  • Patent number: 11002623
    Abstract: Tension monitoring is described using a sensor which may exhibit an offset for which compensation may be provided to produce a zero voltage amplified output or to increase dynamic range. An arrangement determines whether a power reset is responsive to a battery bounce such that an initially-measured system start-up parameter can be retained. The start-up parameter is automatically saved at start-up if the power reset is responsive to a start-up from a shut-down condition. The start-up parameter may be a zero tension amplified output responsive to the sensor offset at zero tension. Protection of a tension data set is provided such that no opportunity for altering the data set is presented prior to transfer of the data set. A housing configuration forms part of an electrical power circuit for providing electrical power to an electronics package from a battery.

  • Patent number: 10955323
    Abstract: To provide a method whereby viscoelasticity of an object can be measured nondestructively and in non-contact fashion in a short time. By this method, elastic waves and light are radiated to an object and the viscoelasticity of an object is measured nondestructively and in non-contact fashion using a shadow change based on a change in the direction of a line normal to the surface of the object. Specifically, the present invention has an elastic wave transmission step for pressurizing or exciting the object by elastic waves and causing a minute displacement of the object surface shape, a photoirradiation step for radiating light to the minutely displaced object surface, an image acquisition step for acquiring a shadow change based on a change in the direction of a line normal to the object surface, and a viscoelasticity estimation step for processing an image of the acquired shadow change and calculating a viscoelasticity.
