20150293056 | METHOD AND DEVICE FOR SENSING A LIQUID - The invention proposes a method and device for sensing a liquid that contains positively charged particles and/or negatively charged particles. An electrical field is imposed to the liquid by applying a voltage to a positive electrode and a negative electrode disposed in the liquid, for attracting the negatively charged particles toward the positive electrode to concentrate the negatively charged particles in a first part of the liquid and attracting the positively charged particles toward the negative electrode to concentrate the positively charged particles in a second part of the liquid. A first sensing result is obtained by sensing at least one part of liquid of the first part of the liquid, the second part of the liquid, and a third part of the liquid in which the negatively charged particles and the positively charged particles are deconcentrated. Accordingly, the sensing is conducted in at least one part of liquid in which the concentration of the charged particles is changed. Since the concentration of the particles in the liquid impacts the sensitivity of the sensing of the liquid, it is possible to improve the sensitivity. | 10-15-2015 |

The heater is configured to heat the liquid such that the liquid is driven out of the container through the filter membrane. The heater can actively increase the pressure in the container by heating the liquid and/or gas in the container. Sometimes, a portion of the liquid stored in the air-tight container may be vaporized, which increases the pressure in the container as well. Under the increased pressure, the liquid can be easily driven out of the container while being purified via the filter membrane. Since the filtration is actively driven by heating, the filtration efficiency of the apparatus can be controlled and improved according to various applications. | 04-02-2015 |
