  • Patent number: 10643988
    Abstract: The present disclosure describes exemplary configurations and arrangements for various intelligent diodes. The intelligent diodes of the present disclosure can be implemented as part of electrostatic discharge protection circuitry to protect other electronic circuitry from the flow of electricity caused by electrostatic discharge events. The electrostatic discharge protection circuitry dissipates one or more unwanted transient signals which result from the electrostatic discharge event. In some situations, some carrier electrons and/or carrier holes can flow from intelligent diodes of the present disclosure into a semiconductor substrate. The exemplary configurations and arrangements described herein include various regions designed collect these carrier electrons and/or carrier holes to reduce the likelihood these carrier electrons and/or carrier holes cause latch-up of the other electronic circuitry.

  • Publication number: 20200137012
    Abstract: Software for online active learning receives content posted to an online stream at a website. The software converts the content into an elemental representation and inputs the elemental representation into a probit model to obtain a predictive probability that the content is abusive. The software also calculates an importance weight based on the elemental representation. And the software updates the probit model using the content, the importance weight, and an acquired label if a condition is met. The condition depends on an instrumental distribution. The software removes the content from the online stream if a condition is met. The condition depends on the predictive probability, if an acquired label is unavailable.

  • Publication number: 20200042395
    Abstract: In an embodiment, described herein is a system and method for discovering backups of a database running on a database host, for use by a centralized backup system to validate backup compliance. A report agent executing on the database host can implement a discovery process configured to gather metadata for the backups of the database from a number of dynamic performance views of the database. The metadata is recorded in a control file of the database, and can include one or more commands used by the backup tool to create the backups. The report agent can categorize the metadata into one or more groups based on the backup commands, map backup files associated with each backup to that backup, create a backup report to describe the mapping information and additional information for each backup, and send the backup report to the centralized backup system.
