Hank Hogan

Powered wheelchairs both help and hinder users. Over short distances, the conveyances help people get around. However, for longer distances, where one typically would use a car, wheelchairs get in the way. Storing them safely for a trip is difficult — often requiring an assistant — and entails extensive and costly vehicle modification. Now a group of engineers from Carnegie Mellon University in Pittsburgh, Lehigh University in Bethlehem and Freedom Sciences LLC of Philadelphia, all in Pennsylvania, has devised a system that combines robotics, lasers and wireless technologies to enable a...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
