US hits Islamist group in Mali with sanctions
Friday - 12/7/2012, 10:18am EST
By MATTHEW LEE
Associated Press
WASHINGTON (AP) - The Obama administration is imposing sanctions on a radical, Mali-based Islamist group and two of its top leaders.
The State Department and the Treasury on Friday blacklisted the Movement for Unity and Jihad in West Africa as a specially designated foreign terrorist group, which freezes any assets its members may have in U.S. jurisdictions and bans Americans from doing business with them. The designation also applies to the group's two main founders, Hamad el Khairy, and Ahmed el Tilemsi.
The group was created in September 2011 as an offshoot of Al-Qaida in the Islamic Maghreb and is accused of numerous terrorist attacks and kidnappings of aid workers and diplomats in northern Mali and Algeria.

Bank-Liquidity Supervision Sparks U.K. Clash With EU
Dec. 1 (Bloomberg) -- The U.K. is clashing with European Union authorities over its right to police the liquidity of London branches of foreign lenders in the wake of the collapse of Iceland's banking system.
The European Commission is proposing to shift powers for regulating bank branches' liquidity away from authorities where they are located to the lender's home nation. The U.K. is concerned that this could leave its regulators unable to protect British depositors in a crisis.
Britain is calling for "appropriate safeguards for host supervisors to ensure financial stability in their jurisdiction," the U.K. Treasury said in an e-mailed statement. The U.K. is "working closely" with the commission and other governments "to achieve this goal."
Regulators are seeking ways to prevent a repeat of events in 2008 when depositors in the U.K and the Netherlands lost money with branches of failed lender Landsbanki Islands hf. The Netherlands, U.K., and Iceland have struggled to agree on repayment terms for the $5.2 billion needed to cover the depositor losses.
The U.K has support from central and eastern Europe for allowing host country regulators to retain emergency powers over foreign branches' liquidity, restricting their ability to shift money and take deposits.
The commission says responsibility for policing liquidity is best concentrated with a bank's main supervisor.
Appropriate Control
Michel Barnier, the EU's financial services commissioner, favors measures to "align" supervision of liquidity with that of capital, said Chantal Hughes, his spokeswoman at the Brussels-based commission. Host supervisors would be left with "appropriate control."
Lenders "generally support" the commission approach, the European Banking Federation said in an e-mailed statement. Reporting "to the home supervisor rather than to all countries where it has a presence," would reduce the burden on lenders, it said.
"Whenever host supervisors become too proactive, I think it can actually have a negative effect on the real or perceived stability of a group by locking in liquidity in branches," said Anders Kvist, head of group treasury at Sweden's SEB AB bank.
SEB has 193 branches in Estonia, Latvia and Lithuania, according to information on the company's website.
"The concerns of host regulators are understandable but sound branch liquidity management can be best achieved by harnessing the group's strength," Kvist said.

Gear Question
Has anyone compared it with f1lite farola...
Has anyone compared it with f1lite farola from Coleman? I Think self ignition is a waste of weight as you can use your ignition steel.
The 70W illumination on this lantern is a stretch. It's more like 40W, very similar to the F1. They use virtually the same mantle & therefore have the same output. I agree with you on the piezo. The extra weight isn't justified making the Primus slightly heavier.

Northwest Environmental Defense Center (NEDC)
About NEDC
Organizational Structure
NEDC is a non-profit, tax-exempt 501(c)(3) organization. In addition to their dedication to the protection of the environment and natural resources of the Pacific Northwest, NEDC's Board of Directors bring a wide range of experience and knowledge to the organization. While many members of the Board of Directors, including the President, are practicing attorneys, there are always several student board members who bring unique perspectives to the Board.
The NEDC staff is comprised of an Executive Director, two Staff Attorneys, and a Law Clerk who manage the daily obligations of the organization. The strength of the organization, however, is the student volunteers. NEDC students currently work as members of one or more of our project groups, including: Lands and Wildlife, Water, Air, and Sustainable Agriculture. The groups are coordinated by Project Group Coordinators who are responsible for evaluating notices of proposed agency actions and requests for assistance from other environmental groups to determine whether NEDC should be involved in a given project. Project Group Coordinators then discuss potential projects with student volunteers, allocate project assignments based on student interest as well as board member priorities, and work with students on projects.
NEDC Staff:
Mark Riskedahl, Executive Director
Mark grew up in a little house on the prairie in rural North Dakota. He received a B.A. from the University of Minnesota and his J.D. from Lewis and Clark Law School. Before attending law school, Mark worked in the social services, primarily with people dealing with autism. During law school, Mark worked as the NEDC Law Clerk, a Project Coordinator, and Student Director. Following graduation, Mark helped institutionalize NEDC's influence on the Pacific Northwest by creating the Executive Director position. Since that time NEDC has grown to a staff of four, with a broad number of student volunteers and hundreds of members and supporters across the country.
Andrew Hawley, Staff Attorney
Andrew is from Valley Forge, Pennsylvania. Andrew earned his law degree in 2003 from Lewis and Clark Law School. At Lewis and Clark, he volunteered with the Public Interest Law Project and worked for the Northwest Environmental Advocates and Defenders of Wildlife. Andrew was a clinical student with the Earthrise Law Center. Before coming to NEDC in 2008, Andrew worked for Defenders of Wildlife in Washington, DC. Bar Admissions: Oregon, California, and District of Columbia. Court Admissions: U.S. Supreme Court, U.S. Court of Appeals for the District of Columbia, U.S. District Court for the District of Oregon, U.S. District Court for the Northern District of California.
Marla Nelson, Staff Attorney
Marla relocated to the West coast from Minnesota. She earned a Bachelor's degree in Spanish and Biology from St. Olaf College in Minnesota and her J.D. from Lewis and Clark Law School in 2012. Prior to law school, Marla spent one year teaching English in Japan and two years doing grants and contracts work with a nonprofit foundation in Minneapolis. During law school Marla worked as the NEDC Law Clerk and Student Co-Director, competed on Lewis and Clark's National Environmental Moot Court Team, interned with Earthjustice's California regional office, and was a clinical student with Earthrise Law Center. Marla joined NEDC in September, 2012 as a Legal Fellow and became a Staff Attorney in 2014. Bar Admissions: Oregon, Washington. Court Admissions: U.S. District Court for the Eastern District of Washington, U.S. District Court for the District of Oregon.
Becca Fischer, Law Clerk
Becca grew up on the edge of the Great Plains in Billings, Montana. She learned to love the lush, green beauty of Oregon while earning her degree in Environmental Science from Willamette University in Salem, Oregon in 2007. Upon graduation, Becca returned to Montana to work for an environmental non-profit organization. There, she learned about the importance of clean water and the need to protect our water from dirty energies such as coal mining and oil and gas. This exposure to grassroots organizing further strengthened her desire to be a lifelong environmental activist. As a result, Becca began her studies at Lewis and Clark Law School in 2013. In her first year, she was involved with NEDC as a volunteer in its Water Group and as a Student Board Member. Becca is continuing her work with NEDC as the 2014-15 Law Clerk.

