  • Patent number: 9998487
    Abstract: A normal space data source stores, for each of a plurality of threat nodes, a series of normal values that represent normal operation of an industrial asset control system, and a threatened space data source stores a series of threatened values. A model creation computer may generate sets of normal and threatened feature vectors. The computer may also calculate and output at least one decision boundary for a threat detection model based on the normal and threatened feature vectors. The plurality of threat nodes may then generate a series of current values from threat nodes that represent a current operation of the asset control system. A threat detection computer may receive the series of current values from threat nodes, generate a set of current feature vectors, execute the threat detection model, and transmit a threat alert signal based on the current feature vectors and at the least one decision boundary.

  • Patent number: 9994470
    Abstract: Recalcitrant chemical oxygen demand (COD) of a liquid is reduced in a water treatment system. The method includes pretreating the liquid in a pretreatment unit to remove indigenous bacteria or microbes to a population level below which the indigenous organisms can interfere with the screened and externally introduced microorganisms. The liquid is then provided to a reactor that has a filter bed formed with a carrier material. Special microbes are screened and used to colonize the carrier material to remove recalcitrant COD. A biofilm is cultured on the surface of the carrier material to immobilize the screened microbes in the reactor. The method further includes percolating the liquid from the pretreatment unit through the filter bed colonized with the screened microbes to degrade at least part of the recalcitrant COD under aerobic conditions.

  • Patent number: 9998089
    Abstract: A resonator device 10 is disclosed. The resonator device may be used in a transducer or a sensor such as a pressure, force or acceleration sensor. The resonator device comprises a resonator 20 provided on a diaphragm 30. A cap 40 is provided which may be fusion bonded to the diaphragm 30 to enclose the resonator 20 and form a hermetically sealed package 10. The resonator device is excited by applying electromagnetic stimulation, such as infra-red or optical stimulation, which may be from a laser via a fiber 50. The resonator device may be interrogated by applying an electromagnetic signal into the optical cavity formed between the resonator 20 and the inside surface of the cap 40 to derive a frequency change of the resonator. As the resonator device incorporates a hermetically sealed package and is stimulated by electromagnetic radiation, it is robust and able to operate in harsh environments.

  • Patent number: 9996747
    Abstract: A ground based wind turbine blade inspection system and method consists of a thermal imaging camera configured to detect propagating defects by acquiring thermal imaging data from a wind turbine blade when it is substantially at thermal equilibrium with respect to surrounding air and analyzing the thermal imaging data with a processor to identify thermal effects associated with latent defects caused by internal friction due to cyclic gravitational stresses and wind loads during normal turbine operation. The system permits latent defects to be identified using a ground-based in situ inspection before they become visually apparent, which allows repairs to be made economically while the blade is in place.

  • Patent number: 9997317
    Abstract: A switching system includes a control circuit that receives On-Off signals indicative of a desired operating state of a switch. The control circuit includes an oscillator that generates a first electrical pulse responsive having a first signal characteristic or a second signal characteristic that is determined by the received On-Off signal, which may be related to a frequency or duty cycle of the pulse. A pulse transformer connected to the oscillator receives the first electrical pulse and outputs a second electrical pulse having the same one of the first signal characteristic and the second signal characteristic as the first electrical pulse. A pulse detection circuit in the control circuit receives the second electrical pulse, determines whether the second electrical pulse has the first signal characteristic or the second signal characteristic, and controls transmission of power and control signals to the switch based on this determination.

  • Patent number: 9997921
    Abstract: A solar power conversion system includes a photovoltaic array having photovoltaic modules for generating direct current (DC) power. A power converter in the system converts the DC power to alternating current (AC) power. The AC power is transmitted to the power grid via a transformer coupled between the power converter and the power grid. The transformer is connected to the power grid at the point of common coupling (PCC) and to the power converter at output terminals. A voltage estimation module is configured to estimate a voltage at PCC based on a measured voltage magnitude, a measured real power and a measured reactive power at the output terminals, and a reactance of the transformer. A controller is provided in the system for generating switching command signals for the power converter based on the voltage at PCC.
