Disclosed is a method of running a viral advertisement service. However, at present most of such screening processes involve only metal detectors, which are inherently incapable of detecting non-metallic illicit objects and materials. Due to the dual plane balancing means the color wheel is better balanced. The metal electrodes are formed on the transparent ITO electrodes and in parallel to the transparent ITO electrodes. The protocol security functions and common security function utilize conventional and fuzzy logic rules to generate protocol security data and common security data. The method is performed by modeling selected ECG confounders that tend to obscure AMI evidence in the ECG waveform, and by purging a subject’s ECG waveform of the effect of these confounders through linking selected confounder models with an appropriate, computer-implementable purge algorithm.
