  • SENSITIVE DATA EXTRAPOLATION SYSTEM
    Publication number: 20210026982
    Abstract: A content analysis system of an information management system can analyze data for one or more data governance tasks. The content analysis system can reduce the overhead on the information management system when identifying sensitive data by analyzing a portion of the data in the file without analyzing the entirety of the file. The content analysis system may reduce overhead by analyzing a portion of files that include structured data. If the portion of the file that includes structured data does not include sensitive data, it is often the case that the entire file excludes sensitive data. Thus, overhead can be reduced by analyzing the portion of the file instead of the entire file. Further, the content analysis system can modify an information management job based on the determination of the inclusion of sensitive data to comply with data protection and privacy rules.

  • Mist fabrication of quantum dot devices
    Patent number: 8222061
    Abstract: An example quantum dot (QD) device comprises a QD layer on a substrate, and may be fabricated by aerosol deposition, for example by mist deposition. An example approach includes providing a liquid precursor including QDs dispersed in a liquid carrier, generating a mist of droplets of the liquid precursor, directing the droplets towards the substrate so as to form a liquid precursor film on the substrate, and removing the liquid carrier from the liquid precursor film to form the quantum dot layer on the substrate. Example devices include multi-color QD-LED (light emitting diode) displays, and other devices.
