Voltage regulating systems are provided that adjust their output control signals in response to feed-forward information that is indicative of deterministic changes in the load current. A broadcast communication system transmits the broadcast media from a server to a communication terminal. The side panels have holes located thereon and are erected on the supporting surface. The first tween is employed to map the first time signal into a second time signal. The diode includes a first terminal connected to the isolation layer and a second terminal coupled to an isolation voltage source. An oral hygiene method includes brushing teeth with a dentifrice to which the oral composition has been added, and gargling with a mouth wash which includes at least one extract of crude drug selected from the group consisting of glycyrrhizae radix, arecae semen, myristicae semen and leonuri herba.
