  • Patent number: 10860001
    Abstract: A method of designing and manufacturing a replica composite object based on an original object. The method identifies the structure and physical properties of an original object. Base materials, bodies, and structural templates, each of which includes associated physical properties, are utilized to generate a 3-dimensional model. The 3-dimensional model is discretized and tested to determine if the selected combination of base materials and bodies have physical properties that substantially equal the physical properties of the original object. If the physical properties do not equate, the 3-dimensional model is optimized by adjusting the combination of base materials, bodies, and structural templates. When the difference between the measured physical properties of the 3-dimensional model and the identified physical properties of the original object is less than a tolerance value, the method instructs an additive manufacturing system to generate a replica composite object based on the original object.

  • Patent number: 10854098
    Abstract: A wound simulation unit is a physical device designed to help simulate a wound on an object (e.g., a human being or human surrogate such as a medical manikin) for instructing a trainee to learn or practice wound-related treatment skills. For the trainee, the simulation looks like a real wound when viewed using an Augmented Reality (AR) system. Responsive to a change in the anatomic state of the object (e.g., bending a knee or raising of an arm) not only the spatial location and orientation of the wound stays locked on the object in the AR system, but the characteristics of the wound change based on the physiologic logic of changing said anatomical state (e.g., greater or less blood flow, opening or closing of the wound).

  • Patent number: 10852033
    Abstract: An insulation system for a water heater storage tank containing water heated to a temperature higher than ambient is provided. The water heater tank has a substantially cylindrical shape and a generally circular top portion from which one or more pipes extend. A top insulation structure having two half-moon shaped insulation segments lies on the top portion insulating most of it against heat loss to the ambient environment. The insulation segments each comprise an envelope of pliable heat-resistant sheet material enclosing shapeable insulating filler material of particles. The envelopes are deformable to conformingly fit between and around pipes projecting up from the top of the water heater. An insulating jacket extends around and covers a substantial portion of a radially outwardly disposed surface of the water heater tank.

  • Patent number: 10848057
    Abstract: A two-stage microinverter for coupling a PV panel to a power grid includes a DC/DC converter stage having an input for coupling to the PV panel and a DC/AC inverter stage that has an output for coupling to the grid, with at least one DC link capacitor between the DC/DC converter and DC/AC inverter stage. A synchronous controller that includes a loop compensator coupled to a mixer is between an analog-to-digital converter (ADC) and a phase-locked loop (PLL) for coupling to an output voltage from the grid. The ADC receives a DC link voltage from the DC link capacitor. An output of the PLL is for controlling a timing of sampling by the ADC of the DC link voltage so that the ADC samples the DC link voltage when an AC component of a ripple voltage on the DC link voltage intersects an average value of the DC link voltage.

  • Patent number: 10840925
    Abstract: Apparatus and methods demonstrate a chip-scale direct optical to RF link that frequency divides up to 120 GHz optical frequency combs to 10 GHz using harmonic multi-tone injection locking. The embodied invention links widely separated optical frequency combs in the millimeter wave regime (>120 GHz) or THz domain (100s of GHz to THz domain), e.g., microresonator-based frequency combs, which are currently outside of the photo-detection region, into the microwave domain (10s of GHz) where it can be easily photo-detected and controlled. The technique works as a perfect optical divider, using a mode-locked laser and optical injection locking as the technique to phase-lock both lasers.

  • Patent number: 10825210
    Abstract: An apparatus and method are provided for computed tomography (CT) imaging to reduce truncation artifacts due to a part of an imaged object being outside the scanner field of view (FOV) for at least some views of a CT scan. After initial determining extrapolation widths to extend the projection data to fill a truncation region, the extrapolation widths are combined into a padding map and smoothed to improve uniformity and remove jagged edges. Then a hybrid material model fits the measured projection data nearest the truncation region to extrapolate projection data filling the truncation region. Smoothing the padding map is improved by the insight that in general smaller extrapolation widths are more accurate and trustworthy. Further, practical applications often include multiple inhomogeneous materials. Thus, the hybrid material model provides a better approximation than single material models, and more accurate fitting is achieved.

  • Patent number: 10787963
    Abstract: A power generation system burns a fuel in a gas in a combustion chamber, producing one or more combustion products and heating a working fluid, preferably supercritical CO2, that is chemically the same as a combustion product. The working fluid is mixed with the combustion products to form a combustion output mixture which is used in a turbine to drive a shaft of the turbine connected with a generator, producing electricity. The turbine outputs an exhaust that goes to a working fluid recycling system that connects the turbine outlet with the combustion chamber. The fluid recycling system has a radial compressor that receives and pressurizes the exhaust mixture and sends it to a chamber that has a bleed outlet and a recycling outlet.
