    Health Tracker is a simple yet powerful program which helps you keep track of and graph any health related measurement. For example, if you are diabetic you could track your blood glucose levels. It is available for both the Macintosh and Windows.

    Why doesn't it convert units of volume/energy/velocity...? SensibleUnits.com currently converts all major (and some obscure) units of length, area and mass. Other dimensions will be added in the near future.

    This short handbook provides guidance for policymakers struggling with two key issues: (1) What is the impact on student achievement of introducing ICTs in educational settings in developing countries? (2) How should this impact be measured, and what are the related issues, especially as they relate to Education For All and other Millennium Development Goals?

    "Kids are curious, and just as when they were toddlers, bound to get into things you'd rather they didn't. Without certain measures in place, your kids can access everything on the Web. And though nothing can replace your guidance and vigilance, there are some tools out there to help you make sure your kids are see¬ing the better things the Internet has to offer. "

    SAFE-Net, a Cyber Safety Awareness program of the Pittsburgh Supercomputing Center, focuses on raising the awareness of students, parents, and educators about cyber threats, measures of protection, and cyber ethics. Through this website, it provides materials to teach teachers, parents and students about cyber security issues. All materials can be downloaded free of charge. However, you will need to create a SAFE-Net account in order to access them. When you are logged in and agree to the Terms of Use, you will be given access to the materials.

  • 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."
