  • Patent number: 10692604
    Abstract: The invention relates to a system for determining the risk of cardiac arrhythmia in an individual. This system comprises the measurement of physical parameters (VA, VB, VC, D1, Vequ) of the individual and comparing the measured physical parameters (VA, VB, VC, D1, Vequ) with physical reference parameters (VAref, VBref, D1ref, VequRef). A statistical correspondence between the cardinal parameters (C1-C6) and a level of risk of arrhythmia is selected. The risk of arrhythmia in the individual is determined from the statistical correspondence and a previously selected number of cardinal parameters corresponding to extra-cardiac parameters.

  • Patent number: 10537257
    Abstract: While there are various methods for acquiring biological information based on pulse waveforms, none of the methods have been implemented in a biological information reading device that can be constantly operated stably. Provided is a biological information reading device which has achieved high accuracy by removing disturbance components from a pulse signal acquired by means of a multi-axis pressure sensor or a plurality of single-axis pressure sensors, and which can be attached to an examinee at all times for continuous observation taking advantage of the small and light-weight feature of the pressure sensors.

  • Patent number: 10531838
    Abstract: Chronic obstructive pulmonary disease (COPD) is one of the growing chronic respiratory diseases and is now a major cause of morbidity and mortality. Acute exacerbations have a negative impact on health related quality of life of COPD patients, survival rates, pulmonary function and utilization of health-care resources. The present application discloses an apparatus (100), system (1400), method (200), and computer program for assessing a risk of an exacerbation and/or hospitalization of a subject. To this extent, time-dependent activity data is Fourier-transformed to frequency space to obtain frequency-dependent activity data. Next, a moment of said frequency-dependent activity data is computed. Finally, a risk of said exacerbation and/or hospitalization of said subject to occur is assessed based on said moment.

  • Patent number: 10527507
    Abstract: An elastic strain sensor can be incorporated into an artificial skin that can sense flexing by the underlying support structure of the skin to detect and track motion of the support structure. The unidirectional elastic strain sensor can be formed by filling two or more channels in an elastic substrate material with a conductive liquid. At the ends of the channels, a loop port connects the channels to form a serpentine channel. The channels extend along the direction of strain and the loop portions have sufficiently large cross-sectional area in the direction transverse to the direction of strain that the sensor is unidirectional. The resistance is measured at the ends of the serpentine channel and can be used to determine the strain on the sensor. Additional channels can be added to increase the sensitivity of the sensor. The sensors can be stacked on top of each other to increase the sensitivity of the sensor.

  • Patent number: 10506966
    Abstract: Methods and systems relate to determining sensory motor performance based on user non-postural movements within a generated dynamic virtual environment. The generated environment requires users to: (i) utilize primary sensor inputs (e.g., vision, vestibular sensation and somatosensation); (ii) assess the dynamic virtual environment; and (iii) integrate and translate those inputs into movement to control the dynamic virtual environment. The methods may include receiving non-postural user input with respect to a state of one or more attributes of a dynamic virtual environment provided on a user interface for one or more sessions, the one or more attributes including a control object and a target which moves with respect to the control object; determining performance information based on the user input and the state of the one or more attributes for the one or more sessions; and determining sensory motor performance information from the performance information.

  • Patent number: 10492734
    Abstract: A patient visualization system having a processor may be communicatively coupled to a pressure sensor device to periodically receive pressure sensor data. The processor may determine a body position according to the pressure sensor data, and associate sensor data to body areas of the subject according to the body position. The associated sensor data may include sensor data indicative of an absence of pressure sensor data associated with one or more of the number of body areas. The processor may track pressure experienced by the body areas of the subject over a period of time to determine a pressure to the body areas over the period of time.

  • Patent number: 10485471
    Abstract: A system and method for identifying ictal states in a patient, the system including a plurality of sensors for sensing different non-electroencephalographic signals from the patient, and a processing unit. The processing unit has a processor and memory with instructions for classifying data from the plurality of sensors to determine probability of the patient being ictal, when the probability is high asking the patient if the patient is in an ictal state, reporting to a caregivers if the patient is ictal, and updating the classifier based upon sensor data, probability, and the response. The method includes sensing, using a plurality of non-electroencephalographic sensors, determining, using a classifier trained using a training dataset, probability of the patient being in an ictal state, and if probability is high, asking the patient if the patient is in ictal state, logging the occurrence of an ictal state, and updating the classifier.
