  • Patent number: 10874321
    Abstract: A phase singularity identification system includes: a signal reception unit for receiving a single activity electrogram signal measured through a single-electrode catheter at a particular point of a cardiac muscle cell; a phase calculation unit for calculating a phase from the received single activity electrogram signal; and a phase singularity identification unit for identifying through the calculated phase if the particular point of the cardiac muscle cell is a phase singularity. Accordingly, it is possible to identify the phase singularity of a rotor by using a single-electrode catheter rather than a multi-electrode catheter, thereby significantly reducing time required and costs spent in comparison with prior art, and it is possible to accurately identify the phase singularity of the rotor, thus the system can be used for a radiofrequency electrode catheter ablation procedure for cardiac arrhythmia treatment.

The tracking errors may be used to generate numerical values for model parameters that correlate the subject's responses to the tracking errors during the course of the dynamic motor tracking task. A classification model may be used to compare the model values to multi-subject model values of known diagnoses for mTBI. The entire screening process can be effectively administered in a matter of minutes or less, and with a high degree of accuracy.

  • Patent number: 10874358
    Abstract: A method for detecting the need for providing assistance to an individual suspected of overdosing on an opiate is provided. The method includes using a wearable device for continuous or intermittent monitoring of one or more physiological parameters of the individual. If the level of one of the one or more physiological parameters exceeds a threshold level specific to that parameter, an alarm is triggered. If the alarm is not aborted, an alert is transmitted to one or more emergency contacts conveying that the individual has overdosed. The method optionally provides for injection of an opioid receptor antagonist into the individual to reverse the effects of the overdose. Also provided is a device for implementing these methods.

  • Patent number: 10874360
    Abstract: A dose setting unit generates dose control data in order to change a unit time dose of an X-ray beam with which a subject is irradiated during X-ray tomography. An imaging controller makes X-ray intensity when a center axis X-ray (irradiation axis) of an X-ray beam emitted from an X-ray generator is not orthogonal to a tomographic layer of interest relatively smaller than X-ray intensity when the center axis X-ray is orthogonal to the tomographic layer of interest.

  • Patent number: 10874364
    Abstract: An apparatus and method for three-dimensional inspection of an object by X-rays. The apparatus includes an X-ray generator and a digital imaging device spaced from each other by a distance which defines a magnification by 1 on the imaging device. The apparatus also includes a means for moving the X-ray generator and identically the imaging device by unitary movements in two orthogonal directions. Each unitary movement corresponds to an integer number fraction of the side of the imaging device, and obtains, by successive shots after each unitary movement, a matrix set of sub-images overlapping in the plane of extension of the imaging device. Each sub-image has a center with coordinates in a plane of magnification equal to N. An image processing means performs magnification of each sub-image and determines a stretch factor enabling the coincidence of the sub-images representing all or part of a predefined element of interest.
