  • Patent number: 9718713
    Abstract: A system is provided for removing arsenic from water to safe levels at or below the EPA standards. The system is a hybrid spouted vessel/fixed bed filter system that significantly enhances/improves arsenic removal for drinking water using zero-valent iron (ZVI) particles. Movement of the circulating, iron-containing particles in a dense moving bed that forms on the spouted vessel bottom creates an abrasive “self-polishing” action among them that continuously generates colloidal iron corrosion products. This material then circulates with the water in the vessel and is removed and concentrated in a fixed bed filter. The colloidal material captured and immobilized in the filter has been shown to remove arsenic from contaminated water at very rapid rates.

  • Publication number: 20170182165
    Abstract: A thermal accelerant is delivered to a tissue site and localized to modulate the shape, extent or other characteristic of RF or microwave-induced hyperthermic tissue ablation. The accelerant may be provided via an image-guided hand piece or via a lumen added to a microwave antenna, and promotes faster heating, more complete ablation and/or a more extensive treatment region to reduce recurrence of treated cancers, overcoming natural limitations, variations in tissue response and drop-off or thermal loss away from the antenna. The accelerant is delivered as a low-viscosity but heat sensitive fluid, and is fixed in place to provide regions of preferential absorption or heating. Shorter exposure times to heat the far field may allow survival of vulnerable tissue such as vessels, and multiple antennae may be used for effective treatment of irregular or large tumors.

  • Patent number: 9679409
    Abstract: Systems, methods, and computer-readable storage media for simulating realistic clothing. The system generates a clothing deformation model for a clothing type, wherein the clothing deformation model factors a change of clothing shape due to rigid limb rotation, pose-independent body shape, and pose-dependent deformations. Next, the system generates a custom-shaped garment for a given body by mapping, via the clothing deformation model, body shape parameters to clothing shape parameters. The system then automatically dresses the given body with the custom-shaped garment.

  • Patent number: 9662880
    Abstract: A method and structure for a piezoelectric ink jet printhead. The method can include forming a piezoelectric composite from a liquid sol-gel solution. A first layer of the liquid sol-gel solution can be deposited onto a substrate using, for example, a spin coat process, wherein the substrate may be a printhead diaphragm. The first layer may be partially cured, then a second layer of the liquid sol-gel solution can be deposited onto the partially cured first layer, which is then partially cured. Any number of layers of liquid sol-gel solution can be deposited to result in a piezoelectric composite having a suitable thickness. Subsequently, all of the partially cured layers are fully cured. Printhead processing can continue to form a completed piezoelectric ink jet printhead.

  • Patent number: 9611168
    Abstract: A method and apparatus to manufacture a coherent bundle of scintillating fibers is disclosed. In the method and apparatus, a polymer matrix of a transparent polymer and nanoparticle scintillators is placed on top of a collimated bundle having a plurality of capillaries and pressed in a pressure vessel until the polymer matrix is forced into the capillaries. Pressure is applied via an anvil on top of the polymer matrix. To prevent fracturing of the collimated bundle during pressing, back pressure is supplied to the pressure vessel via a valve, which controls a supply of high pressure gas. Alternatively, the back pressure may also be supplied by a press (and or pressure) and support to the collimated bundle is provided by a high melting point thermoplastic. Heat may be applied to the polymer matrix via the anvil to speed the pressing operation due to the viscosity of the polymer.

  • Publication number: 20170082873
    Abstract: Systems, apparatuses, and methods for modulating light at high frequencies by addressing the issue of direct modulation of long lifetime light emitters. Dynamic control of the local density of optical states (LDOS) to exploit the differences between electric and magnetic dipole transitions allows for higher frequency modulation. The LDOS is controlled, in part, by designing a structure such that it enhances or suppresses electric and magnetic dipoles. Direct modulation may be achieved by designing the optical environment to adjust the interferences between the emitted light field and its own reflection at the emitter's location. The optical environment may include light emission material, switchable material, spacer materials, and reflective materials.

  • Patent number: 9489744
    Abstract: A novel “contour person” (CP) model of the human body is proposed that has the expressive power of a detailed 3D model and the computational benefits of a simple 2D part-based model. The CP model is learned from a 3D model of the human body that captures natural shape and pose variations; the projected contours of this model, along with their segmentation into parts forms the training set. The CP model factors deformations of the body into three components: shape variation, viewpoint change and pose variation. The CP model can be “dressed” with a low-dimensional clothing model, referred to as “dressed contour person” (DCP) model. The clothing is represented as a deformation from the underlying CP representation. This deformation is learned from training examples using principal component analysis to produce so-called eigen-clothing. The coefficients of the eigen-clothing can be used to recognize different categories of clothing on dressed people.

  • Patent number: 9468680
    Abstract: Drugs are screened for affects on inhibiting efflux pumps and blocking gap junction communication in tumors by culturing cells to thereby form self-assembled spheroids and incubating the spheroids. Uptake of a substrate of the efflux pump and distribution of a substrate for the efflux pump within the spheroids is imaged to thereby select drugs that inhibit the efflux pump or do not block gap junction communication. Selected drugs can then be employed to treat a tumor.

  • Patent number: 9453061
    Abstract: Therapeutic compositions for treatment of protein serine/threonine phosphatase-related diseases are obtained by engineering amino acid sequences that disrupt interaction between the protein serine/threonine phosphatase and a protein inhibitor and are provided herein. Calcineurin and PPI are examples of protein serine/threonine phosphatases. RCAN1 is an inhibitor of calcineurin and is overexpressed in patients with serious diseases, such as Down syndrome and Alzheimer's disease. Molecules that bind RCAN1 at regions that interact with calcineurin selectively modulate functions of calcineurin to treat these diseases. Methods of treating a subject for a protein serine/threonine phosphatase-related disease by administering a molecule having an amino acid sequence selected from the group of SEQ ID NOs: 1-19 are further provided.
