Abstract: Some embodiments include an integrated assembly having an interconnect over a first conductive structure and coupled with the first conductive structure. The interconnect includes a conductive core. The conductive core has a slender upper region and a wide lower region. The upper region joins to the lower region at a step. A liner laterally surrounds the lower region of the conductive core. The liner has an upper surface which is substantially coplanar with the step. An insulative collar is over and directly against both an upper surface of the step and the upper surface of the liner. The insulative collar laterally surrounds and directly contacts the slender upper region. A second conductive structure is over and directly against a region of the insulative collar, and is over and directly against an upper surface of the slender upper region. Some embodiments include methods of forming integrated assemblies.

Abstract: Method and apparatus for minimizing antenna backside signal response and ambiguity in low frequency applications, particularly low frequency synthetic aperture radar (SAR). Various time delay elements are selectably switched into the signal path so as to cause a null to be placed in the antenna response pattern in the direction of undesired radar returns. The means for selectably switching may be dithered so as to introduce modulation onto the undesired radar return to aid in the discrimination and removal of the undesired radar return from the SAR image during post processing.

Abstract: A protective garment including an outer shell, a thermal liner and a moisture barrier, in which the thermal liner includes a flame and heat resistant apertured closed-cell foam laminate. The apertured closed-cell foam laminate comprises a layer of apertured closed-cell foam material positioned between and bonded to a substrate of woven aramid material and a substrate of aramid material of a lesser or equal grade. The thermal liner is appreciably non-moisture absorbent and provides high thermal insulation for its weight and thickness in comparison to prior art thermal liners. Accordingly, the overall weight of the garment is minimized, as is the movement-restricting effect of the liner. The non-absorbency of the thermal liner allows the liner to be positioned between the moisture barrier and the outer shell of the garment so that the liner does not restrict flow of perspiration moisture vapor from the wearer to the moisture barrier.
