  • Method for increasing the position measurement accuracy using inductive position sensor
    Patent number: 11293744
    Abstract: An accurate position sensor that operates over a long range is provided. The position sensor can include a first sensor coil having a first number of periods over a range of motion of a target; and a second sensor coil having a second number of periods over the range, wherein the first number of periods is different from the second number of periods, and wherein the first sensor coil and the second sensor coil are arranged with respect to one another such that the target engages both of them simultaneously. In some embodiments, the first number of periods is one and the second number of periods is greater than one. In some embodiments, the first number of periods is greater than one and the second number of periods is greater than the first number of periods.

  • Device and method for adjusting hosiery tension in circular textile machines
    Patent number: 6339943
    Abstract: A device for the electronic adjustment of hosiery tension in circular textile machines, whose particularity consists of the fact that it comprises an actuator which is adapted to move a carriage, which is in turn adapted to perform a translatory motion along an axis which is parallel to a diametrical axis of the circular textile machine, the carriage supporting at least one transducer connected to a hosiery advancement device, the transducer being adapted to detect a contrasting force which is due to the advancement of the hosiery item, the contrasting force being processed in a controller which is adapted to emit a speed signal for the actuator, in order to adjust the movement speed of the carriage in contrast with the contrasting force.
