  • Patent number: 10033263
    Abstract: A system and a method for optimizing fundamental frequency modulation in a cascaded multilevel inverter (CMI) are provided. The CMI includes at least a first H-bridge module and a second H-bridge module connected in series with the first H-bridge module. The first H-bridge module is operated according to a first duty cycle and the second H-bridge module is operated according to a second duty cycle. The first duty cycle is greater than the second duty cycle. The first and second H-bridge modules are controlled utilizing fundamental frequency modulation. A portion of the first duty cycle is transferred to the second duty cycle thereby optimizing fundamental frequency modulation by at least improving power sharing between the first and second H-bridge modules and improving equalization of DC capacitor currents and voltage ripples while maintaining the same fundamental modulation to the output voltage waveform.

  • Patent number: 10004917
    Abstract: A neural prosthetic device can selectively deliver light to different cortical layers, at different depths, in the brain. The device includes LEDs and corresponding waveguides that can extend into the brain. At least two of the waveguides have different lengths. The neural prosthetic device or other devices can be manufactured by changing the hydrophilicity or lyophilicity of a portion of a substrate layer, then depositing uncured polymer on the treated portion of the substrate layer. The uncured polymer flows under the influence of surface tension to form a volume. The volume is shaped as a dome that extends laterally to a boundary between the treated and untreated portions. The polymer is cured in discrete regions through the substrate layer. The discrete regions extend longitudinally from the substrate layer to a curved surface of the dome. The uncured portion of the polymer is removed. The cured regions form the waveguides.

  • Publication number: 20180156902
    Abstract: Shear waves are generated and measured in viscoelastic phantoms by a single push beam. Using numerical simulations or an analytical function to describe the diffraction of the shear wave, the resulting shear wave motion induced by the applied push beam is calculated with different shear elasticity values and then convolved with a separate expression that describes the effects of viscosity value for the medium. The optimization algorithm chooses the tissue parameters which provide the smallest difference between the measured shear waveform and the simulated shear waveform. A shear viscosity image is generated by applying such optimization procedure at all of the observation points.

  • Patent number: 9951431
    Abstract: A process and related electrode composition are disclosed for the electrocatalytic hydrogenation and/or hydrodeoxygenation of organic substrates such as biomass-derived bio-oil components by the production of hydrogen atoms on a catalyst surface followed by the reaction of the hydrogen atoms with the organic reactants. Biomass fast pyrolysis-derived bio-oil is a liquid mixture containing hundreds of organic compounds with chemical functionalities that are corrosive to container materials and are prone to polymerization. A high surface area skeletal metal catalyst material such as Raney Nickel can be used as the cathode. Electrocatalytic hydrogenation and/or hydrodeoxygenation convert the organic substrates under mild conditions to reduce coke formation and catalyst deactivation. The process converts oxygen-containing functionalities and unsaturated bonds into chemically reduced forms with an increased hydrogen content.

  • Patent number: 9900137
    Abstract: To address the inefficiency and unfairness issues in channel bonding, a dynamic channel bonding protocol is presented in which a node is allowed to start a transmission as long as a narrow channel is available and gradually increase channel width during transmission whenever a new narrow channel becomes available. The protocol aggregates all available narrow channels as one wide channel, removing the need of setting guard bands between contiguous narrow channels. A challenge in dynamic channel bonding is the communication over uncertain channels. To enable fast spectrum agreement between transmitter and receiver, a partial spectrum correlation method is introduced. When new channels become available, multiple nodes may contend for them. A compound preamble is designed to make collisions detectable in the frequency domain and a parallel bitwise arbitration mechanism is used to quickly resolve the collisions in the time domain.

  • Patent number: 9890457
    Abstract: Microwave plasma assisted reactors, for example chemical vapor deposition (MPCVD) reactors, are disclosed. The disclosed reactors operate at high pressures (>180-320 Torr) and high power densities (>150 W/cm3), and thereby enable high deposition rate CVD processes that rapidly deposit materials. In particular, reactor design examples are described that, when operating in the 180-320 Torr pressure regime, rapidly CVD synthesize high quality polycrystalline (PCD) and single crystal diamond (SCD). The improved reactors include a radial contraction in the vicinity of the plasma chamber (and optionally a combined expansion in the vicinity of the electromagnetic wave source, followed by the contraction) in the main microwave chamber as electromagnetic energy propagates from an electromagnetic wave source to a plasma/deposition chamber.