The Mets have homered in all 11 games in which they have played.
The previous team record for consecutive games with a home run to start the season was eight, set in 1987.
Two weeks into the season, the Mets stand at 7-4, good enough for second place in the NL East. They are just half a game ahead of the Nationals and three and a half behind the Braves.
Catcher John Buck, in his first year with the ball club, has contributed with a home run in six of these games, including a stretch of four straight. Buck has driven in a major league-leading 19 runs, tied with Baltimore's Chris Davis and Detroit's Prince Fielder, and has five more runs-batted-in than the next highest National League player, Brandon Phillips of the Reds.
Long balls haven't been the only source of offense for this Mets team, however. Infielder Daniel Murphy has 16 hits in 42 at-bats, good for a .381 batting average, to go along with his team-high 10 runs scored. While Lucas Duda and captain David Wright are hitting under the .300 mark, both have gotten on base more than 40% of the time.
There are several players who have not been producing at a very high level, though. Ruben Tejada, Collin Cowgill, Ike Davis and Kirk Nieuwenhuis have combined for a mere 21 hits in 116 at-bats.
Even still, the Mets offense, as a whole, has been much better than expected, plating double-digit runs in two of their 11 games.
While the offense has been surprisingly explosive, the real story so far has been the dominance of pitcher Matt Harvey.
In three starts, the second year phenom owns a 0.82 ERA and a 0.55 WHIP, with 25 strikeouts in 22 innings pitched.
In his most recent outing, Harvey took a no-hit bid into the seventh inning. He surrendered one earned run on two hits, striking out six Minnesota Twins in eight innings-- the longest start of his career.
Jon Niese has also impressed in his three starts, but the rest of the starting rotation has been disappointing, and the bullpen has, for the most part, been pretty solid. Bobby Parnell successfully closed out the one save opportunity he has been faced with.
After winning three of their first four series', the Mets are definitely giving fans reason to be excited, especially if Harvey continues to develop into a legitimate ace and the offense continues its home run-hitting pace.
After being snowed out of the final game against the Twins on Sunday, the Mets head to Colorado to face the Rockies for four games, where it is expected to snow, as well.

Re: Gluing Pedestal Guard Feet???
I did this exact project 5 years ago. The pedestal guard legs insertsinto the chrome feet which have a rubber gasket and a large heavy washers and have two substantial 3-4 inch long (1/2 inch diameter bolts). You must put the washers ( I added a backing plate too) under the cockpit sole then the rubber on top of the sole then the chrome feet holder. Just gluing with 5200 will not withstand the stress of pressure you will torque the guard with either holding on to it or falling against it. The backing plate will spread the stress. In my install I actually used the tubes to lead down all my wires from the two nav pods I have which have Chartplotter and radar cables. I drilled holes for the bolts as well as for the cables. If you have core you have to gouge it out and fill with epoxy so there is no water intrusion in the core of the cockpit sole.

R.K. Raghavan is elated at being recommended by the Board of Control for Cricket in India (BCCI) to the Supreme Court as part of the three-member panel that will probe into betting and spot-fixing allegations in IPL-6.
Speaking to The Hindu, the former CBI Director, said here on Monday, "I am delighted at the opportunity to do my bit for cricket, Supreme Court permitting. And I do not bow down to flimsy and frivolous charges made against me by some."
He was reacting to a tweet by former IPL Commissioner Lalit Modi that said there was a conflict of interest in Raghavan's case since he was the secretary of Kamyuth Club, which plays in the TNCA league here.
The 73-year-old former CBI boss said, "The club is owned by my brother-in-law. Since he lives in Bangalore and cannot oversee the affairs of the club, he asked me to manage it. Still, I am not actively involved with the club. I have not attended the general body meetings of the TNCA for quite some time. And I have scrupulously kept away from holding any post in the TNCA."Disclosure
Raghavan revealed that when Justice Mudgal met him recently, he had informed him of his involvement with Kamyuth.
"That was the first statement I made to him, that my family was involved with a club that plays in the TNCA league. I did not want to suppress any information from him. My integrity has never been questioned."
The septuagenarian has been associated with cricket at various levels. "I have played in the second division league here for the Royapettah Club. Then I have umpired in the first division league. I have been a radio and television commentator during the Ranji and Duleep Trophy matches."
Crucially, he headed the CBI that probed the match-fixing scandal of 2000. "That report was hard-hitting. And the subsequent stringent action taken by the BCCI endorsed the CBI report," Raghavan said.
He added, "I am a lover and a fan of the game. I do not want any publicity. I have seen enough photographs of myself in the media. It's just that I am keen to give something back to the game that has provided me so much joy."
Asked how he would look at the IPL probe, Raghavan replied, "Let me cross the bridge when it comes."

I'm looking for a full size tower case. Budget is not much of a consideration but I don't really want to get into the Cosmos II range either. I'm looking for something with good air cooling--preferably with large quiet fans.
I'm leaning toward the CM Strorm Stryker but would love to hear about your personal favorites.

I am not keen on cases which position power supplies to blow hot air onto the CPU, or the GPU in the case linked above. It just seems like an oversight in design that has been accepted for too long. My current PC was custom-built inside of a Pelican Case. The air flow is designed to remove heat from the case for each of the major heat-generating components. This is achieved with only two case fans - one for the GPU and one for the CPU. The power supply's fan points toward the exterior of the case instead of toward the CPU. Air vent holes are large, but positioned so air flows across the intended parts to be cooled before exiting.
If you find a case with well-thought-out cooling, let me know. My Pelican Case idea was mostly for travel, but the weight and size make it only suitable for road-trips. I could use just about any computer case for that.

I used to use full tower cases but have switched over to mid tower for both my PCs.
With a case as big as the one you linked air flow wont be an issue, neither will it matter where the PSU is. Which from the pics it is in pretty much the standard place in a case.
If you are just putting together a regular gaming rig. I.E. One GPU, Air cooled CPU, ect then you wont have any issues at all with cooling by using the fans that come with the case. If you are doing an sli / xfire setup with high end GPUs, high end liquid cooling, ect. then you may have to put a little thought into it.
A case that big is really made for very high end rigs that need alot of airflow, fans, ect to disperse a large amount of heat. For most people a mid tower case with thought out fan placement is more than enough.
I have and I5 2500k oc to 4.4, a 7870 OCd , SSD, 2x 2tb HDD, 16gb RAM, Corsair H60 cpu cooling, Seasonic 550w psu, ect in my mid tower case with 3 fans. My temps stay fine even under heavy gaming load for hours and hours. Plus it does not weigh 40 pounds and serve as a desk when not in use.
If you have used full tower cases in the past you know what to expect. If you have not then you may want to consider a really good mid tower unless your building an uber rig.
Just my 2cp
With a full tower, as far as cooling goes, it will be hard to go wrong. If the case doesn't have fans stock, it's a simple matter of adding them where you want them (and fans are cheap, $15 for a very good one, $5 for a cheap one).
I am personally a Lian Li fan. They are pricey compared to some of the competition, but I appreciate their clean no-frills designs, the well-thought out interiors, and the all aluminum chassis is sturdy, light, and easy to mod.
Really, though, it comes down to aesthetics with a full tower. Whatever looks good to you - they are all going to perform more or less the same because you'll have so much empty space, even if you are doing 3xSLI or something that requires a lot of space. Full sized towers are ~big~.
Power supplies blow outward. They pull air from inside the case, which aids in overall cooling of the CPU/GPU.
Once upon a time power supplies blew inward, way back in the original ATX standard (1995), when they thought they could get away with using the PSU fan for the CPU heatsink, and the CPU wouldn't require it's own fan. Once CPU's started requiring their own fans, it became a better idea to use the PSU to exhaust that heat out, rather than blow already warm air on the CPU, and ATX PSU manufacturers started to change back in the late 1990's.
So no matter where you position your power supply, unless you install it backwards, it won't blow hot air onto a CPU or GPU. It will pull hot air out.
While there is certainly nothing wrong with the CM Storm Stryker I'm going to assume you choose it either based on looks and/or popularity of the model/brand.
Might I suggest if money really isn't an issue (up to a certain point of course) that you look into getting a quality Aluminum case such as those available from Silverstone or Lian-Li. There is also Caselabs which if I were looking into full tower would probably be my first choice. They are hard to beat but will cost you a pretty penny, then again you do get what you pay for and can be customized to meet just about EVERY possible need through available additional parts.
Unless you have a very specific need or desire to have a full tower my recommendation for Air Cooling would be Silverstones Fortress (all aluminum, subdued look, called FT for short) or Raven line-up (mixed material, more drastic in appearance, called RV for short). They are basically the same thing from an internal perspective and only differ slightly in outer appearance and construction material, which of course comes back to price as well. They work of a direct air flow concept where by the "wind tunnel" never has to bend like in normal tower setups. The 180mm fans that come with them are top of the line too and pretty quiet for the most part.

