A charitable donation system that facilitates and monitors charitable donation based on payment card loyalty contributions is disclosed. The invention encompasses a method for injecting a fluid wherein a transfer body is freely accelerated for a distance and strikes a contact point thus generating an initial impulse or pressure to expel the fluid. A controlled secondary rectifier unit includes a plurality of rectifier switching units to reduce reactive power in the primary converter unit. Multiple rows are provided to allow for the definition and selection of overlapping regions of interest. The controller controls relay apparatuses and adjusts a flow of current to control units, in addition to controlling its own CPU clock frequency.
