  • Patent number: 9507993
    Abstract: A contactless, three-dimensional fingerprint scanner apparatus, method, and system are described. The contactless fingerprint scanner can provide either, or both, topographical contrast of three-dimensional fingerprint features and optical contrast of a three-dimensional fingerprint surface. Data captured from scanning of a target with known geometric features mimicking fingerprint features can be examined as images or surface plots and analyzed for fidelity against the known target feature specifications to evaluate or validate device capture performance as well as interoperability. The target can be used by scanner vendors and designers to validate their devices, as well as to perform type certification.

  • Patent number: 9500610
    Abstract: Systems and methods for controlling the temperature of small volumes such as yoctoliter volumes, are described. The systems include one or more plasmonic nanostructures attached at or near a nanopore. Upon excitation of the plasmonic nanostructures, such as for example by exposure to laser light, the nanoparticles are rapidly heated thereby causing a change in the ionic conductance along the nanopore. The temperature change is determined from the ionic conductance. These temperature changes can be used to control rapid thermodynamic changes in molecular analytes as they interact with the nanopore.

  • Patent number: 9450673
    Abstract: A microwave-frequency source at frequency fM comprises: a dual optical-frequency reference source, an electro-optic sideband generator, an optical bandpass filter, an optical detector, a reference oscillator, an electrical circuit, and a voltage-controlled oscillator (VCO). The sideband generator modulates dual optical reference signals at v2 and v1 to generate sideband signals at v1±n1fM and v2±n2fM. The bandpass filter transmits sideband signals at v1+N1fM and v2?N2fM. The optical detector generates a beat note at (v2?N2fM)?(v1+N1fM). The beat note and a reference oscillator signal are processed by the circuit to generate a loop-filtered error signal to input to the VCO. Output of the VCO at fM drives the sideband generator and forms the microwave-frequency output signal. The resultant frequency division results in reduced phase noise on the microwave-frequency signal.

  • Patent number: 9437923
    Abstract: A system and method for imaging and aligning antennas that includes an overlay imaging aligner composed of two or more antennas in association with a polarization gate, a polarization beam splitter, a non-polarizing beam splitter, a beam dump, one or more imaging lens and a common detector array. The overlay imaging aligner aligns the antennas by overlaying simultaneous digital images associated with the antennas on the common detector array. The antennas can be, for example, mm Wave antennas, waveguides, etc. The detector array generates real-time digital images the antennas. Such an approach of simultaneous imaging leverages the spatial resolution of digital optical imaging to aligning antenna components.

  • Patent number: 9341781
    Abstract: An apparatus and technique are used to fabricate optical microresonators. A fabrication chamber contains all fabrication materials and devices. The microresonators are fabricated from a glass preform mounted on a motorized spindle. A laser is focused onto the preform to partly or fully impinge on the preform. The laser's focus position is controlled by changing the positioning of a lens mounted on a translation stage. Piezoelectric control elements may be mounted to finished microresonators to control of nonlinear parametric oscillation and four-wave mixing effects of the microresonator, control of nonlinear optical stimulated Brillouin scattering and Raman effects of said microresonator and wideband tuning of the frequency spacing between the output modes of a nonlinear-Kerr-effect optical frequency comb generated with said microresonator.

  • Patent number: 9325729
    Abstract: Systems and methods for determining a safety level of a network vulnerable to attack from at least one origin to at least one target are described. Machines, components, and vulnerabilities in a network may be associated to one another. Degrees of similarity among the vulnerabilities may be determined and subsets of vulnerabilities may be grouped based on their determined degrees of similarity to one another. This data may be used to generate an attack graph describing exploitation of vulnerabilities and grouped vulnerabilities and defining vulnerability exploit condition relationships between at least one origin and at least one target. The attack graph may be analyzed using a k-zero day metric function to determine a safety level.
