Christena Nash has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10744739
    Abstract: A splash resistant multi-layered structure is provided. The structure includes a specific arrangement of layers of material and a plurality of three-dimensional spacers that helps prevent penetration through the structure by a fluid that contacts an outer surface of the structure due to a state of forced separation that exists between two adjacent layers of the structure due to the presence of the plurality of three-dimensional spacers positioned between the layers. The plurality of three-dimensional spacers can be positioned on one of the adjacent layers of the structure such that a distance at least as large as the maximum height of the plurality of three-dimensional spacers separates the two layers from each other and can be present on a layer of material in a continuous or discontinuous pattern or can be present on a layer of material in a random fashion.
    Type: Grant

  • Publication number: 20180238830
    Abstract: A magnetohydrodynamic microfluidic system and a method of pumping a fluid using a magnetohydrodynamic system are disclosed. The method includes applying at least one of an electric current and an electric voltage to a first modified electrode and a second electrode to generate an ionic current between the first modified electrode and the second electrode and to cause a current carrying species to move to or from the modified electrode, applying a magnetic field perpendicular to an ionic current vector, the magnetic field and the ionic current combining to induce flow of the fluid in a direction perpendicular to the magnetic field and the ionic current vector, and maintaining fluid flow by recharging the modified electrode.
