  • Three dimensional optical memory storage
    Patent number: 6733946
    Abstract: A method for providing three dimensional optical memory storage for computers. The method comprises subjecting a nanocomposite to irradiation. The nanocomposite comprises a matrix of particles of a liquid core resin within an inner shell resin and an outer shell resin. The inner shell resin retains the liquid core resin while the outer shell resin forms a continuous phase of the matrix. The particles of core resin contain at least one photosensitive compound and are in an array in the matrix. The continuous phase is substantially free of photosensitive compound. The irradiation may be a single beam of irradiation selectively focused on individual particles in the array to effect photobleaching of individual particles or a two-photon irradiation of a wavelength to effect photobleaching.
    Type: Grant

  • Bicycle locking system
    Patent number: 5007260
    Abstract: A locking system for use with a wheeled vehicle such as a bicycle is described. The system is useful either to lockingly secure a wheel to the fork members of a bicycle or to lockingly secure the seat post to the center frame member. The locking member is cylindrical in shape and covers a specially configured nut that replaces the usual lever operated nut used with a spindled axle system.
