A dioptric power distribution measuring device measures the dioptric power distribution of a target lens. The absorbent pad additionally includes chitosan to better use the absorbing capacity of the absorbent layer. The split power supply may include at least a first voltage supply line and a second voltage supply line. Based on the harvest quality parameter, and preferably a yield grade, the specimen is categorized. The approach allows manipulation of the audio objects to be controlled by the decoder but performed fully or partly by the encoder.
