  • Patent number: 10241021
    Abstract: A method includes measuring a leakage current through a particulate matter sample in a humidity chamber, the leakage current is measured as a relative humidity in the humidity chamber is incrementally increased, and plotting a logarithm of the measured leakage current as a function of the relative humidity. The plot of the logarithm of the measured leakage current as a function of the relative humidity has an inversion region, a low relative humidity region, and a high relative humidity region.

  • Patent number: 10234061
    Abstract: Formed hose configurations are provided which include an innermost elastomer layer, a first fiber-reinforcement region, and multiple second fiber-reinforcement regions. The first fiber-reinforcement region has a first fiber-reinforcement density, and is disposed, at least in part, at a bend region of the formed hose, and the multiple second fiber-reinforcement regions have a second fiber-reinforcement density, and are disposed at least at the first and second end regions of the formed hose. The second fiber-reinforcement density is greater than the first fiber-reinforcement density, and results in the first and second ends of the formed hose being less radially-deformable than the bend region of the hose. This facilitates providing a mechanical fluid-tight connection with a hose barb fitting when the formed hose is slid over the hose barb fitting, absent any clamp over the formed hose and hose barb fitting connection.

  • Patent number: 9733148
    Abstract: Embodiments of the present invention provide moisture measuring systems and methods. According to one embodiment of the present invention, a sealable compartment is used in which a specimen containing liquid can be inserted, such that all of the specimen is contained within the compartment. The relative humidity in the compartment is measured over a duration of time, which can be used to calculate the amount of liquid leaked by the specimen. Embodiments of the present invention can be utilized, for example, to calculate the leakage rate of water-carrying hardware of a cooling system, without having to create a membrane or other isolated sample of materials.

  • Patent number: 9575040
    Abstract: A corrosion sensor includes a plurality of metal strips having different thicknesses. A first metal strip with the least thickness is first employed to provide sensitive corrosion detection. After an exposed portion of the first metal strip is consumed, a second metal strip having a second least thickness can be employed to provide continued sensitive corrosion detection employing a remaining un-corroded portion of the second metal strip. The plurality of metal strips can be sequentially employed as exposed portions of thinner metal strips become unusable through complete corrosion and un-corroded exposed portions of thicker metal strips become thin enough to provide sensitive corrosion detection.
