In an operation control apparatus of a compressor, a current, a voltage an d a TDC, etc. A capability is determined to communicate over a radio interface using multiple radio frequency component carriers. The image capturing unit and the object illumination unit are connectedly moveable relative to the object placement unit so that in all positions of the image capturing unit and the illumination unit, the object can be placed on the object placement unit so that the illumination unit can be provide the illumination required for the image capturing unit to take silhouette images of the object. The singular part detecting circuit detects a singular part in each of the image data. An offset canceling section 26 calculates an average value of amplitude of a signal which should have an average of amplitude within a predetermined time range of 0, subtracts the average value from the signal and thereby removes an offset included in the signal. The invention also relates to pharmaceutical formulations of said compounds, methods of treatment using said compounds and to processes for the preparation of said compounds.
