A method for dynamically maintaining compatible contamination levels of equipment, wafer Lots and FOUP’s used for automated processing of a Split Lot of wafers. The system also has a sensor module for continually sensing at least one of electrical and physical properties proximate a surgical site and generating at least one signal and a control module for continually receiving the selected parameter from the user interface and the at least one signal from the sensor module. The collecting roller picks up and stores the hair, fibers and other debris that have been lifted by the static electric charged bar or roller and deposits them in a collection section of the device for disposal. The inner rotor includes an inner set of blades. The quantization index modulator and perception processor are coupled to a compensation processor which generates an output signal by modifying a strength of the distortions of the modified signal in response to the perceptual characteristic. In one embodiment, a carry-less multiplication instruction may be used to perform operations corresponding to verification of an encrypted message in accordance with GCM.
