  • 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.

  • Patent number: 10353060
    Abstract: A system for isolating signals from individual vehicles. An array of sensors generates a plurality of time records. The time records are transformed into spectrogram structures, and for each time-frequency point in the spectrogram structures, a bearing is calculated, to form a movement structure. A Hough transform is used to fit a movement model to the movement structure, to form a Hough transform structure. Peaks in the Hough transform structure correspond to vehicles and their position in the Hough transform structure correspond to motion parameters, such as the velocity of the vehicle, and the time of closest approach of the vehicle to the array of acoustic sensors. A model of the motion of a vehicle is then used to associate, with the vehicle, points (e.g., structure elements in the spectrogram structures) from the data.

  • Patent number: 10295593
    Abstract: Embodiments includes an apparatus and method that intentionally illuminate a device with RF energy having specific characteristics (e.g., frequency, power, waveform, directionality, duration, etc.) to make a conductor of the device a transmitter. A method can include identifying data to be transmitted by the one or more conductors and providing a signal to the electrical or electronic circuitry to cause the electrical or electronic circuitry to change state and produce a first signal on the one or more conductors. The one or more conductors can produce a forced non-linear emission (FNLE) that is a mixture of the first signal and an electromagnetic wave incident thereon that, when decoded by an external device, corresponds to the data.

  • Patent number: 10291274
    Abstract: An apparatus and method that intentionally illuminate a number of target devices with RF energy having specific characteristics (e.g., frequency, power, waveform, directionality, duration, etc.) are provided. The target devices, which may comprise a computer system or other electronic circuits, by their fundamental nature as mixed analog and digital devices, act as non-linear mixers and are forced to emit information about the target device behavior, state, and physical characteristics. The apparatus that implements the method receives the forced emissions signals, extracts useful data from noise, and analyzes the data to determine target device characteristics. The target devices may be powered or unpowered. The apparatus and method provided may avoid impacting target device operation.

  • Patent number: 10272979
    Abstract: A subsea system for exploiting an oceanic current shear includes a first vehicle positionable in a first oceanic current and tethered to a second vehicle positionable in a second oceanic current. The first and second oceanic currents have a velocity differential. A drag or lift device integral or attached to the first vehicle exerts a force through the tether on the second vehicle and its associated drag or lift device, thus providing a net propulsive force. Hydrofoils or control devices attached to the vehicles provide hydrodynamic lift, drag, and/or depth control that allow the direction of the force to be controlled for propulsion in a desired direction. The relative currents and/or change in separation of the vehicles can be used for energy harvesting. Turbines and generators coupled to the vehicles harvest energy for long term subsea endurance. A sensor aperture comprises a plurality of sensors coupled to components of the subsea system.

  • Patent number: 10274587
    Abstract: A system for covert sensing. A broadband light source is split into two portions, a first portion of which illuminates a target, and a second portion of which is frequency shifted, e.g., by an acousto-optic frequency shifter. Light reflected from the target is combined with the frequency shifted light, detected, and demodulated with an in-phase and quadrature demodulator. The outputs of the demodulator are filtered and the arc tangent of the ratio is calculated.

  • Patent number: 10264440
    Abstract: An apparatus, method, and computer program product that intentionally illuminate at least one target device with electromagnetic energy having specific characteristics (e.g., frequency, power, waveform, directionality, duration, etc.). The target device, which may be an unpowered data storage device, acts as a non-linear mixer and is forced to emit radiative signals containing information about the target device behavior, state, and physical characteristics. Embodiments receive the forced emissions, extract useful data, and analyze the data to determine target device characteristics (e.g., a target device type, based on a comparison of data from known types). Embodiments control the illumination so the forced emissions radiate from an enclosure without interfering with tactical communications, and so that stored target device data is not affected. Embodiments can locate a hidden target device via the strength and directionality of the forced emissions.

  • Patent number: 10217920
    Abstract: A sensing system including in-ground sensors not requiring battery power. A thermoelectric generator sensor rod includes an upper thermal contact and a lower thermal contact at or near its two ends. When the thermoelectric generator sensor rod is buried in the ground with one end buried more deeply than the other, a temperature gradient in the soil produces a temperature difference between the upper thermal contact and the lower thermal contact. The upper thermal contact and the lower thermal contact are thermally connected to a thermoelectric generator, e.g., by heat pipes or thermally conductive rods. Electrical power generated by the thermoelectric generator powers sensors for monitoring conditions in the ground, and circuitry for transmitting sensor data to a central data processing system.
