Abstract
Official abstract text for this publication.
A structure is described that includes a first faying surface, a second faying surface for creating an electrical bond with the first faying surface, and a sensor operatively placed proximate the first faying surface and the second faying surface. The sensor includes a current port for injecting a fixed current through the electrical bond, a voltage port for sensing a voltage across the electrical bond induced by the fixed current, a processing device programmed to determine a resistance of the electrical bond based on the fixed current and sensed voltage, and a wireless interface for transmitting at least one of the sensed voltage and the determined resistance to an external device.
First claim
Opening claim text (preview).
What is claimed is: 1. A structure comprising: a first faying surface; a second faying surface for creating a micro-ohm electrical bond with said first faying surface; a bolt coupling said first faying surface to said second faying surface to create the micro-ohm electrical bond between said first faying surface and said second faying surface, wherein said bolt is configured to create the micro-ohm electrical bond between said first faying surface and said second faying surfac…
