestion problems.
….
Other factors that could help to make evacuations more effective, he says, include better planning in the preparation of places for evacuees to go to, making sure buses and other transportation are ready to transport people, and preparing supplies in advance at those locations.

Toyota Winglet – Personal Transportation

Winglet Personal Mobility Device from Toyota

Toyota has a long term vision. The population of Japan is aging rapidly. Toyota has invested in personal transportation and personal robotic assistance for quite some time. I must admit this new Winglet doesn’t seem like an incredible breakthrough to me (their earlier iUnit seems much better to me – though I am sure much more expensive too). The interest to me is in their continued focus on this market which I think is a smart move. The aging population worldwide (and others) will benefit greatly from improved personal mechanical assistance.

The Winglet is one of Toyota’s people-assisting Toyota Partner Robots. Designed to contribute to society by helping people enjoy a safe and fully mobile life, the Winglet is a compact next-generation everyday transport tool that offers advanced ease of use and expands the user’s range of mobility.

The Winglet consists of a body that houses an electric motor, two wheels and internal sensors that constantly monitor the user’s position and make adjustments in power to ensure stability. Meanwhile, a unique parallel link mechanism allows the rider to go forward, backward and turn simply by shifting body weight, making the vehicle safe and useful even in tight spaces or crowded environments.

Toyota plans various technical and consumer trials to gain feedback during the Winglet’s lead-up to practical use. Practical tests of its utility as a mobility tool are planned to begin in Autumn 2008 at Central Japan International Airport (Centrair) near Nagoya, and Laguna Gamagori, a seaside marine resort complex in Aichi Prefecture. Testing of its usefulness in crowded and other conditions, and how non-users react to the device, is to be carried out in 2009 at the Tressa Yokohama shopping complex in Yokohama City.

Toyota is pursuing sustainability in research and development, manufacturing and social contribution as part of its concept to realize “sustainability in three areas” and to help contribute to the health and comfort of future society. Toyota Partner Robot development is being carried out with this in mind and applies Toyota’s approach to monozukuri (“making things”), which includes its mobility, production and other technologies.

Toyota aims to realize the practical use of Toyota Partner Robots in the early 2010s.

On a personal note, I bought some more Toyota stock last week. The stock has declined a bit recently. Toyota is one of the companies in my 12 stocks for 10 years portfolio.
