Abstract: According to a first aspect, a method of designing a radome may include defining a set number N of flight paths FPN, where each flight path FPN is between a first city and a second city, determining a Looking Angle Distribution (Lα-Dist) for each flight path FPN, calculating a Combination Looking Angle Distribution (Combo-Lα-Dist) for the set number N of flight paths FPN, determining a Combination Incidence Angle Distribution (Combo-Iα-Dist) corresponding the Combo-Lα-Dist, and tailoring at least one radome shell structural component of the radome to minimize electromagnetic degradation of electromagnetic waves intersecting the radome at angles within the Combo-Iα-Dist.

Abstract: A tube can include a sidewall defining a lumen profile. The sidewall can include a plurality of alternating thin regions and thick regions. The lumen profile can include a plurality of alternating large radius and small radius regions. The thin regions or large radius regions can include elastic instabilities adapted to form an essentially complete closure of the lumen profile at minimal compression.

Abstract: An annular seal including a body defining a central lumen and a weakened portion disposed around the central lumen. In an embodiment, the weakened portion includes at least one aperture or a plurality of apertures. In a further embodiment, the apertures may be identical to one another. An annular seal including a body defining a central lumen bounded by a sidewall, wherein the body has a dual-elastic modulus profile including a first elastic modulus, S1, as measured along the sidewall prior to assembly with an inner component, and a second elastic modulus, S2, as measured along the sidewall after assembly with the inner component, and wherein the first elastic modulus is less than the second elastic modulus.
