The present invention provides an anti-adhesion transparent thin film, which uses physical vapor deposition to deposit a transparent thin film on the surface of a substrate. The system includes the policy determination combination device and multiple bearer and transmission devices. Fatalities due to wrong blood type transfusion have increased yearly. In another form the content in the one ear may be a time shifted version of the other ear content. The switching power supply includes a freewheeling MOSFET 6 serving as the freewheeling switch element which operates synchronously with the switching element 2 and a surge voltage prevention circuit 32. An end user is alerted to the termination of the illumination of the plurality of lighting fixtures before termination occurs.
