  • Publication number: 20210327596
    Abstract: Methods and systems for selecting a treatment for a patient. The system extracts an incidental finding from a record associated with a patient and an associated follow-up recommendation. The system then determines whether any inconsistencies exist between the follow-up recommendation from the report and a follow-up recommendation prescribed by institutional or administrative guidelines. Any inconsistencies may then be resolved to guarantee an appropriate workflow for patient care.

  • Patent number: 11152861
    Abstract: This disclosure relates to a multiphase converter design with multi-path phase management circuit and output logic. The phase management circuit and output logic can be employed to implement phase adding and shedding operations based on input and output current information and based on control signals for a power stage of the converter. In some examples, the design employs an estimate of an average output current based on a current at an input of the converter for phase control. In additional examples, the design employs cycle-by-cycle current limit and maximum duty-cycle signals to enable phase quickly during load transient. In further examples, the design employs low input and output-current sensed signals for efficient phase shedding and power saving. The design herein improves an overall accuracy of phase adding and shedding, load transient response performance, an operational efficiency and thermal performance of multiphase converter.

    Abstract: A database merger method (20) merges two or more anonymized healthcare databases (X, Y). Each anonymized healthcare database has personally identifying information anonymized including having medical care units replaced by medical care unit placeholders. In the database merger method, statistical patient feature distributions are computed for medical care unit placeholders in the anonymized healthcare databases. Medical care unit placeholders in different anonymized healthcare databases are matched by matching corresponding statistical patient feature distributions for the respective medical care unit placeholders. Patients in different anonymized healthcare databases are matched. The patient matching is performed within matched pairs of medical care unit placeholders to improve computational efficiency.
