Abstract: A method for acquiring, externally or internally, for utility purposes a subject's anatomical heart-sound information including (a) for a selected time period, applying continuous, near-sensor-mechanical-resonance, vibratory stimulation to an acoustic sensor placed on or within the subject's anatomy, and (b) during that time period, detecting, as direct indications of heart sounds, changes in the sensor's physical resonance properties produced by heart sounds arriving at the sensor.

Abstract: A method, and a self-sealing, layer-effect, stealth-reaction liner, for sealing against fuel leakage from the wound-punctured wall of an FT synthetic liquid fuel container. The liner includes (a) an elastomeric body defined by spaced, opposite faces, formed of a material which is non-reactive to FT fuel, and (b) nominally shrouded in a region within the liner body, inwardly of the faces, a distribution of liquid-imbiber beads which react to contact with FT fuel to initiate liquid-imbibing and material-swelling actions. The method includes (a) preparing, for installation in such a container, a liner with a non-fuel-reactive, substantially continuous-material elastomeric body having opposite faces, and (b) within that body, a non-facially exposed, normally body-shrouded, central distribution of fuel-reactive liquid-imbiber beads.

Abstract: A layered panel structure including first and second layers formed, respectively, of (a) non-thermoformable, and (b) thermoformable, fiber-strand-reinforced resin, materials, having therebetween a bonding interface formed by resin drawn from the second layer.

Abstract: A method for establishing a sprayable stream of composite material for spray-applying to a target surface to create thereon a defined composite-material coating designed for defeating a liquid leak from a puncture wound created in the wall of a container holding liquid of a particular character, where the target surface is on a side of that wall.

Abstract: A method and a system for monitoring and characterizing a person's heart condition for various medically related purposes. The method includes the steps of (a) acquiring a selected person's acoustic heart signature, (b) acquiring, substantially simultaneously, that same person's electrical heart signature, (c) choosing elements of determined interest from these two acquired signatures and selectively processing and inter- and/or cross-relating such elements, and (d) employing the results of the relating step to create a heart-condition fingerprint useful in the characterization of that person's heart condition.
