There is provided an AC motor controller capable of detecting an abnormal state of a motor cable while an AC motor is operating without using a special circuit but using a processor. In another aspect, disclosed is a method for evaluating a pharmacological effect of a treatment with B-lymphocyte inhibiting or depleting therapy. The access authorization data remain added to the sound andor picture contents, even in cases of a cascading, encoded retransmission, or remains logically linked thereto by suitable means, even if transmitted physically separate along with the picture andor sound contents. The hardware formatting logic of the present invention can perform bit shifting, resolution reduction, bit per pixel reduction, data masking for shingling, and input data sourcing. The dilator may be slideably displaceable relative to the sheath. Also disclosed are contact lens disinfecting systems which are designed to maintain a high concentration of hydrogen peroxide solution for a longer period of time before increasing the overall surface area of catalyst exposed to the hydrogen peroxide solution.
