International Classification:

H01R012/00

US Classification:

439 70, 439 34, 439329, 439495, 439 74

Abstract:

A connector pad is provided having a base, a top opposite the base, and tapered sidewalls therebetween. The tapering minimizes stress concentrations when the connector pad is bonded into, or on the surface of a structure. The connector pad consists of a plurality of structural load carrying plies suitable for sandwiching a flat structurally integrated wiring array therebetween. A plurality of plated through holes formed in the connector pad enable access to the wiring array therein.

Assignee:

Boeing Company - Chicago IL

International Classification:

H01R 13/62

US Classification:

439329, 439493

Abstract:

An apparatus for establishing a substantially unitary connecting structure including a generally flat conductor member carrying a first plurality of first electrical conductors and a second conductor member carrying a second plurality of second electrical conductors includes: (a) an electrical connecting structure configured for receiving the second conductor member to establish electrical connection between at least one first electrical conductor of the first plurality of first electrical conductors and at least one second electrical conductor of the second plurality of second electrical conductors; (b) a generally inflexible support structure; and (c) at least one connecting member traversing the flat conductor member and cooperating with the electrical connecting structure and the support structure for capturing the flat conductor member between the connecting structure and the support structure in an installed orientation.

Jeffrey R. Kollgaard - Kent WA, US
Matthew C. Malkin - Seattle WA, US

Assignee:

The Boeing Company - Chicago IL

International Classification:

G01H 11/08
H01L 41/00

US Classification:

73649, 73632, 73761, 310322

Abstract:

Apparatus, systems, and methods for inspecting and monitoring bolted joints of metallic and composite structures for defects such as delamination and fatigue cracking are provided that incorporate ultrasonic transducers with load bearing washers. These active washers may be used for inspecting and monitoring a structure beneath such load bearing fasteners as bolts and nuts. Active washers may be used for continuous, periodic, and controlled inspections of bolted joints. Ultrasonic transducers may be permanently applied to a surface of a washer or recessed in a cavity on a surface of the washer. Inspection signals may be transmitted from ultrasonic transducers into a structure and reflected in pulse-echo application or received by another active washer on the opposing side of the structure in a through-transmission application.

Abstract:

Structural health monitoring apparatuses and methods are disclosed. One or more structural health sensors may be used to disconnect and/or connect one or more RFID chips to an antenna such that wireless communication with the one or more RFID chips (or the absence of wireless communication) through the antenna indicates the structural health status. Example structural health sensors may be moisture detecting or fracture detecting. A remote reader may be used to establish the wireless communication with the one or more RFID chips to determine the structural health. The sensors and RFID chips may be passive and powered through the wireless communication from the remote reader. Such apparatuses and methods may be applied to any large structures requiring regular inspection, such as aircraft, ships, automobiles or buildings.
