A radio station optimizes the impedance. The apparatus is comprised of a pneumatic chest compression vest, a pneumatic pressure generator, and a mouthpiece connected to a nebulizer. According to a first predetermined manner, the signal transformation circuit transforms a set of image signals into a set of transformed signals. The second inner electrodes 41 to 44 are electrically connected to each other through the second connecting conductor 9. A second robot may be used to support testing of a sick robot. The optical probe receives light from the illumination system and transmits it to tissue, and receives light diffusely reflected in response to the broadband light, emitted from the in vivo tissue by fluorescence thereof in response to the broadband light, or a combination thereof.
