An object within a region is exposed to a first beam of penetrating radiation. The power sliding assembly includes a motor fixedly secured to the window frame. 5 to 5 nm, and a light-emitting device including said phosphor and a light source for excitation light with an intensity of 3 to 800 Wcm2. The changes in the deoxy-Hb andor the oxy-Hb may then be compared to determine a state of anesthesia. A wide bandwidth steerable flat panel array utilizing the dipole fed slot antennas may be mounted on the deck house or other flat structural component of a vessel so as to perform a smart skin function in which the antenna not only functions as a radiating element, but also as a structural part of the vessel itself.
