    Very interesting article describing the near market ready potential of "supercapacitor" batteries.   This is truly game changer stuff, and very interesting to me since i've been following the research and development of "graphene technologies" for some time.  The graphene superconductor targets the future of both energy and computing.  But graphene is also at the cutting edge of "faster, better, cheaper" water desalinization!  Nor does it take a rocket scientist to see that a graphene nano latice will have an enormous impact on methods of separating water (H2O) atoms to create an electical current - a cost free flow of electons.   Very well written research! excerpt: "an article in the recent issue of Nature Communications on a novel way to mass-produce so-called superconductors on the super-cheap - using no more equipment than the average home CD/DVD burner. Hacked together by a group of research scientists at UCLA, the ingenious technique is a way of producing layers of microscopically nuanced lattices called graphene, an essential component of many superconductor designs. It holds the promise of rapidly dropping prices for what was until now a very expensive process. You see, we've known about the concept of supercapacitors for decades. In fact, their antecedent, the capacitor, is one of the fundamental building blocks of electronics. Long before the Energizer Bunny starting banging its away around our television screens, engineers had been using capacitors to store electrical charge - originally as filters to help tune signals clearly on wireless radios of all sorts. The devices did so by storing and releasing excess energy, but only teeny amounts of it... we're talking millions of them to hold what a simple AA battery can. Over the years, however, scientists worked on increasing their storage capacity. Way back in 1957, engineers at General Electric came up with the first supercapacitor... but back then there were no uses for it. So, the technology

  • "We've put it in a user-installable module. The user buys the card and just plugs it into any device that has a slot," Fiennes explained." All a developer needs to do is add a socket and a 3-pin Atmel ID chip to their product. That's 75 cents: 30 cents for the ID chip and 45 cents for the socket." This assumes the availability of 3.3 V. "But given that most things you want to control from the Internet are electrical, we think that's reasonable," he said. If not, developers can include a battery.
  • Fiennes demonstrated a power adaptor with an Imp socket. He installed a card and an appropriately labeled block appeared in a browser window. Fiennes plugged in a chain of decorative lights and we clicked on the box on our browser. After clicking, the box text went from "off" to "on." Over Skype, we could see the lights had come on.Fiennes emphasized that control need not be manual and could be linked to other Internet apps such as weather reports, or to Electric Imp sensor nodes that monitor conditions such as humidity.A second example is an Electric Imp enabled passive infrared sensor. Fiennes demonstrated how it could be programmed to report the time and date of detected motion to a client's Web pages on the Electric Imp server. In turn, those pages could be programmed to send an alarm to a mobile phone. The alarm could also be triggered if no motion was detected, allowing the sensor to serve as a monitor for the elderly in their homes, for example. If there is no activity before 9 a.m., a message is sent to a caregiver.
  • The final example is an Electric Imp washing machine. Machine operation can be made conditional on a number of variables, including the price of electricity. "Every washing machine has microcontroller and that microcontroller has a lot of data," said Fiennes. "That data could be sent back to a washing machine service organization that could call the client up before the washing machine breaks down."

  • The cards will be on sale to developers by the end of June for $25 each and Electric Imp will also supply development kits that include a socket, ID chip and power connection on a small board for about $10. While these are intended for consumer electronics developers Electric Imp is happy to sell them to students and non-professional developers. "Hobbyists can play with it and tell us what they think."

    Put Electronic Imp at the top of the "Technologies to watch" list.  Good stuff and great implementation - platform plan.   excerpt "We've put it in a user-installable module. The user buys the card and just plugs it into any device that has a slot," Fiennes explained." All a developer needs to do is add a socket and a 3-pin Atmel ID chip to their product.

"But given that most things you want to control from the Internet are electrical, we think that's reasonable," he said. If not, developers can include a battery. When the $25 card is installed in a slot and powered up, it will find the ID number and automatically transmit the information to Electric Imp's servers. Fiennes and his colleagues have written a virtual machine that runs under a proprietary embedded operating system on the node and looks for updates of itself on the Internet. SSL encryption is used for data security when transmitted over the link. ........

rare-earth-metals China trade-war nuclear-option

shared by Paul Merrell on 19 Aug 19 - No Cached
  • The escalating US-China trade conflict has raised concerns about the measures each side could use in their fight, including Beijing’s option to restrict exports of rare earth metals. The economic measure is dubbed as one of Beijing’s nuclear options in its battle with Washington due to the fact that China is the top producer of rare earth metals and holds the largest reserves.
  • The United States relies on China, the leading global supplier, for about 80 percent of its rare earths.
  • China controls around 85-95 percent of all the rare earths’ production and supply. Last year, the country produced about 78 percent of the global volume of rare earths.

  • The metals and alloys that contain them are used in many devices that people use every day such as computer memory, DVDs, rechargeable batteries, cell phones, catalytic converters, magnets, fluorescent lighting and so on.During the past 20 years, there has been an explosion in demand for many items that require rare earth metals. There were very few cell phones in use then but the number has risen to over seven billion in use today. Rare earths’ use in computers has grown almost as fast as the number of cell phones.Many rechargeable batteries are made with rare earth compounds. Demand for the batteries is being driven by demand for portable electronic devices such as cell phones, readers, portable computers, and cameras.Rare earths are also used as catalysts, phosphors, and polishing compounds for air pollution control, illuminated screens on electronic devices, and much more. All of those products are expected to experience rising demand.
  • He explained that China could cripple global industry, especially emerging technologies, if it were to ban exports of rare earth materials. There are very few options in sourcing those essential technology metals from anywhere else, the analyst said. “Of course, China does not necessarily want to do this, because, it plays a long game – and it does not want the West to develop alternatives.”

