  • Tapered core fiber manufacturing methods
    Patent number: 9815731
    Abstract: Tapered core fibers are produced using tapered core rods that can be etched or ground so that a fiber cladding has a constant diameter. The tapered core can be an actively doped core, or a passive core. One or more sleeving tubes can be collapsed onto a tapered core rod and exterior portions of the collapsed sleeving tubes can be ground to provide a constant cladding diameter in a fiber drawn from the preform.
    Type: Grant

  • Instrumented Roller Bearing Device
    Publication number: 20100098362
    Abstract: The instrumented rolling bearing device comprises a rotating ring 5, a non-rotating ring 4, and a detection assembly 3 equipped with a sensor unit 11 comprising an external annular portion 11b and a means of axially retaining the sensor unit on the non-rotating ring positioned on the external annular portion 11b. The outside diameter of the external annular portion 11b is smaller than the inside diameter of a frontal radial surface 4b of the non-rotating ring.
