Abstract: A fully-printed sensor chip for measuring prothrombin time of a blood sample. The sensor chip includes a pair of electrodes and a pair of contact pads, each electrically coupled to a different one of the electrodes, printed on the surface of the substrate using conductive ink materials. When a blood sample is placed on the sample chip in contact with both electrodes, an impedance of the blood sample is determined based on a measured impedance between the two contact pads. As the blood sample clots, the impedance value changes and the prothrombin time for the blood sample is determined based on a measurement time of a maximum impedance value. A resistive bridge printed on the substrate surface between the contact pads increases a baseline measurement for the sensor chip to a value within a range that is measurable by lower-cost measurement equipment.

Abstract: A compliance testing system for generating a compliance prediction for a test target. Determinate factors and indeterminate factors associated with a current testing stage of the test target are identified. A test vector for each of the indeterminate factors is generated. A set of matching test vectors for each of the indeterminate factors is determined based on the test vector. The set of matching test vectors are determined using data extracted from at least one profile model. A cumulative factor value is determined for each of the indeterminate factors based on the set of matching test vectors. A first outcome is generated for each of the determinate factors. A second outcome is generated for each of the indeterminate factors, based on the cumulative factor value and the set of matching test vectors. A compliance prediction is generated for the test target based on the first outcome and the second outcome.

Abstract: The present disclosure describes a patent management system and method for remediating insufficiency of input data for a machine learning system. A plurality of data vectors using data are extracted from a plurality of data sources. A user input with respect to an input data context is received, the input data context correspond to a subset of the plurality of data elements. An input vector based on the user input is generated and a set of matching data vectors are determined from the plurality of data vectors based on the input vector. An insufficiency of the input data is determined based on a comparison of a number of matching data vectors with a first pre-determined threshold, and/or a variance with a second pre-determined threshold. Further, the set of matching data vectors are expanded by modifying the input vector when the input data is determined to be insufficient.

Abstract: In a method of installing an expandable stent in a right ventricular outflow tract, a frame of the expandable stent is positioned at a deployed position in the right ventricular outflow tract, the frame including a waist portion, and first and second opposed sealing portions extending from the waist portion. The frame is expanded such that the waist portion expands to a first diameter, the first sealing portion expands to a second diameter larger than the first diameter and into contact with a first portion of an inner surface of the right ventricular outflow tract, and the second sealing portion expands to a third diameter larger than the first diameter and into contact with a second portion of the inner surface of the right ventricular outflow tract, wherein the waist portion is spaced apart from the inner surface of the right ventricular outflow tract at the deployed position.

Abstract: An expandable stent for implantation in a right ventricular outflow tract includes a frame having a waist portion that expands to a deployed size having a first diameter, first and second sealing portions extending in opposite directions from the waist portion and expanding radially outward of the waist portion. The first and second sealing portions are sized to seal against first and second portions of the inner surface of the right ventricular outflow tract at the deployed position over a range of sizes of expansion larger than the first diameter. A band is secured to the waist portion of the frame, restricting expansion of the waist portion substantially beyond the first diameter, such that the waist portion is configured to be spaced apart from the inner surface of the right ventricular outflow tract at the deployed position.

Abstract: The present disclosure receives input signals from different sources to fill gaps in a desired heat score signal. Received input signals are categorized to match to a desired category of the desired signal. The various signals are represented in vector format using category tags. There are different latencies for each input signal that are aligned in time with the desired signal. The match to the desired signal varies from the input signals so that each desired signal's contribution during the gap is weighted accordingly. A composite signal is formulated from the time-adjusted and weighted input signals to fill the gap in the desired signal. Over time, the weighting and time-adjustment for each input signal can be modified with a machine learning algorithm that takes the approximation during the gap and compares it later with the actual data once the gap is filled.

Abstract: An expandable docking station frame includes a waist portion, a sealing portion connected to the waist portion, and a retaining portion connected to the sealing portion. The sealing portion is expandable radially outward of the waist portion to provide a seal against a first location of an inner surface of a circulatory system at a deployed position over a range of sizes of expansion. The retaining portion is expandable radially outward to engage a second location of the inner surface of the circulatory system at the deployed position, to retain the docking station at the deployed position in the circulatory system. When the expandable docking station frame is in an expanded and unconstrained state, the sealing portion and the retaining portion are joined by a concave profile portion radially inward of each of a first outermost diameter of the sealing portion and a second outermost diameter of the retaining portion.

Abstract: Systems and methods are provided for utilizing rules for placement of objects in storage in a manner that improves retrieval times relative to a default ordering utilized by an object storage system. For example, a request to store an object in a persistent storage of a data storage system may be received, metadata associated with the request may then be parsed to identify a signal for placement of the object within the persistent storage, and a rule may be identified for placement of objects associated with that signal, such as by indicating a desired grouping or ordering of objects associated with the signal. A particular storage location for the object may then be determined within the persistent storage based at least in part on the signal, the rule, and previously determined storage locations of one or more other data objects associated with the signal.
