Abstract: An integrated system for hydrogen purification, storage, and pressurization, including a first heat exchanger, a second heat exchanger, a third heat exchanger, a fourth heat exchanger, a hydrogen storage tank, an adjustable heat and cold source; a gas pump, a first circulation pump, a second circulation pump, a third circulation pump and a fourth circulation pump. The first heat exchanger is provided with a first low-pressure metal hydride reactor. The second heat exchanger is provided with a second low-pressure metal hydride reactor. The third heat exchanger is provided with a medium-pressure metal hydride reactor. The fourth heat exchanger is provided with a high-pressure metal hydride reactor. The first low-pressure metal hydride reactor is connected to the second low-pressure metal hydride reactor, and the medium-pressure metal hydride reactor is connected to the high-pressure metal hydride reactor. An integrated method for hydrogen purification, storage, and pressurization is also provided.

Abstract: A control method and a sense organ testing method based on steady state brain evoked response include the steps of: generating one or multiple stimulus signal(s) varying in various frequencies that can be sensed by sense organs of human subject; detecting the brain electrical signal of stimulated human subject; analyzing the detected brain electrical signal to extract the characteristic physical quantity corresponding to the frequency of a stimulus signal; and, according to the characteristic physical quantity, controlling a specific device corresponding to the stimulus signal to perform a preprogrammed operation or objectively evaluating the condition of the sense organ of the subject.
