  • Method for measuring tension state of a material and uses thereof
    Patent number: 7010435
    Abstract: A method for determining the state of tension of a material at a given time, including the step of calculating the value of at least one parameter extracted from the ultrasonic signal received after propagation of an ultrasonic wave emitted in the material between an ultrasound source and at least an ultrasound emitter located at a fixed distance from the source, the value of the at least one parameter varying with the state of tension of the material, the variation of the at least one parameter being proportional or inversely proportional to the variation of the state of tension of the material.

  • Method for measuring tension state of a material and uses thereof
    Publication number: 20040249580
    Abstract: Method to determine the tension condition of a material at a given time, comprising one step during which one calculates the value of at least one parameter extracted from the ultrasonic signal received after propagation of an ultrasonic wave transmitted in said material between an ultrasound source and at least one ultrasound transmitter situated at a fixed predetermined distance from said source, the value of the parameter(s) varying with the tension condition of the material, said variation of the parameter(s) being proportional or reversely proportional to the variation in the tension condition of said material.
