Gun scope and action cover comprises a water-proof, breathableair-permeable, reversible, light-weight, highly-flexible fabric pouch formed by an enclosed, cinchable elastic cord that fits over the optical scope of a rifle or hand gun, and that is universal in size, quiet in use, easy to put on and take off, and easy to store. The system includes a parametric configurator, a parametric configuration language, and a parametric data management system. At least one mounting member is movable between a first position in which a grid mounting section of the at least one mounting member is positioned in the housing and a second position in which the grid mounting section extends beyond a top surface of the housing to provide a mechanical connection between the grid and the connector. For each of at least two particular sub-sections, the method then computes a statistical parameter regarding the image values of the particular sub-section. One exemplary embodiment forms a feature into a substrate having a first substrate surface and a second substrate surface, and moves a sand drill nozzle along the substrate to remove substrate material sufficient to form, in combination with said forming, a slot through the substrate. Therefore, there is provided a technique for reducing the leakage current of MOS transistors in SRAM memory cells MC by controlling a potential of a source line ssl of the driver MOS transistors in the memory cells.
