  • Patent number: 11822165
    Abstract: A display may have display layers that form an array of pixels. An angle-of-view adjustment layer may overlap the display layers. The angle-of-view adjustment layer may include an array of adjustable light blocking structures formed from electrochromic material. The electrochromic material may be interposed between first and second electrode layers. When it is desired to operate the display in a private viewing mode, control circuitry may apply a current to the first and second electrodes that causes the electrochromic material to become more opaque, thereby restricting the angle of view of the display. When it is desired to operate the display in a public viewing mode, control circuitry may apply a current to the first and second electrodes that causes the electrochromic material to become more transparent, thereby opening up the angle of view of the display.

  • Publication number: 20230145232
    Abstract: Interfacial convective assembly can assemble any type of nanoparticles or other nanoelements in minutes to form microscale and nanoscale patterns in vias or trenches in patterned substrates. The nanoelements can be assembled on both hydrophilic and hydrophobic surfaces. Nanoparticles can fuse during the process to provide solid or single crystalline electrical circuit components.

  • Patent number: 11220756
    Abstract: A variety of homogeneous or layered hybrid nanostructures are fabricated by electric field-directed assembly of nanoelements. The nanoelements and the fabricated nanostructures can be conducting, semi-conducting, or insulating, or any combination thereof. Factors for enhancing the assembly process are identified, including optimization of the electric field and combined dielectrophoretic and electrophoretic forces to drive assembly. The fabrication methods are rapid and scalable. The resulting nanostructures have electrical and optical properties that render them highly useful in nanoscale electronics, optics, and biosensors.

  • Publication number: 20190211467
    Abstract: A method for high rate assembly of nanoelements into two-dimensional void patterns on a non-conductive substrate surface utilizes an applied electric field to stabilize against forces resulting from pulling the substrate through the surface of a nanoelement suspension. The electric field contours emanating from a conductive layer in the substrate, covered by an insulating layer, are modified by a patterned photoresist layer, resulting in an increased driving force for nanoelements to migrate from a liquid suspension to voids on a patterned substrate having a non-conductive surface. The method can be used for the production of microscale and nanoscale circuits, sensors, and other electronic devices.

  • Patent number: 9771937
    Abstract: A spiral compressor may include a stationary first spiral member and an orbiting second spiral member intermeshing with the first spiral member. The spiral compressor may include a pendulum slide mechanism that may have an inner ring and a stationary outer ring connected to the inner ring via a plurality of pendulums. The pendulum slide mechanism may include an eccentric member disposed on a radial inside of the inner ring with respect to a central access of the inner ring. The inner ring on an inner circumferential side may be drivingly connected to the eccentric member and on an outer circumferential side may be rigidly connected to the second spiral member. The second spiral member may transmit an orbiting motion in relation to the first spiral member via the pendulum slide mechanism when the eccentric member is driven.

  • Patent number: 9548242
    Abstract: The invention provides a fast, scalable, room temperature process for fabricating metallic nanorods from nanoparticles or fabricating metallic or semiconducting nanorods from carbon nanotubes suspended in an aqueous solution. The assembled nanorods are suitable for use as nanoscale interconnects in CMOS-based devices and sensors. Metallic nanoparticles or carbon nanotubes are assembled into lithographically patterned vias by applying an external electric field. Since the dimensions of nanorods are controlled by the dimensions of vias, the nanorod dimensions can be scaled down to the low nanometer range. The aqueous assembly process is environmentally friendly and can be used to make nanorods using different types of metallic particles as well as semiconducting and metallic nanotubes.
