Material Sensing Patents (Class 112/475.02)
  • Patent number: 9051671
    Abstract: A bobbin thread monitor includes a rotatable thread pulley together with a rotation sensing counter and numeric count display. During bobbin loading, the thread supply is looped about the pulley in a first direction resulting in rotation of the thread pulley in a corresponding first direction. The rotation of the thread pulley in the first direction produces an accumulated account within the rotation sensing and display apparatus. During sewing operations, the thread supply is looped about the thread pulley in a second opposite direction loop resulting in opposite direction rotation of the thread pulley during the sewing process. The opposite direction rotation of the thread pulley during the sewing process produces a downcount of the number accumulated during the bobbin loading process. This down count is indicative of bobbin supply remaining and may be used to activate additional alarm apparatus.

  • Publication number: 20120312213
    Abstract: A device controls the speed of needle movement in a sewing machine and thus the stitch length based upon the movement of a motion detection device relative to a reference surface. The formation of stitches by the sewing machine is controlled by detected changes in position of the detection device relative to the reference surface in connection with a predetermined stitch length setting and starting speed, set on either the detection device, an adapter or as part of the sewing machine control. The detection device may move together with the article being sewn while the sewing machine and reference surface remain stationary, or the detection device may move with the sewing machine while the article that is being sewn and reference surface remain stationary.
