Abstract: An endovascular interventional method is provided that includes the steps of: inserting a catheter into a target blood vessel, wherein the catheter is coupled to a system that provides a continuous delivery of contrast and of a hyperosmotic fluid supply; injecting the contrast and determining a rate of flow that achieves angiographic filling of the target blood vessel at a first time; injecting the hyperosmotic fluid continuously at the rate of flow that achieves angiographic filling at the first time for a first period of time; injecting the contrast and determining a rate of flow that achieves angiographic filling of the target blood vessel at a second time following the first period of time; and injecting the hyperosmotic fluid continuously at the rate of flow that achieves angiographic filling at the second time for a second period of time.

Abstract: The present application provides systems that include a controller, and an insertion device with at least one temperatures sensor thereon and a pump coupled to the controller. The insertion device provides temperature measurement(s) at/of a subject's organ to the controller and the controller varies an infusate flow rate to induce temperature changes in at least a portion of the subject's organ and stores the temperature measurements during perfusion induced temperature changes on a memory device. The controller may estimate at least one hemodynamic characteristic of at least a portion of the subject's organ based on the temperature measurements obtained during perfusion induced temperature changes.

Abstract: Systems and methods can produce thermal images of the mounting of a thermally-enhanced integrated circuit (IC) upon a circuit board. The system includes a thermal imaging camera that is operable to image the thermal dissipation and/or conduction through the heat sink into a mounting pad on the substrate. In testing the thermally-enhanced IC, the substrate or IC is connected to a power source, and the IC is operated such that the IC begins to generate heat. As the heat is conducted or dissipated through the heat sink into the mounting pad, a thermal imaging camera can detect the heat conduction and/or dissipation through the heat sink into the substrate. If there are voids or other types of failures in the mounting of the IC, the thermal imaging camera can detect cooler or colder spots in the image.

Abstract: The present invention provides an image enhancer that can be applied to various materials during quality testing. The image enhancer is adapted to infiltrate cracks, crevices, fractures, fissures, and other faults, defects, or flaws in the material and provide an increased contrast for images taken by, for example, an X-ray imaging device.

Abstract: An electromagnetically-shielded enclosure is formed by applying an electromagnetic-shielding film to a plastics enclosure by the water-borne film application process. The film is formed from a mixture comprising a polymer and a conductive material, such as lossy ferrite, carbon glass, or metal, that constitutes 20 to 40 percent by weight of the mixture.

Abstract: It has been found that the properties of poly(vinyl chloride) based polymers are substantially enhanced through the use of a specific plasticizer system. In particular, the use of specific triarylphosphates in combination with specific diarylphosphates in specific proportions not only plasticizes the PVC polymer but produces a transparent, flame retardant heat resistant, easily worked polymer. These materials are used so that the diarylphosphate is 30-45% of the total concentration of the phosphates and such that 45 to 70 parts of the phosphates are present per 100 parts of the polymer.

Abstract: A wide variety of products are formed by compression molding of silicone materials. Although such articles are used in numerous applications, compression molding is expensive and exudation of unreacted monomers and oligomers tend to cause electrical contact failures. By employing specific polyurethanes formed from polyols and isocyanates, it is possible to form articles by reaction injection molding. This process is substantially cheaper than compression molding and yet the same properties obtainable with silicones are attained.