This case is really good, lots of room, nice air flow with big fans. Only draw back is it can get dusty in it faster than a normal case.
Also, this is a link to tigerdirect, you might be able to find it cheaper in other places.

My current rig is the first full tower build I have done and I love it. Maximum air flow and just looks beastly. My case is related to the one you linked.

Yeah I actually prefer black also so I've been looking at the Trooper too. The main difference with the Stryker that has me leanig that way is the extra "bulge" on the right hand panel that gives you a bit more room for the cables. Either one is great though. Love the hot-swapable 2.5" drive slot, fan controller, that lovely storage box at the bottom front and all the attention to detail.
I'm curious. Did you move the HD cage fans to the more conventional front to push air at the GPU or left them on the side for tidier cabling?
And the rest of you... thanks for all the suggestions. I've spent several hours following your links and reading reviews :)
If you seem set on the CM Storm Stryker or Trooper I'd highly suggest you check on Tiny Tom Logans review of each and his comparison vidoes on youtube. He's a very reputable and thorough reviewer from Great Britain who typically gets first hands on review of hardware within Europe because of it. The vidoes are LONG but that is only because he is raw (for a computer hardware reviewer that is) and tends to touch a MANY areas other reviewers leave out. Well worth your time as he actually chose the Storm Stryker for a sentimental/tribute build OVER what some would have considered a higher quality Caselabs case and explains why. That build in question and the video related to it is titled "Orca".

If you don't have much of a budget, get a Rosewill case. They are cheap and amazing.

Yeah I had already seen Tiny Tom's Stryker video review. But I hadn't seen his custom Orca job... very nice!
I like his reviews a lot--he's very conscientious and a good communicator to boot. "Thorough" is almost an understatement for his reviews
Another case that has caught my eye (which Tom has only "previewed" so far is the new Corsair 350D - a very interesting "double-wide" design that hides the PSU and HD bays behind the motherboard: https://www.youtube.com/watch?v=OPBVBzviVwQ&list=SPBDE3358367DB7324&index=2
Some might say I'm obsessing too much over the case decision... I think of it more as fully savoring the planning stages--especially so since most other components for my build are pretty well decided already (see below.)
Most of the rest of my build is decided: I'm keeping my ATI 7970 GPU (of course), my two SSDs, 1TB WD drive, Noctua NH-D14 cooler and Corsair 1000W PSU.
The CPU will be either the i5 4670K or i7 4770K...still pondering how much my Photoshop and Premiere work will benefit from the i7. For gaming, either is great. Whichever one it is, the plan is to OC it to ~ 4.5 Ghz rate.
The MB will be one of the ASUs z87s...one that OC's well and easily...and, this time, looks good also.... not sure which yet. I've been using ASUS MBs almost exclusively for 20 years...I trust them.
I'll probably add another HD-- a 3TB Seagate... 18 MPixel cameras make large RAW files :)
And I'm getting new RAM - 16GB (2X 8Gb) of Corsair Vengeance pro (Noctua height compatible.) I currently have 3X 2GB on my old triple-channel ASUS.
I originally thought of going with a sealed WC kit, probably the Corsair H100i, but the differences in performance between it and the Noctua are minimal and the Corsair is noisier too. Pretty well ruled that out.

If you check the pics under my profile you will see my wife's system which she uses for Photoshop and gaming. Most edits are done in a matter of seconds and it's an i5. I can't claim one way or another whether or not you will see a noticeable improvement by jumping to an i7 because we don't currently own one but would you really need something to be faster than a few seconds anyway?
Well I went for the Stryker after all. I saw one in person and it was nerd-love at first sight
I've already started the build: got the MB, CPU, RAM, 1 SSD and my new HD in there all nicely connected and cable managed,
For the motherboard I didn't go with an ASUS after all (gasp! I feel like a heretic). The more I read and saw of the MSI Z87-GD65, the better it looked. It also happens to be a black MB with some red accents that actually looks great with the black and white Stryker theme.
I went with the i7-4770k after all. I'm not saying it's better for gaming than the i5 equivalent but I happened to be flush with my old tax return check that's been burning a hole in pocket for a while... so why not?
For the ram I went with 2 X 8GB of G-skill Trident X 2400-CL10.... not because of the 2400 CL10 but because I've seen several reports of it running at CL 6 or 7 and 1T @ 1866. That's what I'll be shooting for anyway. It doesn't hurt that they're black with red accents just like the MB :) And yes I know, 16 GB is also overkill for gaming. At least I'll see an occasional use for the extra ram when I'm doing some fancy edits of large 18 Mpixel RAW files in Photoshop.
I'll probably finish the build today or tomorrow and I'll post some photos when I'm done. It's the best looking build I've ever done... but then, I've never gone for looks before... I feel shallow :)
Been meaning to finish off this thread with some photos of the build. So here they are. It's probably the best cable management job I've done...if I say so myself :)
There are larger versions of the photos in my gallery here. Just click my name if you want to see them larger.
Looks very nice. Great job!

