An automatic paper ejecting and stacking machine for use with vertically-loaded desktop hole-punching equipment is disclosed. The user selects outputs to be activated for each of the sequential steps and any inputs to be monitored or timer to be enabled for the sequential steps. The power generation unit is configured to provide current and power to the utility system as a function of the power and current that is measured by the grid measurement device. A difference of the first and the second voltage signals indicates a phase error of the quadrature four phase output signals. The method concludes by storing filtered 3D seismic attribute data within the filter half length in each 3D direction along with null values for all non-reliability locations outside the filter half length but within the focused subvolume of interest forming a 3D output volume. The slat is formed in a tubular configuration and has a base material of glass fibers bonded together in a thermoformable resin so as to maintain the arcuate curvature desired for the tubular slat or vane.
