  • Patent number: 7973133
    Abstract: 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.

  • Publication number: 20090172655
    Abstract: 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.

  • Publication number: 20080124544
    Abstract: A cable (1) comprises a conductor (3), an insulating layer (2) which forms a self-supporting ceramic layer when exposed to elevated temperatures experienced in a fire, and an additional heat transformable layer (4). The additional layer (4) can be another layer which forms a self-supporting ceramic layer when exposed to fire, or it can act as a sacrificial layer which decomposes at or below the temperature that the insulating layer forms a ceramic. The addition layer can enhance the strength of the layers before, during or after the fire, the structural integrity of the insulting layer (2) after the fire, the resistance of the layers to the ingress of water after the fire, or the electrical or thermal resistance of the layers during and after the fire.

  • Publication number: 20070133321
    Abstract: Improved integrated circuits, memory devices, circuitry, and data methods are described that facilitate the adjustment and reconstruction of signal timing of devices by providing for an interface having inputs and/or outputs that are adjustably delayed. This allows embodiments of the present invention to sense the signal delay and utilize adjustable input or output delays to correct the signal timing relationships such that correctly timed communication signals are received by the internal circuitry of the device. In one embodiment of the present invention, a register is utilized to adjust the timing delay of individual input and/or output signals for the device. This increases the robustness of the device and its resistance to communication or data corruption, allowing larger ranges of environmental conditions and input capacitances of systems or communication busses to be tolerated.
