Patent number: 11595084Abstract: A system may include a fastener having a trench formed in a side of a head of the fastener. The system may further include a magneto-elastic component spanning the trench and attached to the head of the fastener on both sides of the trench. The system may also include a coil wrapped around the magneto-elastic component between both sides of the trench. The system may include a radio frequency identification (RFID) circuit, where the coil may be electrically connected to the RFID circuit resulting in a resonance response frequency that is a function of a strain level applied to the magneto-elastic component.Type: GrantFiled: February 2, 2021Date of Patent: February 28, 2023Assignee: The Boeing CompanyInventors: Chia-Ming Chang, Hyok J.

Patent number: 11530762Abstract: A fitting assembly configured to visibly indicate nut tightness when coupling a first component to a second component is disclosed. The fitting assembly comprises a nut comprising a threaded portion and a chamber portion, wherein the chamber portion comprises one or more through-holes. The fitting assembly also comprises an indicator slidably disposed within the chamber portion, a retainer assembly disposed within the chamber portion and configured to interlock with an inner surface of the nut, and a spring disposed within the chamber portion between, and engaging, the indicator and the retainer assembly. The retainer assembly is configured to interface with the spring to retain the spring within the chamber portion. The fitting assembly is configured to receive the first component and the second component such that, when the nut is rotated, a visibility of the indicator through the one or more through-holes changes.Type: GrantFiled: November 5, 2019Date of Patent: December 20, 2022Assignee: The Boeing CompanyInventors: Ryan K.

Publication number: 20210271369Abstract: A system for affixing a fastener or fastener collar is provided including a handheld tool configured to engage a corresponding fastener; a communication device affixed to the handheld tool and configured to communicate with a base station; and a computer. In some example implementations, the computer is configured to receive an identification of a position of the handheld tool within a region of three-dimensional space, and determine, based on the position of the handheld tool and a user input, a location of the corresponding fastener. A digital representation of the region of three-dimensional space with an identification of the location of the corresponding fastener can then be generated; along with a graphical user interface including a visual representation of the map of the three-dimensional space and a visual representation of the location of the corresponding fastener.Type: ApplicationFiled: February 27, 2020Publication date: September 2, 2021Inventors: Kurt Webster, Donald W.

Patent number: 11045985Abstract: A seal molding system includes a mold body having a mold body inner geometry configured complementary to a fitting outer geometry of a fitting, and a mold collar having one or more mold collar engagement elements configured to engage with one or more fitting engagement elements. The mold collar is couplable to the mold body at a body-collar interface allowing free rotation of the mold collar relative to the mold body. The body-collar interface is configured such that axial motion in a first axial direction and/or rotational motion in a first rotational direction of the mold collar relative to the fitting causes the mold collar to urge the mold body against a panel surface, and axial motion in a second axial direction and/or rotational motion in a second rotational direction of the mold collar relative to the fitting causes the mold collar to draw the mold body away from the panel.Type: GrantFiled: August 2, 2018Date of Patent: June 29, 2021Assignee: The Boeing CompanyInventors: Kareem Gamal Eldin Shehab, Donald W.
