  • Patent number: 10524733
    Abstract: A method for improving the signal to noise ratio of an EEG signal in which a wavelet packet decomposition having a plurality of levels is first applied to a time slice of the EEG signal. A default signal is set to the first wavelet packet and a default peak response is then calculated for the first wavelet node. An update signal is set to the default signal combined with another of the wavelet nodes and an update peak response signal is then calculated of the update signal. If the update peak response signal exceeds the default peak response, the default peak response is set equal to the update peak response and the default signal is set equal to the update signal. Otherwise, the value of the current node is set to zero which effectively eliminates the signal data of the current wavelet node. These steps are reiterated for all of the wavelet nodes and, thereafter, a composite waveform of the EEG signal is reconstructed from the non-zero wavelet nodes.

  • Patent number: 10520272
    Abstract: Openings in a muzzle brake provide recoil inhibition and impulse noise attenuation by redirecting the propellant gases to the external environment. A turning vane aggressively turns and redirects the propellant gases in a rearward direction to counter the recoil of the weapon system. An angled baffle provides a physical barrier to redirect propellant gases rearward to provide additional force to counteract the recoil force. Attenuation slits mitigate blast overpressure by producing a fluid barrier of high velocity propellant gases directed radially away from the muzzle brake. The fluid barrier from the attenuation slits interacts with the redirected propellant gas from the turning vane and the angled baffle and redirects the counter recoil gases away from the crew.

  • Patent number: 10519617
    Abstract: In certain embodiments, a sand-boil filter includes a hollow, conical, water-porous structure made of a mesh material having spaced mesh holes. The filter is inserted narrow-end down into a sand boil to allow water to flow from the ground through the mesh material and out the top of the sand boil, while blocking solid matter larger than the mesh holes from passing through the mesh material. In some implementations, the filter is filled with gravel that holds the filter in place while allowing water to flow out of the sand boil. Such filters prevent sand boils from growing while relieving the underground hydrostatic pressure that created the sand boil in the first place and inhibiting subterranean erosion that can cause failure of a nearby levee. The conical shape provides relatively large surface area that inhibits clogging and allows each filter to be used for a range of different sand-boil sizes.

  • Patent number: 10502537
    Abstract: An ammunition round comprises an optimized projectile incorporating a hardened penetrator and an explosive self-destruct mechanism for a medium caliber high rate of fire round. The ammunition round incorporates a hardened segment penetrator followed by a pyrotechnically initiated high explosive warhead that substantially increases the effective range and terminal performance against RAM targets. The hardened segment penetrator localizes the kinetic energy of the projectile to increase target penetration prior to the initiation of the high explosive warhead.

  • Patent number: 10494272
    Abstract: The present invention is a self-regenerating biofilter. The biofilter tank receives untreated water through an intake inlet, filters it through a filtration mass and expels purified water through an output outlet. The filtration mass includes gravel and activated carbon layers separated by a mesh screen. A compressed air line is located below the mesh screen. Periodically, the biofilter self-cleans by opening a flush valve that expels a flush water stream carrying debris. The biofilter self-regenerates by periodically stopping filtration for a time, allowing biological matter left on the activated carbon to degrade into biomass. Periodically, the biofilter removes and flushes out biomass by application of water or a combination of air and water.

  • Patent number: 10495592
    Abstract: Provided are processes for the sensitive detection of the presence of, absence of, and optionally the identity of, one or more chemical agents. The processes use the binding of chemical agents to a metal organic framework or metal oxide/hydroxide electrically connected to a pair of electrodes to detect low levels of chemical in a sample. By exposing the surface of the metal organic framework or the surface of the metal oxide/hydroxide to the chemicals and then measuring changes in impedance magnitude and/or phase shift through electrical impedance spectroscopy, the presence of a chemical agent is readily detected.

  • Patent number: 10473452
    Abstract: A phase-resolved heterodyne shearing interferometer has been developed for high-rate, whole field observations of transient surface motion. The sensor utilizes polarization multiplexing and multiple carrier frequencies to separate each segment of a shearing Mach-Zehnder interferometer. Post-processing routines have been developed to recombine the segments by extracting the scattered object phase from Doppler shifted intermediate carrier frequencies, providing quantitative relative phase changes and information to create variable shear, phase resolved shearographic fringe patterns without temporal or spatial phase shifting.

  • Patent number: 10468540
    Abstract: An AlSb lattice matched barrier infrared detector architecture with the AlSb binary barrier layer enables implementation of strain layer superlattice absorbers with higher absorption coefficients for improved quantum efficiency, presents a simplified structure for epitaxial growth, and enables the utilization of bulk InAs0.815Sb0.185 absorber material with a 5.0 ?m cutoff for both single and dual color devices. Such an infrared detector is formed by growing the detector material; bottom contact, 1st absorber layer, AlSb barrier, optional graded layer, 2nd absorber layer, top contact, on top of an AlSb lattice matched buffer layer. Epitaxial growth on the AlSb lattice enables the deposition of unstrained bulk InAs0.815Sb0.185 with a 5.0 ?m cutoff, as well as InAs/InAs(x)Sb(1-x) superlattice absorbers with a continuously tunable cutoff from mid-wavelength to long-wavelength infrared.
