  • Patent number: 10845267
    Abstract: Fatigue fuse mounting systems and methods are discussed in this application. It is advantageous in the field of structural monitoring for fatigue fuses that are engineered to break in sequence to both be mounted near each other and also to work toward ensuring the fatigue fuses all undergo similar load cycling. Simply sticking a set of fatigue fuses to a structure can result in each fatigue fuse from an engineered set undergoing different load cycling, which can reduce their effectiveness. Thus, fatigue fuse mounting systems—and methods of implementing the systems—are contemplated in this application. The system includes a structural frame and a fatigue fuse mounting cartridge. These components work together to ensure that each fatigue fuse in a set undergoes more uniform load cycling, thereby improving structural monitoring performance.

    Abstract: A method and device for metrologically differentiating material regions, namely majority regions and minority regions of a page-like, web-like or sheet-like material. At least one sensor receives a measuring signal of variable amplitude, the amplitude being variable depending on the material region located in a spatial detection range of the sensor. The amplitude is increased by a controllable amplifier. The material is moved relatively to the sensor such that majority regions are located in the spatial detection range of the sensor more frequently than minority regions. The method is characterized in that in phases, in which majority regions undergo examination by means of the sensor, by means of the amplifier regulation of the amplitude to a set point is carried out and the sensor generates a signal “majority region”, and that in situations, in which the amplitude undergoes a sufficient change, the sensor generates a signal “minority region”.

  • Patent number: 9264162
    Abstract: A method includes wirelessly transmitting one or more messages to a sensor assembly in order to synchronize a clock of the sensor assembly. The method also includes wirelessly receiving multiple sensor measurements of a characteristic of a web of material from the sensor assembly. The method further includes receiving timestamps and position data associated with the sensor measurements. In addition, the method includes correlating the sensor measurements, timestamps, and position data. The sensor measurements from the sensor assembly could be timestamped, and the position data could include timestamped position data. The timestamped position data could be received from a source other than the sensor assembly. The method can further include generating a cross direction profile of the web of material using the sensor measurements, timestamps, and positions.

  • Patent number: 9097620
    Abstract: A method, and apparatus, for determining bend resistance of a sample includes applying a weight to a sample and measuring an amount of deflection of the sample caused by applying the weight. The sample is provided on a sample holder and an initial position of the sample is measured with respect to the sample holder. A weight is applied to the sample and a change in position from the initial position to a deflection position of the sample due to the weight applied to the sample is measured. An amount of deflection of the sample is determined by dividing the change in position by the basis weight.

  • Patent number: 9016120
    Abstract: A method of determining a testing volume for a micronaire measurement by containing a fiber sample within a micronaire chamber having a length and at least one movable end wall. A flow is initiated along the length of the micronaire chamber. The fiber sample is compressed within the micronaire chamber by advancing the movable end wall, and the advancement of the movable end wall is stopped when at least one property of the flow attains a set point. The position of the movable end wall defines the testing volume. In this manner, there is provided a convenient method of setting a testing volume and acquiring the information needed to take a micronaire measurement.

  • Patent number: 8957688
    Abstract: An apparatus for determining at least one dielectric property of a capacitor arrangement, and especially for capacitive examination of a moving elongated test subject such as yarn. It contains an alternating signal generator for applying an electric alternating signal to the capacitor arrangement. The capacitor arrangement is uncoupled from the alternating signal generator by means of an amplifier in such a way that it does not relevantly influence the basic frequency and the signal shape of the applied alternating signal. Detection means detect an electric measuring variable of an electric signal tapped from the capacitor arrangement. The alternating signal generator is set up in such a way that at least one of the basic frequency and the signal shape of the applied alternating signal can be changed.

  • Publication number: 20140311236
    Abstract: A method and device for metrologically differentiating material regions, namely majority regions and minority regions of a page-like, web-like or sheet-like material. At least one sensor receives a measuring signal of variable amplitude, the amplitude being variable depending on the material region located in a spatial detection range of the sensor. The amplitude is increased by a controllable amplifier. The material is moved relatively to the sensor such that majority regions are located in the spatial detection range of the sensor more frequently than minority regions. The method is characterized in that in phases, in which majority regions undergo examination by means of the sensor, by means of the amplifier regulation of the amplitude to a set point is carried out and the sensor generates a signal “majority region”, and that in situations, in which the amplitude undergoes a sufficient change, the sensor generates a signal “minority region”.
