  • Patent number: 7440981
    Abstract: Systems and methods for replicating replicas in a sync community. Each replica in the sync community stores knowledge that represents changes the replica is aware of. Because each replica has its own knowledge, each replica does not need to know how many replicas are in the sync community or the topology of the sync community. By sending the knowledge with a request for changes, a replicating replica can enumerate the changes to replicate by comparing its knowledge with the received knowledge. After replication, the knowledge is updated. Knowledge may also include made-with-knowledge change IDs that permit each resolution to identify what a replica was aware of when a particular change was made. The made-with-knowledge values are used to detect conflicts during replication.

  • Publication number: 20080013257
    Abstract: An anode for an electrolytic capacitor is described. The anode is of a valve metal in powdered form, for example tantalum powder, that has been pressed into a pellet and sintered under a vacuum at high temperatures. Preferably, a poly(alkylene)carbonate binder is used to promote cohesion with the pressed powder body. The binder adds green strength to the pressed body and helps with powder flow before pressing. The poly(alkylene)carbonate binders are superior in that they leave virtually no residual carbon behind when burnt out during the sintering process. The pressed valve metal powder structure is then anodized to a desired voltage in a formation electrolyte to form a continuous dielectric oxide film on the sintered body as well as a terminal lead/anode lead weld extending therefrom.

  • Patent number: 7200583
    Abstract: The invention provides a method and apparatus for selecting desired attributes for system configuration. The invention uses one or more rule sets to define rules that are met when a configuration is valid. A rule set may specify the interrelation of attribute values within a product or between two or more products. If the combination of attribute values that specify a product conform to at least one rule in each of the rule sets that apply to that product, that combination of attribute values is considered to specify a valid product. If the combination of attribute values that specify all of the products of an assembly conform to at least one rule in each of the rule sets that apply to that assembly, that combination of attribute values is considered to specify a valid assembly.

  • Patent number: 7171434
    Abstract: A storage virtualization system for accessing at least one storage device for a virtual logical unit (VLUN) from at least one host. The system includes at least one upstream processing element (UPE) which is adapted for coupling to a corresponding host server. The system is further adapted for coupling to at least one storage device. The controller also includes a primary central processing element (CPE) that can be configurably coupled to the UPEs. The primary CPE permits data transfer to occur between a host and a storage device via the corresponding UPE. The controller further includes a backup CPE that can be configurably coupled to the UPEs. The backup CPE is configurable to permit the data transfer when the primary CPE becomes unavailable.

  • Publication number: 20060107251
    Abstract: A description of the hierarchically-structured document is accessed and converted into an early-bound object having at least some of the same properties as the hierarchically-structured document, and having at least some of the methods that may be performed on the hierarchically-structured document. When a function call is placed to the early-bound object, the early-bound object causes the appropriate corresponding changes to be affected on the hierarchically-structured document while maintaining change tracking information for the document. This reduces the difficulty when drafting source code for a program that interfaces with hierarchically-structured documents that can have varying structures and may be governed by complex change tracking rules.

  • Publication number: 20060013942
    Abstract: A method for improving the electrical conductivity of a substrate of metal, metal alloy or metal oxide comprising directing a high energy beam of doping ions from Group VIII onto a substrate. This causes an intermixing of the doping ions with the native oxide of the substrate metal or metal alloy. The native oxide layer is changed from being electrically insulating to electrically conductive. The high-energy beam is an ion beam from a high-energy ion source. The thusly-treated substrate is useable in the manufacture of electrodes for devices such as capacitors and batteries.
