A medical implant and method for implantation of the same. One embodiment is an implant for use in the treatment of stress urinary incontinence that includes an implantable, elongated tape having a multiplicity of openings formed through the thickness thereof, the tape having a first end region and a second end region longitudinally opposite the first end region, and first and second bio-compatible fixation elements attached to the first and second end regions of the tape respectively. Each bio-compatible fixation element has a tissue adherence property greater than that of the tape.

A flowmeter has a variable area, vertically-oriented duct through which flows fluid whose flow rate is to be determined. A float in the duct assumes a position in the duct that depends on the flow rate of fluid in the duct. A window is located at an end of the duct in alignment with a longitudinal axis of the duct. A transducer unit projects a light beam through the window and along the axis toward the float. The transducer includes a light sensor that detects light returned by the float by reflection or some other mechanism to the transducer unit. The intensity or other characteristic of the returned light indicates the position of the float in the duct, from which the fluid flow rate may be determined.

The present invention provides a fibrous catalyst-immobilization system that can be employed for immobilizing catalysts that are subject to fluid flow within a chemical production process. The fibrous systems can be synthesized using electrospinning and the catalysts are secured in the fibers during the electrospinning process.

The present invention relates to thickened fabric conditioners, which fabric conditioners contain a particular polymeric thickener, which is obtained by polymerizing from 5 to 100 mole percent of a cationic vinyl addition monomer, from 0 to 95 mole percent of acrylamide, and from 70 to 300 ppm of a difunctional vinyl addition monomer cross-linking agent. As compared to such compositions comprising a similar product but obtained from a polymerization reaction using between 5 and 45 ppm cross-linking agent considerable advantages are obtained. Especially, the delivery of fragrance present in the softening composition is more efficiently carried over to the fabrics to be treated.

Provided is, for example, a method for the fabrication of electrical interconnects in semiconductor devices wherein a substrate including two or more transistors having gate regions wherein the gate regions are not exposed (e.g., the gate regions are completely covered by an insulating cap) is provided. An insulating layer overlying the transistors and the active areas is deposited, where upon a hard mask is created and patterned to form a contact plug/interconnect opening over a first active area and a portion of a first transistor immediately adjacent the first active area. A spacer is formed within the contact plug/interconnect opening. Insulating material overlying active areas between transistors is removed. A portion of the gate region of the first transistor is then exposed and interconnect material is deposited within the contact plug/interconnect opening onto the exposed portion of the gate region of the first transistor and the first active area.

A fuel injector unit comprises a follower assembly that includes a sleeve having an internal groove that receives a spring clip. The clip is made with a spring ring stock having a diameter less then the width of the groove so that the sleeve may be freely rotated around the retainer clip held in the groove. The retainer clip has linear portions aligned along the flat walls of a follower subassembly that receives a plunger carried by the follower assembly. The flat walls terminate at an expanded shoulder that limits displacement of the retainer clip to a fixed height of the follower assembly for shipping and handling, while permitting controlled axial movement of the follower assembly and the plunger along the aligned flat surfaces of the follower subassembly.

An internal combustion rotary engine comprising a housing, at least one sun wheel centered about the central axis and positioned within one of at least one cylindrical compartment of the housing, and including a sun wheel circumference and at least one semicylindrical receptable defined along the sun wheel circumference, at least one lobe extending from an inner cylindrical surface of the compartment, and at least one planet wheel received in the at least one semicylindrical receptable of the sun wheel. The at least one planet wheel may be configured to engage the inner cylindrical surface of the cylindrical compartment and include at least one indentation configured to be received by the at least one lobe when the at least one planet wheel rotates along the inner cylindrical surface. Air intake and compression as well as combustion and exhaust may be performed within the same or different compartments of the at least one cylindrical compartment.

The purpose of diffusion assisted crystal hydrothermal growth is to facilitate a greatly increased crystal growth rate that would save time that is precious in such a material and manpower costly process. The assisted crystal growth itself requires the utilization of a piezoelectric shaker connected to the autoclave in which most industrial hydrothermal crystals are grown. The waveform can be modulated to induce transport of nutrient in a singular direction, customized to the topology of the apparatus. As it stands currently, the growth of most crystals that require autoclaves for their production can take anywhere from 3 months to up to 2 years, and accordingly carries many costs, particularly electricity and supervision of the autoclave(s), and other issues that may arise during the growth. While the product of this labor results in high-quality crystals, in reality, these are not at all what is needed outside of the laboratory environment. Using the assisted crystal hydrothermal growth process, average crystal growth can be cut in half, with the resulting crystals consequently being of a slightly lower quality, though still sufficient for most engineering purposes. Another advantage of using a piezoelectric shaker is that an additional sensor can be added to the autoclave to monitor the health of the autoclave using trending data obtained during the growth.

Systems and methods for generating a model tree structure for a multiphysics modeling system include the acts of transmitting a plurality of selectable physics options for association with at least one of combined systems. An input associated with a selection of at least one of the plurality of selectable physics options is received. One or more selectable study options are transmitted for association with the combined systems. An input associated with a selection of at least one of the one or more selectable study options is received. In response to receiving the input associated with the selection at least one of the one or more selectable study options, a model tree structure is generated using the one or more processing units. The model tree structure includes a plurality of selectable nodes including one or more parent nodes and one or more child nodes. The selectable nodes include fields storing physical quantities and operations for modeling the combined systems.
