Abstract:
A magazine well plug used to render a weapon safe and/or to prevent sand, water, and other contaminants from entering a weapon is described. The magazine well plug includes a main body substantially shaped to conform to the interior of a magazine well, an optional flange substantially disposed about the main body, and an optional grip element disposed at one end of the main body facilitating insertion and removal of the plug with respect to the magazine well. The main body and flange are comprised of one or more compressible materials. The main body is dimensionally larger than one or more dimensions within a magazine well so as to require the main body to be compressed in part or whole when inserted into a magazine well. The invention avoids openings inherent with rigid plugs, thereby preventing solid and/or liquid contaminants from entering a magazine well.

Abstract:
A wearable wound simulant including a skin replica having the appearance of a particular region of the human body, examples including but not limited to a leg, arm, torso, or stomach, and a wound disposed along the skin replica is described. The skin replica includes a plurality of bendable layers arranged to replicate the visual and tactile properties of human tissues and at least one tear resistant layer comprised of a fabric material disposed between two bendable layers. The tear resistant layers are less stretchable than the bendable layers so as to prevent the bendable layers from stretching beyond their failure threshold. Design elements of the present invention facilitate the visual, tactile, and functional aspects of a battlefield wound so as to allow for the diagnosis of injuries associated therewith. Furthermore, the present invention allows for the insertion of a needle or the like, the probing and/or packing of wounds, the compression of vascular simulants to stop or limit blood loss, and the replacement of dislodged organs.

Abstract:
The purpose of quartz homeotypes grown epitaxially on beta quartz for use in pressure sensors or accelerometers is to be able to drastically cut down production costs on otherwise expensive or time-consuming to grow crystals that are necessary in various industrial applications. This is done via epitaxial growth of quartz homeotypes across the whole surface of a sample of beta quartz, an easily accessible and high temperature capable crystal. This invention also applies to the epitaxial application of piezoelectric material atop a piezoelectric crystal for the purpose of altering its piezoelectric coefficient and the epitaxial application of a piezoelectric crystal atop a host crystal for the purpose of increasing its insulation resistance.
Abstract:
The purpose of diffusion assisted crystal hydrothermal growth is to facilitate a greatly increased crystal growth rate that would save time that is precious in such a material and manpower costly process. The assisted crystal growth itself requires the utilization of a piezoelectric shaker connected to the autoclave in which most industrial hydrothermal crystals are grown. The waveform can be modulated to induce transport of nutrient in a singular direction, customized to the topology of the apparatus. As it stands currently, the growth of most crystals that require autoclaves for their production can take anywhere from 3 months to up to 2 years, and accordingly carries many costs, particularly electricity and supervision of the autoclave(s), and other issues that may arise during the growth. While the product of this labor results in high-quality crystals, in reality, these are not at all what is needed outside of the laboratory environment. Using the assisted crystal hydrothermal growth process, average crystal growth can be cut in half, with the resulting crystals consequently being of a slightly lower quality, though still sufficient for most engineering purposes. Another advantage of using a piezoelectric shaker is that an additional sensor can be added to the autoclave to monitor the health of the autoclave using trending data obtained during the growth.
Abstract:
An apparatus for improving flexibility and its method of use are provided. The apparatus features a flexible member, which can have varying degrees of stiffness and flexibility, based on user preference. Further, the apparatus features a first and second auxiliary grip, as well as a first and second primary grip. In conjunction, these grips provide a vast multitude of ways to grip the apparatus, enabling it to be used in a wide variety of stretches and exercises, promoting strength as well as joint mobility and flexibility.
Abstract:
A system generates a customized application data structure for modeling physical systems. The system includes a processor, an input device, optionally a display device, and a memory device. The processor is adapted to embed a multiphysics model data structure in the application data structure. The multiphysics model data structure comprises a representation of models of physical systems. Geometry data representing geometry subroutines and call data representing geometry subroutine calls are added to the embedded multiphysics model data structure. Data representing application features are added to the application data structure. Each application feature comprises one or more of (i) first data representing a form feature, or (ii) second data representing an action feature. A customized application data structure is generated providing a customized modeling of the physical systems using a modeling operation, a geometry of the one or more models of physical systems, an application feature, and a geometry subroutine.
Abstract:
A lightning-protected conductive composite fuel tank includes a conductive material arrayed on an outer surface to at least partially cover a fastener centerline. Through holes extend along the fastener centerline through the conductive material and the underlying fuel tank shell. These through holes are countersunk into the fuel tank shell to a depth such that a fastener in a through hole will avoid electrical continuity or communication with the conductive material on the fuel tank outer surface. The gap in the countersunk through holes, between the fastener heads and the coextensive outer surface of the fuel tank, is filled with a dielectric or nonconductive material.
