A device for extracting a synchronization signal from a video signal has a first comparator and an adjustment circuit. In one embodiment, the method correlates a person’s RFID tag with an RFID of an asset and uses this information to determine whether an asset is allowed to pass an access point. The reagent applying tool includes at least one reagent holding section which penetrates the reagent applying tool in a thickness direction and which holds a reagent by capillary action, and a reagent spreading section for spreading, on the surface of the gel, a reagent supplied from a lower-side opening of the reagent holding section when the reagent applying tool is placed on the gel. The third transducer is connected to the second output terminal and the terminal for applying the reference potential. A method of making a shape memory material also includes curing a thermoplastic polymer to prepare a cured thermoplastic material. Upon exiting the burner venturi, the airgas mixture is to a plenum and radiant surface where combustion takes place.
