    Abstract: A new combination of existing technologies that turns an Alternator, in order to generate electricity, where the Alternator of the present day is designed with the same design principles as the 1896 Tesla Generator. In addition, due to a new combination of existing technologies, electricity is generated utilizing the Tesla Generator, without pollution causing gasoline or diesel engines, nor connection to the electric grid, and, without the need for wind-power nor hydro-power. Thus, electricity is generated when needed, anytime, anywhere, without the need for an internal combustion engine, nor forces of nature such as wind & water.

  • LOW-FIELD MAGNETIC RESONANCE FINGERPRINTING
    Publication number: 20200103481
    Abstract: A magnetic resonance fingerprinting (MRF) method for determining parameter values in pixels of an examination object can use a magnetic resonance system with, for example, a constant magnetic field strength (e.g. of less than 1.5 tesla or a constant magnetic field strength of less than 0.5 tesla). The MRF method can be adapted for conditions that prevail with such low-field magnetic resonance systems, thus enabling the parameter values to be advantageously determined efficiently while simultaneously maintaining a high degree of quality.
