  • Patent number: 10145773
    Abstract: A system and method for measuring the deformation over time of the surface of a non-Newtonian fluid in a sampling container in response to an airjet that is applied for a specified time are disclosed. The change is the sample surface displacement is measured quantitatively by means of optical triangulation or other similar optical or electronic distance measuring device. After cessation of the airjet, gravitational forces cause the sample material to flow back to its original surface profile. Both the amplitude of the deformation displacement due to the force of the airjet and the recovered displacement, within specific time periods are characteristic of asphalt binder material with varying amounts of polymer or other additives used to control the ultimate properties and performance of the material. As a result, comparison of the quantitative measurements of control samples can allow discrimination from samples with different properties and hence different formulations.

  • Patent number: 10126199
    Abstract: An apparatus and a system is provided that may be utilized to determine oil migration and oil displacement from a pre-oiled air filter. The present invention may also be utilized to determine if oil is displaced from the air filter onto a portion of the apparatus for visualization to a user. The present invention utilizes a demonstration apparatus having a system for forcing air through the oil subjected air filter thereby attempting to force displacement of the oil from the air filter. The apparatus utilizes a blowing means whereby the oil infused air filter is subject to higher than normal air flow and whereby the apparatus has a deflection portion whereby if oil is displaced from the air filter, it is deflected onto the deflection portion where it would be physically viewable to an observer present in the vicinity of the apparatus.

  • Patent number: 10119875
    Abstract: A pressure sensor device with a MEMS piezoresistive pressure sensing element attached to an in-circuit ceramic board comprises a monolithic ceramic circuit board formed by firing multiple layers of ceramic together. The bottom side of the circuit board has a cavity, which extends through layers of material from the ceramic circuit board is formed. A ceramic diaphragm, which is one of the layers, has a peripheral edge. The diaphragm's thickness enables the diaphragm bounded by the edge to deflect responsive to applied pressure. A MEMS piezoresistive pressure sensing element attached to the top side of the ceramic circuit board generates an output signal responsive to deflection of the ceramic diaphragm. A conduit carrying a pressurized fluid (liquid or gas) can be attached directly to the ceramic circuit board using a seal on the bottom of the ceramic circuit board, which surrounds the opening of the cavity through the bottom.

  • Patent number: 10119882
    Abstract: Systems, devices, and methods for leak testing surgical conduit grafts or valved conduits such as aortic-valved conduits with a pressurized gas such as air. Air is non-destructive and especially useful for leak testing conduits that have coatings or sealants that may be functionally impacted when exposed to fluids such as water or saline. Open ends of the conduit are clamped and sealed, and a pressurized gas introduced into an inner lumen thereof. A change in mass flow rate is measured to quantify the leakage. One end of a tubular conduit may be clamped to a fixed manifold, and the opposite end to a manifold slidably mounted to accommodate any conduit elongation when pressurized. The clamping and sealing structure may be pneumatic and/or mechanical, and complementary contoured clamp members may be used to seal a scalloped external sealing ring of an aortic conduit.
