  • Patent number: 9100329
    Abstract: A device receives traffic; identifies an address associated with the traffic; determines whether the address is associated with an aggregate interface, the aggregate interface being associated with a first port and a second port. The first port corresponds to a first node in a first state, that indicates that the first node is available to forward the traffic, and the second port corresponds to a second node in a second state, that indicates that that the second node is not available to forward the traffic. The device transmits the traffic to the first node via the first port and to the second node, via the second port, when the address is associated with the aggregate interface. Transmitting the traffic enables the second node to forward the traffic when the first node changes from the first state to the second state.

  • Publication number: 20150007274
    Abstract: An authentication and authorization plug-in model for a cloud computing environment enables cloud customers to retain control over their enterprise information when their applications are deployed in the cloud. The cloud service provider provides a pluggable interface for customer security modules. When a customer deploys an application, the cloud environment administrator allocates a resource group for the customer's application and data. The customer registers its own authentication and authorization security module with the cloud security service, and that security module is then used to control what persons or entities can access information associated with the deployed application. To further balance the rights of the various parties, a third party notary service protects the privacy and the access right of the customer when its application and information are deployed in the cloud.

  • Patent number: 8896335
    Abstract: An apparatus controls a temperature of a device by circulating a fluid through a heat sink in thermal contact with the device. The apparatus includes an adjustable cold input, which inputs a cold portion of the fluid having a first temperature, and an adjustable hot input, which inputs a hot portion of the fluid having a second temperature higher than the first temperature. The apparatus further includes a chamber, connected to the cold input and hot input, in which the cold and hot portions of the fluid mix in a combined fluid portion that impinges on the heat sink. The combined fluid portion has a combined temperature that directly affects a temperature of the heat sink. The cold input and hot input are adjusted to dynamically control the combined temperature, enabling the heat sink temperature to compensate for changes in the device temperature, substantially maintaining a set point temperature of the device.

  • Patent number: 8893118
    Abstract: Embodiments of the present invention address deficiencies of the art in respect to application migration and provide a novel and non-obvious method, system and computer program product for application migration through migratable units. In one embodiment, an application migration method can include decomposing an application migration into a plurality of migratable units (MUs). The MUs can be prioritized for migration to a target platform. Thereafter, each of the MUs can be migrated in an order defined by the prioritization. Finally, a stateful wizard can be provided which can reduce the complexity of the migration by providing a dashboard to the migration process.

  • Publication number: 20140302486
    Abstract: A detection probe for detecting single base mutations or alterations in a double stranded target nucleic acid molecule is provided. In some aspects, the detection probe may include a double-stranded probe nucleic acid molecule having a first end and a second end; at least one probe initiation toehold at the first end; at least one substance capable of emitting a detectable signal at the second end; and optionally, at least one dissociation toehold at the second end. The detection probe is designed to hybridize with a double stranded target nucleic acid in a reaction which proceeds at approximate thermodynamic equilibrium (?G?0) when no single base mutations or alterations are present in the double stranded target nucleic acid molecule. The probe may be used in detection systems and methods to identifying the presence or absence of one or more single base mutations or alterations in a double-stranded nucleic acid target molecule.

  • Patent number: 8572694
    Abstract: An approach to handling integrated security roles is presented. An upstream application includes one or more role-mapping requirements that correspond to an upstream security role and a downstream security role. The upstream security role is expanded by adding an upstream security role identifier in a downstream application's role-mapping table or by adding upstream user-to-role mappings to a downstream application's role-mapping table. When an upstream security role is expanded, a user assigned to the upstream security role automatically has access to role-mapped downstream applications.
