  • Patent number: 10924382
    Abstract: Discussed herein is technology for verifiable network configuration repair. A method can include adding a routing adjacency or route redistribution edge to a router of an aETG to generate an enhanced aETG (eaETG), adding, for each dETG of dETGs, static route edges to a destination of the dETG to generate an enhanced dETG (edETG), determining, for each of the edETGs, all simple paths from all sources to the destination of the edETG, determining a set of paths (pathtset) over the determined simple paths that satisfies the policies, and translating the edge additions and/or removals in the eaETG and in the edETGs to an addition and/or removal of one or more of a routing adjacency, routing filter, or static route based on the determined pathset.

  • Patent number: 10853493
    Abstract: A system and method for detecting Trojans and other intermittent severe defects in a digital circuit design. A simulation of the digital circuit design results in a value change dump file, which is compiled to form a value change summary file containing counts of the numbers of value changes for the signals in the digital circuit design. A discriminative neural network analyzes the value change summary file to determine whether an intermittent severe defect is present. A corpus of digital circuit designs, with and without intermittent severe defects, is used to train the discriminative neural network. The training process may involve dimensionality reduction of the data, enlargement of the data set, and data compression using an autoencoder.

  • Patent number: 10467772
    Abstract: A system and method for determining positional order of vehicles across a threshold plane within a dynamic environment is provided. The system can include moving vehicles (e.g., boats) each having a GPS receiver. A reference object (e.g., an anchored boat) can have an image capturing device and a primary GPS receiver, and can be subject to movement induced by the dynamic environment. A fixed object having a known position (e.g., a government buoy) relative to the reference object define a threshold plane, which is subject to movement based on movement of the reference object. Photometric data gathered by the image capturing device and geospatial data gathered from the GPS receivers, the primary GPS receiver, and the fixed object is analyzed by a processor to determine a positional order at which each vehicle crossed the movable threshold plane.

  • Patent number: 10454016
    Abstract: A photon detector including a graphene-insulating-superconducting junction configured as a temperature sensor. Photons are absorbed by the graphene sheet of the graphene-insulating-superconducting junction, each absorbed photon causing a temporary increase in the temperature of the graphene sheet, and a corresponding change in the differential impedance of the graphene-insulating-superconducting junction. The graphene-insulating-superconducting junction is part of a resonant circuit connected as a shunt load between a radio frequency input transmission line and a radio frequency output transmission line. The transmission S-parameter from input to output is affected by the impedance of the resonant circuit which in turn is affected by the differential impedance of the graphene-insulating-superconducting junction, and therefore by the temperature of the graphene sheet.

  • Patent number: 10361860
    Abstract: A system for authentication and validation of the identity of a person. The person carries a mobile device configured to measure motion as the person walks or stands still, generating a time record of motion data. A security system in a facility which the person seeks to access receives the time record of motion data and compares gait characteristics inferred from the time record with gait characteristics inferred from motion data previously obtained for a person whom the person seeking access purports to be. The security system may instruct the person to pause and stand still, and then to begin walking again, and it may then verify that the received time record of motion data includes an interval with little motion at a point in the time record corresponding to the pause.
