Thanh-Huong T. Do 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).

  • Publication number: 20110033696
    Abstract: The present application generally relates to the formation of a microsphere-based laser-receptive retroreflective sheeting having a thickness of less than 0. 161 mm that exhibits reduced incidence of curling during and after printing. The reduced incidence of curling results from placement of an anticurl coating on at least a portion of the retroreflective sheeting. After curing, the anticurl coating includes a cross-linked acrylic acid resin. This resulting microsphere-based, laser-receptive retroreflective sheeting can, for example, be adhered or placed adjacent to a substrate to create a form.

  • Publication number: 20090320998
    Abstract: In general the disclosure relates to manufacturing methods for producing conductive patterns on flexible substrates. For example, a layer of a metal powder composition is deposited onto an adhesive overlaying a substrate. Pressure is applied to the metal powder composition on the adhesive coated substrate web by a die having one or more projections, in order to reproduce a pattern on the substrate. The metal powder is compressed by the projections of the die, thereby densifying the powder and causing it to adhere to the adhesive in a reproduction of the die pattern. The metal powder does not adhere substantially in uncompressed regions, and may be removed. In this manner, a metal powder composition may be densified and adhered to a substrate forming a web of flexible circuit elements, for example, circuit elements such as antennas, resistors, capacitors, inductive coils, conduction pads and the like.
