A nonvolatile memory cell is provided. In an alternate embodiment, the invention contemplates a polarization insensitive optical circuit comprising a polarization rotator reflector, and a polarization sensitive operator which may comprise for example a first polarization rotator, an operatorcoupler, and a polarization beam combiner. The cartridge includes a holding chamber for holding a mixing solution and a dilution chamber. Accordingly, the system determines the cell location of the cellular telephone and establishes a communication of the subscribed data to the watch via the local cellular provider for the same cell location as that of the subscriber’s cellular telephone. The device includes elements that are structurally integrated into the door andor the flange and can form a separation between the communication space and the inner annular critical line andor the outer annular critical line, when the doors are open.
