    Abstract: Transducer devices employing relative changes in the acoustic propagation characteristics of waves of the Rayleigh type flowing along polished surfaces of a thin elastic member yield a measure of the degree of flexing or surface strain of the elastic member, which latter may take the form, for instance, of a cantilever beam. Signal processing circuits supply outputs proportional to strain and free of mode locking and other spurious interactions of oscillatory circuits that include the surface wave delay elements.

    Abstract: A mechanical force measurement system is for measuring a force onto an object. The measurement system includes a sound wave generator which is adapted to generate a solid borne sound wave signal within the object. The system further includes a first sound wave receiver which receives a first solid borne sound wave signal based on the solid borne sound wave signal generated within the object by the sound wave generator. In order to compare a phase of the generated solid borne sound wave signal and a phase of the first received solid borne sound wave signal, and to generate a comparison signal based thereon. The system also includes a comparator unit. An evaluation unit of the system determines the mechanical force based on a data base and the comparison signal. The data base has stored a relation of a mechanical force and a comparison.

    Abstract: In the present disclosure, embodiments including a system, device and methods are disclosed for accurately measuring the strain or extension of a fastener that occurs as the nut on the fastener is tightened and the fastener is put under load. The measurement technique is based on measurement of the time for an ultrasonic wave generated on one end of the fastener to travel a round trip through the fastener. As the fastener is tightened, the applied stress causes an associated increase in length. This length can be determined from a measurement of the increase in transit time. In various embodiments, the disclosed device and method uses laser ultrasonic testing (LUT), in which a pulsed laser generates the ultrasonic wave and a type of laser vibrometer detects the wave when it returns to the position of generation following a combination of longitudinal wave reflections and a mode conversion to a shear wave.

    Abstract: A distractor suitable for measuring a force, pressure, or load applied by the muscular-skeletal system is disclosed. An insert couples to the distractor. The insert has at least one articular surface allowing movement of the muscular-skeletal system when the distractor is inserted thereto. The insert can be a passive insert having no measurement devices. A sensor array and electronics are housed within the distractor. The distractor can dynamically distract the muscular-skeletal system. A handle of the distractor can be rotated to increase or decrease the spacing between support structures. The measurement system comprises a sensor array and electronic circuitry. In one embodiment, the electronic circuitry is coupled to the sensor array by a unitary circuit board or substrate. The sensors can be integrated into the unitary circuit board. For example, the sensors can comprise elastically compressible capacitors or piezo-resistive devices. The distractor wirelessly couples to a remote system for providing position and magnitude measurement data of the force, pressure, or load being measured.