When performing at top load (70-100% but that hardly happens) the GPUs are still 5 degrees Celsius cooler than normal. Reason is that the PSU (though blowing warm air) makes a forced airflow upward to the back fan that takes the warm air it out...
@OP If you're planning on going SLI/XFIRE I'd advice the one you're using ;)
See you already got one... Whenever you get heath problems (doubt it in your setup) turn the PSU fan up ;)

Black Friday
A brutal beating, caught-on-camera, happened inside Westfield Annapolis Mall on Black Friday. Now, police are stepping in after a victim came forward. WJZ-TV's Mike Hellgren reports on what happened and the startling video.
----- 000 9 Ridiculous Toy Fails To Avoid On Black Friday They've got to be kidding! ----- 001 Kaba Kick There's no getting around it, Kaba Kick is Russian Roulette for kids. The player points the gun at his or her own head and fires. Instead of bullets, a pair of feet kick out from the barrel and player earns points for every time the gun doesn't fire. ----- 002 E.T. Finger Light Nothing wrong with this design except everything. ----- 003 The Breast Milk Baby There has been plenty of controversy surrounding "The Breast Milk Baby" which is indeed a real product that allows girls to simulate the act of breastfeeding. Some feel that the doll reinforces healthy, nurturing behavior while others feel it's way too mature for young girls. It's also $90. ----- 004 Wonder Woman Scissors Nope. ----- 005 Growing up Skipper To teach girls about puberty, "Growing Up Skipper" was released in 1975. The gimmick here was that if Skipper's arm was rotated, she would grow an inch taller and small breasts would poke through her rubber torso. ----- 006 Punisher Shape Shifters Power Pistol Oh come on, seriously? ----- 007 Baby's First Baby Ok, this isn't a real toy available for sale, it's a piece of art created by Darren Cullen. But it's still pretty creepy. ----- 008 Oreo Barbie What was meant to be an innocent cross-pollination between Nabisco and Barbie went sour quickly when "Oreo Barbie" received quite a bit of racially charged backlash. ----- 009 Inflatable Wolverine Hammer Toy More like triple X-Men.
JD and Kristina chime in on the pros and cons of this nationally recognized kick-off to the shopping season. What are your thoughts?
Warmer temperatures and less emphasis on Black Friday helped retailers gain steam in December. 'Traffic has been really strong,' said Morningstar analyst Paul Swinand in an interview with TheStreet's Scott Gamm. 'The weather has been just cold enough to get people inspired, but not cold enough to keep people away from the stores.' He says some of the snowy weather in November pushed people to shop in December. Swinand also talks about some of his favorite stocks in the retail sector, including Nike (NKE), which has strong financial metrics and Adidas (ADS), which he thinks will see improvements in U.S. market share during 2015.

He is the first designer from this part of the globe to win the International Woolmark Prize that carries a reward of AUD 100,000 and an opportunity to showcase his creations at prestigious fashion houses in the West. T. Krithika Reddy talks to Rahul Mishra about his efforts to make wool trans-seasonal, his fascination for the lotus motif and new-found international recognition
Celebrities and famous journalists from Europe tweeted excitedly about his win. In fact, Vanessa Friedman, Fashion Editor, Financial Times, asked if Rahul Mishra will be the next Karl Lagerfeld. Winning accolades is a way of life for this young designer whom French style guru Didier Grumbach described as a "talent to watch out for" in his formative years. When Mishra's name was announced as the winner of the International Woolmark Prize at the Milan Fashion Week recently, the fashion fraternity in India wasn't surprised. "We knew he would make it," they said in a cheery chorus, fully aware of the designer's efforts to engineer an all-weather friendly fabric from Merino wool using Indian weaving techniques. The utilitarian approach to wool teamed with his pared down sense of drama and innovative techniques proved to be the strong points of a collection that catapulted this Mumba-based designer to international stardom.
Despite dozens of interviews waiting to happen, Mishra opens up to MetroPlus in an exclusive interaction from Milan. Excerpts:
You worked for several months on this collection. What was going on in your mind before the award was announced?
I wanted to give the competition my best, so my commitment was 100 per cent. I was very nervous and stressed out before the announcement was made. I just kept telling myself, "Do not expect anything. You've done your best, now, it is God's wish." It's a tough competition. I was continuously praying.
You've competed with big labels from across the world. What was the immediate response from the audience when the award was announced?
It was a memorable show. During fitting and rehearsals, many people said the collection looked great and that it was their favourite. Even the seamstresses kept saying "bellissimo" (very beautiful). The show went off really well. The audience loved every bit of it. I actually saw people getting emotional, crying and praying for me. To me, when something is as beautiful as poetry, it touches people's heart.
Wool is a new medium to you. What were the specific challenges of working with it?
The biggest challenge was to fight the notion of wool being just a winter fibre. I had to change mindsets and convince weavers about my new vision. I think everyone in my team responded really well to this idea and we succeeded.
What are the handcrafts you used on wool?
I worked with Chanderi weavers to evolve a new weaving methodology to make Merino wool trans-seasonal. This led to participation from the handicraft and handloom sectors of rural India.
The ultra-light translucent Merino wool textile is the result of a new design intervention with the old weaving technique of Chanderi where 1/80nm Merino wool weft is used on a silk warp. The hexagon pattern is created by using the extra weft weaving technique, which is like doing hand embroidery with 2/80nm Merino wool yarn on the loom. The result is a one-of-its-kind finest Merino wool blend (wool 84 per cent and silk 16 per cent). Everything from the embroidery to the colour blending finish was achieved using hand skills that India is famous for.
Lotus has been your favourite motif. How do you think it suited a woollen line as well?
I love the lotus motif, especially the graphic open lotus as it sits perfectly in symmetry. There's great geometry — progressive geometry — about it. It is more like mathematical artistry. Saraswati, the Goddess of Knowledge and Wisdom, sits on an open lotus. I think it is really critical to get new ideas. To me, the lotus is a source of ideas.
Merino wool is a natural, biodegradable and renewable fibre that's great for clothing. The open lotus represents purity of wool.
What are the guiding principles in your work?
As a brand, I believe in not just designing a product focussed on CONSUMPTION. I'm also trying to design a system to create more PARTICIPATION. This participation happens with involving craft people who have been working for generations and are masters in their skill. We train them to understand modern design and production methods. I also believe that any handwork or craft is at its best if it stays at the place of its origin. So I keep them in their villages and take work to them rather than calling them to work in the cities. I always think of the three Es when I start to create a collection: environment, employment and empowerment.
How do you think designers can take the concept of sustainable luxury forward?
The focus behind my collection was the idea of sustainable luxury through participation. The idea revolves around the quote by Mahatma Gandhi — "Recall the face of the poorest and weakest man you have seen, and ask yourself if this step you contemplate is going to be of any use to him." I think the best fashion can be created when one looks into the past to create something for the future. The idea of fashion is strongest when a unique design language evolves based on culture and tradition. Luxury is about reinventing traditional handloom textiles and crafts for niche markets.
Besides the prize money, what's the commercial outcome you foresee post-award?
The real hard work starts now as we have to prepare for year-long launches at the most important stores of the world. I will travel to all the places as the launch of the collection will be a strong media and PR-driven exercise. I will have to work extra hard to handle all the orders. I have to plan my year carefully. I also want to show at an international pageant. But before that, I will showcase this collection at the Wills Lifestyle India Fashion Week, and expand this line into a bigger one and make it more suitable for Autumn-Winter.
It must be a new experience to see yourself on world-famous fashion glossies, blogs and websites....
The experience has been quite surreal. Hilary Alexander (Fashion Director, The Daily Telegraph) tweeted about my win, Financial Times Fashion Editor Vanessa Friedman said, "The Woolmark Prize winner is Rahul Mishra from India. Will he be the next Karl Lagerfeld? All this actually makes me more nervous. All the media and fashion magazines wrote about the win. There are dozens of interviews pending. It's exciting and I need to make the most of this attention and work even harder.
Has anyone from the Indian government congratulated you on this award?
No, not so far…I don't know if they are even aware.

President Obama gave a ringing defense of progressive government and the good it can do for the nation and the people. But a little-noticed addition to the fiscal-cliff bill was a reminder of how politics can work to the advantage of corporate special interests, say Bill Moyers and Michael Winship.

