  • Patent number: 10724831
    Abstract: A system and process for interfering with the flight of one or more unmanned aerial vehicles (UAVs) includes aiming a deployment device in a direction of the one or more UAVs and deploying by the deployment device a package in the direction of the one or more UAVs. The package includes a fiber material consisting of multiple individual fibers formed of one or more biodegradable materials. When the fiber material is released from the package after deployment, it forms a cloud of multiple individual fibers and the cloud of multiple individual fibers physically interferes with a propeller system of the one or more UAVs, thus causing the one or more UAVs to lose the ability to remain aloft.

  • Patent number: 10662457
    Abstract: A portable fluidic platform for rapid and flexible end-to-end production of recombinant protein biologics includes a bioreactor system hosting stable and robust cell-free translation systems that is fluidically integrated with modular protein separation functionalities (e.g., size exclusion, ion exchange or affinity chromatography systems) for purification of the cell-free expressed product and which are configurable for process-specific isolation of different proteins, as well as for formulation. The bioreactor utilizes lysates from engineered eukaryotic (e.g., yeast) or prokaryotic (e.g., bacterial) strains that contain factors for protein folding and posttranslational modifications. Combination of various purification modules on the same fluidic platform allows flexibility of re-routing for purification of different proteins depending on specific target requirements.

  • Patent number: 10661261
    Abstract: Mixed-phase TiO2 nanofibers prepared via a sol-gel technique followed by electrospinning and calcination are provided as photocatalysts. The calcination temperature is adjusted to control the rutile phase fraction in TiO2 nanofibers relative to the anatase phase. Post-calcined TiO2 nanofibers composed of 38 wt % rutile and 62 wt % anatase exhibited the highest initial rate constant of UV photocatalysis. This can be attributed to the combined influences of the fibers' specific surface areas and their phase compositions.

  • Patent number: 10648863
    Abstract: A system and process scans a target area at a distance of 3-30 m for one or more materials. Scanning is performed by a coherent transmit beam aimed with the help of a thermal camera. The active source of the beam is a supercontinuum (SC) laser. The transmitted source beam is modulated by a high-speed Fourier-transform spectrometer prior to interaction with the target. Target reflected source beam is detected by an infrared detector, along with a reference portion of the transmitted source beam, as a series of interferograms; passed through a digitizer for digitizing the interferograms; and processed to producing spectrograms, wherein the spectrograms are indicative of one or more materials on the target.

  • Publication number: 20200092620
    Abstract: A system for collecting data from multiple sensors at a central node is described. The system includes multiple pairs of sensor array multiplexers (SAMs) and sensors connected in series along the length of two cables each having a twisted wire pair. A first end of the length of the two cables is connected to the central node for receiving data from each of the multiple pairs. The multiple pairs include sensors of at least two different types, which may have different sampling rates. The first cable carries timing data between the multiple pairs and the central node and the second cable carries sensor data between the multiple pairs and the central node.

  • Publication number: 20200064282
    Abstract: A scan head design uses 1:1 (one-to-one) imaging micro-lens arrays to transfer the object plane X-ray image from a CR-plate onto a linear photosensor. The scan-head includes a housing having therein, an array of red light emitting diodes (LEDs), a red-absorbing filter, a microlens array, an infrared-filter, and a sensor. The housing faces the CR-plate and the scan-head is translated across the CR-plate to read out the X-ray image therein. The scan head is compact and provides for improved spatial resolution and reduced power requirements.

  • Patent number: 10568002
    Abstract: A process for selecting an optimal individual user solution including an optimal rate allocation and associated price for a predetermined bandwidth of cellular network resources includes application of an iterative process and selection from multiple proposed user solutions. The inputs to the iterative process include at least an initial user bid, an initial network rate allocation, a generated user utility function and the cost data. The user utility function includes multiple application user functions. Optimal solution selection includes comparing each multiple proposed user rate allocation with the initial network rate allocation for the user and selecting the closest multiple proposed user rate allocation to the initial network rate allocation. The process may be applied to aggregated cellular carrier scenarios.

  • Patent number: 10331156
    Abstract: A system and method for learning and asserting what portions of a utility GIS network model are incorrect or flawed as they relate to real world conditions, and what the correct real world relationships are in the field is described. The system and method leverage available smart grid data to assess the quality of a primary (GIS) source data set; quality data renders derived analyzes across the utility valid, sound, and action worthy. The system and method utilize existing partially correct electrical network distribution model data and various non-specialized source data including smart meter, spatial, and customer information data collected from the network to test, validate and suggest corrections to the connectivity model. By forming putative ground truth assignments between utility components, the system tests the assumptions by examining the geospatial proximity and correlating voltage and event data over time to form refined hypothesis.

  • Patent number: 10318734
    Abstract: Data can be scanned using a network managed appliance. The network managed appliance may integrate commercial hardware elements connected through a basic or simplified operating system environment expressly developed for the appliance, thus being more malware resistant and less vulnerable to attacks from the scanned data or other sources. The network managed appliance may be a self-contained apparatus with an integrated chassis, designed and configured as “single-purpose” device. Such appliances may be connected to an appliance management network including central management servers in communication with appliances in remote locations. The central management servers may ensure that scanning software and the definitions lists for each of the appliances are current and match an enterprise-approved configuration. In addition, an antivirus appliance may facilitate creation and management of user rights assignments for those files.
