Provided are an LMA, a proxy router, and a management method for supporting NEMO in a PMIPv6 network. The adjustable meter loop assembly includes a first pipe, a second pipe, and a meter bar assembly connecting the first and second pipes. For example, an embedded mail object may include a newsletter, a survey, a quiz, or a promotion. A locking member disposed at a side of the closed loop provides interrelated adjustment of the open and closed loops to tighten the closed loop around the seatback. This arrangement allows the semiconductor storage device to read data with accuracy at high speed and allows the semiconductor storage device to be miniaturized at low cost.
