20150075691 | TYRE AND EXTENDED-MOBILITY WHEEL-TYRE ASSEMBLY - A tyre has a form of a torus that is open radially on an inside portion. The tyre includes inner and outer walls, a crown, two sidewalls, two beads, a crown reinforcement, and a carcass reinforcement anchored in the beads and extending at least from the beads as far as the crown. The inner wall is covered at least in part with an airtight layer, and the airtight layer is covered at least in part with a layer of a self-sealing product. Each of the beads includes an annular reinforcing structure, with each annular reinforcing structure being formed of a plurality of windings of a single metal thread. The windings are arranged in a plurality of radially superposed layers, with each layer having a group of the windings arranged axially in a side by side manner, such that the superposed layers have a hexagonal cross section. | 03-19-2015 |
20140326062 | SYSTEM AND METHOD FOR DETERMINING TIRE UNIFORMITY PARAMETERS FROM PIEZOELECTRIC MEASUREMENTS IN THE TIRE COUNTER-DEFLECTION ZONE - Systems and methods of determining tire uniformity parameters from piezoelectric tire sensor output signals obtained while operating in the counter-deflection zone include establishing a transfer function that relates a tire uniformity parameter to the piezoelectric output signals. Piezoelectric output signals from two or more piezoelectric tire sensors are then monitored to measure the voltage change from each piezoelectric tire sensor while it is operating in the counter-deflection zone. These output signals are correlated, and an actual tire uniformity parameter value is determined by applying the measured and correlated piezoelectric output signal voltage change levels to the established transfer function. Actual tire uniformity values are ultimately provided as electronic output to a user. | 11-06-2014 |
