  • Patent number: 8460532
    Abstract: The present invention provides a new method and apparatus/system for purifying ionic solutions, such as, for example, desalinating water, using engineered charged surfaces to sorb ions from such solutions. Surface charge is applied externally, and is synchronized with oscillatory fluid movements between substantially parallel charged plates. Ions are held in place during fluid movement in one direction (because they are held in the electrical double layer), and released for transport during fluid movement in the opposite direction by removing the applied electric field. In this way the ions, such as salt, are “ratcheted” across the charged surface from the feed side to the concentrate side. The process itself is very simple and involves only pumps, charged surfaces, and manifolds for fluid collection.

  • Patent number: 7910006
    Abstract: The water is at the origin of an entire series of geological and climatic processes and is primarily the basis of all forms of life. Actually, it is the majority component of all living organisms (50% to 98%); the human body contains 70% of the total mass thereof. The biosphere in its entirety consists of 80% water. Although this may be one of the most highly examined liquids, its properties comprising numerous anomalies have not yet all been elucidated. It plays an essential role in the structure and metabolism of all living beings. This biological role is due to its physical and chemical properties that are out of the ordinary. Bernal and Flower established a rule defining that each oxygen atom has two hydrogen atoms as neighbors and each hydrogen bond contains one hydrogen atom. The separation of the liquid water molecules produces the formation of hydroxyl ion (OH?) and hydronium ions (H3O+), which hampers this rule.

  • Publication number: 20080142157
    Abstract: Communication between microchannels of a microfluidic circuit is controlled through a combination between a membrane and a pin-actuated valve arrangement. The deformable membrane contributes to the formation of the surface of the microchannels. Alternatively, or in addition, the valve arrangement is operated through combination of the membrane with a control fluid. Systems, devices and methods based on such communication are shown. Also shown are methods to manufacture a system having a fluidic circuit and a control arrangement.

  • Publication number: 20080135412
    Abstract: The invention provides a system for activating an electronic paint including at least two independently movable ultrasonic transducers (20,22), an electronic brush (30) including an electronic-brush ultrasonic transducer (32), and a controller (40). The controller (40) is operably coupled to the two independently movable ultrasonic transducers (20,22) and the electronic-brush ultrasonic transducer (32). An electronic-brush location with respect to locations of the independently movable ultrasonic transducers (20,22) is determined from ultrasonic signals communicated between the ultrasonic transducers (20,22) and received by the controller (40).

  • Patent number: 6911132
    Abstract: An apparatus is provided for manipulating droplets. The apparatus is a single-sided electrode design in which all conductive elements are contained on one surface on which droplets are manipulated. An additional surface can be provided parallel with the first surface for the purpose of containing the droplets to be manipulated. Droplets are manipulated by performing electrowetting-based techniques in which electrodes contained on or embedded in the first surface are sequentially energized and de-energized in a controlled manner. The apparatus enables a number of droplet manipulation processes, including merging and mixing two droplets together, splitting a droplet into two or more droplets, sampling a continuous liquid flow by forming from the flow individually controllable droplets, and iterative binary or digital mixing of droplets to obtain a desired mixing ratio.
