  • Patent number: 11916927
    Abstract: A system and method for accelerating a disposition of a digital dispute event includes routing a digital dispute event to one of a plurality of distinct machine learning-based dispute scoring models; computing, by the one of the plurality of distinct machine learning-based dispute scoring models, a preliminary machine learning-based dispute inference based on one or more features extracted from the digital dispute event, wherein the preliminary machine learning-based dispute inference relates to a probability of the subscriber prevailing against the digital dispute event based on each piece of evidence data of a service-proposed corpus of evidence data being available to include in a dispute response artifact; and generating the dispute response artifact based on the digital dispute event, wherein the generating includes installing one or more obtainable pieces of evidence data associated with the digital event into one or more distinct sections of the dispute response artifact.

  • Patent number: 8082120
    Abstract: A method and hand-held scanning apparatus for three-dimensional scanning of an object is described. The hand-held self-referenced scanning apparatus has a light source for illuminating retro-reflective markers, the retro-reflective markers being provided at fixed positions on or around the object, a photogrammetric high-resolution camera, a pattern projector for providing a projected pattern on a surface of the object; at least a pair of basic cameras, the basic camera cooperating with light sources, the projected pattern and at least a portion of the retro-reflective markers being apparent on the 2D images, a frame for holding all components in position within the hand-held apparatus, the frame having a handle, the frame allowing support and free movement of the scanning apparatus by a user.

  • Publication number: 20080009695
    Abstract: A system and method for beginning an exam procedure in multiple modality systems during the performance of a physiology procedure. Upon the initiation of a physiology procedure in a physiology workstation, the physiology workstation automatically generates an exam notification message to each modality system required during the performance of the physiology procedure. Upon receiving the start exam notification message, each modality system automatically generates a patient information query back to the physiology workstation requesting patient information and exam information. The physiology workstation returns identical patient information and exam information to each of the modality systems, thereby ensuring that each of the modality systems is operating utilizing the same patient information and exam information.
