20110119228 | SELECTIVE FILE SYSTEM CACHING BASED UPON A CONFIGURABLE CACHE MAP - A method for implementing selective file system caching. The method includes receiving I/O requests from an application and comparing each of the I/O requests with a configurable cache map, wherein the configurable cache map controls a selective caching based on an I/O type and a file type. Each of the I/O requests are processed to render caching decisions based on the configurable cache map. Selective caching is then implemented on each of the I/O requests in accordance with the caching decisions. | 05-19-2011 |

20150326601 | ASSESSMENT TYPE-VARIABLE ENTERPRISE SECURITY IMPACT ANALYSIS - A data management service identifies sensitive data stored on enterprise databases according to record classification rules that classify a data record as having a sensitive data type if the data record includes fields matching at least one of the record classification rules. Methods and systems rely on a set of impact factors each having a set of set of value bands representing a range for the impact factor and a corresponding value (between 0 and 1). The factors, ranges, and values all are customizable for an organization. Impact scoring calculations take into account each of the impact factors, and each is weighted to represent a specific risk perception or assessment type. A similar impact scoring is applied to data quality using volume of data as a key attribute of the quality. | 11-12-2015 |

20110020920 | MICROFABRICATED INTEGRATED DNA ANALYSIS SYSTEM - Methods and apparatus for genome analysis are provided. A microfabricated structure including a microfluidic distribution channel is configured to distribute microreactor elements having copies of a sequencing template into a plurality of microfabricated thermal cycling chambers. A microreactor element may include a microcarrier element carrying the multiple copies of the sequencing template. The microcarrier element may comprise a microsphere. An autovalve at an exit port of a thermal cycling chamber, an optical scanner, or a timing arrangement may be used to ensure that only one microsphere will flow into one thermal cycling chamber wherein thermal cycling extension fragments are produced. The extension products are captured, purified, and concentrated in an integrated oligonucleotide gel capture chamber. A microfabricated component separation apparatus is used to analyze the purified extension fragments. The microfabricated structure may be used in a process for performing sequencing and other genetic analysis of DNA or RNA. | 01-27-2011 |

20090035770 | Inline-injection microdevice and microfabricated integrated DNA analysis system using same - Methods and microfluidic circuitry for inline injection of nucleic acids for capillary electrophoresis analysis are provided. According to various embodiments, microfabricated structures including affinity-based capture matrixes inline with separation channels are provided. The affinity-based capture matrixes provide inline sample plug formation and injection into a capillary electrophoresis channel. Also provided are methods and apparatuses for a microbead-based inline injection system for DNA sequencing. | 02-05-2009 |
20100285975 | MICROFABRICATED DROPLET GENERATOR FOR SINGLE MOLECULE/CELL GENETIC ANALYSIS IN ENGINEERED MONODISPERSED EMULSIONS - Provided are microfluidic designs and methods for rapid generation of monodisperse nanoliter volume droplets of reagent/target (e.g., molecule or cell) mix in emulsion oil. The designs and methods enable high-throughput encapsulation of a single target (e.g., DNA/RNA molecules or cells) in controlled size droplets of reagent mix. According to various embodiments, a microfabricated, 3-valve pump is used to precisely meter the volume of reagent/target mix in each droplet and also to effectively route microparticles such as beads and cells into the device, which are encapsulated within droplets at the intersection of the reagent channel and an oil channel. The pulsatile flow profile of the microfabricated pumps provides active control over droplet generation, thereby enabling droplet formation with oils that are compatible with biological reactions but are otherwise difficult to form emulsions with. | 11-11-2010 |
