  • Publication number: 20250082827
    Abstract: The invention relates to a double-microenvironment three-layer bionic hydrogel scaffold and a preparation method and application thereof, which are characterized in that includes a cartilage layer GL-HPKGN, an intermediate layer GL-GMA, and a bone layer GL-HP/GMAAT; by an enzymatic crosslinking reaction based on hydroxyphenylpropionic acid (HPA), kartogenin (KGN) is grafted onto gelatin to form a cartilage-specific microenvironment in GL-HPKGN; Based on hydroxyphenylpropionic acid (HPA), a dual crosslinking network was formed by enzyme crosslinking reaction and methacryloyl-glycidyl dimethicone (GMA) photo-crosslinking reaction, which was used to graft atorvastatin (AT) onto gelatin, forming GL-HP/GMAAT with bone-specific microenvironment; the intermediate layer GL-GMA was beneficial for forming a clear and defined cartilage-bone integrated structure. The introduction of the tide-line intermediate layer GL-GMA facilitated the formation of well-defined chondro-bone integrated structures.

  • Publication number: 20240353684
    Abstract: A display system may include a waveguide with an output coupler that couples image light out of the waveguide and towards an eye box. The output coupler may also transmit world light from real-world objects towards the eye box. A bias lens may pass the world light to the output coupler. An adjustable tint layer having multiple states that involve transmission of different amounts of the world light may be disposed between the bias lens and the output coupler. Different states may impart different colors and/or may impart a gradient transmission characteristic to the world light. The bias lens itself may form the adjustable tint layer. The adjustable tint layer may have a transparent electrode layer that is provided with one or more AC voltages that heat the adjustable tint layer. The adjustable tint layer may be a self-switching electrochromic device that includes a transparent solar cell.

  • Publication number: 20240151982
    Abstract: An electronic device may have a display system. The display system may include a waveguide, an input coupler, and a surface relief grating (SRG) structure. The SRG structure may be formed from a high-index material that includes titanium dioxide nanoparticles. To increase the refractive index of the high-index material, the ratio of the size of the nanoparticle core to the size of the capping layer may be increased. The high-index material may also include nanoparticles of different sizes to increase the packing density of the nanoparticles. The SRG structure may be depth modulated in a lateral direction to maximize efficiency. The SRG structure may include slanted ridges covered by an encapsulant. The SRG structure may include a blazed grating with ridges that are covered by a coating and encapsulated by an encapsulant.

The head-mounted device may have an optical system that directs the computer-generated content towards eye boxes for viewing by a user. The optical system may include a spatially addressable adjustable optical component. The adjustable optical component may have first and second electrodes and an electrically adjustable material between the first and second electrodes. The electrically adjustable material may include a transparent conductive material such as indium tin oxide that includes a pattern of segmented trenches configured to provide the transparent conductive material with electrical anisotropy. Contacts may be coupled to the transparent conductive material. Control circuitry can adjust the electrically adjustable material to form a spatially addressable light modulator or adjustable lens.

  • Publication number: 20220312614
    Abstract: An electronic device may have transparent housing structures such as walls formed of glass or sapphire. Housing structures such as transparent housing structures may have a colored coating. The colored coating may include an absorptive layer and a metal layer. The coating may exhibit a color that can be adjusted by adjusting the thickness of the thin absorptive layer. A colored layer such as a layer of colored polymer may be incorporated into the colored coating to further adjust the color of the coating. The colored coating may be formed on an inner or outer housing structure surface. The surface may have a texture to provide the coating with a matte appearance. When formed on an outer surface, a diamond-like carbon layer may protect the colored coating. When formed on an inner surface, a passivation layer may be used to prevent oxidation of the metal layer.

  • Patent number: 11327237
    Abstract: An electronic device includes a housing and a display. The housing defines an interior cavity and includes an optically-transmissive housing component. The display is disposed in the interior cavity and is viewable through the optically-transmissive housing component. An optoelectronic component is disposed in the interior cavity. An optical fiber extends between a first end positioned adjacent the optoelectronic component and a second end positioned adjacent the optically-transmissive housing component. The optical fiber defines a non-linear optical path between the first end and the second end. At least a portion of the optical fiber is laterally offset from a lateral edge of the display.

  • Patent number: 11269442
    Abstract: A transparent high-conductivity layer for providing electrostatic feedback to a user of an electronic device. The transparent high-conductivity layer is positioned over a capacitive input sensor and has a resistivity sufficiently high to prevent interference with the capacitive input sensor. As one example, the transparent high-conductivity layer can be formed from a layer of geometrically-separated regions of high-conductivity material. The average distance between geometrically-separated regions can substantially define the resistivity of the transparent high-conductivity layer.

  • Patent number: 10694607
    Abstract: An electronic device may have a housing with a display. A transparent portion of the housing may serve as a display cover layer and may overlap an array of pixels in the display. The array of pixels may form an active area of the display for displaying images for a user. An ambient light sensor window may be formed in an inactive area of the display that does not overlap pixels. An ambient light sensor may be mounted in an interior region of the housing. A metal-coated light guide may have a first end aligned with the ambient light sensor window to receive ambient light from an exterior region surrounding the device and may have a second end at which the ambient light is provided to the ambient light sensor.
