  • Patent number: 11104620
    Abstract: A method for manufacturing nano-sized insensitive high explosive molding powder usable as a booster HE is provided herein. The method preferably involving the steps of dissolving a binder in a liquid and suspending crystalline high explosive to said liquid, grinding that suspension in a bead mill until the crystalline high explosive is nano-sized, and precipitating the binder and crystalline high explosive using a spray dryer to produce granules containing nano-sized crystalline high explosive. The liquid may be water or an organic solvent so long as the binder is highly soluble in the liquid and the crystalline high explosive is generally insoluble in the liquid. A fatty alcohol, water defoaming/dispersant/surfactant agent can be added to the dissolved binder/suspended crystalline high explosive, to aid in the manufacturability.

  • Patent number: 11103406
    Abstract: In one embodiment, a prefabricated container is modified as a medical isolation room by replacing an original door with a clear front door. An intake louver and an adjustable damper are disposed at a lower part of the front end. An exhaust vent is disposed at an upper part of the back wall. An exhaust fan and a HEPA filter are coupled to the exhaust vent. Washable coverings cover interior sides of the container to provide washable, nonslip interior surfaces. The exhaust fan and the adjustable damper at the intake louver are controlled to produce in the medical isolation room a negative air pressure of at least about minus 0.01 inch of water gage (approximately 2.5 pascals) and a displacement ventilation exhaust flow rate through the exhaust vent of at least about 100 cubic feet per minute (cfm) greater than an intake flow rate through the intake louver.

  • Patent number: 11080867
    Abstract: In one embodiment, an infrared camera generates thermal images and a computer generates track trees for volant targets (e.g., bats) detected in the images using an HKUF technique and detection filtering. The computer extends each track tree by adding new branches for each target detected in a subsequent image, generates motion metrics for each new branch, applies biologically informed motion constraints to the motion metrics to delete branches from the track trees, selects a track in each terminated track tree as a most likely track for the corresponding detected target using a track-scoring system based on a combination of track tortuosity and Kalman prediction errors, automatically generates a counting box based on density plots generated using the selected tracks, and calculates a census of the volant targets based on the selected tracks relative to the counting box. The technique handles targets that may be occluded for one or more images.

  • Patent number: 11081252
    Abstract: An electrophoretic deposition (EPD) process forms a radioluminescent phosphor and radioisotope composite layer on a conductive surface of a substrate. In the composite layer formed, the particles of radioisotope are homogeneously dispersed with the radioluminescent phosphor. The radioisotope may be a beta-emitter, such as Ni-63, H-3, Pm-147, or Sr-90/Y-90. By applying the composite layer using the EPD process, the electrode can be configured for betavoltaic, beta-photovoltaic and photovoltaic cells according to further embodiments. A direct bandgap semiconductor device can convert betas and/or photons emitted from composite layer. Methods and choice of materials and components produces a hybrid radioisotope battery, conversion of photons and nuclear decay products, or radioluminescent surfaces.

  • Patent number: 11073160
    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.

  • Patent number: 11062525
    Abstract: A method for generating an augmented set of images involves data collection, data processing, and data augmentation processing performed to merge images. The data collection comprises the steps of choosing objects as selected objects, choosing configurations for imaging of the selected objects, and taking pictures with a second camera to create a set of raw object images. The data processing comprises the steps of performing dynamic range adjustment on the raw object image, performing color correction for corrected images, and removing uniform background from the corrected images to result in object images. The data augmentation processing performed to merge images comprises the steps of performing range simulation or magnification for resampled images, adding blur to the resampled images, adding noise to create final object images, and merging the final object images to the field images of a first camera to create a set of augmented images.

  • Patent number: 11061083
