An energy consumption simulation and evaluation system for embedded device in energy consumption evaluation technology for electronic devices, which solves the problem that the energy consumption cannot be simulated under tasks operation condition with the existing systems. The manual and automated systems and methods operate to dispense DCM powder, as well as liquid, into vessels or media preparation instruments in a manner to avoid DCM dust inhalation by persons in the surrounding area and contamination of equipment and surfaces in the surrounding area. The injection well includes an injection well reservoir opening in fluid communication with the reservoir. The spatial frequency information that is displayed by the plurality of information display unit is projected by using diffraction light, and a plurality of video images are synthesized on projection surfaces. On the basis of the current intensity determined, a distinction is made as to the material of which the object surface is formed.
