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: 11769940Abstract: An electronic device includes a display, and a housing at least partially surrounding the display and comprising a first housing member defining a first portion of an exterior surface of the electronic device and a second housing member defining a second portion of the exterior surface of the electronic device and configured to function as an antenna. The electronic device also includes a joining structure positioned between the first housing member and the second housing member including a reinforcement plate and a molded element at least partially encapsulating the reinforcement plate and engaged with the first housing member and the second housing member, thereby retaining the first housing member to the second housing member.Type: GrantFiled: December 7, 2021Date of Patent: September 26, 2023Assignee: APPLE INC.Inventors: Nicholas A. Renda, Carlo Catalano, Chen Wang, David R. Cramer, Kellen M. Atom, Lindsay D. Corbet, Melody L. Kuna, Robert J. Durand, Stephanie L. Ternullo, Sunita Venkatesh, Suvrat Lele, Wang Chung Alston Cheung

Publication number: 20230208079Abstract: Cowlings described herein for board-to-board connectors can provide high stiffness, low weight, and low total cost. Such cowlings can provide ribs with increased thickness for targeted stiffness to resist bowing in a given direction. The layers of the cowlings can include carbon fiber extending in directions parallel to the ribs in some layers and transverse to the ribs in other layers. The layers can be formed together within a mold tool that shapes the fibers into the ribs.Type: ApplicationFiled: November 22, 2022Publication date: June 29, 2023Inventors: Noell G. JOHNSON, David R. CRAMER, Sina BIGDELI, Edward S. HUO, Jeremy C. FRANKLIN, Jason C. SAUERS

Patent number: 9162434Abstract: A system and method for making advanced composite laminates includes a tape dispensing system, a tape placement head, and a tooling surface. Tape sections are formed and moved through a tape section guide using a gripping assembly. The tape section guide system is suspended over the tooling surface. Once the tape section is positioned over a desired location on the tooling surface, a tape tacking device tacks or otherwise attaches the tape section to the tooling surface or another underlying tape section.Type: GrantFiled: July 25, 2012Date of Patent: October 20, 2015Assignee: Dieffenbacher GMBH Maschinen-und AnlagenbauInventors: David R. Cramer, Don O. Evans, Christina M. McClard, Dennis L. Weinman

Patent number: 8992715Abstract: An embodiment of the present invention provides a method for manufacturing a composite preform from tape material, including feeding a tape section into a tape section guide that suspends the tape across a tooling surface, moving at least one of the tape section guide and the tooling surface relative to each other to position the tape section at a desired location and orientation relative to the tooling surface, moving the tape section toward a pre-existing tape section disposed on the tooling surface, and tacking the tape section to the pre-existing tape section. A corresponding apparatus for manufacturing composite preforms is also disclosed.Type: GrantFiled: March 27, 2013Date of Patent: March 31, 2015Assignee: Dieffenbacher GmbH Maschinen-und AnlagenbauInventors: David R. Cramer, Neal J. Beidleman, Colin R. Chapman, Don O. Evans, Michael K. Passmore, Michael L. Skinner
