  • Xe biosensors and their use
    Patent number: 8470587
    Abstract: This invention relates to enzyme-sensitive biosensors and methods and kits using the same. Specifically, the invention relates to methods, systems and kits for the detection of enzymes using the chemical shift observed in an isotope complexed to the biosensor resulting from a change in the biosensor as the result of the enzyme's activity.
    Type: Grant
    Filed: August 6, 2007
    Date of Patent: June 25, 2013
    Assignee: The Trustees of the University of Pennsylvania
    Inventors: Ivan Dmochowski, Qian Wei, Nicholas Kuzma, P. Aru Hill
  • EARPHONE, SWITCHING SYSTEM AND SWITCHING METHOD
    Publication number: 20120230508
    Abstract: A earphone which can communicate with an electronic device includes a sensing unit, a determining unit and a communication unit. The sensing unit detects a rotation of the earphone to generate a direction signal and to obtain a rotating angle. The determining unit determines whether the rotating angle is at least a predetermined angle and generates a rotating signal when the rotating angle is at least a predetermined angle. The communication unit controls the electronic device to execute different operations.
