  • Patent number: 11714145
    Abstract: Methods for forming conformal magnetic resonance imaging (MRI) receive coil devices having at least one receive coil with at least one capacitor are provided and include providing a 3-dimensional (3D) mold structure matching a curvilinear shape of interest, and forming a receive coil pattern on an outer surface of the 3D mold structure. The forming of the receive coil pattern may include spraying and/or depositing a conductive material and a dielectric material on the outer surface of the mold structure to form the receive coil pattern. The forming a receive coil pattern may include forming the receive coil pattern on an outer surface of a flat substrate sheet, and vacuum forming an inner surface of the flat substrate sheet to the outer surface of the mold structure to form a shape-conforming substrate sheet. The shape-conforming substrate sheet may be removed from the mold and used in MRI studies.

  • Publication number: 20220074089
    Abstract: A system for treatment of thread includes a weft thread printer having an intake positioned to receive a weft thread from a source, as well as an encoder that is configured to detect a length of the weft thread as the weft thread moves through the weft thread printer along a travel path. The system also includes a printhead positioned to apply coatings of a plurality of colors to the weft thread and yield a treated weft thread, as well as an outlet positioned to pass the treated weft thread to a loom.

  • Patent number: 10688808
    Abstract: A system and method for treatment of thread includes a thread printer that applies colored coatings to thread. A camera is positioned to capture images of the treated thread after it passes through an outlet of the thread printer. The system processes the images to determine whether the location of a selected segment of the treated thread corresponds to an expected location. If the actual location of the selected segment corresponds to the expected location, the system will continue instructing the thread printer to selectively apply the colored coatings to the thread according to the pattern. However, if the actual location does not correspond to the expected location, the system will modify the pattern so that thread printer adjusts the size of one or more segment to automatically account for the misalignment.

  • Patent number: 10525734
    Abstract: A system and method for treatment of thread includes a thread printer that applies colored coatings to thread and that passes the treated thread to a fabric weaving system. A camera is positioned to capture images of the treated thread as it is woven into a fabric in the fabric weaving system. The system processes the images to determine whether the location of a selected segment of the treated thread in the fabric corresponds to an expected location in the fabric. If the actual location of the selected segment corresponds to the expected location, the system will continue instructing the thread printer to selectively apply the colored coatings to the thread according to the pattern. However, if the actual location does not correspond to the expected location, the system will modify the pattern so that thread printer adjusts the size of a segments to automatically account for the misalignment.
