  • Publication number: 20240112110
    Abstract: The present invention relates to systems and methods for ingesting of raw client data into a supply chain optimization system. The client enterprise data system (EDS) provides raw data, typically in tabular format across many files, to a data management module of the optimization system. This data is then profiled. and a set of mapping AI models is applied to the profiled data. Each of the plurality of mapping AI models corresponds to a single input feature of the optimization model. As the mapping models are applied, a live preview is generated. This live preview is reviewable by a human operator, and human input can be provided. When there is input, the individual mapping model is updated (without impacting the other mapping models), and a new live preview for that given feature is generated. The resulting standardized feature set may be consumed by the supply chain optimization model.

  • Patent number: 5776068
    Abstract: Apparatus is provided for high frequency ultrasound examination of the anterior segment of a patient's eyes. A liquid bath is established about a first eye of the patient to be examined. A fixed ultrasound transducer is placed in contact with the liquid bath and directs the beam of ultrasound energy to the first eye and receives echoes of the ultrasound energy. A fixation source is juxtaposed to the second eye of the patient and displays a fixation target. A controller operates the fixation source to move the fixation target relative to the second eye, while the patient moves the second eye so as to remain focused on the fixation target. The movement of the second eye causes the first eye to move concurrently and enables relative movement between the beam of ultrasound energy and anterior segments of the first eye, while maintaining near orthogonality between the ultrasound beam and the surface of the eye.
