  • Patent number: 10027698
    Abstract: A method and apparatus for managing an attack on a computer system. A computer identifies actions taken by an adversary in the computer system and links connecting the actions over time using an ontology defining linking rules for linking the actions over time. The computer creates a graph of the actions with the links connecting the actions over time. The graph shows a number of patterns of behavior for the adversary. The computer then identifies a protective action to take with respect to the computer system using the graph of the actions taken by the adversary.

  • Patent number: 10025123
    Abstract: The various technologies presented herein relate to various hybrid phononic-photonic waveguide structures that can exhibit nonlinear behavior associated with traveling-wave forward stimulated Brillouin scattering (forward-SBS). The various structures can simultaneously guide photons and phonons in a suspended membrane. By utilizing a suspended membrane, a substrate pathway can be eliminated for loss of phonons that suppresses SBS in conventional silicon-on-insulator (SOI) waveguides. Consequently, forward-SBS nonlinear susceptibilities are achievable at about 3000 times greater than achievable with a conventional waveguide system. Owing to the strong phonon-photon coupling achievable with the various embodiments, potential application for the various embodiments presented herein cover a range of radiofrequency (RF) and photonic signal processing applications. Further, the various embodiments presented herein are applicable to applications operating over a wide bandwidth, e.g. 100 MHz to 50 GHz or more.

  • Patent number: 10024983
    Abstract: Exemplary embodiments of several new metal-loaded plastic scintillators are reported herein, comprising sterically and electronically isolated organotin additive complexes. Distance-dependent quenching relationships have been used as design criteria for the selection and synthesis of these organometallic additives, resulting in increased light yields and improved gamma-ray energy resolution values relative to previously reported PS/PVT examples. Fast scintillation decay properties have also been characterized in the prepared scintillators, rivaling the kinetics of stilbene-doped bibenzyl and BC-422Q-1% while providing higher light yields than these reference materials.

  • Patent number: 10026701
    Abstract: The various technologies presented herein relate to isolating an integrated circuit from electromagnetic radiation/interference. The integrated circuit can be encapsulated in a coating (e.g., a conformal coating). A conductive layer can be formed over the coating, where the conductive layer is deposited to connect with an electromagnetic shielding layer included in a substrate upon which the integrated circuit is located thereby forming a Faraday cage around the integrated circuit. Hollow spheres can be included in the coating to improve the dielectric constant of the coating. The conductive layer can be formed from at least one of metallic material or a polymer coating which includes conductive material. The integrated circuit can be utilized in conjunction with a heat sink and further, the integrated circuit can be of a flip chip configuration.

  • Patent number: 10020968
    Abstract: Described herein are various technologies relating to processing a coherent signal. A receiver is configured to receive an analog signal, and process the analog signal to generate an input analog signal. The input analog signal has been modulated according to a suitable modulation sequence. A coherent signal sampler coherently samples the modulation sequence, and the result of such sampling is in turn used to demodulate the input analog signal. The resultant signal is then passed to a sigma delta modulator, where it is converted to digital form.

  • Patent number: 10018718
    Abstract: The various technologies presented herein relate to reducing and/or filtering undesired artifacts in a SAR image, wherein the artifacts are generated by RF interference resulting from a communication signal being included in a radar return which also comprises radar clutter. The radar return is separated into two subapertures, a first subaperture comprising radar clutter only, and a second subaperture comprising radar clutter and the communication signal. The communication signal is extracted from the second subaperture and reapplied to the initially received radar return. Reapplication of the communication signal to the radar return enables any undesired artifacts arising from the communication signal to have their return strength reduced or minimized, while maintaining any desired radar returns in the SAR image.

  • Patent number: 10000377
    Abstract: Nanostructured metal amides and nitrides are incorporated into nanoporous templates, such as carbon, using liquid ammonia as a solvent/reagent. This leads to unexpected improvements in metal amide nanoconfined hydrogen storage materials. The resulting nanostructured materials may reversibly absorb and desorb large capacities of hydrogen under conditions that are much milder compared to what has been achieved with bulk materials. In addition, the nanoconfined materials may reduce the amounts of ammonia released upon dehydriding, which may make the released hydrogen gas purer and may limit the capacity loss. In addition, nanoconfinement may simplify the reaction mechanism, eliminating undesired metal imide intermediates and promote hydrogen cycling under mild conditions. The liquid ammonia method also allows the simultaneous introduction of catalytic additives along with the parent hydrogen storage material.

  • Patent number: 9992219
    Abstract: The various technologies presented herein relate to pertaining to identifying and mitigating risks and attacks on a supply chain. A computer-implemented representation of a supply chain is generated comprising nodes (locations) and edges (objects, information). Risk to attack and different attack vectors can be defined for the various nodes and edges, and further, based upon the risks and attacks, (difficulty, consequence) pairs can be determined. One or more mitigations can be generated to increase a difficulty of attack and/or reduce consequence of an attack. The one or more mitigations can be constrained, e.g., by cost, time, etc., to facilitate determination of how feasible a respective mitigation is to implement with regard to finances available, duration to implement, etc. A context-free grammar can be utilized to identify one or more attacks in the supply chain. Further, the risks can undergo a ranking to enable mitigation priority to be determined.

  • Patent number: 9987605
    Abstract: Continuous, three-dimensional control of the vorticity vector is possible by progressively transitioning the field symmetry by applying or removing a dc bias along one of the principal axes of mutually orthogonal alternating fields. By exploiting this transition, the vorticity vector can be oriented in a wide range of directions that comprise all three spatial dimensions. Detuning one or more field components to create phase modulation causes the vorticity vector to trace out complex orbits of a wide variety, creating very robust multiaxial stirring. This multiaxial, non-contact stirring is particularly attractive for applications where the fluid volume has complex boundaries, or is congested.
