The present invention relates to a capacitance reducing method for a pulsed activated device and associated devices, especially to a pulsed activated device having a capacitor, which improves power factor as well as eliminating the need for large capacitance. The products may be snack chips, cakes, crackers or the like, made from food starch material. Each cover assembly includes a first cover piece pivotally coupled to an end wall of the spa base, two bracket assemblies pivotally coupled to the end wall and the first cover piece, and a second cover piece pivotally coupled to the first cover piece.
