  • Patent number: 10368764
    Abstract: A system and method to select segments of cardiac signals. Each of a plurality of segments in a first signal is correlated at a plurality of offsets to determine a highest correlation coefficient for each of the plurality of segments in the first signal. Each of a plurality of segments in a second signal is correlated at the plurality of offsets to determine a highest correlation coefficient for each of the plurality of segments in the second signal. A plurality of composite correlation coefficients is generated using highest correlation coefficients for segments of the first signal and segments of the second signal. The segments of the first and second signals are approximately contemporaneous. A set of segments including a segment from the first signal and a segment from the second signal is selected. The set is associated with a highest composite correlation coefficient from the plurality of composite correlation coefficients.

  • Patent number: 10363173
    Abstract: Embodiments of this disclosure disclose an imaging system, including an eye interface device, a scanning assembly, a beam source, a free-floating mechanism, and a detection assembly. The beam source generates an electromagnetic radiation beam. The detection assembly generates a signal indicative of an intensity of a portion of the electromagnetic radiation beam reflected from the focal point location. A subsequent focal point of the electromagnetic radiation beam may be adjusted per the measured intensity signal. In some embodiments, an intensity signal below a lower threshold value may suggest a depth increase for a subsequent focal point. An intensity signal above an upper threshold value may suggest a depth decrease for a subsequent focal point. And, an intensity signal between the lower and upper thresholds may suggest a depth be maintained for a subsequent focal point. The focal point may be adjusted after each pulse or after a plurality of pulses.

  • Patent number: 10362997
    Abstract: A system (100) for monitoring and diagnosing heart conditions includes a sensor array (102) with accelerometers, an electrocardiogram sensor, and a system to synchronously capture and process (103, 105, or 106) composite heart signals. The system performs separation, identification and marking (201-205 or 501-509) of the signals, to extract information in cardiac vibrations. Machine learning, auditory scene analysis, or spare coding approaches can be used to resolve source separation problems. Analysis of the composite signals separates different vibration signals (302, 303, 304, 305), identifies streams for particular valve signal, and marks them with event time information with respect to a synchronous electrocardiogram signal (306). The psychoacoustic analysis mimics human auditory processing to enhance hearing of heart valve sounds by separating valve vibrations from the composite signal, and providing extraction, identification, marking and display of individual valve signals.

  • Patent number: 10357652
    Abstract: A method for implanting a neurostimulation lead within a patient includes measuring impedances of electrodes on the lead in order to correctly position the lead relative to a target tissue region. The electrodes are circumferentially segmented electrodes that are spaced from each other about the longitudinal axis of the lead. When the difference between the impedances of the electrodes exceeds a threshold value, the lead is in the correct position. In accordance with another embodiment, impedance measurements are used to select which one of the electrodes is closest to the target tissue region. By determining which electrode has the highest impedance and which electrode has the lowest impedance, the type of tissue adjacent to each electrode can be determined based on the conductivity properties of the tissue. The target tissue region may be a spinal cord, a posterior longitudinal ligament, white matter, or gray matter.

  • Patent number: 10300285
    Abstract: Electrical stimulation sources and amplitudes are allocated to implantable electrodes based on impedance values for controlled delivery of electrical stimulation therapy to a patient. Allocation may include assigning implantable electrodes, in a group of active electrodes, to clusters based on impedance values of the electrodes, coupling the electrode clusters to respective stimulation sources, and defining respective stimulation amplitudes delivered by the stimulation sources to the electrode clusters. Each cluster may include electrodes having relatively similar impedance values, such that electrodes in each cluster present less variation in impedance relative to impedance variation across the group of electrodes. With reduced variation in impedance, in some examples, variation in current outflow through electrodes in each cluster may be reduced, promoting more uniform distribution of stimulation current across the group of active electrodes and a more uniform stimulation field.
