  • Method and apparatus for removing flash from a tire
    Patent number: 9833931
    Abstract: An apparatus for removing flash from a tire includes a laser sensor which, while the tire is rotating, can be moved along the outer contour of the shoulders and tread area of a tire to detect the contour of the tire. A first sanding assembly removes the flash from the tread area, while the tire is not rotating, by moving horizontally and vertically in accordance with the detected contour of the tread area. A second sanding assembly removes the flash from the shoulder area, while the tire is rotating, by moving horizontally, vertically, and pivotally in accordance with the detected contour of the shoulder area.

  • Method and system for circuit board common mode noise suppression utilizing ferrous cores
    Patent number: 6089917
    Abstract: A noise attenuating system for suppressing noise on circuit board transmission lines is provided. A first ferrous member is attached to a first side of the circuit board and a second ferrous member attached to a second side of the circuit board. The second ferrous member is substantially opposed from the first ferrous member, such that conductive transmission lines are contained between the first ferrous member and the second ferrous member. Transmission line interference is absorbed and suppressed by the first ferrous member and the second ferrous member. In a preferred embodiment, substantially all traces which enter and exit the circuit board on a connector pass between the first ferrous member and the second ferrous member. Apertures in the circuit board allow the ferrous members to adjoin forming a ferrous core.
