| 20090160944 | Camera flash module and method for controlling same - An auto-exposure algorithm for controlling a camera flash uses image processing to identify important areas of the image affected by the flash, while disregarding highly reflective/illuminated areas and uses a ND filter to linearize the flash triggering with highly reflective scenes. The camera flash is controlled by the auto-exposure algorithm in two stages: | 06-25-2009 |

| 20110276702 | Tunneling apparatus and method for client-server communication - An HTTP tunneling service is described for creating a tunneled path between a client and a server (e.g., over a firewall or other data/protocol filtering device). According to one embodiment of the invention the client sends the server an initial request to open a preliminary socket connection which includes a secure client ID previously assigned to the client. The server opens the preliminary socket connection, generates a random client ID and transmits the random client ID to the client. The preliminary socket connection is then closed. The client then sends a second request to open a second socket connection using both the unique ID and the secure client ID for authentication purposes. | 11-10-2011 |

| 20090172655 | System, method and article of manufacture for using shadow installations of software modules during distributed system upgrade - A method, system and article of manufacture for upgrade of a software module executed in a distributed software computer system using shadow installations of software modules for minimum downtime. A first software module is executed on a first host and a second software module is executed on a second host, the two software modules in communication with each other. Target release of the first software module and a local release of the second software module are installed and deployed on the first host during the execution of the first software module. The first software module is switched to the target release in communication with the local release of the second software module. The communication with the second software module is reestablished after the upgrade. | 07-02-2009 |
| 20090208452 | Inhibitor of Endogenous Human Interferon-Gamma - The invention relates to an inhibitor of endogenous human interferon-gamma (hIFN-ϝ) in autoimmune diseases, especially in multiple sclerosis. More precisely, the invention relates to inactivated protein derivatives of the hIFN-ϝ with preserved affinity to the hIFN-ϝ receptor. The derivatives represent genetically modified variants of hIFN-ϝ where the C-terminal part of the molecule is either deleted or replaced with a polypeptide sequence of another human protein and a recombinant hIFN-ϝ inactivated by physical or chemical methods. | 08-20-2009 |

The derivatives represent genetically modified variants of hIFN-ϝ, where the C-terminal part of the molecule is either deleted or replaced with a polypeptide sequence of another human protein and a recombinant hIFN-ϝ, inactivated by physical or chemical methods. | 06-24-2010 |
| 20110135602 | SUPPERSSOR OF THE ENDOGENOUS INTERFERON-GAMMA - The invention relates to suppressor of the endogenous human interferon-gamma (hlFN-γ) applicable in treatment of diseases associated with impaired activity of endogenous hlFN-γ, especially autoimmune diseases and for prevention of graft arteriosclerosis and rejection of organs in allograft transplanted patients. It is based on inactive analogues of the hlFN-γ with pre-served affinity to the hlFN-γ receptor, genetically modified in the domain responsible for triggering the signal transduction pathway. | 06-09-2011 |
| 20110218325 | Inhibitor of Endogenous Human Interferon-Gamma - Inactivated protein derivatives of the hIFN-γ that preserve affinity to the hIFN-γ receptor are useful in the treatment of autoimmune diseases, especially multiple sclerosis. | 09-08-2011 |

| 20090133480 | Methods and device for fast creation of fluid interfaces and use of this device for determination of liquid-liquid and liquid-gas interfacial properties - The invention proposes new methods for fast fresh surface formation of a drop or bubble of a test fluid and a device to realize the new methods to determine the dynamic or equilibrium surface/interfacial tension (ST/IFT) of this liquid. The methods are implemented by means of a single device which is used both for dynamic and equilibrium measurements of the ST/IFT. Depending on the method, the determination of the ST/IFT can be performed either by Axisymmetric Drop Shape Analysis (ADSA) or Capillary Pressure Method (CPM) or both. In addition, with this device the Drop Volume Method and Stopped Jet Method can be realized, which has been modified and improved with the proposed invention in comparison with the known methods. The combination of several methods for creating a fresh surface and of two techniques for determining ST/IFT in a single device allows choosing the most suitable method for a given fluid system considering the system properties and desired time range. The proposed device consists of the following components: | 05-28-2009 |

| 20100157822 | SERVICE ACCOUNTING METHOD AND APPARATUS FOR COMPOSITE SERVICE - A system for an accounting infrastructure, including monitoring and reporting, for individual services within a composite service. An accounting engine integrates with the composite service to monitor components and parameters of at least one service in the composite service, to provide reporting on the measurements and statistics associated therewith over time. The accounting engine aggregates data for components and services. One example provides the accounting infrastructure as an object-oriented program model, instantiating statistics as objects. The reporting distinguishes each statistic allowing analysis and optimization of processes and services. | 06-24-2010 |
