The dentifrice is at least partially transparent with suspended hexagonal shaped pieces. A voltage produced by applying the reference current to the adjustable on-chip impedance is sensed and compared with the comparator or other similar processor to a reference voltage. The method may be implemented on a computer based system. Each mounting adapter has a second interface for fastening it to at least one of the varied cleaning blade mounts in the same way that a conventional cleaning blade is fastened. During each cycle, if a bit pattern cannot be identified as a data bit, then the size of the examined bit area is increased and rechecked to see it specifically is a marker bit. All modules of a port undergoing link state training placed into an intermediate state prior to entry into the lowest power state.
