Abstract: A loading tool to facilitate loading a prosthesis into a delivery system includes a hinged body with first and second body portions and a collar slidingly disposed over the hinged body. First ends of the body portions are attached and second ends of the body portions are not attached. Each body portion includes a resilient clip that includes a radial protrusion. Each resilient clip is configured to displaced radially inwards when a pinching force is applied thereto. The loading tool has an open configuration in which the second ends are radially spaced apart and the collar is disposed over the first ends. The loading tool has a closed configuration in which the second ends are disposed directly adjacent to each other and the collar is disposed over the second ends. The radial protrusions lock the loading tool in the closed configuration when the resilient clips are not displaced radially inwards.

Abstract: A mask pattern for a semiconductor device can be used as an input to determine a photoresist thickness probability distribution using a machine learning module. For example, the machine learning module can determine a probability map of Z-height. This can be used to determine stochastic variation in photoresist thickness for a semiconductor device. The Z-height may be calculated at a coordinate in the X-direction and Y-direction.

Abstract: An apparatus for modifying biological material and methods of use and assembly. The apparatus includes a base, a frame coupled to the base, and an adjustable arm assembly coupled to the frame and positioned above the base. The adjustable arm assembly includes a positioning arm extending from a first arm end to a second arm end, where the first arm end is coupled to the frame, and where the second arm end extends away from the frame towards the base. The adjustable arm assembly includes a blade-coupling-member assembly coupled to the second arm end.

Abstract: Certain embodiments include a computer mouse including a housing having a bottom surface and a trackball disposed in the housing, where the bottom surface of the housing includes a first planar region, a second planar region, and a spine both common to and dividing the first and second planar regions. The first and second planar regions can be on different planes, where, when in operation, the computer mouse is configured to rest on a work surface, when the computer mouse is configured such that the first planar region of the bottom surface is parallel to the work surface, the computer mouse is tilted at a first angle relative to the work surface, and when the computer mouse is configured such that the second planar region of the bottom surface is parallel to the work surface, the computer mouse is tilted at a second angle relative to the work surface.

Abstract: A first stage turbine disk section for a gas turbine engine, including a centrally disposed disk hub having an integrally-formed, radially outwardly extending web terminating at an outer end. The disk hub has a convex, curved hub surface exposed to high pressure, high temperature compressor bleed and discharge gases during engine operation, and the convex, curved hub surface acts to reduce the axial constraint at the location of peak axial stress, thereby mitigating the formation of undesirable axial stress in the disk hub and allows separation of the peak axial and hoop stresses, thereby reducing the magnitude of the peak hub surface effective stress.

Abstract: A gas turbine engine disk that includes a centrally disposed disk hub having an integrally-formed, radially outwardly extending web terminating at an outer end. The disk hub has a radially-displaced annular hub surface exposed to high pressure, high temperature discharge gases during engine operation. The radially-displaced annular hub surface acts as an axial free surface mitigating the formation undesirable axial stress in the disk hub.

Abstract: A gas turbine section of a gas turbine engine, including a first stage turbine disk, a forward outer seal carried on the turbine disk. and a forward shaft cooperating with the first stage turbine disk for transmitting torque generated by the turbine section to a compressor section of the engine. The forward shaft intersects the first stage turbine disk at a non-perpendicular angle in the area of the disk hub for directing sufficient hot air against the disk hub to balance the thermal response rate of the disk hub to the thermal expansion rate of the forward outer seal.

Abstract: A welding method that enables the joining of at least two dissimilar, metallic alloys to form a weld that is free of cracks is disclosed. The method incorporates a pure (99.00% minimum by weight) nickel fill-wire, integrally assembled into the joint between the two alloyed metals to be joined. The alloys joined by this method are an iron-based, low expansivity, gamma-prime strengthened superalloy (i.e., Incoloy®) and a high carbon, powder metallurgical tool steel high in refractory metal alloying agents (i.e., CPM REX 20). Welding of the joint results in the formation of a nickel rich region within the weld, thus “inoculating” the weld against cracks. The weld joint formed by the method of the present invention can be used in the fabrication of a rotating anode bearing shaft assembly for use in an x-ray generating device.

Abstract: An x-ray tube and x-ray system including an anode assembly having a shaft with a first end and a second end, a target connected to the first end of the shaft, and a rotor connected to the second end of the shaft. The anode assembly further having spaced-apart bearings rotatably supporting the shaft. The shaft, target, and rotor positioned relative to each other such that the center of gravity of the combination of the shaft, the target, and the rotor is positioned between the bearings. Additionally, the target and rotor may be flexibly interconnected allowing the beneficial use of gyroscopic effects.
