Patents by Inventor Bradley J. Hermens

Bradley J. Hermens 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: 11618249
    Abstract: A method of inkjet printing a gradient dielectric element in a deposition and photo-polymerization process. The method comprises: providing a plurality of complex-dielectric-inks that are inkjet printable including a nanocomposite-ink with an organic-matrix and a nanoparticle filler dispersed within. The plurality of complex-dielectric-inks have a first complex-dielectric-ink having a first photoinitiator and a second complex-dielectric-ink with a second photoinitiator. The first and second complex-dielectric-ink have different wavelength selective photo-polymerization absorption bands such that spectrally discrete exposure results in different degrees of polymerization of the first and second complex-dielectric-ink.
    Type: Grant

  • Patent number: 9855752
    Abstract: Methods of manufacturing a volumetric continuous gradient complex dielectric element with drop-on-demand techniques, such as inkjet printing, by calculating spatial placement of nanocomposite-ink droplets are disclosed. The methods comprise determining or having a multi-dimensional gradient profile representing a volumetric gradient complex dielectric element. Providing or having a plurality of nanocomposite-inks, at least one of the nanocomposite-inks having a curable organic-matrix and a concentration of nanoparticles dispersed within to print the volumetric continuous gradient complex dielectric device. A print mask is determined in one-, two-, or three-dimensions that reconstructs the multi-dimensional gradient profile as a discretized pattern based on the material properties of the plurality of nanocomposite-inks and properties of a printing apparatus with a plurality of printheads.
