Abstract: 휴대용 디바이스에 무선으로 전원을 공급할 수 있는 전원 공급 장치 및 이를 이용한 휴대용 디바이스 거치대를 제공한다.
본 발명의 무선 전원 공급 장치는 외부로부터 전원이 공급됨에 따라 교류전류 및 자기장을 발생시키는 교류/자기장 발생부 및 교류/자기장 발생부에서 형성된 교류전류에 따라 발생되는 유도 전류를 직류전류로 변환하고, 교류/자기장 발생부에서 형성된 자기장에 따라 자화되는 유도전류/자기장 발생부를 포함하여, 휴대용 디바이스에 무선으로 전원을 공급함으로써 자동차 내의 환경을 정돈된 상태로 유지할 수 있고, 휴대용 디바이스로 전원을 공급하기 위한 자기장의 발생 범위를 협소하게 함으로써, 사용자의 건강이나 다른 자성 물질에 가해지는 악영향이 최소화된다.

Abstract: A wireless power supplier and a portable device holder using the same are provided to supply the power to the portable device in a wireless manner by generating the magnetic field acting in the narrow area. A wireless power supplier(10) comprises an alternating current/magnetic field generating part(12) and an inducing current/magnetic field generating part(14). The alternating current/magnetic field generating part generates the alternating current and magnetic field according to the status of electric power supply from the outside. The inducing current/magnetic field generating part converts the generated inducing current into the direct current. The inducing current/magnetic field generating part supplies the direct current to the portable device.

Abstract: A method for measuring the contamination level of soil contaminated by oil is provided to increase the reliability of the measured value and be applied in accordance with the domestic soil environment and industrial environment by applying adequate tracer materials. A method comprises the steps of: (a) installing an injection wall(10) and an extraction wall(20) on an area contaminated by oil such as diesel, kerosene, and aircraft oil; (b) injecting clean water into the injection wall and then extracting it from the extraction wall so as to embody the steady flow state of forming the straight line fluid flow from the injection wall to the extraction wall; (c) injecting 2-ethyl-1-butanol and hexanol as partitioning tracer materials into the injection wall; (d) analyzing each concentration of the 2-ethyl-1-butanol and hexanol detected from the extraction wall; and (e) quantitatively evaluating the oil contamination degree of the ground by the analysis of the concentration.
