  • Patent number: 11602282
    Abstract: A non-invasive method and system is provided for determining an internal component of respiratory effort of a subject in a respiratory study. Both a thoracic signal (T) and an abdomen signal (A) are obtained, which are indicators of a thoracic component and an abdominal component of the respiratory effort, respectively. A first parameter of a respiratory model is determined from the obtained thoracic signal (T) and the abdomen signal (A). The first parameter is an estimated parameter of the respiratory model that is not directly measured during the study. The internal component of the respiratory effort is determined based at least on the determined first parameter of the respiratory model. The first model parameter is determined based on the thorax signal (T) and the obtained abdomen signal (A) without an invasive measurement.

  • Patent number: 11589814
    Abstract: The disclosure describes a wearable, low-cost and low-power Electrical Impedance Tomography system for gesture recognition. The system measures cross-sectional bio-impedance using electrodes on wearers' skin. Using all-pairs measurements, the interior impedance distribution is recovered, which is then fed to a hand gesture classifier. This system also solves the problem of poor accuracy of gesture recognition often observed with other gesture recognition approaches.

  • Patent number: 11224350
    Abstract: A method for detecting an artifact of a blood pressure signal includes measuring consecutive signals of blood pressure in real time, dividing the consecutive signals into a plurality of unit waveforms by searching systolic starting points and peak points from the measured signals, determining two outputs by applying N consecutive unit waveforms among the plurality of unit waveforms as an input to a deep belief network (DBN), and determining whether the signal is an artifact or a normal signal by using the two determined outputs. According to the present disclosure, it is possible to minimize various false alarms of bio-signal streams which are measured in real time by automatically eliminating ABP artifacts using a deep belief network (DBN) which is one of deep neural network (DNN) models capable of learning causes and shapes of various types of artifacts together.

    Abstract: A monitoring method is performed by a digital processor while a subject is asleep or with little movement. The method includes receiving transducer signals for a subject and training a model for characteristics of a subject or subject group. The model is used in generating sleep data according to real-time correspondence and values of transducer signals including subject rib displacement, subject abdomen displacement, subject torso movement, and subject orientation. Combinations of the transducer inputs are used to determine features from which outputs such as an AHI score are determined. A feature matrix is normalized based on dynamically-generated positional epochs bordered by subject movements to new positions and used to provide a normalization matrix.
