| 20080275216 | Fluorous Capping Reagents and Methods for Peptide Purification - Aspects of the present invention relate to compounds for preparing fluorocarbon compounds, methods for preparing fluorocarbon compounds, and methods for purifying a mixture of compounds. One aspect of the present invention relates to a trivalent iodonium fluorocarbon. The trivalent iodonium fluorocarbon compound of the invention is useful for attaching a fluorocarbon group to a compound that has a nucleophilic functional group. Another aspect of the present invention relates to a method of preparing a trivalent iodonium fluorocarbon. Another aspect of the present invention relates to a method of preparing a fluorocarbon by treating a compound bearing a nucleophilic functional group with a trivalent iodonium fluorocarbon compound. Another aspect of the present invention relates to a method or purifying a mixture comprising a first and a second compound by treating the mixture with a trivalent iodonium fluorocarbon to attach a fluorocarbon group to the second compound leaving the first compound unchanged, and purifying the mixture by fluorous-phase purification. | 11-06-2008 |
| 20090214439 | Fluorinated Carbohydrates and Their Use in Tumor Visualization, Tissue Engineering, and Cancer Chemotherapy - The present invention relates to fluorine-containing monosaccharides that are useful for forming extracellular fluorinated glycoconjugates. Methods of forming extracellular fluorinated glycoconjugates comprise the steps of contacting a cell with a fluorine-containing monosaccharide, and incubating the cell under conditions whereby the cell internalizes the fluorine-containing monosaccharide, or a derivative thereof, on the surface of the cell. The present invention also relates to the use of a fluorine-containing monosaccharide in cellular imaging using fluorine NMR. The invention additionally relates to the use of fluorine containing monosaccharides in the treatment of cancer and inflammatory disease. | 08-27-2009 |
| 20090326196 | Proteins Containing a Fluorinated Amino Acid, and Methods of Using Same - One aspect of the invention relates to a polypeptide comprising at least one fluorinated amino acid. Another aspect of the invention relates to a method for modifying a first polypeptide, comprising replacing at least one amino acid in said first polypeptide with a fluorinated amino acid, thereby producing a second polypeptide with increased stability relative to said first polypeptide. | 12-31-2009 |
| 20100286250 | FLUORINATED LIPIDS AND METHODS OF USE - The invention provides methods and compounds for delivering agents to cells. The compounds can include a fluorinated lipid, a linker, and an agent for delivery to a cell. | 11-11-2010 |

| 20090066993 | REMOTE PRINT DEVICE MANAGEMENT - A method and system for print device control includes a set of networked print devices that communicate with an application server, and a separate hosted server that sends commands to the application server. A firewall restricts communication between the hosted server and the application server, but the hosted server may deliver commands to the application server in response to queries that the hosted server receives from the application server. The application server then identifies which of its print devices are relevant to each command, and the application server delivers the commands to the relevant print devices for implementation. | 03-12-2009 |
| 20090066994 | METHOD AND SYTEM FOR REMOTE MANAGEMENT OF PRINT DEVICES - A method of controlling a print device using an instruction corresponding to a command received from a remote location. A second server may transmit a query directed to a first server. The second server may be prevented from receiving unauthorized communication from the first server by a firewall. If the first server has a relevant command available, the second server may receive a response to the query. The response may include the relevant command. The second server may determine a print device for which the command is relevant. An instruction corresponding to the relevant command may be sent from the second server to the print device. Communication between the print device and the second server may not be restricted by the firewall. The printing device may implement the instruction. If the first server does not have a relevant command available, the transmitting may automatically repeat until the first server has a relevant command available. | 03-12-2009 |

| 20080313639 | POLICY BASED SCHEDULING OF SOFTWARE APPLICATIONS - A method and apparatus for using policies to limit resource usage by software applications is disclosed herein. The policies define rules that specify a maximum amount of a resource that a particular application is allowed to use given the current state of the computer system, in one embodiment. The state can be defined based on conditions such as user activity, resource usage, time of day, etc. A scheduler monitors the computer system and the application and enforces the policies to control the resource usage of each application. If the scheduler determines that an application has been using more of a particular resource than is allowed then the scheduler takes some action to reduce resource usage until actual resource usage is at or below allowed resource usage. Each application has its own set of policies associated that allow the application to define rules to limit resource usage, in one embodiment. | 12-18-2008 |
