  • Patent number: 10264992
    Abstract: Physiological monitoring can be provided through a lightweight wearable monitor that includes two components, a flexible extended wear electrode patch with sewn electrodes and a reusable monitor recorder that removably snaps into a receptacle on the electrode patch. The monitor sits centrally on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline, with its unique narrow “hourglass”-like shape, significantly improves the ability of the wearable monitor to cutaneously sense cardiac electrical potential signals, particularly the P-wave and the QRS interval signals indicating ventricular activity in the ECG waveforms. In particular, the ECG electrodes on the electrode patch are tailored to be positioned axially along the midline of the sternum for capturing action potential propagation in an orientation that corresponds to the aVF lead used in a conventional 12-lead ECG that is used to sense positive or upright P-waves.

  • Patent number: 10264993
    Abstract: A system and methods for scanning and analyzing one or more characteristics of a sample utilizing electromagnetic radiation is described. More particularly, the system and methods utilize an electromagnetic radiation source connected to a transmitter and an analyzer connected to a receiver. A sample to be analyzed is placed between the transmitter and receiver and a frequency sweep of electromagnetic radiation is transmitted through the sample to create a series of spectral data sets, which are developed into a composite spectrogram by the analyzer and processed to determine one or more characteristics of the sample. A magnetic field can alternatively be applied around the transmitter, receiver and sample to enhance some characteristic analysis applications and to make other characteristic analysis applications possible. Samples include inert and living items and the characteristics include a wide variety of different applications.

  • Patent number: 10264994
    Abstract: A method for performing free breathing pixel-wise myocardial T1 parameter mapping includes performing a free-breathing scan of a cardiac region at a plurality of varying saturation recovery times to acquire a k-space dataset; generating an image dataset based on the k-space dataset; and performing a respiratory motion correction process on the image dataset. The respiratory motion correction process comprises selecting a target image from the image dataset, co-registering each image in the image dataset to the target image to determine a spatial alignment measurement for each image, and identifying a subset of the image dataset comprising images with the spatial alignment measurement above a predetermined value. Following the respiratory motion correction process, a pixel-wise fitting is performed on the image dataset to estimate T1 relaxation time values for the cardiac region. Then, a pixel-map of the cardiac region is produced depicting the T1 relaxation time values.

  • Patent number: 10265029
    Abstract: Systems and methods for generalized precursor pattern discovery that work with a wide range of biomedical signals and applications to detect a wide range of medical events are disclosed. In some embodiments, the methods and systems do not require domain-specific knowledge or significant reconfiguration based on the medical event being analyzed, hence it is also possible to discover patterns previously unknown to experts. In some embodiments, to build precursor pattern detection models, the system obtains annotated monitoring data. Positive and negative segments are extracted from the annotated monitoring data, and are preprocessed. Features are extracted from the preprocessed segments, and selected features are chosen from the extracted features. The selected features are classified to create the precursor pattern detection model The precursor pattern detection model may then be used in real time to detect occurrences of the medical event of interest.

  • Patent number: 10265031
    Abstract: Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of alerting a user associated with an infusion device delivering fluid to the body of the user involves obtaining a first value for a physiological condition being influenced by the fluid, determining a metric corresponding to a future physiological condition of the user based at least in part on the first value, and automatically generating a first alert based on the metric. After automatically generating the first alert, the method continues by obtaining a second value for the physiological condition of the user and automatically clearing the first alert based at least in part on the second value.
