Abstract: An architecture for an optoelectronic oscillator uses Stimulated Brillouin Scattering (SBS) to seed, filter and amplify the oscillation signal in an overlapped oscillator loop for both a RF modulated optical sideband and a SBS signal. By phase matching the RF modulated optical sideband generated by SBS with the SBS signal, the feedback will collapse the bandwidth of the SBS signal and in turn the bandwidth of the Brillouin frequency signal, which also serves as a filter to filter out multiple undesired OEO loop modes. The embodiments herein result in reduced phase noise and increased stability.

Abstract: A structural capacitor having a plurality of planar dielectric layers and a plurality of positive and negative electrodes with the positive and negative electrodes alternating between each dielectric layer and methods for making structural capacitors are provided. First and second spaced apart holes are provided through each dielectric layer as well as the electrodes so that the first holes in the electrodes register with the first holes in the dielectric layer and likewise for the second holes. The capacitor is formed by stacking the dielectric layers and electrodes on two spaced apart alignment pins with a positive alignment pin extending through the first holes and a negative alignment pin extending through the second holes in the dielectric layers and electrodes. These alignment pins maintain layer alignment during subsequent thermal and pressure processing to bond together the dielectric and electrode layers into an integral structural material. After processing, the alignment pins are removed and replaced with electrode pins, where the positive electrode pin is in electrical contact only with the positive electrodes and the negative electrode pin is in electrical contact only with the negative electrodes. The electrode pins are used for subsequent electrical and mechanical connectorization to the structural capacitor.

Abstract: Integrated non-linear complex oxide (NLCO) thin film artificial structures include tailored microstructural and crystalline phases for designed material architectures and a method of fabrication. A nano-scale poly crystal-amorphous composite film includes an amorphous matrix surrounding crystalline domains/inclusions of the form of particles, platelets, rods and/or needles, etc. Artificial thin film layered material configurations include bilayers, repeat “unit cell” bilayers with variable stacking periodicity (N), and multilayers whereby each individual layer, ni, exhibits a different microstructural crystallinity phase state, hence the microstructural phase state is variable in the vertical direction perpendicular to the substrate. NLCO elements can be organized in array configurations. The method to create the integrated NLCO thin film artificial structures combines metal-organic solution deposition (MOSD) film fabrication and microwave irradiation (MWI) processing, is tailorable and creates artificial thin film material structures composed of differing microstructural crystalline phase states simultaneously within a single thermal treatment step.

Abstract: A thermoplastic filament comprising multiple polymers of differing flow temperatures in a geometric arrangement and an interior channel containing a structural or functional thread therein is described. A method for producing such a filament is also described. Because of the difference in flow temperatures, there exists a temperature range at which one polymer is mechanically stable while the other is flowable. This property is extremely useful for creating thermoplastic monofilament feedstock for three-dimensionally printed parts, wherein the mechanically stable polymer enables geometric stability while the flowable polymer can fill gaps and provide strong bonding and homogenization between deposited material lines and layers. These multimaterial filaments can be produced via thermal drawing from a thermoplastic preform, which itself can be three-dimensionally printed. Furthermore, the preform can be printed with precisely controlled and complex geometries, enabling the creation of a filament or fiber with an interior thread contained within the outer, printed filament or fiber. This thread adds structural reinforcement or functional properties, such as electrical conductivity or optical waveguiding, to the filament.

Abstract: Conventional gas turbine engines are generally optimized to operate at nearly a fixed speed with fixed blade geometries for the design operating condition. When the operating condition of the engine changes, the flow incidence angles may not be optimum with the blade geometries resulting in reduced off-design performance. By contrast, according to embodiments of the present invention, articulating the pitch angle of turbine blades in coordination with adjustable nozzle vanes improves performance by maintaining flow incidence angles within the optimum range at all operating conditions of a gas turbine engine. Maintaining flow incidence angles within the optimum range can prevent the likelihood of flow separation in the blade passage and also reduce the thermal stresses developed due to aerothermal loads for variable speed gas turbine applications.

Abstract: Embodiments of present inventions relate to low-profile, tapered cavity broadband antennas. One important aspect of the invention (although not the only) is the incorporation of a tapered lateral sidewalls in the antenna cavity. More particularly, according to various embodiments, a low-profile, tapered cavity antenna may comprise: an aperture defining an opening to a cavity; and an interior space defined by the cavity which is formed of a flat bottom wall defining a ground plane, and a pair of spaced-apart, tapered lateral sidewalls extending away from the flat bottom wall in opposite directions toward the aperture. The tapered shape of the tapered lateral sidewalls are specifically configured to maintain a constant resonance frequency within the cavity. In some embodiments, an isotropic high index medium material is at least partially loaded within the tapered cavity. Also, antenna may include a single or two-input port.

Abstract: An antenna having an elongated housing open at one end and defining an interior chamber. A telescoping mast has a carrier attached at a first end and a flexible antenna attached at its other end. The carrier with the attached mast and antenna is movable between a storage position in which the carrier, mast, and antenna are contained within the interior chamber of the housing, and a deployed position in which the mast and attached antenna protrude outwardly from the housing. A spring is positioned between the carrier and the housing which urges the carrier towards its deployed position. A catch mechanism selectively holds the carrier in its stored position and, when released, releases the spring to move the antenna to its deployed position.
