  • Patent number: 10768130
    Abstract: Hundreds of thousands of concrete bridges, buildings etc. and hundreds of billions of tons of concrete require characterization throughout the process from manufacture to pouring and curing and on throughout service life. The characterization may relate to initial concrete properties, projected concrete properties, framework removal, corrosion, failure etc. Accordingly, a variety of measurements such as water content, electrical resistivity, and half-cell corrosion potential for example would be beneficially implemented as easy to use field test equipment or embedded sensors allowing lifetime monitoring to be performed rather than discrete assessments when issues become evident.

  • Patent number: 10739289
    Abstract: Hundreds of thousands of concrete bridges and hundreds of billions of tons of concrete require characterization with time for corrosion. Accordingly, protocols for rapid testing and improved field characterization systems that automatically triangulate electrical resistivity and half-cell corrosion potential measurements would be beneficial allowing discrete/periodic mapping of a structure to be performed as well as addressing testing for asphalt covered concrete. Further, it is the low frequency impedance of rebar in concrete that correlates to corrosion state but these are normally time consuming vulnerable to noise. Hence, it would be beneficial to provide a means of making low frequency electrical resistivity measurements rapidly. Further, prior art techniques for electrical rebar measurements require electrical connection be made to the rebar which increases measurement complexity/disruption/repair/cost even when no corrosion is identified.

  • Patent number: 10725076
    Abstract: A system for monitoring dielectric constant of a substrate includes a resonator structure formed on a surface of the substrate. A distal end of a waveguide is coupled to the resonator structure and spaced apart from the resonator structure such that a gap is provided between the distal end of the waveguide and the resonator structure. An excitation energy is coupled to the resonator structure out of the waveguide, and a response energy from the resonator structure is coupled into the waveguide and is detected at a proximal end of the waveguide. A detector detects the response energy received at the proximal end of the waveguide and generates a signal indicative of the detected response energy. A processor is coupled to the detector for receiving the signal indicative of the detected response energy and processing the signal to determine dielectric constant of the substrate.

A rotation arm and a pressurizer are provided on one end of the oscillation arm. One end of the rotation arm is rotatably attached to the oscillation arm, and a load weight is placed on the other end of the rotation arm. By rotating the rotation arm, the magnitude of a force to be applied by the load weight to the pressurizer is adjusted. More specifically, by displacing the load weight to a predetermined position by rotation and then causing the load weight to stop at this position, a static load corresponding to the rotation angle can be applied to the pressurizer. Further, by causing the load weight to perform rotational motion, the magnitude of the force to be applied to the pressurizer is periodically varied, so that a load which varies periodically can be applied to hard tissue.

The stiffness detector receives leaky waves of the Lamb waves propagated through the paper sheet at different angles with respect to the paper sheet by a plurality of reception sensors. The stiffness detector is configured to specify a maximum leak angle at which a leak amount of the acoustic waves from the paper sheet becomes maximum based on outputs from the plurality of reception sensors in the reception module and to judge a degree of fatigue of the paper sheet based on the specified maximum leak angle.

  • Patent number: 8109134
    Abstract: In a method for determining the degree of hardening or drying of one or more printed ink and/or coating film(s) on a substrate, for instance, paper, cardboard, plastic film or composite materials, a faster and more efficient measuring method can be found that furthermore supplies secure and easily interpreted results. The method is to be used in the mass production printing processes comprising intaglio printing, flexographic printing, screen printing or offset printing. The degree of hardening or drying is determined indirectly by way of the change in the mechanical and/or viscoelastic properties of the ink and/or coating films on the substrate that result from the hardening or drying process. The detection of acoustic waves by means of a piezoelectric sensor is used as the measuring method.

  • Patent number: 8058613
    Abstract: The present disclosure describes micromechanical devices and methods for using such devices for characterizing a material's strength. The micromechanical devices include an anchor pad, a top shuttle platform, a nanoindenter in movable contact with the top shuttle platform and at least two sample stage shuttles. The nanoindenter applies a compression force to the top shuttle platform, and the at least two sample stage shuttles move apart in response to the compression force. Each of the at least two sample stage shuttles is connected to the top shuttle platform and to the anchor pad by at least one inclined beam. Methods for using the devices include connecting a sample between the at least two sample stage shuttles and applying a compression force to the top shuttle platform. Application of the compression force to the top shuttle platform results in a tensile force being applied to the sample. Measuring a tip displacement of the nanoindenter is correlated with the sample's strength.

  • Publication number: 20110236656
    Abstract: This homogenized, multilayer sandwich structure has a total bending stiffness. The structure has two external skins each of a material having a modulus, a thickness and a width with contribution to the total moment of inertia. The structure also has a core of a foam material sandwiched between the two external skins, wherein the core has a modulus, a thickness and a width with contribution to the total moment of inertia. The external skins are fixed to the core, the strength of the structure being dependent on the core thickness via cubic power, as well as on the placement of the layers within the structure.

    Abstract: An apparatus for conducting demonstrations of the softness properties of consumer products and other materials, plus a method for conducting such demonstrations, is provided. A sample of paper towels, toilet tissue, or facial tissue, or other consumer products is placed in the apparatus. The apparatus drops an egg or other fragile object onto the sample, or the egg may be dropped from an operator's hand into the apparatus and onto the sample. By displaying the egg or fragile object as it either lands safely on a sample or is destroyed on impact, the operator can visually demonstrate to an average consumer either the softness properties of the sample, or the lack thereof. A method of preparing samples in a consistent manner is also provided to ensure that results are as fair, uniform and repeatable as possible.

    Abstract: A PEFS (Piezoelectric Finger Sensor) acts as an “electronic finger” capable of accurately and non-destructively measuring both the Young's compression modulus and shear modulus of tissues with gentle touches to the surface. The PEFS measures both the Young's compression modulus and shear modulus variations in tissue generating a less than one-millimeter spatial resolution up to a depth of several centimeters. This offers great potential for in-vivo early detection of diseases. A portable hand-held device is also disclosed. The PEF offers superior sensitivity.

  • Patent number: 7681438
    Abstract: A probe for measuring the hardness of concrete includes a body adapted to receive a retainer such that the combined body and retainer can be held in an aperture extending through a wall of a mould for the hardenable material, with the body extending from the inside of the wall. A sensor circuit includes detector elements supported by the body and disposed when in use in the concrete, and circuit terminals which face the exterior of the mould wall when in use, and are accessible through the retainer for connection to terminals of an external instrument. Preferably, the detector elements are conductive portions of a printed circuit board forming a resonator. The instrument can operate a switch in the probe which interconnects the terminals to indicate a good connection and measures resonator impedance at multiple frequencies.
