    Abstract: Techniques for suppressing noise in an environment of a magnetic resonance (MR) imaging system having at least one primary coil and at least one auxiliary sensor. The techniques involve estimating a transform, that, when applied to noise received by the at least one auxiliary sensor, provides an estimate of noise received by the at least one primary coil. The transform is estimated from data obtained by the at least one primary coil and the least one auxiliary sensor, with the data being weighted prior to estimation to remove or suppress data in regions with a high signal to noise ratio. In turn, the estimated transform may be applied to noise measured by the at least one auxiliary sensor during imaging of a patient, to estimate and suppress noise present in the MR signals received by the at least one primary coil during imaging.

  • Publication number: 20210153770
    Abstract: A method of operating a positioning system by registering a first coordinate system of a first positioning system in a second coordinate system of a second positioning system includes determining an interpolation function configured to register the first, non-orthonormal coordinate system in the second, orthonormal coordinate system. Fiducial pairs are collected by the respective positioning systems, each of which contain a respective coordinate in the respective coordinate system, both of which refer to the same physical point in three dimensional space. Establishing a working interpolation function involves an analysis of the fiducial pairs using a thin-plate spline algorithm. The method further includes repeatedly obtaining a first coordinate in the first coordinate system and determining a corresponding second coordinate in the second coordinate system in accordance with the interpolation function.

  • Publication number: 20210153773
    Abstract: Cough is a common experience and the most frequent reason why an individual seeks a visit to a physician. The prevalence of cough is about 10+% of the population. Cough is a manifestation of many aerodigestive tract disorders and especially consequential for serious lower airway diseases such as respiratory infections, chronic obstructive pulmonary disease (COPD) and asthma because increased coughing leads to emergency room visits and hospitalization. There is a need for methods to oversee coughing frequency in certain patients. Traditionally, all automated cough monitors have used cough sound as the signal for the measurement of cough. In the present invention movements of the diaphragm muscle, recorded by a motion sensor placed above the xiphoid process, are used for counting coughs. A device for such recordings is described and data were collected.

Reaction times between each of the first and second plurality of signals and the respective indication are determined. An observed curve is generated based on the reaction times. A differential curve is determined from the observed curve and a predicted curve. An area under at least a portion of the differential curve is determined. When the area is above a predetermined threshold, an indication that the user has satisfactory integrated sensory information is provided.

  • Publication number: 20210153806
    Abstract: Exemplary embodiments described in this disclosure are generally directed to systems and methods for detecting alertness of a driver of a vehicle. In one exemplary method, a driver alertness detection system determines whether a driver of a vehicle is susceptible to lagophthalmos. If the driver is susceptible to lagophthalmos, the driver alertness detection system may evaluate an alertness state of the driver by disregarding an eyelid status of the driver and monitoring biometrics of the driver such as, a heart rate and/or a breathing pattern. Alternatively, the driver alertness detection system may evaluate an alertness state of the driver by placing a higher priority on the biometrics of the driver than on the eyelid status. However, if the driver is not susceptible to lagophthalmos, the driver alertness detection system evaluates the alertness state by placing a higher priority on the eyelid status than on the biometrics of the driver.
