  • Multiscale deformation measurements leveraging tailorable and multispectral speckle patterns
    Patent number: 10845187
    Abstract: Remote measurements using images are particularly useful in structural health monitoring cases in which the installation of contact sensors is difficult. Some limitations, though, associated with photogrammetry-type optical metrology involve the application of speckle patterns, which become even more important with variable working distance or when the required resolution and sensitivity are not a priori known. In this context, multispectral sensing combined with tailored speckle patterns can circumvent some of the challenges of acquiring data at different working distances. The present invention uses multispectral imaging combined controlled generation of speckle patterns to demonstrate an approach for remote sensing related to deformation measurements at the structural level. To demonstrate this approach, two speckle patterns were designed for measurements at specified working distances.

  • SECURING ANALOG MIXED-SIGNAL INTEGRATED CIRCUITS THROUGH SHARED DEPENDENCIES
    Publication number: 20200342142
    Abstract: The transition to a horizontal integrated circuit (IC) design flow has raised concerns regarding the security and protection of IC intellectual property (IP). Obfuscation of an IC has been explored as a potential methodology to protect IP in both the digital and analog domains in isolation. However, novel methods are required for analog mixed-signal circuits that both enhance the current disjoint implementations of analog and digital security measures and prevent an independent adversarial attack of each domain. A methodology generates functional and behavioral dependencies between the analog and digital domains that results in an increase in the adversarial key search space. The dependencies between the analog and digital keys result in a 3× increase in the number of iterations required to complete the SAT attack.

  • TRANSISTOR SIZING FOR PARAMETER OBFUSCATION OF ANALOG CIRCUITS
    Publication number: 20200250365
    Abstract: An approach is described for enhancing the security of analog circuits using Satisfiability Modulo Theory (SMT) based design space exploration. The technique takes as inputs generic circuit equations and performance constraints and, by exhaustively exploring the design space, outputs transistor sizes that satisfy the given constraints. The analog satisfiability (aSAT) methodology is applied to parameter biasing obfuscation, where the width of a transistor is obfuscated to mask circuit properties, while also limiting the number of keys that produce the target performance requirements.

  • Adaptive pursuit learning method to mitigate small-cell interference through directionality
    Patent number: 10694526
    Abstract: A learning protocol for distributed antenna state selection in directional cognitive small-cell networks is described. Antenna state selection is formulated as a nonstationary multi-armed bandit problem and an effective solution is provided based on the adaptive pursuit method from reinforcement learning. A cognitive small cell testbed, called WARP-TDMAC, provides a useful software-defined radio package to explore the usefulness of compact, electronically reconfigurable antennas in dense small-cell configurations. A practical implementation of the adaptive pursuit method provides a robust distributed antenna state selection protocol for cognitive small-cell networks. Test results confirm that directionality provides significant advantages over omnidirectional transmission which suffers high throughput reduction and complete link outages at above-average jamming or cross-link interference power.
