Publication number: 20200103175Abstract: A vapor-chamber that includes a porous microstructure sheet with varying surface energy across different regions to optimize utilization of a working fluid. Modulating the surface energy of the porous microstructure sheet can minimize the amount of the working fluid that becomes trapped in the condenser region(s) and maximize an aggregate thin-film evaporation area of the working fluid in the evaporator region(s). The condenser region of the vapor-chamber is treated so that the internal surfaces have low surface energy. For example, the treatment may cause the condenser region to become hydrophobic to minimize the amount of fluid that becomes trapped in the condenser. The evaporator region is treated so that the internal surfaces have high surface energy. For example, the treatment may cause the evaporator region to become hydrophilic to induce the formation of large numbers of robust (e.g., dry-out resistant) thin-film evaporation sites.Type: ApplicationFiled: March 13, 2019Publication date: April 2, 2020Inventors: Shahar BEN-MENAHEM, Tzu-Yuan LIN, Michael NIKKHOO

Publication number: 20200103204Abstract: A concealment substrate manufacturing process begins by printing or painting a graphic design as camouflage on substrates like mesh-textured uniforms, military equipment, Mylar thermal blanket sheets, adhesive tapes, etc. The graphic design is uniquely generated from pseudo-random noise in four overlaying color pigments that each begin as a raster of randomly generated noise in a standardized tile size. E.g., gray, green, tan, and brown colors natural for concealment applications are each masked by two-tone image contrast rasters. The four results are mixed together in groups with a monochrome mixing mask to produce a whole tile. Such concealment camouflage tile conjoins seamlessly on-edge within other arrays of identical tiles. One variation adds a distorted-grid mesh-texture overly texture to the concealment camouflage, and even a faint “watermark” related to a commercial trademark.Type: ApplicationFiled: August 8, 2019Publication date: April 2, 2020Inventors: Jarod Lee King, Richard Brewster Main

Publication number: 20200103209Abstract: The invention relates to a shell (4) intended to be placed around a fragment-generating body (2) of an ammunition (1). This shell is characterized in that it comprises an inner wall (9) having a geometry such that it can be positioned with shape matching with that of the body (2) on which it is intended to be fastened, the inner wall (9) bearing cells (11) having a profile with a closed contour secured to the wall (9) by a first end, the cells (11) not being adjoining, therefore separate from one another, all the way around their contour by a non-nil distance (d). The invention also relates to an explosive ammunition including such a shell.Type: ApplicationFiled: September 30, 2019Publication date: April 2, 2020Applicant: NEXTER MUNITIONSInventors: Rémi BOULANGER, Frédéric NOZERES

Publication number: 20200103210Abstract: An apparatus for processing incendiary capsules for the purpose of prescribed burning. The apparatus includes a reciprocating injector tube driven by a crankshaft and a reciprocating mechanical pump driven by a cam. In order to synchronize these reciprocating motions the crankshaft and cam are joined together as a single part. The incendiary spheres exit a hopper and line up in series in a tube which deposits them one by one into a nest. Each individual sphere is punctured in the nest by a needle then injected with reactant. Each sphere is then withdrawn from the nest and dropped through a discharge opening before the next incendiary in line is processed in the same manner.Type: ApplicationFiled: September 25, 2019Publication date: April 2, 2020Inventor: Frederick SPARLING

Publication number: 20200103211Abstract: A device for generating power in a gravity dropped munition. The device including: a drum; a cable wound around a drum; a generator for producing electrical energy; a spring configured to convert rotation of the drum to energy as the cable is unwound from the drum; and an intermediate member selectively engaging the drum to the generator; wherein the intermediate member is disengaged from the drum when the cable is being unwound from the drum and the intermediate member is engaged with the generator when the cable is released from the drum to produce power from the generator.Type: ApplicationFiled: November 25, 2019Publication date: April 2, 2020Applicant: Omnitek Partners LLCInventors: Jahangir S. Rastegar, Jacques Fischer

Publication number: 20200103213Abstract: An embodiment of the invention relates to a method for carrying out a time-resolved interferometric measurement comprising the steps of generating at least two coherent waves, overlapping said at least two coherent waves and producing an interference pattern, measuring the interference pattern for a given exposure time, thereby forming measured interference values, and analyzing the measured interference values and extracting amplitude and/or phase information from the measured interference values. In at least one time segment, hereinafter referred to as disturbed time segment, of the exposure time, the interference pattern is intentionally disturbed or destroyed such that the corresponding measured interference values describe a disturbed or destroyed interference pattern.Type: ApplicationFiled: February 27, 2018Publication date: April 2, 2020Applicant: Technische Universitaet BerlinInventors: Michael LEHMANN, Tore NIERMANN, Tolga WAGNER

Publication number: 20200103215Abstract: Apparatus and methods are presented for enhancing the acquisition speed or performance of Fourier domain optical coherence tomography. In preferred embodiments a plurality of wavelength combs containing interleaved selections of wavelengths from a multi-wavelength optical source are generated and projected onto a sample. In certain embodiments the wavelength combs are projected simultaneously onto a plurality of regions of the sample, while in other embodiments the wavelength combs are projected sequentially onto the sample. Light in the wavelength combs reflected or scattered from the sample is detected in a single frame of a sensor array, and the detected light processed to obtain a tomographic profile of the sample. In preferred embodiments the wavelength comb generator comprises a wavelength interleaver in the form of a retro-reflective prism array for imparting different displacements to different selections of wavelengths from the optical source.Type: ApplicationFiled: September 4, 2019Publication date: April 2, 2020Inventor: Steven James FRISKEN
