  • Publication number: 20240159665
    Abstract: A method for detecting a contaminant. A Fourier transform infrared scan for a section of the unconsolidated composite material is received in real time during manufacturing of the unconsolidated composite material by a composite material manufacturing system. A determination is made as to whether a contaminant is present in the section of the unconsolidated composite material in real time during manufacturing of the unconsolidated composite material by the composite material manufacturing system using the Fourier transform infrared scan and a machine learning model system trained to classify contaminants in unconsolidated composite materials using the Fourier transform infrared scan of the unconsolidated composite materials.

  • Publication number: 20240153063
    Abstract: A method, apparatus, system, and computer program product for detecting inconsistencies in an unconsolidated composite material. Fiber inconsistencies are detected in sections of the fibers input into a composite material manufacturing system in real time during operation of the composite material manufacturing system. Material inconsistencies are detected in the unconsolidated composite material in real time as the unconsolidated composite material is being manufactured by the composite material manufacturing system using the fibers. A determination is made as to whether the material inconsistencies are present in a number of the sections in which the fiber inconsistencies are detected in real time as the unconsolidated composite material is being manufactured by the composite material manufacturing system.

  • Patent number: 11943876
    Abstract: Pre-connected analyte sensors are provided. A pre-connected analyte sensor includes a sensor carrier attached to an analyte sensor. The sensor carrier includes a substrate configured for mechanical coupling of the sensor to testing, calibration, or wearable equipment. The sensor carrier also includes conductive contacts for electrically coupling sensor electrodes to the testing, calibration, or wearable equipment.

  • Patent number: 4727917
    Abstract: An off-the-highway vehicle tire employing long and short lugs alternately disposed about the periphery in a substantially symmetric manner whereby lugs from each side of the tire strike the ground substantially simultaneously thereby minimizing side forces.

  • Patent number: 4645486
    Abstract: This invention relates to a "plungerless" means of drawing blood and for administering liquids via parenteral injection. This means is used in conjunction with a pouch bearing an injection means, to which it is releasably attached. It comprises hinged plates which, when folded, expand the pouch; and which, when straightened, compress it.In a preferred embodiment, the plates fold along a line essentially parallel to the general direction of fluid flow, and extend beyond the distal end of the pouch. The expanded pouch may then be rested on the distal edges of the plates, which form a "diamond" configuration.
