Abstract: A fastener locating tool equipped with a sensor head having one or more probes and a method for operating such a tool for precisely locating a fastener that is hidden or buried under a thick coating applied on a surface of a structure. The fastener locating tool may be manually or automatically operated. The fastener locating tool includes a platform having a central opening, means for temporarily attaching the platform to a coated surface, and a sensor head that may be easily mechanically coupled to and then later decoupled from the platform. Optionally, the fastener locating tool also includes a multi-stage positioning system with X and Y stages which may be used to adjust the position of the sensor head. The sensor head includes at least one probe which generates electrical signals indicating the presence of a fastener beneath a coating when the probe is within a detection range.

Abstract: An inverted double dome double vacuum debulk tool having separable upper and lower chamber portions which can be assembled to form a vacuum chamber. In accordance with some embodiments, the top and bottom halves each comprise a circular cylindrical sidewall closed at one end by an inverted dome. The domes may be hemispherical or semi-elliptical with convex sides facing the chamber interior space. A base plate on which the composite patch rests is removable from the vacuum chamber. Various fittings pass electrical power and vacuum into the tool and sensor outputs out of the tool.
