The invention provides a method and apparatus for a web-related state machine. Such disclosed example methods also include quantizing a second set of transform coefficients based on a second scale factor corresponding to the first scale factor reduced by a unit of resolution to determine a second set of mantissas, the second set of transform coefficients corresponding to the first band of the compression standard and including the watermark. Alternatively, the mating formation pair is defined by an opening of the receptacle and a conductor of the plug, each having a cross-sectional height that is reduced from that of a standard receptacle and plug. The moving object is then classified as one of a set of possible classes according to the extracted features, and an alarm signal can be generated indicating the selected class. The frame includes at least one elastic element urging the light guide plate, thus keeping the incident surface in contact with the light source. The controller in particular comprises communication means for communicating directly with one or more neighboring controllers for the external cellular network or network segment, for sharing of the registered information about cells and their relationships.
