    Abstract: A method of analyzing electrocardiograph (ECG) data includes receiving a first representative ECG of a patient and isolating a first principal component, a second principal component, and a third principal component of the first representative ECG. The principal components are isolated by selecting a portion of the first representative ECG relating to depolarization, calculating a covariance matrix based on the portion of the first representative ECG, conducting a principal component analysis of the covariance matrix, and selecting a first component of the principal component analysis as the first principal component, the second component of the principal component analysis as the second principal component, and the third component of the principal component analysis as the third principal component. A depolarization subspace is then formed based on the first principal component, second principal component, and the third principal component of the first representative ECG.

The expansion of the gasket provides additional compression of the gasket and closes gaps that might otherwise form due to expansion of the oven door as the oven heats. The gasket can be effective even at high temperature oven operation such as e.g., during a cleaning cycle.

  • Patent number: 9377029
    Abstract: A blade of a turbomachine or a flying machine includes a blade airfoil extending in a radial direction from a blade root to a blade tip. The blade airfoil has an inflow-side leading edge, an outflow-side trailing edge, a pressure side and a suction side. A surface of each of the pressure side and the suction side extends between the inflow-side leading edge and the outflow-side trailing edge. The blade tip has an end face with a camber line that extends from the inflow-side leading edge to the outflow-side trailing edge. At least one tip-side recess forms a depression from the end face into the blade airfoil, the depression extending continuously from the pressure side to the suction side and having a partial length of the camber line.

  • Patent number: 9377199
    Abstract: Various embodiments include methods of reinforcing apertures in turbomachine combustors, and related combustors. In various particular embodiments, a method of reinforcing an existing turbomachine combustor aperture includes: broaching the existing aperture to modify an initial profile of the existing aperture and form a modified profile, where the modified profile protrudes radially outwardly from an outer surface of the turbomachine combustor; and welding a combustor ring along an inner surface of the modified profile, where the modified profile enhances bonding between the existing aperture and the combustor ring.

  • Patent number: 9377221
    Abstract: A heat pump system is provided that uses multiple stages of MCMs with different Curie temperature ranges. An adjustable fluid flow path is used whereby the number of stages through which a heat transfer fluid passes can be varied depending upon e.g., the amount of heating or cooling desired. In certain embodiments, a magnetic field used to activate the MCMs can be manipulated so that the number of stages of MCMs that are activated also be adjusted. These and other features can improve the operating efficiency of the heat pump.
