According to one embodiment, an integrated circuit device includes a plurality of interconnects and a contact via. The voltage regulation system includes: an input power source: a series resistor connected in series to the input power source; and an MIT insulator connected in series to the series resistor, and undergoing an abrupt MIT such that the range of an output voltage regulated to be kept constant varies according to the resistance of the series resistor. The system stores the time of the scan and links the item identification number scanned to the inventory control system. The method includes using the machine to read the product barcode on each of the products loaded into the machine. There are means for coordinating energy absorbing units 24 in one of the one or more modules, the means for coordinating 24 having a topography including a number of apertures 26 defined therein, where n is an integer \u22670.
