The present invention is related to digital to analog converter input data encryption off-chip and decryption on-chip to suppress input data in-band harmonic leakage through package related parasitic capacitance. The analyzer can include multiple lanes each having a filter to receive and filter debug data, a compressor to compress the debug data passed by the filter, a buffer, and a controller to store the compressed debug data into the buffer, where the compressed debug data can be stored without timing information. In the foreign matter anti-adhesive means 180, a shaft 181 which is rotatably supported by two columnar supports 184 fixed onto a base 186 is coupled to a motor 182 by a coupling 183. Several variations of this technology may be adapted for use with hot, cold or ambient temperature beverage preparation methods. One or more retardation films and a compensation layer can compensate for color, with the compensation layer also improving the viewing angle.
