  • Publication number: 20200085571
    Abstract: The invention provides methods, devices and systems for delivering, positioning and/or repositioning an expandable prosthetic heart valve in a patient's heart chamber. At least one non-looped wire and looped wire pair is operatively connected with an expanded prosthetic heart valve that is collapsed within a delivery catheter lumen having its distal end positioned in the subject heart chamber. The collapsed prosthetic heart valve is translated through the delivery catheter lumen to and out of its distal end where the prosthetic heart valve expands to a working configuration. The wire(s) of the non-looped and looped wire pair may be manipulated by pulling proximately or pushing distally to position or reposition the expanded prosthetic stent into position, then released from connection with the positioned stent and withdrawn from the patient.

  • Publication number: 20200092588
    Abstract: A method modifies how content is broadcast based on the tone and format of the content. One or more processors retrieve a set of rules that describe a tone and format for proposed content that is to be broadcast to an intended target, and determine whether the proposed content conforms to the set of rules. In response to determining that the proposed content does not conform to the set of rules, the processor(s) modify how the proposed content is broadcast to the intended target. The processor(s) generate an enriched content of the modified content by applying, to the modified content, content metatags that describe a content of the modified content, and then analyze the enriched content to calculate a trustworthiness index (TI) for the enriched content. The processors further modify how content is broadcast to the intended target based on the TI of the enriched content.

  • Publication number: 20200069423
    Abstract: A device and method for predictably and controlling the collapsing of a collapsible and expandable stent for subsequent translation through a delivery sheath lumen to an anatomical target such as a heart valve or intravascular location for expansion and implantation. The loading device defines in inner lumen comprising a successively decreasing, from the proximal to the distal direction, inner diameter alternating between two sections of decreasing diameter and two sections of constant diameter until reaching the inner diameter of the delivery sheath. A fluid-filled reservoir is provided at the proximal end of the loading device that is configured to provide moisture or wetting for materials associated with or attached to the stent that require moisture retention. Thus, as the stent is being collapsed with the loading device, at least a portion of the stent may be immersed in the fluid reservoir to preserve the subject material.

  • Patent number: 10516902
    Abstract: A method adjusts a broadcasting system according to properties of content being broadcast. One or more processors receive a proposed content that is designed to be a component of an electronic broadcast by a broadcast system. The processor(s) determine a broadcast analysis pattern (BAP) for the proposed content, where the BAP describes the proposed content and an intended target of the electronic broadcast. The processor(s) retrieve a set of rules that describe a tone and format for particular content that is broadcast to the intended target, and determine whether the proposed content conforms to the set of rules. In response to determining that the proposed content does not conform to the set of rules, the processor(s) adjust the broadcasting system, where adjusting the broadcasting system modifies how content is broadcast to the intended target.

  • Patent number: 10489126
    Abstract: Techniques are disclosed for automating GUI development from a GUI screen image that includes text information and one or more graphic user interface components. The GUI screen image is analyzed to extract text information and to identify the UI components included in the GUI screen. One or more text regions in the GUI screen image are detected and are replaced with placeholders. Images of one or more graphic user interface components in the GUI screen are extracted from the GUI screen image and are classified using a machine learning-based classifier. A GUI model is generated for the GUI based upon the classification results, locations of the one or more text regions, and locations of the one or more graphic user interface components. The generated model can then be used to generate one or more implementations (e.g., executable code) of the GUI, possibly for various platforms in different programming languages.