'Fixing the Debt' on Average Folks
Goldman Sachs' Lloyd Blankfein and other tycoons behind "Fix the Debt" want average folks to expect less from Social Security and other safety-net programs but are doing all they can to protect their special interest tax breaks and dodge the slightly higher tax rates for the rich, note Bill Moyers and Michael Winship.
The Madness of the NRA
The American Right has fabricated a false narrative about the Second Amendment to justify the ongoing slaughter of children and thousands of other civilians across the United States. But the NRA's pro-gun arguments sometimes even go beyond satire, as Bill Moyers and Michael Winship explain.
Congressmen Eye Revolving Door
Outgoing members of Congress – even as they consider legislation in the lame-duck session – are preparing their exits through the revolving door to lucrative lobbying jobs, often with industries they assisted while doing the "people's business," as Bill Moyers and Michael Winship explain.
The Revolving Door on Healthcare
Washington is a place where behavior – friendly to the rich and powerful – is rewarded lavishly and other behavior – hostile to those interests – can make you a pariah. That reality is reinforced when public officials make trips through the revolving door, as Bill Moyers and Michael Winship note.
Murdoch Seeks Help from Team Obama
Since the 1980s, Rupert Murdoch has built his U.S. media empire in close collaboration with the Republican Party, trading the his public influence for favorable regulatory treatment from GOP politicians. But now he is hoping for some help from President Obama's regulators, say Bill Moyers and Michael Winship.
The Enigmatic Prince Sihanouk
Cambodia's Prince Sihanouk was one of the Vietnam War era's most fascinating characters, a mass of personal contradictions who mastered political opportunism. He finally passed from the global scene this month, as Michael Winship recalls Sihanouk's remarkable life.
Lining Up Romney's Votes
America's concentration of wealth at the top has been accompanied by a bolder assertion of political power by the plutocrats, not just in the proliferation of unrestrained Super PACs but also in demanding support for Mitt Romney by employees, note Bill Moyers and Michael Winship.
Buying 'Justice'
Powerful corporations and right-wing interest groups are taking aim at state judges around the country who have ruled the "wrong" way and who can be tossed out via elections. This new flood of campaign cash is creating a system of justice for the highest bidder, write Bill Moyers and Michael Winship.
GOP Defends Marianas' Sweatshops
Scandal-stained Republican activist Ralph Reed is back in the GOP's good graces with a new "grassroots" operation organizing right-wing Christians. Also back on the Republican agenda is protection for an old Reed cause, maintaining sweatshops in the Marianas, note Bill Moyers and Michael Winship.

Creator to discuss online math encyclopedia March 24
What began as a simple list of numbers on cards has grown into a massive, searchable online math database.
Creator Neil Sloane will talk about that contribution to math and science when he lectures March 24 at the University of Louisville.
Sloane, a scientist at AT&T Shannon Labs, will give the free, public talk, "The Online Encyclopedia of Integer Sequences," at 6 p.m. in Room 101, Strickler Hall. Sloane's talk is the annual Bullitt lecture sponsored by the UofL mathematics department.
The Bullitt family endowed the general-interest lectureship to honor former U.S. Solicitor General William Marshall Bullitt's interest in mathematics.
Sloane has been running the database of number sequences for 47 years, although the site of 200,000-plus entries recently has been turned into a wiki with many associate editors. Mathematicians and other scientists search it daily by numbers or by sequence names.
Sloane has written books on topics ranging from error-correcting codes to rock-climbing and has been with AT&T, formerly Bell Labs, since 1969. His numerous awards include the Mathematical Association of American's Chauvenet Prize in 1979, the Institute of Electrical and Electronics Engineers' Hamming Medal in 2005 and the IEEE Information Theory Society's Shannon Award in 1998. He received his electrical engineering doctorate from Cornell University in 1967.

Creighton Medical Laboratories First to Offer New Cancer Test
The method, called SNP array karyotyping, has been successfully used in
research laboratories to study cancer for several years. However, Creighton Medical Laboratories, using AffymetrixTM SNP arrays, is the first laboratory to validate the test in a clinical setting and make it available for routine clinical use.
The method can help doctors make more accurate cancer diagnoses and tailor patient management based on the DNA profiles of each person's cancer.
Array-based karyotyping is a 21st century spin on older genetic testing methods that have helped guide patient care for decades. DNA is bundled inside cells as chromosomes; a karyotype is a representation of all of the chromosomes in a cell. Normal human cells have two copies of each
chromosome. Cancer cells will often duplicate or lose pieces of chromosomes, and these chromosomal changes can help physicians categorize a tumor, determine its aggressiveness, and/or determine which tumors will respond to specific drugs.
With the new method being used at Creighton Medical Laboratories, DNA from
tumor cells is applied to the arrays and scanned into a computer. The chromosomes are reconstructed by the computer to provide a genome-wide view of the cancer cells at unprecedented resolution; physicians then 'surf' the cancer genome using web-based genome browsers.
"SNP array karyotyping is a powerful new tool in our molecular tool box," said
The SNP (single nucleotide polymorphism) array used by
"As an example, with SNP-array virtual karyotypes, we have detected copy neutral LOH at important regions of the cancer genome, like the p53 gene in chronic lymphocytic leukemia. If the tumor has no functional copies of this important gene, it tends to behave aggressively, and the treating physician may want to treat it more aggressively," Hagenkord said. "This genetic lesion would not have been detectable with the current testing methods, which really underscores the importance of having this new testing method available clinically."
"We are very fortunate to have Dr. Hagenkord at the helm in clinical genomics, since she is currently the only pathologist worldwide with fellowship training in both molecular genetic pathology and pathology/oncology informatics. She has been performing SNP array karyotyping of tumors since the technology emerged and she is truly an expert in the field."

A signal transmitting and receiving system to track the position and orientation of limb segments in order to provide feedback information for the control of the limb movement. The user will generally be seated in a wheelchair that provides a structure upon which orthogonal and/or non-orthogonally oriented coils can be mounted and energized selectively so as to create variously oriented magnetic fields. Multiple wireless sensors injected into the limb detect the local field strength and send information telemetrically to a central controller. The controller extracts information about the position and orientation of each limb segment by combining signals from various sensors according to calibration information and optimal filtering methods for extracting information from multiple nonlinear sensors in mechanically constrained systems.
1. A position and orientation detecting system to measure movement of a limb described with six independent position and orientation variables, comprising:
a) one magnetic field source, comprising an AC source and a transmitter coil energized by an asymmetrical current waveform, configured to be located external to the limb and to generate at least one magnetic field;
b) six physically separated, non-orthogonally oriented capsules configured to be implanted within the limb, each capsule having a sensor configured to sense the magnetic field and to telemetrically transmit at least one signal corresponding to the sensed magnetic field, wherein the transmitted signal comprises phase data; and
c) a controller configured to receive the transmitted signals, to compute the position and orientation of the limb based on the transmitted signals, and to generate information useful in controlling movement of the limb based on the transmitted signals;
wherein the product of the number of the magnetic field source and the capsule is six.

