摘要： A supercritical water oxidation-flame piloted vortex reactor has a hydrothermal flame produced within the interior of the reactor fed by a fuel including a waste water stream, and has a subcritical wash stream, including water below its critical point, that creates an upward helical flow in the material within the reactor. The hydrothermal flame and upward helical flow produce within the reactor a supercritical core region, a subcritical outer region around the core region, and a transcritical intermediate region between them. The upward helical flow serves to transfer precipitated ionic compounds out of the supercritical core region, through the transcritical intermediate region, and into the subcritical outer region where they re-dissolve. A processed flow, including purified water, is removed from an upper portion of the supercritical core region by an aspirator.

摘要： Systems, methods, and devices of the various embodiments provide for the creation of holey graphene meshes (HGMs) and composite articles including HGMs. Various embodiments provide solvent-free methods for creating arrays of holes on holey graphene-based articles formed from dry compression (such as films, discs, pellets), thereby resulting in a HGM. In further embodiments, a HGM can used as part of a composite, such as by: 1) embedding a HGM into another matrix material such as carbon, polymer, metals, metal oxides, etc; and/or (2) the HGM serving as a matrix by filling the holes of the HGM or functionalizing the HGM body with another one or more materials. In various embodiments, HGM can also be made as a composite itself by creating holes on dry-compressed articles pre-embedded with one or more other materials.

摘要： One aspect of the present disclosure is an imaging system including an optical sensor defining an optical axis. The system further includes a light source. The system may include an optical beam splitter, and may also include an optional diffusing lens that may be configured to diffuse and/or collimate light from the light source and direct light exiting the diffusing lens to the optical beam splitter. The optical beam splitter is configured to direct light from the light source along the optical axis of the optical sensor.

摘要： A wireless flight sensor system that incorporates a network of wireless sensors all in communication with a sensor gateway, the gateway in turn being in communication with a flight network. The sensor gateway includes a software defined radio (SDR) by which sensors communicate. The SDR is easily reconfigurable to accommodate new wireless technology. The flight network software (FNS) comprises a modular software architecture with a management repository, a traffic manager, a wireless interface controller, and a sensor database. The resulting system is both scalable and easily reprogrammable to accommodate a wide variety of current and future wireless sensing capability.

摘要： A fully automated fabrication method and system utilizing a single additive manufacturing platform to fabricate solar cell panels without human-touch labor. The system includes a computer and a robotic arm having a machine vision device and a tool changer to which tools are releasably secured. In an exemplary embodiment, the fabrication method uses pre-fabricated substrates wherein the computer controls the robotic arm to deposit an adhesive layer on a pre-fabricated substrate and thereafter place solar cells on the adhesive layer. The solar cells become bonded to the substrate when the adhesive layer cures. The computer then controls the robotic arm to print electrical connections and electrical bus bars on the substrate with electrically conductive ink in order to electrically connect the solar cells. After the electrically conductive ink cures, the computer controls the robotic arm to spray an encapsulating material over the solar cells and substrate.

摘要： An apparatus for remote support of autonomous operation of a vehicle includes a processor that is configured to perform a method including receiving, from a vehicle traversing a driving route from a start point to an end point at a destination, an assistance request signal identifying an inability of the vehicle at the destination to reach the end point, generating a first map display including a representation of a geographical area and the vehicle within the geographical area, receiving, from the vehicle, sensor data from one or more sensing devices of the vehicle, generating a remote support interface including the first map display and the sensor data, and transmitting instruction data to the vehicle that includes an alternative end point at the destination responsive to an input signal provided to the remote support interface.

摘要： The present invention relates to a novel, non-rotating tomographic imaging system, including a multi-source x-ray imaging module which includes multiple x-ray sources within a vacuum manifold, each equipped with a non-thermionic cathode which can reduce image scan time (and hence, motion artifacts), or delivered radiation dose, through under-sampled acquisition sequences, and without adding additional sources. The non-thermionic nature of the cathode enables rapid on/off switching of x-rays without concern as to the thermal mass or the thermal time-constant of the cathode. The modules can be flexibly interconnected to each other to allow configuration as part of a distributed ring of sources, or in other x-ray imaging geometries. Modularity provides the present invention an advantage in making it easier to debug and repair a distributed-source imaging system, such as a computed tomographic (CT) system.

摘要： The present invention relates to a novel method and system for crater detection in planetary data based on marked point processes (MPP), effective for various object detection tasks in Earth observation, and for planetary image registration. The resulting spatial features are exploited for registration, together with fitness functions based on the MPP energy, on the mean directed Hausdorff distance, and on the mutual information. Two different methods—one based on birth-death processes and region-of-interest analysis, and the other based on graph cuts and decimated wavelets—are included within the present framework. Experimental results confirmed the effectiveness of the present invention in terms of crater detection performance and sub-pixel registration accuracy.

摘要： This system combines 3D printing technology with artificially modified cells for production of nonliving biomaterials. A 3D printer deposits a 3D array of bioengineered cells in the shape of a selected product. The cells are programmed to produce biomaterials in regulated amounts. The cell array deposits biomaterials onto a substrate. The cells and substrate are then removed, leaving a finished, nonliving product with microscale structure and precision.

摘要： A method for recognizing infrasound events includes detecting infrasonic source using one or more microphone arrays each having three equally-spaced infrasound microphones. The method includes identifying, via a data acquisition system (DAS), a level of coherence of the detected infrasonic acoustic signals from each possible pair of microphones and recognizing the infrasound source using the coherence and a time history of the detected signals. The method may include estimating source properties via the DAS, including a magnitude, azimuth angle, and elevation angle, and executing a control action in response to the estimated properties. A system includes the array and the DAS. The array may be positioned above or below ground, and may be connected to one or more aircraft in some embodiments.
