Systems and methods for enabling arbitrary components to transfer current, contextual data between each other without requiring prior knowledge of each other. The apparatus includes a venturi valve to extract concentrated cleaningdisinfectant fluid from a storage container. An adaptive structure can be positioned in a path of the radiation beam and can have a plurality of independently controllable and selectively radiation transmissible elements, each configured to change at least one of the amplitude distribution, the phase distribution and the polarization distribution of the radiation beam. A surface on one side of the wiring board is a device forming surface including the plurality of the LED chip groups, an external connecting terminal for leading out electrodes, and a wiring pattern for electrical connection between the LED chip groups and the external connecting terminal. The load circuit includes a load detecting unit and a load.
