Abstract

Provided is a method for enabling a semiconductor test system for testing field programmable gate arrays (FPGAs) to operate as a device programmer by converting a serial vector format (SVF) file containing a bitstream and converting the file to a vector compatible with the semiconductor test system. When executed on an HP93K test system, as an example, the vector generates JTAG (Joint Test Action Group) signals, which program the bitstream into a Field Programmable Gate Array (FPGA). The inventive method eliminates the need for a separate computer system that is normally required to run FPGA programming software and also eliminates the need to use FPGA vendor provided JTAG programming pods. Eliminating the need for the vendor software, a separate computer system, and programming pods reduces equipment cost, maintenance, and streamlines the electrical test, evaluation, and characterization of FPGAs.

Abstract

Exemplary inventive practice provides a structure that is attributed with superior resistance to loading. For example, an inventive structure includes two coaxial axisymmetric (e.g., cylindrical) shells and a granulation-filled matrix material occupying the peripheral space between the shells. According to some inventive embodiments, the granulation-filled matrix material has a loading-responsive matrix (e.g., shear-thickening fluid or highly rate-sensitive polymer) and granules dispersed therein. When the inventive structure encounters pressure loading at its exterior shell, the consistency of the loading-responsive matrix becomes thicker or firmer and thereby promotes, among the granules, interactive mechanisms (e.g., friction and/or arching) that reinforce the granulation-filled matrix material. According to some inventive embodiments, the granulation-filled matrix material has a magnetic-field-responsive matrix and magnetizable granules dispersed therein, and is magnetically fortified via application of a magnetic field (e.g., continuously applied where the matrix is magnetorheological fluid, or temporarily applied where the matrix is rheological fluid containing diamagnetic particles).

Abstract

An exemplary inventive optimization model delineates a three-dimensional geometric environment for situation therein of electromagnetic sources and an electromagnetic sensor array used for measuring electric and magnetic fields emanating from the electromagnetic sources. Based on measurements and computations relating to electrical, magnetic, and structural physical properties, the geometric environment is stratified into air, sea, and seafloor regions as well as into electromagnetically distinct zones. The design of the electromagnetic sensor array is optimized through an iterative process involving successive determinations as to how well the electric and magnetic fields emanating from the electromagnetic sources may be calculated based on measurements taken in the geometric environment by the electromagnetic sensor array. Every instance of the electromagnetic sensor array in the iterative process is uniquely located and/or uniquely configured vis-à-vis every other instance. Design optimization can be performed with respect to various frequencies or frequency ranges.

Abstract

The main components of an exemplary inventive simulation are a towing platform (such as a ship), a towed body, an underwater vehicle (such as a UUV), and a tow cable connecting the towing platform and the towed body. An objective of the dynamic arrangement of the components is to perform a “line capture” of the moving vehicle by the cable. Respective motions and positions of the towing platform and the towed body affect the cable. Waves and currents in the water, as well as changes in catenary and tension of the cable, affect the tow body. Advantageously, the invention more accurately accounts not only for continuities, but also for discontinuities, characterizing the dynamic interrelationships between and among the components. Among the invention's features is its ability to “trigger” consideration of certain dynamic manifestations relating to the vehicle, depending on whether or not the vehicle is in a captured state.

Abstract

An apparatus and method to magnetically align fibers in a base additive material during an additive manufacturing process for material property enhancing purposes or to facilitate joining of multiple types of materials during the additive process to form an integrated part. The magnetically alignable fibers are positioned through the application of a controlled, multi-axis positioning magnetic field during the additive-material layer deposition phase. This allows the fibers to be embedded within the base additive-material in any three-dimensional desired orientation, and the orientation to be varied from layer to layer, to permit directional enhancement of material properties, dependent on the nature of the fiber materials themselves. Likewise, joining of multiple types of materials may be improved through the controlled deposition of such fibers embedded within the base material itself during the additive-process between layers of two or more dissimilar materials, to provide a directionally aligned mechanical attachment between layers of base additive materials to result in a strengthened consolidated part at the conclusion of the additive manufacturing process.

