An apparatus for imaging one or more selected fluorescence indications from a microfluidic device. At the receiving-end device, a transmission rate modification section detects the transmission band of an optical transmission line based on the amplitude of the pilot signal, and decides a data transmission rate acceptable to the receiving-end device by taking into account the transmission band of the optical transmission line. The invention also relates to a process for using a catheter to pertubate the fallopian tubes to reduce dysmenorrhoea and premenstrual syndrome symptoms in a woman with the pharmaceutical composition that is intended to reach and exert an effect in the peritoneal cavity. The canceler, after canceling the multipath noise, outputs a purified version of the direct path signal nearly devoid of multipath noise. In one embodiment, a method of the invention includes treating a subject with an invention compound. The moulding can be extruded or can be molded.
