  • Publication number: 20240343923
    Abstract: Concentrated dispersions of silver nanowires are used to prepare qualitatively distinct silver structures with a range of properties. The concentrated dispersions can have a high weight percent of silver nanowires and can be formulated to be flowable liquids or non-flowing pastes. The concentrated dispersions can be stable with no visible settling over the course of a week, can have non-Newtonian rheology, and can be diluted to a desired weight percent of silver nanowires without detrimental effects on the uniformity of the dispersions. The concentrated dispersions can be formulated with or without polymers or pre-polymer components. The concentrated dispersions can be formulated with silver salts to adjust dispersion of the silver nanowires and to improve electrical conductivity of cured silver structures formed from the dispersions. Methods for forming the concentrated dispersions are described as are methods to form silver structures from the dispersions.

  • Patent number: 10711786
    Abstract: A micro pumping mechanism is proposed to generate flow in micro channels of micro fluidic devices and three dimensional microprocessors cooled by the flow of coolant fluids. The proposed micro pump comprises a rotating disk inside a chamber, which overlaps with the fluidic micro channel. The rotating disk induces a shear flow across the micro channel, transporting fluid elements in the direction of the rotation of the disk. The disk can be rotated by external magnetic or electric fields as in direct drive, induction, or electrostatic motors.

  • Patent number: 10635205
    Abstract: This invention disclosure addresses the fabrication of deformable microstructured and textured sheets of transparent materials such as glass. The flexible structures have islands of arbitrary geometrical shapes interconnected by springs. Structuring is performed using ultrafast laser pulses and specially designed post-processing. The fabrication process does not create any cracks perpendicular to the cut lines, and therefore, resulting deformable structures are capable of sustaining static and cyclic in-plane tensile and compressive forces, bending moments and twisting torques. Flexible structures of this invention, fabricated using thin sheets of glass, can deform to complex surfaces through stretching, compression and folding in all directions.

  • Patent number: 10503042
    Abstract: A liquid crystal optical device is provided including at least two LC cells. A first LC cell layer has a predominant director orientation imparting a transversally non-uniform phase delay to a first polarization of an unpolarized incident light field passing therethrough while incident light of a second polarization orthogonal to the first light polarization passes therethrough undergoing transversally uniform phase delay. The first LC cell is configured to project a center extraordinary ray onto an optical axis of the device at the image surface. A second LC cell layer has a predominant director oriented orthogonally to the other predominant director in a plane perpendicular to the optical axis. The second LC layer imparts a transversally non-uniform phase delay to the second polarization of the incident light passing therethrough, the second LC cell being configured to project a center ordinary ray onto the optical axis at the image surface.

  • Publication number: 20180101051
    Abstract: A variable liquid crystal optical device for controlling the propagation of light has one or more transparent thin-film highly-resistive layer (HRL) coupled to a substrate and an electrode structure. The HRL has core layer and a cover or proximity layer, wherein the core layer material has a higher electrical conductivity and higher refractive index than the cover layer material; and wherein the core and cover layer materials have substantially the same free energies of formation of oxide. In this way, the electrode structure will be environmentally stable and responsive to an applied electrical current to generate a spatially non-uniform magnetic field.

  • Patent number: 9910246
    Abstract: An auto-focus system employing a tunable liquid crystal lens is provided that collects images at different optical power values as the liquid crystal molecules are excited between a ground state and a maximum optical power state tracking image focus scores. An image is acquired at a desired optical power value less than maximum optical power established with the liquid crystal molecules closer a fully excited state than the maximum optical power state having the same image focus score. This drive signal employed during image acquisition uses more power than was used to achieve the same optical power value during the auto-focus scan, while actively driving the liquid crystal molecules is fast. A pause due to image transfer/processing delays after acquisition is employed to allow slow relaxation of the liquid crystal molecules back to the ground state in preparation for a subsequent focus search.
