  • Patent number: 11699127
    Abstract: A system and method for tracking fiber along a textile supply chain aids in product tracking and can verify fiber source/origin. However, verifying the fiber origin and type in a textile product purchased at a retail location back to the bale is complicated by the nature of textile processes along the supply chain. The system as described in the present application addresses complications, such as contamination/cross-contamination, and is used to track fiber from bales of fiber processed into a textile product throughout a sequence of textile operations. The system captures, for each textile operation, a) input information, b) output information, and c) equipment information related to the equipment used in the textile operation. The output information is associated with the input information of a subsequent textile operation, thereby associating the input information and output information, for each textile operation, with the fiber information for the bales of fiber.

  • Patent number: 11570849
    Abstract: A wireless instrument area network node employs an internal force sensor arrangement to detect user-provided force on the node and initiate a node operation, such as wake the node from a sleep state or low power mode to a more power-hungry awake and processing state. The internal force sensor avoids the need to provide external buttons, a screen, and the like on the surface of the node that could lead to intrusion of fluids, gases, or other unwanted substances into the node. In some embodiments, the internal sensor may include a microswitch that has sufficient sensitivity to detect even a very small amount of deflection resulting from, for example, a hand touch. In some embodiments, the internal sensor may include a piezoelectric sensor that has similarly high deflection sensitivity. Multiple such deflection detectors may be at different angles to one another deployed to provide greater directional coverage for the deflection.

    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.

  • Patent number: 10054525
    Abstract: A testing instrument and method for measuring the intrinsic strength of polymeric materials via cutting includes a pair of mechanical clamps connected at a base to low-friction hinges. The clamps are configured to secure the elongate edges of a polymer specimen, and to periodically load the specimen to a predetermined strain. The load on the specimen while strained is measured with an opening force load sensor. While in the strained condition, the specimen is cut with a highly sharpened blade, and the cutting force also measured by a cutting force load sensor. A cutting energy curve may be plotted from these measurements, from which a cutting energy can further be derived.

  • Patent number: 9811804
    Abstract: A system and method for tracking fiber along a textile supply chain aids in product tracking and can verify fiber source/origin. However, verifying the fiber origin and type in a textile product purchased at a retail location back to the bale is complicated by the nature of textile processes along the supply chain. The system as described in the present application addresses complications, such as contamination/cross-contamination, and is used to track fiber from bales of fiber processed into a textile product throughout a sequence of textile operations. The system captures, for each textile operation, a) input information, b) output information, and c) equipment information related to the equipment used in the textile operation. The output information is associated with the input information of a subsequent textile operation, thereby associating the input information and output information, for each textile operation, with the fiber information for the bales of fiber.

  • Patent number: 9465021
    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”.
