The invention relates to a method and a machine for producing a seam which is not susceptible to coming undone, with at least one interlooped andor interlaced stitching thread and with stitching passes in or through at least one thickness of the material of an object, called the sewn object. The system is arranged such that the DRAMs that constitute a given rank are re-mapped across the available DIMMs plugged into the slots, such that a data word to be stored in a given rank is striped across the available DIMMs, thereby reducing the loading on a given byte lane that might otherwise be present. The two part cover includes a removable protection device used to protect the reticle from contaminants. The invention allows an easy manufacturing process without bubble formation, and eliminates entry and formation of bubbles due to external changes such as in temperature and pressure, thereby allowing good performance of the lens regardless of external environmental changes. The assembly is positioned adjacent the absorber and is either substantially within or adjacent to the bumper beam. The method comprises detecting a semi-persistent scheduling activationreconfiguration signaling over a physical downlink control channel only during an SPS activation window, wherein the SPS activation window precedes a discontinuous reception on-duration by a predetermined amount of time.
