A performance measuring system for a rotating shaft comprises a first annular support assembly to be coupled adjacent to a first end of a rotating shaft inwardly of associated shaft bearings. A second annular support assembly is to be coupled adjacent to a second end of a rotating shaft inwardly of
A performance measuring system for a rotating shaft comprises a first annular support assembly to be coupled adjacent to a first end of a rotating shaft inwardly of associated shaft bearings. A second annular support assembly is to be coupled adjacent to a second end of a rotating shaft inwardly of associated shaft bearings. A third annular support assembly is to be coupled to the rotating shaft between the first and second support assemblies. A laser source is mounted on the first annular support assembly. A laser detector is mounted on the second annular support assembly. First and second magnetic sensors for detecting the Earth's magnetic field are mounted respectively on the first and second annular support assemblies. An accelerometer is mounted on the third annular support assembly for generating a fourth detection signal.

A dynamic quantity sensor comprising: a base portion; a spring portion for moving in a predetermined direction in accordance with a dynamic quantity applied thereto, the spring portion being provided above the base portion; a movable portion connected to the spring portion for moving together with the spring portion in the predetermined direction; a movable electrode integrated with the movable portion for moving together with the movable portion; and a fixed electrode supported by the base portion and arranged opposite to the movable electrode while defining a detection interval, a change of which caused by displacement of the movable electrode is detected to detect the dynamic quantity, wherein: a Q value of vibration of the movable portion in the predetermined direction is smaller than 1/500 of a resonance frequency of the vibration of the movable portion in the predetermined direction. 7. The dynamic quantity sensor according to claim 6, wherein: a resonance frequency of the spring portion is less than a resonance frequency of the movable electrode to thereby ensure sensor output accuracy. 8. The dynamic quantity sensor according to claim 6, wherein: the spring portion is comprised of a beam portion having a rectangular frame shape; and a width of the movable electrode is approximately equal to a width of the beam portion. 0; US-5415033, 19950500, Maresca, Jr. et al., 073/040.5; US-5425266, 19950600, Fournier, 073/049.7; US-5448980, 19950900, Kawamura et al., 123/520; US-5507176, 19960400, Kammeraad et al., 073/049.2; US-5524662, 19960600, Benjey et al., 137/043; US-5564306, 19961000, Miller, 073/861; US-5579742, 19961200, Yamazaki et al., 123/520; US-5584271, 19961200, Sakata, 123/188.6; US-5603349, 19970200, Harris, 137/588; US-5614665, 19970300, Curran et al., 073/118.1; US-5635630, 19970600, Dawson et al., 073/040.5; US-5644072, 19970700, Chirco et al., 073/049.2; US-5671718, 19970900, Curran et al., 123/520; US-5681151, 19971000, Wood, 417/307; US-5687633, 19971100, Eady, 092/097; US-5692474, 19971200, Yamauchi et al., 123/406.22; US-5743169, 19980400, Yamada, 092/100; US-5859365, 19990100, Kataoka et al., 073/149; US-5893389, 19990400, Cunningham, 137/516.27; US-5894784, 19990400, Bobbitt, III et al., 092/100; US-5979869, 19991100, Hiddessen, 251/285; US-6003499, 19991200, Devall et al., 123/520; US-6073487, 20000600, Dawson, 073/118.1; US-6089081, 20000700, Cook et al., 073/118.1; US-6131448, 20001000, Hyodo et al., 073/118.1; US-6142062, 20001100, Streitman, 092/099; US-6145430, 20001100, Able et al., 092/093; US-6168168, 20010100, Brown, 277/637; US-6202688, 20010300, Khadim, 137/599.08; US-6203022, 20010300, Struschka et al., 277/572; US-6328021, 20011200, Perry et al., 123/518; US-6401698, 20020600, Yamazaki et al., 123/529
