Abstract: The present disclosure is directed to a coupling assembly for a turbomachine. The coupling assembly includes a liner and a sleeve at least partially positioned circumferentially around the liner. A frame is positioned between the liner and the sleeve. The frame includes a first side wall, a second side wall, and a base wall extending from the first side wall to the second side wall. A block is positioned between the liner and the sleeve and is movable relative to the frame to permit the block to move toward and away from the base wall. Moving the block away from the base wall causes the block to exert an inward force on the liner and the base wall to exert an outward force on the sleeve.

Abstract: Risk determination for a near fatal ventricular arrhythmia of a patient. An electrocardiogram of a heart of the patient is obtained. A parameter is measured, using an electrocardiogram of a heart of the patient, indicative of an autonomic nervous system of the patient. A numeric score is assigned for the parameter indicative of the conduction system of the heart. A numeric score is assigned for the parameter indicative of the autonomic nervous system. A ratio of the numeric score of the parameter indicative of the conduction system of the heart of the patient and the numeric score of the parameter indicative of the autonomic nervous system of the patient is calculated. The risk of the potentially near fatal ventricular arrhythmia of the patient is determined to be significant if the ratio is greater than a predetermined threshold. An action responsive to the determining step is taken.
