Patent number: 11174400Abstract: A method of manufacturing a nanocomposite GRIN optical-element. The method comprises providing a volumetric gradient refractive profile and providing a plurality of nanocomposite-inks to form the GRIN optical-element. Each of the plurality of nanocomposite-inks have nanoparticles dispersed in an organic-matrix. The plurality of nanocomposite-inks comprising of a nanoparticle diffusion inhibiting nanocomposite-ink wherein nanoparticle diffusion is inhibited with respect to another of the plurality of nanocomposite-inks. The diffusion inhibiting nanocomposite-ink having a different dielectric property from at least one of the other plurality of nanocomposite-inks. The plurality of nanocomposite-inks also comprising a nanoparticle diffusion permitting nanocomposite-ink wherein nanoparticle diffusion is permitted with respect to at least another of the plurality of nanocomposite-inks.Type: GrantFiled: September 23, 2015Date of Patent: November 16, 2021Assignee: VADIENT OPTICS, LLCInventors: George Williams, John Paul Harmon, Charles G.

Patent number: 10587063Abstract: A support assembly comprises a support device and a plurality of press-fit contact pins. The support device has a preformed body with a first row of slits or holes and a second row of slits or holes. The press-fit contact pins each have a contact portion at a first end and a press-fit portion at a second end opposite the first end. Each of the contact pins is disposed in one of the slits or holes of the first row or the second row with the press-fit portion protruding from a first side of the support device and the contact portion protruding from a second side of the support device opposite the first side. The press-fit portions of the contact pins disposed in the first row of slits or holes are aligned with the press-fit portions of the contact pins disposed in the second row of slits or holes.Type: GrantFiled: March 29, 2018Date of Patent: March 10, 2020Assignee: Tyco Electronics France SASInventors: Frederic Nicolas Viloteau, Mounir Alaya, Ngoc Thanh Nguyen, Alain Dupuis

Patent number: 9855752Abstract: 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.Type: GrantFiled: December 16, 2016Date of Patent: January 2, 2018Assignee: Vadient Optics, LLCInventors: George Williams, John Paul Harmon, Charles G. Dupuy, Ngoc Thanh Nguyen, Sang-ki Park, Bradley J. Hermens
