Publication number: 20230375801Abstract: A head-mounted device may have optical modules that present images to a user's eyes. Each optical module may have a lens barrel with a display and a lens that presents an image from the display to a corresponding eye box. To accommodate users with different interpupillary distances, the optical modules may be slidably coupled to guide members such as guide rods. Actuators may slide the optical modules towards or away from each other along the guide rods. The guide rods may be formed from fiber-composite tubes with end caps that are fastened to a frame in the head-mounted device. The tubes may be partly or completely filled with cores to add strength. Low-friction coatings such as metal coatings may be formed on the fiber-composite tubes and the corresponding inner surfaces of the optical module structures that slidably engage the fiber-composite tubes.Type: ApplicationFiled: June 7, 2023Publication date: November 23, 2023Inventors: Ivan S. Maric, Aidan N. Zimmerman, David R. Cramer, Zechariah D. Feinberg, Samuel A. Resnick

Patent number: 11549191Abstract: Anodic oxide coatings that provide corrosion resistance to parts having protruding features, such as edges, corners and convex-shaped features, are described. According to some embodiments, the anodic oxide coatings include an inner porous layer and an outer porous layer. The inner layer is adjacent to an underlying metal substrate and is formed under compressive stress anodizing conditions that allow the inner porous layer to be formed generally crack-free. In this way, the inner porous layer acts as a barrier that prevents water or other corrosion-inducing agents from reaching the underlying metal substrate. The outer porous layer can be thicker and harder than the inner porous layer, thereby increasing the overall hardness of the anodic oxide coating.Type: GrantFiled: February 15, 2019Date of Patent: January 10, 2023Assignee: APPLE INC.Inventors: James A. Curran, Zechariah D. Feinberg, Sonja R. Postak

Patent number: 10927473Abstract: Oxide coatings that reduce or eliminate the appearance of thin film interference coloring are described. In some embodiments, the oxide coatings are configured to reduce the appearance of fingerprints. In some cases, the oxide coatings are sufficiently thick to increase the optical path difference of incident light, thereby reducing any inference coloring by the fingerprint to a non-visible level. In some embodiments, the oxide coatings have a non-uniform thickness that changes the way light reflects off of interfaces of the oxide coating, thereby reducing or eliminating any thin film interference coloring caused by the oxide coatings themselves or by a fingerprint.Type: GrantFiled: April 13, 2017Date of Patent: February 23, 2021Assignee: APPLE INC.Inventors: James A. Curran, Zechariah D. Feinberg, Christopher D. Prest, Joseph C. Poole

Patent number: 10782741Abstract: Composite coatings having improved abrasion and dent resistance are described. According to some embodiments, the composite coatings include an outer hard layer and an intermediate layer between the outer hard layer and a metal substrate. The intermediate layer can have a hardness that is less than the hard outer layer but greater than the metal substrate. In this arrangement, the intermediate layer can act as a structural support that resists plastic deformation when an impact force is applied to the coating. In some embodiments, the intermediate layer is composed of a porous anodic oxide material. In some embodiments, the outer hard layer is composed of a ceramic material or a hard carbon-based material, such as diamond-like carbon.Type: GrantFiled: March 9, 2017Date of Patent: September 22, 2020Assignee: APPLE INC.Inventors: James A.

Patent number: 10711363Abstract: A process is disclosed for minimizing the difference in thermal expansivity between a porous anodic oxide coating and its corresponding substrate metal, so as to allow heat treatments or high temperature exposure of the anodic oxide without thermally induced crazing. A second phase of higher thermal expansivity than that of the oxide material is incorporated into the pores of the oxide in sufficient quantity to raise the coating's thermal expansion coefficient. The difference in thermal expansion between the anodic oxide coating and underlying metal substrate is reduced to a level such that thermal exposure is insufficient for any cracking to result. The second phase may be an electrodeposited metal, or an electrophoretically deposited polymer. The second phase may be uniformly deposited to a certain depth, or may be deposited at varying amounts among the pores.Type: GrantFiled: December 16, 2015Date of Patent: July 14, 2020Assignee: APPLE INC.Inventors: James A. Curran, William A. Counts, Zechariah D. Feinberg

Patent number: 10669618Abstract: A method for providing a surface finish to a metal part includes both diffusion hardening a metal surface to form a diffusion-hardened layer, and oxidizing the diffusion-hardened layer to create an oxide coating thereon. The diffusion-hardened layer can be harder than an internal region of the metal part and might be ceramic, and the oxide coating can have a color that is different from the metal or ceramic, the color being unachievable only by diffusion hardening or only by oxidizing. The metal can be titanium or titanium alloy, the diffusion hardening can include carburizing or nitriding, and the oxidizing can include electrochemical oxidization. The oxide layer thickness can be controlled via the amount of voltage applied during oxidation, with the oxide coating color being a function of thickness. An enhanced hardness profile can extend to a depth of at least 20 microns below the top of the oxide coating.Type: GrantFiled: November 6, 2018Date of Patent: June 2, 2020Assignee: APPLE INC.Inventors: James A.
