  • Patent number: 9782098
    Abstract: The present invention is related to a cardiovascular monitoring device including an inflatable cuff for surrounding a limb of a user, at least a first and a second electrodes, a controlling circuitry with a processor accommodated in a housing, and a display element. The controlling circuitry is configured to perform a blood pressure measurement through controlling a pressure inside the inflatable cuff, and perform an electrocardiogram measurement by using the electrodes. The processor is also configured to provide a diastolic blood pressure and a systolic blood pressure when the blood pressure measurement is performed, and to provide a heart rhythm information when the electrocardiogram measurement is performed. Further, for achieving a better and more stable contact between the electrodes and the user's skin, the present invention provides an improved structure with electrodes arranged thereon based on the conventional blood pressure monitor.

  • Patent number: 9770584
    Abstract: Systems and methods for treating atrial tachyarrhythmias such as atrial fibrillation (AF) are disclosed. By monitoring a patient's hemodynamic sensor response to a candidate AF therapy, the present systems and methods can be used to determine an individualized AF therapy leading to a desirable hemodynamic outcome. A medical system can include one or more programmable therapy circuits and a hemodynamic sensor circuit. The system includes a therapy selection circuit that automatically programs and sequentially delivers at least a first candidate therapy and a different second candidate therapy. By comparing the values of a hemodynamic parameter in response to or during the first candidate therapy to that in response to or during the second candidate therapy, a desired AF therapy can be determined as the candidate therapy that leads to faster or more significant hemodynamic recovery.

  • Patent number: 9700728
    Abstract: A system and method select a pacing site for a cardiac pacing therapy. A change from a baseline mechanical activity is extracted from a signal of mechanical heart activity during pacing at each one of multiple pacing sites along a heart chamber. A change from a baseline electrical activity is extracted from a signal of electrical heart activity during pacing at each of the of pacing sites. The pacing sites are sorted in a first order based upon the changes in mechanical heart activity and in a second order based upon the changes in electrical heart activity. A pacing site is selected from the multiple pacing sites as a common pacing site between the first order and the second order.

  • Patent number: 9665873
    Abstract: The invention relates to a system and method for analyzing an activity session. Data from a monitoring device worn by a user of the system for example is received over a period of time or distance and a classification system of the invention is utilized in real time or post session to determine the activities performed by the user during the session. The data collected relates to multiple parameters monitored during the activity session. The classification system defines an activity using a set of threshold criteria for a combination of parameters and therefore identifies a particular activity performed during the activity session when a combination of monitored parameters satisfies the threshold criteria for a particular activity. Determining the activities performed in this way allows for more useful interpretation of the data which in turn leads to more effective coaching advice and feedback for the user.

  • Patent number: 9629566
    Abstract: The present specification discloses systems and methods of patient monitoring in which multiple sensors are used to detect physiological parameters and the data from those sensors are correlated to determine if an alarm should, or should not, be issued, thereby resulting in more precise alarms and fewer false alarms. Electrocardiogram readings can be combined with invasive blood pressure, non-invasive blood pressure, and/or pulse oximetry measurements to provide a more accurate picture of pulse activity and patient respiration. In addition, the monitoring system can also use an accelerometer or heart valve auscultation to further improve accuracy.

  • Patent number: 9507042
    Abstract: An inversion-based algorithm for computing the time frequency analysis of reflection seismograms using constrained least-squares spectral analysis is formulated and applied to modeled seismic waveforms and real seismic data. The Fourier series coefficients are computed as a function of time directly by inverting a basis of truncated sinusoidal kernels for a moving time window. Spectra may be provided that have reduced window smearing for a given window length relative to the discrete Fourier transform irrespective of window shape, and a time-frequency analysis with a combination of time and frequency resolution that is superior to the short time Fourier transform and the continuous wavelet transform. The reduction in spectral smoothing enables enhanced determination of spectral characteristics of interfering reflections within a short window. The degree of resolution improvement relative to the short time Fourier transform increases as window length decreases.
