The present invention is directed to a pressure balanced fluid control device. In one embodiment, a method may include acquiring a plurality of dark images via a digital detector of an X-ray system. A plurality of spiked projections carried by at least one of the first and second retaining sidewalls, wherein a point of each spike is directed back towards the stabilizer arm. Such non-linear channels are more power efficient at creating RF energy from DC energy. High nutritional content and long lifespan of the processed product can be maintained, while reducing the weight of the final product.
