Abstract: The invention relates to a method of measuring earth ground resistance. The method comprises the steps of: Performing an earth ground resistance measurement by means of an earth ground measurement device, thereby obtaining measurement data, Gathering the measurement data via at least two different channels of the earth ground measurement device such that multiple measurements are performed at once, wherein each channel is configured to perform an earth ground resistance measurement, and Uploading the measurement data automatically to a remote processing module separately formed with respect to the earth ground measurement device. Further, a system for measuring earth ground resistance is described.

Abstract: Disclosed is a real time diagnostic apparatus and method quantitatively evaluating, in a noninvasive manner, cerebral phenomena. Surface electroencephalographic (EEG) signals are obtained and filtered in a desired frequency range. Digital EEG data is normalized and the dynamic phase and density relations within the signal are characterized by processing the filtered signals to generate Kth-ordered spectral values where K is an integer greater than 2. A diagnostic index which quantifies the detected cerebral phenomena is then derived from the generated Kth-order spectral values.
