A resistive memory device includes a first electrode, a resistive oxidation structure and a second electrode. A user interface allows selection of the function of an attached optical imaging platform that is desired by a user. The stationary seat has two 7 inch wide spaces with 1\xbd inches of air space under the prostate. The loaded auxiliary holes of the auxiliary center-cut holes are blasted so as to create a circular pre-split. The system controller holds an input and output of at least one of either the focus controller or the tracking controller on the basis of the output of the defect detector, and sets an initial value in a delay memory of the digital filter of the controller held upon awake of the hold state. The housing pieces have a modular embodiment which may be stacked one over the other in an indexed manner, whereby the inlet opening of the upper housing piece forms the outlet opening of the housing piece below.
