Abstract: Apparatuses for reducing migraine headache pain comprising head-contacting expanses of compressible material having pressure-versus-deflection characteristics possessing plateau conditions defined by ranges of compressive material deflections associated throughout with substantially constant material compression produced by an applied, material-compressing pressure which is slightly less than that pressure which, when applied to the anatomy, occludes anatomical, venous-return blood flow, and shells substantially surrounding, and contacting, the compressible-material expanses, appropriately sized, and operable, with the apparatuses in place on a wearers' heads, to place the compressible material in the expanse in its characteristic “plateau” condition of compression, wherein such compression, at every location, is a non-adjustable value dependent entirely upon the fit-spacing at that location between a wearer's head and the inside of the shell.

The method includes (a) supporting the anatomy with a 100% open cell viscoelastic foam, and (b) within the foam, reacting to both static and dynamic, anatomically-produced foam indentations to expand and contract cell-openness size, whereby deeper/sharper indentations result in greater-size cell-openness. Such reacting includes laterally stretching and flowing regions of the foam adjacent such an indentation The overlay structure features (1) a dynamic-response core expanse formed of a 100% open-cell, compressible and flowable, polyurethane, viscoelastic foam possessing a compressed, relaxed-state volume, and (2) an elastomeric, moisture- and gas-flow-managing coating, load-transmissively, bonded to the entirety of the core expanse's outside surface to function as a dynamically-responsive unit with the expanse.

Abstract: Barrier structure for furnishing, selectively and variously, penetration and fire-threat protection on the outside surface of a target structure. The barrier structure includes a high-elastomeric coating having an inner face bonded to such a surface, an exposed outer face, and, within this coating, at least one elastomeric layer region extending to the outer face, and containing an embedded distribution of intumescence elements.

Abstract: A ventilating and particle-filtering airflow methodology for managing the flow of air to the electrical sliding-contact zone of an on-board aircraft (vehicle) electrical generator. Conduit structure collects intaken air during aircraft (vehicle) engine operation, filters this air to capture and prevent the passage of particles, and directs filtered airflow to that brush region through a close-coupled fluid-flow connection which closes upon and substantially isolates (in terms of incoming airflow) that region. Water drainage is provided for in a region near where filtering takes place. The filtered airflow is substantially the only airflow admitted to this protected region.
