Noteflight - Sign In - 2 views

  •  
    We built Noteflight because we looked at where software is today, and saw that applications for writing music were stuck in the past. We wanted to accomplish a few important goals: Make it easy to create and share written music online. People who make music -- amateurs and professionals, students and teachers -- want to share that music with others, sooner or later. But most software for working with notated music treats the Internet as an afterthought: it's geared to saving your music on your own computer's hard disk, not to sharing your music with other people. It's painful to share musical scores online today, and as software inventors, we knew how much better it could be. People expect to be able to do their creative work wherever they go, and a crop of new browser-based applications make it incredibly easy to create and publish word-processing documents or spreadsheets online. We feel musical documents should be just as accessible. Empower developers to build a new world of musical and educational applications. Applications today should be not only powerful tools, but building blocks that can be combined in ways that their creators have never foreseen. A truly powerful musical application should be extensible without having to open it up and change the code. Adding new instruments and symbols, or embedding in a page and building new kinds of connections with other content -- all of these things should be possible. A great tool lets creative people not only use its built-in capabilities, but extend them and freely reorganize them in new ways. As Bertrand Meyer, a pioneer of software thinking, once put it: "Real systems have no top". Encourage a vibrant community of users by keeping the basics free. Music notation software vendors continue to charge high prices for boxed software, CD and DVD distribution media, and printed manuals. Then once you buy something, you're basically stuck with it until the next major upgrade cycle comes around, at which point you pa

Medical devices powered by the ear itself - MIT News Office - 1 views

  • Health Sciences and Technology (HST) demonstrate for the first time that this battery could power implantable electronic devices without impairing hearing.
  • The devices could monitor biological activity in the ears of people with hearing or balance impairments, or responses to therapies. Eventually, they might even deliver therapies themselves
  • “In the past, people have thought that the space where the high potential is located is inaccessible for implantable devices, because potentially it’s very dangerous if you encroach on it,” Stankovic says. “We have known for 60 years that this battery exists and that it’s really important for normal hearing, but nobody has attempted to use this battery to power useful electronics.”

  • The ear converts a mechanical force — the vibration of the eardrum — into an electrochemical signal that can be processed by the brain; the biological battery is the source of that signal’s current. Located in the part of the ear called the cochlea, the battery chamber is divided by a membrane, some of whose cells are specialized to pump ions. An imbalance of potassium and sodium ions on opposite sides of the membrane, together with the particular arrangement of the pumps, creates an electrical voltage.
  • Low-power chips, however, are precisely the area of expertise of Anantha Chandrakasan’s group at MTL
  • The frequency of the signal was thus itself an indication of the electrochemical properties of the inner ear.
  • in cochlear implants, diagnostics and implantable hearing aids. “The fact that you can generate the power for a low voltage from the cochlea itself raises the possibility of using that as a power source to drive a cochlear implant,” Megerian says. “Imagine if we were able to measure that voltage in various disease states. There would potentially be a diagnostic algorithm for aberrations in that electrical output.”
  • “I’m not ready to say that the present iteration of this technology is ready,” Megerian cautions. But he adds that, “If we could tap into the natural power source of the cochlea, it could potentially be a driver behind the amplification technology of the future.”
  •  
    "For the first time, researchers power an implantable electronic device using an electrical potential - a natural battery - deep in the inner ear."

    "All of D-Lab's classes assess the needs of people in less-privileged communities around the world, examining innovations in technology, education or communications that might address those needs. The classes then seek ways to spread word of these solutions - and in some cases, to spur the creation of organizations to help disseminate them. Specific projects have focused on improved wheelchairs and prosthetics; water and sanitation systems; and recycling waste to produce useful products, including charcoal fuel made from agricultural waste."

Langwitches » Digital StoryTelling- What Comes to Mind? - 1 views

  • As many of you know, who follow me on Langwitches, I am working on a Digital Storytelling Guide for Educators. I will be using Wordle to create a storytelling cloud with Words that come to mind when you think what Digital Storytelling means to or for you. Please contribute keyWords, that come to YOUR mind when you think of storytelling in a comment. Don’t hesitate to add duplicate keyWords what digital storytelling means to you. That way Wordle will highlight more important keyWords. I will add your reponses through the comments and through Twitter and Plurk to Wordle and add the collaborative cloud to this post and as part of the cover art of the hardcover book that will be available for free download on Lulu.com . This cloud will be a digital story in itself, told by all of us!
