  • Patent number: 9470762
    Abstract: A novel method for real-time small-signal stability analysis for power electronic-based components in a power system. The method may be used to monitor a power system in real-time by perturbing the source side of an electronic-based component of the power system using a shunt current injection of about 0.5 to 1 percent of a nominal current of the power system at the source side, and perturbing the load side of the power electronic-based component by varying the voltage at the load side. Time-domain results of the perturbations may be transferred to frequency-domain results and the stability of the power system may be monitored by obtaining a Nyquist contour and employing Generalized Nyquist Criterion or unit circle criterion.

  • Patent number: 9469626
    Abstract: The invention provides new methods for the direct umpolung self-condensation of 5-hydroxymethylfurfural (HMF) by organocatalysis, thereby upgrading the readily available substrate into 5,5?-di(hydroxymethyl)furoin (DHMF). While many efficient catalyst systems have been developed for conversion of plant biomass resources into HMF, the invention now provides methods to convert such nonfood biomass directly into DHMF by a simple process as described herein. The invention also provides highly effective new methods for upgrading other biomass furaldehydes and related compound to liquid fuels. The methods include the organocatalytic self-condensation (umpolung) of biomass furaldehydes into (C8-C12)furoin intermediates, followed by hydrogenation, etherification or esterification into oxygenated biodiesel, or hydrodeoxygenation by metal-acid tandem catalysis into premium hydrocarbon fuels.

  • Publication number: 20160297689
    Abstract: An apparatus may include a separator and/or a discharger. A separator may include a separator channel, an influent portion configured to allow the passage of a first fluid into a separator channel, an effluent portion disposed above an influent portion and/or a fluid-lift portion between an influent portion and an effluent portion. A discharger may be disposed below a fluid-lift portion and/or may include a portion external to a separator channel, which may include a downward angle relative to an effluent portion and/or may be configured to minimize the passage of a second fluid into a discharger as the second fluid buoyantly travels in a separator channel from an influent portion to an effluent portion. A second fluid may have a density that is less than the density of a first and/or may be configured to lift a first fluid to a fluid-lift portion.

  • Publication number: 20160296319
    Abstract: An improved device provides a cost-effective, time-effective way to stably and reliably affix soft tissues (e.g., tendon or ligament) to the surface of anatomical structures with comparable or greater strength and stiffness (e.g., bone). The device does not require specialized procedures or tools. A single device applies both incremental tensioning and compression to the soft tissue being affixed. The device allows the user, typically a physician or veterinarian, to reliably manipulate, control, and maintain tissue tension. The device is versatile, and can accommodate attachment of soft tissues of different sizes and mechanical properties to bone or to other soft tissues. These features provide flexibility to human and veterinary health practitioners in a variety of specialized areas including orthopedics, joint stabilization, soft tissue repair, spinal surgery, and plastic surgery.

  • Patent number: 9465024
    Abstract: A method to measure all relevant biologic hydrogen sulfide pools, namely free hydrogen sulfide, acid-labile sulfide, and bound sulfane sulfur, has been developed. This new method involves selective liberation, trapping and derivatization of labile hydrogen sulfide. The total labile sulfide, including the contribution of the bound sulfane sulfur pool, the acid-labile pool, and free H2S, was measured by incubating the sample with a reducing agent, TCEP (Tris(2-carboxyethyl)phosphine hydrochloride), to reduce disulfide bonds in an acid solution. This method was used to measure the three sulfide pools in blood samples from mice and from humans. This method can be used for research, environmental, and clinical diagnostic purposes in determining hydrogen sulfide bioavailability in biological or other samples.

  • Patent number: 9467144
    Abstract: This disclosure relates generally to radiation hardened digital circuits. In one embodiment, a radiation hardened digital circuit includes a delay network and a first Muller C element. The delay network is configured to generate a first delayed clock signal from a global clock signal such that that the first delayed clock signal is delayed with respect to the global clock signal. The first Muller C element is configured to generate a first clock input signal and set the first clock input signal to one of a set of clock states in response to the first delayed clock signal and the global clock signal each being provided in a same one of the set of clock states and is configured to hold the first clock input signal otherwise. Thus, a radiation strike is prevented from causing a soft error in the first clock input signal.

  • Patent number: 9465106
    Abstract: Embodiments of the invention are directed toward attenuation correction of radar data. Atmospheric attenuation is a function of atmospheric water drop size and temperature. A number of different theoretical models are available to mathematically describe the particle drop shape that influences attenuation estimation. Each of these models has proven effective in different scenarios. It can be difficult, however, to predict which theoretical model to use. The total differential phase gives an idea of the attenuation, but it depends on the model. Moreover, the total attenuation along a rain path must be apportioned to different parts of the radar path in order to correct for attenuation along a radar path. Embodiments of this invention allows for a system to apportion the attenuation to different parts of the radar beam. Embodiments of the invention also allow for optimization of a number of different theoretical models for both drop size and temperature.

  • Patent number: 9466362
    Abstract: This disclosure relates generally to resistive memory systems. The resistive memory systems may be utilized to implement neuro-inspired learning algorithms with full parallelism. In one embodiment, a resistive memory system includes a cross point resistive network and switchable paths. The cross point resistive network includes variable resistive elements and conductive lines. The conductive lines are coupled to the variable resistive elements such that the conductive lines and the variable resistive elements form the cross point resistive network. The switchable paths are connected to the conductive lines so that the switchable paths are operable to selectively interconnect groups of the conductive lines such that subsets of the variable resistive elements each provide a combined variable conductance. With multiple resistive elements in the subsets, process variations in the conductances of the resistive elements average out.

  • Publication number: 20160294789
    Abstract: For multi-node encryption, a method communicates communication data from a first upstream node to a first downstream node in response to the first upstream node initiating secure communication with the first downstream node. The method further generates a downstream node nonce from communication data exchanged with the first downstream node. The method generates a first downstream message transformation as a function of the downstream node nonce. The method receives a request encrypted with the first downstream message transformation through the first downstream node. The method communicates the upstream message transformation encrypted with the first downstream message transformation through the first downstream node to the destination node in response to the request. In addition, the method generates a tunnel transformation at the destination node as a function of one or more upstream message transformations and the first downstream message transformation.
