An energy administration device serves for operating an absorption refrigerating device with different energy sources and includes an energy control unit for controlling and selecting an energy source. The object detection circuit has a summation block, a noise reference determination block, a noise reference storing block, and a differentiation block. The BCA is present between the clamping area and the lead-in area and in which information regarding the optical disc is recorded, and the information is read before performing tracking in the data area. This step scales up a numerator for a ratio. On at least some of the surfaces of the three-dimensional object, the retrieved detailed information is provided. The apparatus may be in the form of a cabinet having a plurality of doors, each door having a secured position preventing access to the items within the cabinet.
