US Classification:

702 38, 702116, 702182, 702183, 702188

Abstract:

Methods, systems, and computer readable media for wireless crack detection and monitoring are disclosed. According to one system, a crack detector is affixed to a surface of a material for detecting a crack in the material. In response to detecting a crack, a crack indicator is generated, indicating the existence of the crack. A mote wirelessly communicates the crack indicator to an external device. The mote may also store multiple crack indicators in local memory before being downloaded to the external device. In other embodiments, the mote may time-stamp the crack indicator for indicating a time when the crack was detected. Additionally, the mote may associate other information with the crack indicator such as temperature and acceleration information.

Abstract:

The invention provides a method for the at least partial removal of one or more polymeric coating layers from a coated substrate having at least one coated surface. The method includes generating at least one reactive species in an ionized gas stream discharged at atmospheric pressure; and placing the coated surface in the ionized gas stream. The at least one reactive species reacts with the one or more polymeric coating layers such that one or more coating layers is at least partially removed from the coated surface of the substrate at atmospheric pressure.
