  • Patent number: 9851199
    Abstract: The invention embodies methods and apparatuses to monitor and control the characteristics of a creping process. The method involves measuring optical properties of various points along a creped paper sheet and converting those measurements into characteristic defining data. The invention allows for determining the magnitude and distribution of crepe structures and their frequency and distribution. This allows for the generation of information that is accurate and is much more reliable than the coarse guessing that is currently used in the industry. Feeding this information to papermaking process equipment can result in increases in both quality and efficiency in papermaking.

The testing includes subtracting the middle input value form the high input value to calculate a first difference, and comparing an absolute value of the first difference to a failure threshold. A first intermediate value is determined based on the comparison of the first difference to the failure threshold. The testing also includes subtracting the middle input value from the low input value to calculate a second difference, and comparing the second difference to the failure threshold. A second intermediate value is determined based on this comparison. The first intermediate value and second intermediate value are averaged to produce an output based on the three input values.

    Abstract: Methods and sensors for selective fluid sensing are provided. Each sensor includes a resonant inductor-capacitor-resistor (LCR) sensor that is coated with a sensing material. In order to collect data, an impedance spectrum is acquired over a relatively narrow frequency range, such as the resonant frequency range of the LCR circuit. A multivariate signature may be calculated from the acquired spectrum to discern the presence of certain fluids and/or fluid mixtures. The presence of fluids is detected by measuring the changes in dielectric, dimensional, resistance, charge transfer, and other changes in the properties of the materials employed by observing the changes in the resonant electronic properties of the circuit. By using a mathematical procedure, such as principal components analysis (PCA) and others, multiple fluids and mixtures can be detected in the presence of one another, even in a high humidity environment or an environment wherein one or more fluids has a substantially higher concentration (e.g.

  • Patent number: 8981018
    Abstract: The condition of internal or hidden material layers or interfaces is monitored and used for control of a process that changes a condition of a material system. The material system has multiple component materials, such as layers or embedded constituents, or can be represented with multiple layers to model spatial distributions in the material properties. The material condition changes as a result of a process performed on the material, such as by cold working, or from functional operation. Sensors placed proximate to the test material surface or embedded between material layers are used to monitor a material property using magnetic, electric, or thermal interrogation fields. The sensor responses are converted into states of the material condition, such as temperature or residual stress, typically with a precomputed database of sensor responses.

  • Patent number: 8970202
    Abstract: A shift sensor includes a movable member, four movable contacts, seven fixed contacts, and two power supply terminals. Each of the movable contacts is fixed to the movable member and pivoted to a position corresponding to a shift position. Each of the fixed contacts outputs a shift signal when it is brought into conduction with a power supply terminal by coming into contact with any of the movable contacts. The fixed contacts are arranged such that the number of shift signals that differ between shift positions is three or more, between the shift positions of P, R, N, D, and B, except for between the D and B positions.
