A device and method for inspecting and measuring weld defects in a cylindrical wall of a cylindrical conduit. The device can include an inspection head forming a probe having a proximal end and a distal end along its longitudinal axis, and of which a first side called “inner side” is provided with at least one ultrasound wave transducer. The inspection head can include a second side, called “outer side” opposite the first side that has a curved surface in the form of a cylinder fraction, and wherein the curved surface of the second side has outward facing convexity. The wave transducer can be formed of a series of juxtaposed elements, each element being both a transmitter and receiver, wherein a surface of the series is curved and in the form of a cylinder fraction, and wherein the surface of the series has outward facing concavity. |

Method and controller for administering recommended insulin dosages to a patient
A method of administering insulin includes receiving scheduled blood glucose time intervals and obtaining blood glucose data of a patient that includes blood glucose measurements, blood glucose times, and insulin dosages previously administered by the patient. The method also includes applying a set of filters to identify which of the blood glucose measurements associated with at least one of the scheduled time intervals are usable and which of the blood glucose measurements associated with the at least one scheduled time interval are unusable. The method also includes aggregating the blood glucose measurements associated with the at least one scheduled time interval identified as usable to determine a representative aggregate blood glucose measurement and determining a next recommended insulin dosage for the patient based on the representative aggregate blood glucose measurement and the insulin dosages previously administered by the patient. |

Systems and methods for optimal health assessment and optimal preventive program development in population health management
Various health management systems may benefit from tools for appropriate identification of target patients. For example, various population health management approaches may benefit from systems and methods for optimal health assessment and optimal preventative program development. A method can include obtaining a simple risk measure score for a patient. The method can also include obtaining an evidence-based score for the patient. The method can further include comparing the simple risk measure score to the evidence-based score. The method can additionally include identifying the patient as a target for preventative medicine based on a discrepancy revealed by the comparison. |

Deduplication of medical concepts from patient information
Mechanisms are provided to implement a patient summary generation engine with deduplication of instances of medical concepts. The patient summary generation engine parses a patient electronic medical record (EMR) to extract a plurality of instances of a medical concept, at least two of which utilize different representations of the medical concept. The patient summary generation engine performs a similarity analysis between each of the instances of a medical concept to thereby calculate, for a plurality of combinations of instances of the medical concept, a similarity metric value. The patient summary generation engine clusters the instances of the medical concept based on the calculated similarity metric values for each combination of instances in the plurality of combinations of instances of the medical concept to thereby generate one or more clusters, and select a representative instance of the medical concept from each cluster in the one or more clusters. The patient summary generation engine generates a summary output of the patient EMR comprising the selected representative instances of the medical concept from each cluster. |
