  • Patent number: 10537279
    Abstract: A method of operating a CPAP apparatus in which the interface pressure is controlled to rapidly drop at the start of expiration by an expiratory relief pressure (ERP) that is independent of instantaneous respiratory flow, following which the pressure rises to an inspiratory level at or shortly before the end of expiration, or at the onset of an expiratory pause, if any. The ERP is an increasing function of the inspiratory pressure. The expiratory pressure follows a template that is a function of the expected expiration time, the magnitude of the template being equal to the ERP. The current estimated proportion of expiration is determined by comparing the expiration time of the breath in progress to low-pass filtered expiratory durations measured for a number of the preceding breaths.

  • Patent number: 10478612
    Abstract: Various systems and methods for non-invasively monitoring and treating a medical condition of interest via transcutaneous stimulation of a target nerve are described. For instance, a subject can be monitored for improvement of a medical condition, where such improvement corresponds with a decrease in the threshold level at which a sensory or motor response is elicited in a subject upon stimulation as compared to a baseline level. Further, transcutaneous stimulation of the nerve can also treat the condition. Both monitoring and treatment can be carried out in a non-invasive manner substantially free of a painful response via electrical nerve stimulation of a target nerve, where the stimulation is delivered from an electrode placed on a non-glabrous skin surface. The electrode placement sufficiently immobilizes the target nerve such that the stimulation is effective and can be delivered in a controlled manner.

In accordance therewith, a spatial element associated with a region of the heart is selected. Progressive rotational activations or progressive focal activations are determined in relation to the selected spatial element over a period of time. The selecting and determining are repeated over multiple periods of time. A source parameter of rotation activations or focal activations is determined, wherein the source parameter indicates consistency of successive rotational activations or focal activations in relation to a portion of the region of the heart. The determining of a source parameter is repeated for multiple regions of the heart. Thereafter, representation of the source parameter is displayed for each of the multiple regions of the heart to identify a shape representing the source of the heart rhythm disorder.

  • Patent number: 10433750
    Abstract: Disclosed are a method for generating an electrocardiogram for personal identification and a method for identifying a person using the electrocardiogram. The electrocardiogram generation method generates a normalized electrocardiogram by extracting single-cycle electrocardiogram signals meaningful for personal identification from an electrocardiogram of a person and by connecting the extracted single-cycle electrocardiogram signals arranged in temporal order. Therefore, the electrocardiogram generation method dramatically increases identification accuracy in personal identification.

    Abstract: A heart rate monitor system having at least one primary heart rate sensor (110) for measuring or determining a heart rate of a user and for outputting an output signal (HR) is provided. The output signal (HR) is based at least on measured heart beats and/or artifacts. The heart rate monitor system also comprises a model unit (132) for estimating or predicting a heart rate (HRM) of a user based on a model stored in the model unit (132) and the information received from at least one secondary sensor (120) measuring at least one physiological factor influencing heart rate of a user. The heart rate monitor system furthermore comprises a processing unit (131) for correlating the output signal (HR) received from the primary sensor (110) with the estimated or predicted hear rate (HRM) received from the model unit (132) to differentiate the measured heart beats from the artifacts.

  • Patent number: 10390730
    Abstract: Disclosed are methods, systems, and devices for determining a respiration rate. An example method includes capturing by a wearable device over a non-zero time period a PPG signal and making a first determination that, during the non-zero time period, the wearable device has moved less than a threshold amount. Responsive to the first determination, the method includes (i) determining from the PPG signal each of (1) a respiratory-induced intensity variation (RIIV) signal, (2) a respiratory-induced amplitude variation (RIAV) signal, and (3) a respiratory-induced frequency variation (RIFV) signal; and (ii) making a second determination that, based on the RIIV signal, the RIAV signal, and the RIFV signal, a respiration rate is determinable. Responsive to the second determination, the method includes (i) determining the respiration rate and (ii) providing by the wearable device a notification, with the notification being based at least in part on the determined respiration rate.

  • Patent number: 10362951
    Abstract: The present disclosure uses physiological data, ECG signals as an example, to evaluate cardiac structure and function in mammals. Two approaches are presented, e.g., a model-based analysis and a space-time analysis. The first method uses a modified Matching Pursuit (MMP) algorithm to find a noiseless model of the ECG data that is sparse and does not assume periodicity of the signal. After the model is derived, various metrics and subspaces are extracted to image and characterize cardiovascular tissues using complex-sub-harmonic-frequencies (CSF) quasi-periodic and other mathematical methods. In the second method, space-time domain is divided into a number of regions, the density of the ECG signal is computed in each region and inputted into a learning algorithm to image and characterize the tissues.
