  • Techniques for identifying acoustic biomarkers in left ventricular assist device recipients
    Patent number: 11931562
    Abstract: Disclosed are systems and techniques for determining an acoustic biomarker. For example, a precordial sound recording that includes at least a first sound component corresponding to a heart and a second sound component corresponding to a left ventricular assist device (LVAD) can be obtained. At least a portion of the second sound component corresponding to the LVAD can be filtered from the precordial sound recording to yield a filtered precordial sound recording. Based on the filtered precordial sound recording, at least one acoustic biomarker can be determined.
    Type: Grant

  • Apparatus and method for deploying analytics
    Patent number: 10489867
    Abstract: A location where to deploy an analytic is determined. The location is at the cloud or at the site of the industrial machine. The analytic is configured to process data from an industrial machine. The analytic is obtained and is configured to communicate with one or more connectors. A first selected one of the one or more connectors is configured to communicate with a database. The analytic is configured so as to be interchangeable and operable at the cloud or at the site of an industrial machine. The analytic is then deployed at one or more of the cloud or the site of the industrial machine.

  • Apparatus and Method for Sorting Time Series Data
    Publication number: 20180173740
    Abstract: At the cloud, time series data is received from at least one industrial machine. The time series data is sensed by at least one sensor at the at least one industrial machine and the data arrives out of time-order. The data includes a time indicator of when the data was created. At the cloud, the data is arranged to be in time-order. At the cloud, an analytic is executed using the arranged time series data. In examples, the time order is from the earliest to the latest data.
