专利汇可以提供Environmental control apparatus专利检索，专利查询，专利分析的服务。并且The apparatus re-creates indoors electric and magnetic fields which occur naturally out-of-doors. A direct current field is created in an enclosure, such as a building, and low-frequency recurring disturbances or pulses are created in the field. The disturbances and/or the direct current field can be varied in time duration and frequency, either in a random manner or a predetermined pattern, in order to avoid unresponsiveness of the persons in the building to the beneficial effects of the fields.，下面是Environmental control apparatus专利的具体信息内容。
