  • Publication number: 20100287031
    Abstract: Selecting replacement user devices involves tracking user interactions with an apparatus on an ongoing basis and storing usage pattern data derived from the user interactions. A user-generated request to replace the apparatus with a different apparatus is received, causing the usage pattern data to be compared with features of available devices. A listing of recommended devices selected from the available devices is rendered on the apparatus in response to the request.

  • Publication number: 20070006008
    Abstract: An improved system and method for displaying information on an electronic device when the electronic device is in an idle mode. The present invention includes an idle display program for exhibiting information on a display when the module is in idle mode, at least one plug-in program, and a layout manager program. The layout manager program is separate from the least one plug-in program and can be replaced, as necessary, with other layout manager programs located either within the electronic device or external to the electronic device.

  • Publication number: 20060111276
    Abstract: Cidofovir-based compounds having an amino acid, dipeptide or tripeptide attached to a cidofovir or cyclic cidofovir framework. The compounds show enhanced oral bioavailability and increased binding to the PepT1 transporter. The present invention also provides compositions and methods for treating virus infections, and a method of preparing cidofovir.

  • Publication number: 20060065604
    Abstract: The present invention provides for Troika acids attached to a macroporous resin and Methods of preparing the same, including direct attachment of a Troika acid, and attachment of a Troika acid precursor followed by generation of the Troika acid in situ. Methods of functionalizing a resin to facilitate attachment are also described. Multiple Troika acids, comprising a pair of Troika acids joined together are described. Synthetic routes to both microporous and macroporous resins modified by introduction of a suitable Troika-type acid have been designed and validated. In a preferred embodiment, a macroporous Troika resin removes Cu2+ and Ni2+ from aqueous solution with high affinity, and is selective against Mg2+ or Ca2+. The materials of the present invention have advantages for metal removal from power plant waste water.

  • Patent number: 6313475
    Abstract: An ion beam generator includes an ion beam source for generating an ion beam, an acceleration/deceleration column for selectably accelerating or decelerating ions in the ion beam to desired energies, a source filter positioned between the ion beam source and the acceleration/deceleration column for removing first undesired species from the ion beam, and a mass analyzer positioned downstream of the acceleration/deceleration column for removing second undesired species from the ion beam. The ion beam generator supplies an energetic ion beam having a low level of energy and mass contaminants. The ion beam generator may be utilized in an ion implanter.