No. 11/457,101, filed Jul. 12, 2006, now abandoned entitled "Method and Apparatus for Detecting Object Orientation and Position," which is related to and claims the benefit of the filing date of U.S. Provisional Patent Application Ser. No. 60/698,313, filed Jul. 12, 2005, entitled "Method and Apparatus for Detecting Object Orientation and Position," the contents of both of which are incorporated herein by reference.

Loeb, the contents of which are also incorporated herein by reference.
1. Field of the Invention
The present invention relates generally to implanted devices and methods for detecting object orientation and position.
2. General Background and State of the Art
Wireless micro-stimulators such as the BION� implants (U.S. Pat. Nos. 5,193,539, 5,193,540, 5,312,439, and 5,324,316; herein incorporated by reference) can be injected into paralyzed muscles or the stumps of amputated limbs to restore voluntary control of limb movement. In order to control neuromuscular stimulation, it is desirable to provide information about the posture and movement of the limb. Two sources of such information can be distinguished. The first derives from the fact that most patients will have residual voluntary control over some portions of the limb. Such voluntary movements can be sensed by the present invention in order to provide command information about the patient's intended limb movements. The second derives from the use of feedback information to improve motor performance. The movements produced by stimulation of the muscles can be sensed by the present invention, thereby providing feedback signals that modify the electrical stimulation pattern in order to achieve the desired limb movement. In both cases, it is desirable to employ sensors that are no more intrusive than the injectable stimulators themselves. Furthermore it is desirable to minimize the number of separate devices that must be injected into the patient while maximizing the information that is available for control of the prosthetic system.
There are many technologies for tracking and measuring limb movement in the laboratory but these generally require physically affixing sensors or markers to the surface of the limb. Most commonly, the position and/or orientation of these sensors or markers are determined by capturing optical information by video cameras or photodiode arrays whose position and line of sight must be carefully determined and maintained. Search coil systems use large coils to create homogeneous, orthogonally oriented magnetic fields around the subject, which are detected by a detection coil such as attached to a contact lens to track eye movement. Polhemus Technology (U.S. Pat. Nos. 6,624,626 and 6,400,139) and Ascension Technology (U.S. Pat. Nos. 6,528,991, 5,953,683, and 4,945,305) use externally mounted sensors consisting of three orthogonal detection coils to detect the relative strength of a magnetic field created by an external field generator. In these magnetic sensing systems, the magnetic sources can be AC (U.S. Pat. No. 6,690,963), DC (U.S. Pat. No. 4,945,305) or sourceless (U.S. Pat. No. 5,953,683 earth magnetic field). There are also mechanical transducers such as electrogoniometers produced by Infotronic Company that can be affixed across adjacent limb segments to detect angular rotation of the joint in one or two axes.
The prior art includes a fully implanted sensor of a single joint angle based on the effect of a permanent magnet on a nearby Hall-effect sensor. The magnet is implanted in the bone on one side of the joint and the Hall-effect sensor is implanted on the other side of the joint so that changes in joint angle produce a systematic change in the relative orientation of the sensor to the magnet. The sensor is connected by electrical leads to an implanted signal processor that, in turn, transmits data by wireless telemetry to an external controller.
The prior art includes a sensing system to track the tip of an intravascular catheter as it is maneuvered within a patient (U.S. Pat. No. 6,690,963). This system uses a large external array of magnetic coils to create a magnetic field that is sensed by orthogonal sensing coils contained within the tip of the catheter. In the preferred embodiments of the invention the coils have mutually orthogonal axes. The coils are closely spaced along the axis of the catheter. The magnetic field generating coils are arranged across the surface of the table on which the subject lies. The sensing coils are connected by electrical leads passing along the catheter to external signal processing instrumentation. This system basically uses the same mechanism as the concentrated orthogonal 3-axis magnetic sensor mentioned above. Sensing coils with distributed positions and orientations will present more than one local minimum points in the problem. Algorithms without global optimization technique tend to set design limitations on sensing coil arrangement such that the coils are close enough to the concentrated and orthogonal configuration.
Various algorithms have been described to transform the amplitude and phase information detected by sensors into conventional coordinate frames. Both rotation matrix and quaternion have been used to provide complete descriptions of 3-D orientations and rotation transforms. Mathematical methods exist to convert between them or combine them into hybrid representations. The data processing methods include both iterative and non-iterative techniques. U.S. Pat. No. 6,690,963 teaches numerical algorithm to solve the nonlinear equation group. But it does not investigate the local minimum points associated with the numerical process. In fact, if the receiving coils and transmitting coils are not arranged properly, there will be local minimum areas that the conventional numerical methods mentioned in this patent cannot solve. In the prior arts, the filters applied to the sensing system include mean-square filters and Kalman filters. The selection of appropriate methods for computing and describing position and orientation is an important part of the design of a sensing system that determines its practicality and performance in a given application.
In one aspect of the position and orientation detecting devices, a method to detect human limb posture comprises injectable distributed sensors of externally generated RF electromagnetic fields. These sensors and transmitters can be arranged at different locations with respect to the limb and they are allowed to have non-orthogonal and/or nonconcentric orientations with respect to each other, instead of being lumped in a single package as a 3-axis assembly. Keeping these sensors distributed instead of in the same package and making them nonorthogonal offers more freedom especially in medical applications such as control of Functional Electrical Stimulation (FES). In FES control, a preferable design is to have sensors and nerve stimulators packaged in the same implantable micro-capsule. Wireless sensors that are implanted into the human body need to be physically small and to function with low power consumption. The distributed scheme makes possible a sensing system with single-axis search coil sensors each of which can be packaged into an elongated micro-capsule that can be injected into the limb rather than requiring open surgical implantation. In an exemplary embodiment, the sensing coil is the same as is already required in the implanted microcapsule in order to receive power from and exchange data with an external controller.
In another aspect of the position and orientation detecting devices, a remote human limb position and orientation determining system comprises a plurality of radiating antenna coils to generate RF magnetic fields and a group of single axis micro-miniature sensing capsules with size and form factor suitable for injection into human limbs. Data acquisition, signal transmitting and receiving circuits are also in the capsules. The data can be sent by electromagnetic telemetry to an external coil. The external coil relays the data to a micro-computer, which acts as a signal processing unit.
In yet another aspect of the position and orientation detecting devices, synchronizing techniques enable the system to get not only the amplitude, but also the phase of the RF magnetic signal. The combining of phase and amplitude information makes the best use of the sensor output and is suitable for medical applications, which requires as few implants as possible. Various schemes are possible for gating and modulating the electromagnetic fields generated by each of the external coils sequentially or simultaneously and relating the state of the transmitters to the amplitude and/or phase of the signals detected at known times by each sensor.
In still a further aspect of the position and orientation detecting devices, the computing algorithms comprise a composite optimization process including genetic algorithm and gradient based local optimization. The algorithm produces position and orientation information based on the sensor signals. The information is then fed through an Extended Kalman Filter to suppress noise. The solution is accurate, fast and continuous.
Aspects of the present invention are illustrated by way of example, and not by way of limitation, in the accompanying drawings, wherein:
The detailed description set forth below is intended as a description of exemplary embodiments of the present invention and is not intended to represent the only embodiments in which the present invention can be practiced. The term "exemplary" used throughout this description means "serving as an example, instance, or illustration," and should not necessarily be construed as preferred or advantageous over other embodiments. The detailed description includes specific details for the purpose of providing a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the present invention.
