Abstract: The present invention discloses a cable force identification algorithm considering semi-rigid constraints on both ends. The present invention only needs the basic parameters such as length and mass per unit length of a cable and then adopts a modal identification algorithm such as stochastic subspace method and frequency domain decomposition method to process signals collected by the acceleration sensor, and thus obtains the corresponding first natural frequency and mode shapes, and the cable force can be solved without obtaining any other data in advance. The present invention simplifies the cable to an equivalent single-degree-of-freedom system, modifies the first natural frequency of the cable through the mode shape of modal identification, avoids the cable force identification error caused by the change of the boundary mechanical characteristics of the cable, improves the efficiency and accuracy of cable force monitoring, has good application prospect in real-time monitoring of cable force of cable-stayed structure.

Abstract: An environmental condition may be measured with a sensor (10) including a wire (20) having an ultrasonic signal transmission characteristic that varies in response to the environmental condition by sensing ultrasonic energy propagated through the wire using multiple types of propagation, and separating an effect of temperature on the wire from an effect of strain on the wire using the sensed ultrasonic energy propagated through the wire using the multiple types of propagation. A positive feedback loop may be used to excite the wire such that strain in the wire is based upon a sensed resonant frequency, while a square wave with a controlled duty cycle may be used to excite the wire at multiple excitation frequencies. A phase matched cone (200, 210) may be used to couple ultrasonic energy between a waveguide wire (202, 212) and a transducer (204, 214).

Abstract: A housing cladding module for a medical device is provided for collision identification. The module includes resistor elements, which are arranged in and/or on the surface and which are designed such that the resistor elements change their electrical resistance on expansion. The resistor elements are arranged in such a way that the resistor elements are expanded in the event of a collision with an object. The collision is identified easily, and the effective collision force may be ascertained.
