  • Publication number: 20110250324
    Abstract: A handheld hydrosol delivery device includes a canister which is at least partially filled with a liquid formulation of one or more liquids and optional particles, and one or more propellants where at least one of the liquids, propellants, particles and combinations thereof is a flavor; a pressure valve which expels at least a portion of the liquid formulation and at least a portion of the propellant from the canister while dispersing the propellant into the liquid formulation forming a consumable flavored hydrosol comprising one or more gases dispersed within the liquid formulation, through a nozzle delivering the hydrosol to a user.

  • Patent number: 8023705
    Abstract: In a method for reconstructing an image from an echo planar imaging sequence, the echo planar imaging sequence is used to obtain multi-line k-space data from a subject and the multi-line k-space data are divided into odd line data and even line data. Fourier transform is performed on the odd line data and on the even line data separately to obtain corresponding amplitude images. The amplitude images obtained is this manner are added to produce the final image. The method effectively eliminates N/2 artifacts by over-sampling in the phase direction. By image reconstruction being carried out separately on the odd line data and even line data of k-space data and then integrating the images, the method effectively avoids the problem of the image signal loss caused by the mutual cancellation of the odd line data and even line data.

  • Patent number: 7934510
    Abstract: A wrapper for a smoking article includes nanoparticle spinel ferrite catalyst and a web including cellulosic fibers and an optional web-filler. The web-filler can be a modified web-filler which incorporates the spinel ferrite catalyst. The nanoparticle spinel ferrite catalyst can be a nanoparticle manganese-copper-iron oxide catalyst incorporated in the wrapper and/or a tobacco cut filler. Also provided is a smoking article including a cigarette tobacco rod having a wrapper including a web, a web-filler, and a nanoparticle spinel ferrite catalyst, the web-filler optionally supporting the nanoparticle catalyst. A method of making the wrapper and a method of making a smoking article utilizing the wrapper are also provided.

  • Patent number: 7868615
    Abstract: In a method and device for suppressing residual motion artifacts, k-space is divided into a snapshot segment, an alternate sampling segment and a high frequency segment in a phase encoding direction; then phase encoding lines are respectively sampled within each of the segments; and a magnetic resonance image is reconstructed according to the phase encoding lines within k-space.

  • Patent number: 7568485
    Abstract: A system and method is provided for dispersing fine catalyst powders having nanoscale or microscale particles throughout the tobacco rod portion of a cigarette. A source of vacuum is connected to the filter end of a cigarette through a tube that is sealingly engaged with the filter end of the cigarette. The opposite cut filler end of the tobacco rod portion of the cigarette is placed in the proximity of a predetermined amount of the catalyst powder contained in a container. The vacuum is applied to the cigarette filter in an amount and for a period of time that is a function of the size and quantity of the particles to be drawn into and dispersed throughout the tobacco rod portion of the cigarette.