The inductive coils are likely to be non-concentric and similar or smaller in size to the distances between each other and between the coils and the sensors. This is substantially different from electromagnetic position sensing technologies employed in the prior art, in which very large coils are used to create uniform fields in the vicinity of sensors or in which very small coils are used to create uniform gradients in field strength in the vicinity of the sensors. As illustrated in
One Exemplary Embodiment of the Present Magnetic Sensor
Functional electrical stimulation (FES) of paralyzed muscles has traditionally focused on getting muscles to produce the requisite torques required for limb movement. Micro-implants called BION� implantable microstimulators (BION is a registered trademark of Boston Scientific Neuromodulation Corporation, Reg. No. 2455608) have been developed to interface with the multiple muscles required for most tasks. They are modularly designed wireless capsules that can be injected into the human body without requiring surgery. Separately addressable BION's (selectively used as a noun hereinafter merely for convenience purposes) can be implanted at various sites in the body near motor nerves, where they receive power and digital command data from an external RF coil and deliver stimulating current pulses to recruit the motor neurons and activate associated muscles. Given appropriate control strategies, this technology could be used to create functional movement in limbs paralyzed by upper motor neuron disorders such as spinal cord injury and stroke.
As the functions to be implemented by BIONs become more demanding, the prosthetic system may include a growing armamentarium of sensors to detect voluntary command signals and to provide sensory feedback to regulate neuromuscular stimulation. Furthermore, these sensors and actuators may be readily combinable into custom configurations to deal with the inherent heterogeneity of patients with diverse physiognomies and lifestyles suffering from wide ranges of traumatic and neurological deficits. Attaching and wiring miscellaneous sensors on the body is not an attractive design for most scenarios of FES application, however. Activities of daily living such as bathing and sleeping require frequently detaching and re-attaching these sensors, which may be difficult and which is likely to result in problems with system calibration. External sensors are likely to be uncomfortable and vulnerable to damage. In an exemplary embodiment, the sensors may be integrated with the implants for one-time injection and long-term usage. The micro-coil within each BION implant may act as a magnetic sensor.
Also, as illustrated in
RF Magnetic Signal from a Dipole Ring Antenna
The BION implant consists of an electronic subassembly with an integrated circuit chip surrounded by a hermetically sealed glass capsule with external electrodes. The BION also includes a cylindrical coil around a hollow ferrite core that is the antenna of the implant. The coil is connected to the input pads of an ASIC through a ceramic hybrid substrate. In normal operation, it receives power and command data from a frequency-modulated RF magnetic field generated from an external coil worn in the vicinity of the implants. The strength of the received signal depends on the relative distance and orientation between the external and internal coil. The normal external coil can be turned off briefly while one or more other external coils in known positions are used to create a magnetic field for the implant coil to detect. The measured field strength will be sent by reverse telemetry to an external controller that will compute the position and orientation of the implant with respect to one or more such external reference coils. The antenna coil of the Bion implant is used as a magnetic sensor.
In the following description the coordinates for a coil is established according to these rules:
As illustrated in
Having a sensing coil at this point, the induced voltage sensed by the receiving coil can be calculated based on equation (1):
Transmitter and Sensor Configuration
An alternating magnetic field generated by one or more external transmitting coils induces voltage in the antenna of the BION implant, which is a function of relative orientation and position between the antenna coil and the field transmitters. Each BION receiver coil detects the derivative of this reference field projected to the coil axis. Thus each transmitting coil and receiving coil pair provides constraint on one degree of freedom (DOF). To constrain six DOFs on position and orientation, the sensing system needs at least six such transmitting and receiving pairs; for example, 2 sensing coils and 3 transmitting coils that can provide 6 independent combinations. Because induced voltage in a sensing coil is independent of its axial rotation, only 5 DOFs can be resolved when the sensing is based on one sensing coil. A 2-axis MEMS accelerometer in the same capsule can detect the 6th DOF from the static effects of gravity (as long as the long axis of the implant is not oriented exactly vertically) and also provides some redundancy for magnetic sensing.
The 3-D position and orientation of a rigid body altogether contain 6 independent variables if the position and orientation of the transmitting coils are known. There are 3 variables, x, y, and z, which are coordinates of the receiving coil in the reference frame 1 (x1-y1-z1) as shown in
So the position and orientation of a rigid body can be described with six independent variables, x, y, z, α, β, and γ. To solve these six variables we need at least six equations. Equation (2) says that one transmitting coil and one receiving coil can make one non-linear equation. Therefore to calculate 6 variables we need the product of the number of the transmitter and the receiver to be 6. The least configuration can be
In most FES application, multiple BIONs will be in each limb segment. If they are non-colinear magnetic sensing alone can detect all 6 DOFs. A successful FES system usually takes more than 2 sensor-stimulator implants to function because human limb joints are controlled by complimentary muscle groups. Because it is desirable to employ as few implants as possible, it is more desirable to add in more transmitters if there are no other constraints. In the following we make the assumption that there are 3 transmitters and 2 receiving coils. But the derived method can be easily extended to other different configurations. Increasing the number of transmitters or receiving coils can provide redundancy that can be used to minimize sensor noise with sensor fusion filters.
It may also be difficult to keep the relative orientation and position of the implants fixed. This is because of the implants being normally injected into different muscles that slide with respect to the skeleton and each other. Exemplary embodiments of the position and orientation detecting devices also provide a method to calibrate empirically and to correct mathematically for such posture-dependent motion of individual BION implants.
Sensing Position and Orientation with Distributed Receiving Coils and Lumped Transmitters
The minimum setup for the sensing system should produce six equations to make the problem solvable. But the clinical scenario is different from patient to patient. Many possible configurations can be chosen to fit the clinical requirements.
The RF transmitters are outside of the human body, where we can have more space and more freedom in arranging the hardware. The first configuration of the sensing system is to have the transmitting antennas be lumped at the same location and they are arranged to be orthogonal in orientation as shown in
The magnetic fields produced and detected in this sensing system were not significantly affected by nearby metal objects as long as they did not come between the reference field transmitters and implanted sensors. Distortion effects arise from the induction of eddy currents in the metal objects, which then generate their own magnetic fields, distorting the field to be sensed. The received signal declines rapidly with distance from the transmitting coils (generally with the distance cubed), so it is advantageous to position the transmitting coils so that they are generally close to but at varying distances from the various sensors implanted in the limb.
Many candidates for FES to reanimate the arm and hand are confined to wheelchairs, e.g. quadriplegia following spinal cord injury. The sensing scheme has a transmitting box that can be installed on the armrest of a wheelchair (
By locating the transmitting coils in the armrest, it is unlikely that large metal objects will come between transmitting and sensing coils. One exception, however, is the transmitting coil that powers the implant, which is designed to be worn on the arm itself. We have demonstrated that the electromagnetic effects of this coil are negligible if this coil is disconnected from its driver circuitry by an electronic switch for the brief intervals during which position measurements are made.
Configuration 1: Lumped Transmitters and Distributed Sensors
In this configuration, there are two possible outcomes depending on the clinical condition of a patient. The implanted BIONs could be in close proximity to each other or they could be far from each other.
