| 61 | BLUNT IMPACT INDICATOR METHODS | EP15174164.2 | 2015-06-26 | EP2977737A2 | 2016-01-27 | GEORGESON, Gary E.; TAPIA, William Joseph |
Systems and methods using fluid-filled hollow microspheres to assist in monitoring or indicating high-energy blunt impacts on structures such as aircraft. A multiplicity of microspheres may be adhered to or embedded in a coating applied on a surface of a substrate (e.g., a tape or an appliqué), which substrate in turn can be adhered to a surface of a structure to be monitored. The microspheres are designed to rupture at one or more specified pressure thresholds. In some embodiments, the microspheres are filled with electrically conductive fluid which, if released from ruptured microsphere, changes the electromagnetic state of the substrate. In response to the detection of a sufficiently large change in the electromagnetic state of the substrate, a blunt impact indication is generated. The impact site may then undergo nondestructive inspection.

| A linear impact switch provides a contact closure, when pressure-activated at any of multiple locations over substantial distances and surface areas. Preferred switch units are positioned with their impact faces in a generally vertical orientation to receive generally horizontal forces. The switch units may be used to trigger an alarm in a falling rock or slide area, wherein the switch units are placed beside a road, path, or other perimeter, for example, on a barrier, fence, retaining wall, or other structure. The switch units may be simple and durable, using a conductive outer (or forward) member and a conductive inner (or rearward) member, whereby the impact/pressure forces the outer/forward member to make contact with the inner/rearward member, thereby closing the switch to send or relay a signal notifying drivers or authorities of the event that caused the signal, even though the event may be in an isolated or seldom-inspected region. | ||||||
