An apparatus for processing nuts and fruits, and more specifically, to a mobile apparatus that picks-up fruits and nuts, and similar products from the ground and conditions them, in bulk. Each unit has a shape adapted to a saw-cut recess accommodating the unit. Using an electronic toner area cover sensor system, the amount of smearing can be determined, From this, the timing of engagement of the transfer assist blade with the photoreceptor can be determined and, if necessary, adjusted. The distance between lead attachment points is adjusted with the interval adjustment structures to finely adjust the voltage induced at the voltage detection terminals due to current flow between the two attachment points. The sidewalls have a bottom portion comprised of a thermoplastic material for contacting the ice surface. This invention also provides a method of combining the output of individual, combined attribute energy storage systems to provide user definable and expandable electrical energy production.