In case the BIONs are in close proximity, if we turn on the orthogonal transmitting coils in sequence, we can measure six voltages from two BION sensing coils according to equation (2).
Then we have nine unknown variables:
If the actual measured voltages from the BION coils are
Then we can define an object function:
In case that the two BIONs are injected and placed far from each other, the assumption of equation (4) would not hold. We then have to modify the constraints to include position information:
The optimization and filtering process will generate the position [x, y, z]′ and orientation [nxnynz]′, which can be converted into Euler angle or polar angles. This information can be further used to compute human limb postures.
Configuration 2: Distributed Transmitters and Sensors
In FES biomedical engineering applications, the BION implants work as muscle stimulators at the same time. In this case there is a RF transmitter for each group of these implants. It is therefore desirable to have these transmitters be re-used for RF magnetic sensors. This can be arranged at different place on a wheelchair according to medical requirements. This is the situation when both transmitters and receivers of the sensing system are distributed and non-orthogonal.
In the second configuration of the sensing system, the transmitting antennas are placed at different locations and in different orientation, if necessary.
As illustrated in
The relationship of the distributed transmitting coil positions can be expressed as 4-dimension rotation matrices. For example:
Similarly the rotation relationship between different reference frames can also be expressed with 3-dimension rotation matrices. For example:
With these transformations the problem can be described as a similar optimization problem with the last configuration. Even though the second configuration means more variables and constraints, basically it is still the same optimization problem with the configuration one. Similarly the global optimization technique can be used to compute the posture at a single time interval. Then the Extended Kalman Filter can be used to reduce noise.
Signal Processing Techniques
U.S. Pat. No. 6,690,963 described the signal processing problem for multi-transmitter and sensor as solving a non-linear equation group with numerical methods such as Newton-Raphson method and Broyden's method. These traditional gradient based methods work only when the transmitters and receivers are properly located and orientated. Basically the nonlinear optimization problem presents local minimum areas. To find the solution for a wider range of system configurations, we have to look into global optimization techniques.
The problem of extracting position and orientation information from the sensors is a global non-linear optimization problem. The object function in equation (7) has many local minimums. Global optimization techniques such as genetic algorithm and simulated annealing can avoid local minimum points and get the solution equal or close to the true solution. Genetic algorithm (U.S. Pat. No. 5,255,345) and simulated annealing are typical global optimization methods that can be employed as a part of the signal processing stage. For the specific problem we are working on, genetic algorithm presents pretty good performance in bringing the solutions close to the true minimum point. To deal with the inequality and equality constraints as shown in equation (5), we can either use a constrained genetic algorithm or we can convert the problem into a non-constrained problem by combining the constraints with the objective function. The implementation of a genetic algorithm should be familiar to people with expertise in related area.
However, genetic algorithm does not work well in asymptotic convergence, while traditional gradient-based optimization techniques are good at this job. To take advantage of both of these techniques, we can combine these into two steps. In the first step we use genetic algorithm to avoid local minimums and get close to the true minimum point. In the second step we can use traditional optimization techniques known as prior art to achieve asymptotic convergence. Similar with the genetic algorithm, both constrained and non-constrained optimization techniques can be employed to solve the problem. In our simulation, it takes less than 80 generations of genetic algorithm and 100 iterations of the traditional optimization to achieve error level better than 1%.
The sensor signal can never be noise free since environmental electromagnetic interference and non-ideal transmitter and receiver shapes. Extended Kalman filter can be employed to this nonlinear system to suppress noise. Kalman filter can also make use of the movement history information and help to avoid the algorithm being trapped in singularities. The overall signal processing diagram is shown in
Judge Signal Phase with Synchronized Transmitters
The orientations of the receiving coils with respect to the transmitting coils are not only reflected by the amplitude of the sensed signal, but also described by the phase of the sensed signal. Specifically, if the sensed signal is in the same phase with the transmitted signal, then the sensing coil should orientate within +/−90 degree of the transmitting coil flux tangent. Otherwise the sensing coil should orientate in the other direction, i.e. 90-270 degrees with respect to the transmitting coil flux tangent. The conclusion in the last paragraph is based on the assumption that the sign of the voltage V in equation (2) can be detected. Therefore the phase of the sensed signal contains important information about the coil orientation. To judge the coil, we propose the synchronizing method as shown in
For a typical wireless FES treatment, the patient needs an external transmitting coil to provide power and command signal wirelessly to the implanted muscle stimulator. If we synchronize the signal from this coil and the transmitting antenna for the RF magnetic sensor, we will be able to tell the phase of the sensed signal.
As illustrated in
This problem can be solved with a pulsed current generator such as can be produced by rapidly discharging a capacitor in a relaxation oscillator. The induced voltage on the BION sensing coil is negatively proportional to the time derivative of the flux and therefore the derivative of the current driving the external coil. If the driving current is an asymmetrical "sawtooth", then the faster first (positive) phase will generate a larger magnitude voltage in the sensing coil than the slower second (negative). The sign of the larger peak tells which direction the sensing coil is oriented with respect to the transmitting coil (see +/−voltage peaks in
Wireless Design
The BION implants are wireless capsules. The power and control signal are delivered wirelessly from an external coil. The detailed technique has been shown in U.S. Pat. Nos. 5,193,540; 5,324,316; 5,312,439 and 6,175,764. To send the signal out without significant power consumption, passive back-telemetry technique can be used. The implementation details are familiar to people who are experts in this area. A preferable implementation for the implant is to switch the received current into wave sequences as shown in
Cancel Muscle Deformation
The BION implants are designed to be injected into human muscles. The musculoskeletal system of the arm is actually not a rigid body, as assumed by the above algorithm. BIONs implanted in the muscles will move with respect to each other as the arm rotates.
If we install the BIONs properly into a pair of complementary muscles, we can keep their relative rotation and movement as small as possible. However the magnetic sensor is very sensitive to orientation change for certain angle range. A slight relative rotation might cause big error in measurement. If we can address the muscle deformation in our algorithm, we should be able to limit this error.
The musculoskeletal model of the human arm and two implanted BIONs are shown in
The matrix F can be measured experimentally from a large group of redundant data. Assuming we sampled n points from different postures, from equation (10) we can write the following equation:
With the linear approximation, we can re-write the optimization problem as:
Find x1, y1, z1, x2, y2, z2, α, β, γ (or q0˜q4 with quoternions) to minimize

From the opening bell, both fighters met in the center of the ring and traded punches. Southpaw Brähmer tried working from the outside in round two. But both fighters were back at it, landing big shots in round three and even more heavy leather was exchanged in round four, Brähmer's best round of the fight. Garay came back in the fifth round as both fighters continued to exchange. The sixth definitely went to Garay, who was clearly busier, while Brähmer seemed to be wearing down. Just a brutal war in the trenches as the bout progressed. Garay was simply quicker and outworked Brähmer, although Brähmer was connecting with hard shots also. The challenger was clearly slowing down entering the championship rounds as Garay pulled away on the scorecards. The hard-punching Brähmer spent the last round desperately attempting to land a big shot to end it, but Garay never let him have that opportunity.

Slightly more than a re-skin of FIFA 10, but not quite enough to make this definitive. [May 2010, p.84]
This is a fantastic title that not only all Wii owners, but every fan of the sport will find something to enjoy. This might be a strictly arcade affair, but once you accept that and just focus on trying to score as many goals as possible, you will find it difficult to put down.
