摘要:
A composition includes a filler dispersed in a polymeric matrix. The filler may be electrically conducting in a temperature range and may have a Curie temperature. The composition may have a trip temperature at which electrical resistance of the composition increases with increase in temperature, and the trip temperature of the composition may be determined by the Curie temperature of the filler. The filler may be present in the polymeric matrix in an amount determined by a property of one or both of the polymeric matrix or the filler. An associated method is provided.

摘要:
A method for use in determining the thickness of a layer of interest in a multi-layer structure. A first electrode is positioned in contact with a first surface of the multi-layer structure, and a second electrode is positioned in contact with a second surface of the multi-layer structure. The second surface is substantially opposite the first surface. The first electrode is pressed against the multi-layer structure at a predetermined sampling pressure, and the structure is optionally adjusted to a predetermined sampling temperature. The electrical impedance between the first electrode and the second electrode is measured.

An ablative arc suppression device (10) includes a first region (16) having a first electrical arc ablation characteristic and a second region (18) having a second electrical arc ablation characteristic. The first region and the second region are configured for defining an opening (22) extending through the first region and the second region for confining an arc initiation region (24) of an electrical arc (26) to be generated within the opening. The first region and the second region are further configured for defining the opening so that the electrical arc is exposed to both the first region and the second region before exiting the opening.
