  • Patent number: 10702673
    Abstract: A tubular sheath for enclosing an expandable balloon attached to the distal portion of a catheter encloses and protects the expandable balloon. The tubular sheath is configured to be slidable and removable from the catheter. The tubular sheath may include a longitudinal splitting element that is removable as a result of a force applied to the longitudinal splitting element. The longitudinal splitting element is configured to split the wall of the tubular sheath in response to the force. Alternatively, the tubular sheath may include a gripping portion that has relatively poor cohesive strength to adjacent portions of the tubular sheath. The tubular sheath is configured to be removable in response to a force applied to the gripping portion.

  • Patent number: 10672933
    Abstract: A new approach to graphene-enabled plasmonic resonant structures in the THz is demonstrated in a hybrid graphene-metal design in which the graphene acts as a gate-tunable inductor, and metal acts as a capacitive reservoir for charge accumulation. A large resonant absorption in graphene can be achieved using the metal-graphene plasmonic scheme, and the peak can approach 100% in an optimized device, ideal for graphene-based THz detectors. Using high mobility graphene (?>50000 cm2V?1s?1) will allow anomalously high resonant THz transmission (near 100%) through ultra-subwavelength graphene-filled metallic apertures at a resonance frequency that is gate tunable. This metal-graphene plasmonic scheme enables near perfect tunable THz filter or modulator.

  • Patent number: 10549021
    Abstract: A pump having at least a fluid pump chamber (11) and a first driver chamber (12) separated from the fluid pump chamber (11) by an elastic wall (13, 13-1, 13-2) is described with the first driver chamber (12) expanding after a chemical reaction between fuel and oxidant and driving through deformation of the elastic wall fluid out of the fluid pump chamber (11), with the main parts of the pump being made of an elastic material to be used for example as a body implant.

  • Patent number: 10385979
    Abstract: Arrangement for actuating shut-off valve with tapered plug, has housing in which hollow actuating cylinder is coaxially supported for rotation and with an actuating shaft aligned with the coaxial axis firmly attached. Output cylinder is coaxially arranged in hollow actuating cylinder. The output cylinder is movable relative to hollow drive cylinder axially and radially. Spindle is attached on output cylinder opposite actuating shaft and aligned with coaxial axis; tapered plug being fastened on end of spindle facing away from output cylinder. At least one radially outwardly directed pin is arranged on outer peripheral surface of output cylinder. Outer surfaces of housing and hollow actuating cylinder have each at least one guideway extending over radial sector of outer surfaces, with which pin is operatively connected as a respective sliding block. At least the guideway arranged in outer surface of hollow actuating cylinder is formed as a through-opening through which pin passes.

  • Patent number: 10084102
    Abstract: A plasmon-enhanced terahertz graphene-based photodetector exhibits an increased absorption efficiency attained by utilizing a tunable plasmonic resonance in sub-wavelengths graphene micro-ribbons formed on SiC substrate in contact with an array of bi-metallic electrode lines. The orientation of the graphene micro-ribbons is tailored with respect to the array of sub-wavelengths bi-metallic electrode lines. The graphene micro-ribbons extend at the angle of approximately 45 degrees with respect to the electrode lines in the bi-metal electrodes array. The plasmonic mode is efficiently excited by an incident wave polarized perpendicular to the electrode lines, and/or to the graphene micro-ribbons. The absorption of radiation by graphene is enhanced through tunable geometric parameters (such as, for example, the width of the graphene micro-ribbons) and control of a carrier density in graphene achieved through tuning the gate voltage applied to the photodetector.