Abstract

A system for gas extraction is provided with a flap valve coupled to a bore with a pivot axis offset from an axis of the bore. The valve includes a higher mass on a shorter side of the pivot axis. A valve surface on the shorter side is inclined above a horizontal plane when the valve closes. The valve opens during liquid and gas flow to extract gas from the flow. As liquid flows over the valve, the valve is forced to close. The center of gravity of the valve relative to the offset pivot point ensures that the valve remains closed during liquid flow. As gas flows over the valve, closing forces are reduced and under internal vacuum, the mass distribution about the offset pivot axis allows the flap of the valve to tilt; opening the valve and allowing gas to enter the bore.

Abstract

Embodiments employ venting features and damping components both inside and concentric to a fuzewell to improve munition fuze survivability. Damping components are selected based on their densities and stiffness properties. A shock damping liner with longitudinal grooves is affixed to an inner surface of the fuzewell and envelops the fuze. At least one shock damping collar constrains and attenuates shack experienced by the fuze. A shock damping ring is concentric about the outer surface of the fuzewell and attenuates shock, between the outermost munition system layer (the casing) and the fuzewell. Longitudinal vents in the fuzewell wall and radial apertures oriented transverse to the longitudinal vents are used for off-gassing. The venting and component orientation combination provides increased damping, resulting in impedance mismatches across multiple interface surfaces in the munition, which reduces shock vibrational pressures and stresses transferred to the fuze.

Abstract

Embodiments are directed to direct impingement cook-off mitigation systems. As assembled, a munition fuzewell is torqued into the aft end of a munition. During a cook-off event, the expanding gases from the booster energetic will burn instead of detonating. The hot expanding booster gases are vented to the munition's main fill energetic causing the main fill energetic to burn concurrently with the booster energetic. The combined expanding gases from both the booster and main fill energetics are then vented through longitudinal vents.

Abstract

An exemplary inventive subordinate oscillator array (SOA) includes two or more vibration attenuation devices (oscillators) that are sequentially arranged (e.g., via beams in the SOA) so that their respective anti-vibratory influences overlap. To design the SOA, an optimal number N of oscillators is calculated according to the equation N=ηQΔ, where η is the modal overlap, Q is the quality factor, and Δ is the desired fractional bandwidth. Each oscillator is akin to a conventional dynamic vibration absorber (DVA) and is characterized by its own mass, stiffness, damping, and geometry (e.g., length, width, and height). The respective characteristics of the oscillators are selected and the oscillators are distributed so that the SOA, when suitably attached to a vibrative structure, attenuates the vibrations of the structure so as to approximately flatten the structure's vibrations over a frequency band of interest.

Abstract

A method is provided for increasing accuracy in measuring complex Young's modulus and complex shear modulus of a material using a processing system. The material is tested to obtain an experimental frequency response transfer function of normal displacement to input force. A model panel is developed in the processing system as a modeled frequency response transfer function. The modeled transfer function is used at a range of fixed frequencies to calculate displacements of the model panel divided by the input force while varying material parameters. The modeled frequency response transfer function is compared with the experimental frequency response transfer function to compute error function values. These values indicate the most accurate material property values as those minimizing the computed error function values.

Abstract

The ESPAR antenna switches to Track Mode to maintain the null in the spatial direction of the jamming RF noise until the jamming RF noise is not present. The ESPAR antenna then returns to operating in Normal Mode.

The dimensions of buoy antenna assembly are determined by selecting a center design frequency followed by a calculation of the corresponding wavelength in the material of the hub and the vanes.

Abstract

A microelectronic device that is radiation hardened through the incorporation of a quantum structure getter (QSG) is provided. The device, such as a field effect transistor (FET) includes a conductive channel and a material stack comprising: a capping layer, one or more barrier layers comprising a high band gap, one or more quantum structures comprising a small band gap, and a substrate. The quantum structures are positioned in close proximity to the conductive channel to form a quantum well charge getter. The getter forms a low energy area beneath the FET, which traps and confines electron-hole pair wave functions produced from ionizing radiation, causing the wave functions overlap, recombine, and produce light emission. The quantum structures getter the wave functions, which reduces the ionized photocurrent that reaches the conducting channel, thereby hardening the microelectronic device against ionizing radiation.
