Patent number: 10572786Abstract: A reflective particle tag reader system includes a read head assembly having a camera, illuminators, and a rigid frame portion for supporting the camera and the illuminators. The illuminators illuminate a focal point located opposite the camera where a reflective particle tag is placed. A computer in data communication with the camera receives and store images of the reflective particle tag that are acquired by the camera. The computer is programmed to process video images and to quantify a positional alignment parameter and an angular alignment parameter of the reader with respect to the reflective particle tag. A rapid burst of image frames is obtained in response to the positional alignment and the angular alignment parameters being within a predetermined tolerance and identity of the reflective tag is established between a first image set and a second image set.Type: GrantFiled: September 25, 2018Date of Patent: February 25, 2020Assignees: National Technology & Engineering Solutions of Sandia, LLCInventors: Heidi A.

Patent number: 10393933Abstract: Tunable filters can use Fano metasurface designs having extremely narrow transmission bands. The Fano metasurface can comprise dielectric or semiconductor materials and can produce transmission bands with quality factors well in excess of 1000—at least a factor of 50 greater than typical metamaterial-based infrared resonances. Numerical simulations of these metasurfaces show that the spectral position of the passband can be changed by slightly changing the position of a small dielectric perturbation block placed within the near-field of the resonator by using simple electromechanical actuation architectures that allow for such motion. An array of independently tunable narrowband infrared filters can thereby be fabricated that only requires deep-subwavelength motions of perturbing objects in the resonator's near-field.Type: GrantFiled: June 15, 2017Date of Patent: August 27, 2019Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Michael B.

Patent number: 10361250Abstract: An array of dielectric resonators is formed on a substrate.

Publication number: 20190196229Abstract: Thermochromic low-emissivity films can comprise a vanadium dioxide thin film or a thin film of vanadium dioxide nanoparticles incorporated into a polymer matrix, and a layer comprising a transparent conductive oxide to modify solar heat gain, solar reflectivity and thermal resistance of windows. The thermochromic low-emissivity films transition from infrared (IR) reflective when warm, to IR transparent when cool. This dynamic reflectivity is passive by nature, and requires no electronics or power source to shift. In addition, this dynamic transition can occur at any design temperature, and when the nanoparticles are dispersed, they remain transparent in the visible spectrum during both phases.Type: ApplicationFiled: May 16, 2018Publication date: June 27, 2019Inventors: Paul G.

Patent number: 10180398Abstract: A hyperspectral imaging flow cytometer can acquire high-resolution hyperspectral images of particles, such as biological cells, flowing through a microfluidic system. A trajectory-based triggering system can be used that will only trigger the acquisition of a hyperspectral image when an appropriate particle or cell is crossing an imaging line, thereby saving valuable resources and time. The hyperspectral imaging flow cytometer can provide detailed spatial maps of multiple emitting species, cell morphology information, and state of health. An optimized system can image about 20 cells per second. The hyperspectral imaging flow cytometer enables many thousands of cells to be characterized in a single session.Type: GrantFiled: August 21, 2017Date of Patent: January 15, 2019Assignee: National Technology & Engineering Solutions of Sandia, LLCInventor: Michael B.

Patent number: 9909233Abstract: The present invention pertains to the use of mobile coherent interfaces in a ferroelectric material to interact with optical phonons and, ultimately, to affect the material's optical properties.

Patent number: 9846348Abstract: Efficient harmonic light generation can be achieved with ultrathin films by coupling an incident pump wave to an epsilon-near-zero (ENZ) mode of the thin film. As an example, efficient third harmonic generation from an indium tin oxide nanofilm (?/42 thick) on a glass substrate for a pump wavelength of 1.4 ?m was demonstrated. A conversion efficiency of 3.3×10?6 was achieved by exploiting the field enhancement properties of the ENZ mode with an enhancement factor of 200. This nanoscale frequency conversion method is applicable to other plasmonic materials and reststrahlen materials in proximity of the longitudinal optical phonon frequencies.Type: GrantFiled: February 10, 2016Date of Patent: December 19, 2017Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Ting S.

Patent number: 9799798Abstract: A novel thermal source comprising a semiconductor hyperbolic metamaterial provides control of the emission spectrum and the angular emission pattern. These properties arise because of epsilon-near-zero conditions in the semiconductor hyperbolic metamaterial. In particular, the thermal emission is dominated by the epsilon-near-zero effect in the doped quantum wells composing the semiconductor hyperbolic metamaterial. Furthermore, different properties are observed for s and p polarizations, following the characteristics of the strong anisotropy of hyperbolic metamaterials.Type: GrantFiled: December 15, 2016Date of Patent: October 24, 2017Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Ting S.