    Nvidia chief executive Jen-Hsun Huang is on a mission to get graphics chips into everything from handheld computers to smart phones. He expects, for instance, that low-cost Netbooks will become the norm and that gadgets will need to have battery life lasting for days. Holding up an Ion platform, which couples an Intel low-cost Atom processor with an Nvidia integrated graphics chip set, he said his company is looking to determine "what is the soul of the new PC." With Ion, Huang said he is prepared for the future of the computer industry. But first, he has to deal with Intel. Good interview. See interview with Charlie Rose! The Dance of the Sugarplum Documents is about the evolution of the Web document model from a text-typographical/calculation model to one that is visually rich with graphical media streams meshing into traditional text/calc. The thing is, this visual document model is being defined on the edge. The challenge to the traditional desktop document model is coming from the edge, primarily from the WebKit - Chrome - iPhone Community. Jen-Hsun argues on Charlie Rose that desktop computers featured processing power and applications designed to automate typewritter (wordprocessing) and calculator (spreadsheet) functions. The x86 CPU design reflects this orientation. He argues that we are now entering the age of visual computing. A GPU is capable of dramatic increases in processing power because the architecture is geared to the volumes of graphical information being processed. Let the CPU do the traditional stuff, and let the GPU race into the future with the visual processing. That a GPU architecture can scale in parallel is an enormous advantage. But Jen-Hsun does not see the need to try to replicate CPU tasks in a GPU. The best way forward in his opinion is to combine the two!!!

smartphone Apple Ericsson patent litigation

shared by Paul Merrell on 08 Mar 15 - No Cached
  • The licensing battle between Apple Inc. and Ericsson AB is escalating.Ericsson, a pioneer in mobile phones that transformed itself into the world's largest maker of wireless networks, said Friday it's filing seven new lawsuits in a U.S. court and is asking the U.S. International Trade Commission to block Apple products from the U.S. market.Together, the complaints accuse Apple of infringing as many as 41 patents for some of the fundamental ways mobile devices communicate and for related technology such as user interfaces, battery saving and the operating system.
  • Apple had been paying royalties to Stockholm-based Ericsson before a license expired in mid-January. When talks over renewal failed, the companies sued each other, seeking court rulings on whether Ericsson's royalty demands on fundamental technology were fair and reasonable.
  • The new complaints being filed by Ericsson at the International Trade Commission in Washington take the dispute to another level and are designed to put pressure on Apple. The trade commission, whose job is to protect U.S. markets from unfair trade practices, moves more swiftly than district courts and has the power to block products from crossing the border.Apple's iPhone, iPad and other devices are made in Asia.

shared by Paul Merrell on 10 Mar 16 - No Cached
  • The U.S. military is spending millions on an advanced implant that would allow a human brain to communicate directly with computers.If it succeeds, cyborgs will be a reality.The Pentagon's research arm, the Defense Advanced Research Projects Agency (DARPA), hopes the implant will allow humans to directly interface with computers, which could benefit people with aural and visual disabilities, such as veterans injured in combat.The goal of the proposed implant is to "open the channel between the human brain and modern electronics" according to DARPA's program manager, Phillip Alvelda.
  • DARPA sees the implant as providing a foundation for new therapies that could help people with deficits in sight or hearing by "feeding digital auditory or visual information into the brain."A spokesman for DARPA told CNN that the program is not intended for military applications.
  • But some experts see such an implant as having the potential for numerous applications, including military ones, in the field of wearable robotics -- which aims to augment and restore human performance.Conor Walsh, a professor of mechanical and biomedical engineering at Harvard University, told CNN that the implant would "change the game," adding that "in the future, wearable robotic devices will be controlled by implants."Walsh sees the potential for wearable robotic devices or exoskeletons in everything from helping a medical patient recover from a stroke to enhancing soldiers' capabilities in combat.The U.S. military is currently developing a battery-powered exoskeleton, the Tactical Assault Light Operator Suit, to provide superior protection from enemy fire and in-helmet technologies that boost the user's communications ability and vision.The suits' development is being overseen by U.S. Special Operations Command.In theory, the proposed neural implant would allow the military member operating the suit to more effectively control the armored exoskeleton while deployed in combat.

  • In its announcement, DARPA acknowledged that an implant is still a long ways away, with breakthroughs in neuroscience, synthetic biology, low-power electronics, photonics and medical-device manufacturing needed before the device could be used.DARPA plans to recruit a diverse set of experts in an attempt to accelerate the project's development, according to its statement announcing the project.

    Let's assume for the moment that DARPA's goal is realizable and brain implants for commuication with computers become common. How long will it take for FBI, NSA, et ilk to get legislation or a court order allowing them to conduct mass surveillance of people's brains? Not long, I suspect.
