  • Patent number: 10156149
    Abstract: Various embodiments of the invention include turbine nozzles and systems employing such nozzles. Various particular embodiments include a turbine nozzle having: an airfoil having: a suction side; a pressure side opposing the suction side; a leading edge spanning between the pressure side and the suction side; and a trailing edge opposing the leading edge and spanning between the pressure side and the suction side; and at least one endwall connected with the airfoil along the suction side, pressure side, trailing edge and the leading edge, the airfoil having a fillet at the trailing edge proximate the at least one endwall.

  • Patent number: 9846032
    Abstract: Systems, methods, for three-dimensional (ā€œ3Dā€) and computer-readable media fluid scanning are provided. According to some embodiments, there is provided a method that may include adding a first predetermined amount of fluid into a container, measuring a first fluid height in the container after the adding the first predetermined amount of fluid, adding a second predetermined amount of fluid into the container when the first predetermined amount of fluid is in the container, measuring a second fluid height in the container after the adding the second predetermined amount of fluid, emptying the fluid from the container.

  • Publication number: 20070123929
    Abstract: A filter for filtering micro-emboli from a patient's blood during an angioplasty procedure is disclosed which comprises a plurality of curved wires connected to a rod between a first connector fixed with respect to the rod and a second connector slidingly mounted on the rod. Two layers of filter material are connected to opposite sides of the wires, and each layer includes perforations which are offset from the perforations in the other layer. When the rod and the wires are disposed within a catheter, the inner wall of the catheter compresses the wires toward the rod and when the rod is extended from the catheter, the wires resume their curved shape and pull the sliding connector along the rod toward the fixed connector.
