Abstract: Methods and apparatus for measuring and optionally adjusting the temperature profile of an optical window. In one example, an optical window with integrated temperature sensing functionality includes a first window layer of an optically transparent material, a second window layer of the optically transparent material, an electromagnetic interference shielding grid disposed between the first and second window layers and including a first electrically conductive structure and a second electrically conductive structure, and a thermally sensitive material disposed between the first and second electrically conductive structures, the thermally sensitive material having an electrical property that varies as a function of temperature.

Abstract: A window installation includes a phase-change filler material sealing an outer edge of the window, and coupling the window to a frame around the window. The filler material in a solid state rigidly holds the window in place. When the filler material is in a liquid state it allows the window to float in its coupling to the frame. There may be supports within the rigid material that contact the window, but allow the window to expand or contract by sliding along the supports. The installation may be useful in situations where the window is subjected to thermal shocks, or other sorts of heating. The installation may be used for a sensor window, and may be part of a hypersonic vehicle.

Abstract: A switchable wire includes filaments, each of which includes a heat-activated material layer that may be indirectly heated to change its state between different states having different electrical conductivity. In an example embodiment the indirect heating may be electrically resistance heating by passing electrical current through an electrically-resistive core of the filament. The heat passing through an electrically-insulative coating around the core, and into a heat-activated material layer around the electrically-insulative coating. The heat-activated material may be a chalcogenide material that is shiftable between a crystalline electrically-conducting state and an amorphous electrically-insulating state. The state of the material may be controlled by controlling the heating profile through controlling heating in the core. Many such filaments may be twisted together to form a switchable wire. Such wires may be used in any of a variety of devices where switchable electrical conductivity is desired.

Abstract: A conductive interconnect structure comprises a polymeric substrate (e.g., a thermoplastic) and a plurality of compliant conductive microstructures (e.g., conductive carbon nanofibers) embedded in the polymeric substrate. The microstructures can be arranged linearly or in a grid pattern. In response to heating, the polymeric substrate transitions from an unshrunk state to a shrunken state to move the microstructures closer together, thereby increasing an interconnect density of the compliant conductive microstructures. Thus, the gap or pitch between adjacent microstructures is reduced in response to heat-induced shrinkage of the polymeric substrate to generate finely-pitched microstructures that are densely pitched, thereby increasing the current-carrying capacity of the microstructures. The polymeric material can be heated to conform or form-fit to planar and non-planar surfaces/geometries, and can be selectively heated at various portions to tailor or customize the interconnect density of the microstructures at selected portions. Associated electrical conducting assemblies and methods are provided.

Abstract: A dynamic aperture is disclosed. A dynamic aperture includes a base layer, a conductive structure disposed on the base layer, and a layer of a material having a dynamically controllable electrical conductivity that is disposed over the base layer and the conductive structure. A transmission profile of the dynamic aperture is determined by a combination of the conductive structure and the layer of the material. The transmission profile is dynamically alterable by controlling the electrical conductivity of the layer of the material.
