  • Metal complexes for enhanced dispersion of nanomaterials, compositions and methods therefor
    Patent number: 7976731
    Abstract: Metal complexes (“compatibilizers”) having properties particularly useful for treating and compatibilizing nanomaterials (i.e. carbon nanotubes, nanofibers, nanographite) include metal cations and anionic surfactants. The treated nanomaterials can be isolated as solid treated nanomaterial and used in further applications where increased dispersion is desirable.
    Type: Grant

  • Interactive television security through transaction time stamping
    Patent number: 5764275
    Abstract: A system for providing security on an interactive television system. Two sets of interactive data, with time stamps, are separately sent to a remote location. At the remote location, the time stamps are checked against a remote clock, a time difference being noted for both sets of data. The two time differences are compared to determine if one set of data has been delayed as compared to the other. Non-delayed data can be used to update a game score for an interactive game. After the game is completed, the remote clock is compared to a central clock. the difference between the two clocks are compared to the time difference for non-delayed data to determine whether the entire aggregate of interactive data was delayed.
