  • Intelligent multi-scale medical image landmark detection
    Patent number: 10643105
    Abstract: Intelligent multi-scale image parsing determines the optimal size of each observation by an artificial agent at a given point in time while searching for the anatomical landmark. The artificial agent begins searching image data with a coarse field-of-view and iteratively decreases the field-of-view to locate the anatomical landmark. After searching at a coarse field-of view, the artificial agent increases resolution to a finer field-of-view to analyze context and appearance factors to converge on the anatomical landmark. The artificial agent determines applicable context and appearance factors at each effective scale.

  • SYSTEM AND METHOD OF CHEMICAL MECHANICAL POLISHING
    Publication number: 20200101582
    Abstract: A system controls a flow of a chemical mechanical polish (CMP) slurry into a chamber to form a slurry reservoir within the chamber. Once the slurry reservoir has been formed within the chamber, the system moves a polishing head to position and force a surface of a wafer that is attached to the polishing head into contact with a polishing pad attached to a platen within the chamber. A wafer/pad interface is formed at the surface of the wafer forced into contact with the polishing pad and the wafer/pad interface is disposed below an upper surface of the slurry reservoir. During CMP processing, the system controls one or more of a level, a force, and a rotation of the platen, a position, a force and a rotation of the polishing head to conduct the CMP processing of the surface of the wafer at the wafer/pad interface.

  • Career Pivot Intelligence
    Publication number: 20200104781
    Abstract: The technical problem of automatically facilitating a career transition that is a career pivot is addressed by providing a career navigator component in an on-line connection network system. The career navigator is configured to determine that a member's intent is to pivot in their career and, in response, identify, rank, and surface member profiles that indicate the same pivot. The operations for recognizing a pivot intent include maintaining hierarchical occupation taxonomy that can be consulted to determine whether the member's activities on the web site relate to the same or different parent occupations. Once the pivot intent has been recognized, the career navigator identifies those member profiles that indicate the same career transition, and presents those profiles to the pivoting member via a custom-generated user interface.
