Abstract: This system comprises: at least one vibrational sensor which is operable to produce data each time an impact application device applies an impact from a user to the prosthetic component during assembly between the prosthetic component and with the support member, the produced data representing acoustic vibrations generated in the air and/or material vibrations generated in the impact application device, an analysis unit which is configured both to calculate a frequency characterization of the vibrations for each impact applied by the impact application device to the prosthetic component, from the corresponding data produced by the at least one vibrational sensor, and to compare the frequency characterizations that are respectively calculated for successive impacts so as to provide at each of the successive impacts either a first indication when the assembly between the prosthetic component and the support member is not fully seated or a second indication when the assembly between the prosthetic component and the support member is fully seated, and a user interface which provides feedback to the user based on the first and second indications.

Abstract: A detection system for identifying deterioration in a structure is provided that has acoustic sensors that receive acoustic emission waves. The acoustic emission wave detected by the acoustic sensor is identified as a hit. An analysis circuit is present that identifies an A state, a B state, and a C state. The B state has increased hit activity from the A state where a rate B is greater than a rate A by a factor of f1. The C state has increased hit activity from the B state where a rate C is greater than the rate A by a factor of f2. An alarm is activated when an amount of time that the C state is identified as being present reaches a value of TM, or alternatively when a threshold value based upon of the number of hits and time in the C state is reached.

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: A sensor for detecting stress waves for use in a stress wave analysis system. The stress waves are preferably detected in a narrow frequency range of 35-40 KHz. At this range, stress waves from friction and impact sources typically propagate through machine structures at detectable amplitudes. In order to maximize the signal to noise ratio of stress waves, relative to background noise and vibration, the sensor of the present invention is designed and calibrated with a frequency response and damping features that are specifically tailored for stress wave analysis. The sensor is a multi-functional sensor that can measure a number of logically related parameters for indicting the mechanical condition of a machine. It is often desirable to measure both friction and one or more other parameters appropriate for indication of a machine's health, where all of the measuring capability is contained in one sensor. The multi-functional capability of the present invention significantly reduces the acquisition, installation, and maintenance costs of the condition monitoring instrumentation system.
