In a multilayer piezoelectric element comprising a plurality of piezoelectric layers and a plurality of metal layers which are alternately stacked one upon another, the metal layers includes a plurality of high resistance metal layers having a higher electrical resistance than adjacent metal layers on the both sides. From the first process to the second process, DRAM cell capacitor layout area is reduced by the square of the scale factor, while cell capacitance is reduced by the scale factor. The peripheral wall has a front wall portion that projects upwardly to define a forwardly facing surface and is contiguous with a top wall portion that defines an upwardly facing surface having a substantial area to protect a wearer’s head. The system includes a data processor configured to receive information representing images of the storage locations generated by the image sensing device, and determine an inventory condition of the objects stored in the respective storage drawer according to the at least one first image.
