  • Patent number: 7689602
    Abstract: A data management system or “DMS” provides data services to data sources associated with a set of application host servers. The data management system typically comprises one or more regions, with each region having one or more clusters. A given cluster has one or more nodes that share storage. When providing continuous data protection and data distribution, the DMS nodes create distributed object storage to provide the necessary real-time data management services. The objects created by the DMS nodes are so-called active objects. The distributed object store can be built above raw storage devices, a traditional file system, a special purpose file system, a clustered file system, a database, and so on. According to the present invention, the DMS active object store provides an indexing service to the active objects. In an illustrative embodiment, any object property that has a given attribute is indexed and, as a result, the attribute becomes searchable.

  • Patent number: 7687267
    Abstract: Transfecting biology cells with nucleic acid molecules (DNA, siRNA) is an essential prerequisite in elucidating how genes function in complex cellular context and how their activities could be modulated for therapeutic intervention. Traditionally studies are carried out on a low throughput gene-by-gene scale, which has created a huge bottleneck in functional genomic study and drug discovery. Development of high-throughput cell transfection technology will permit functional analysis of massive number of genes and how their activities could be modulated by chemical or biological entities inside cells. This invention describes design, construction of device and apparatus for high throughput effective cell transfection. Procedures and protocols for using the device and apparatus are also described in the application. Novel methods of using the device in cell-based assays are also disclosed.
