The acceleration-oscillogram method of motor-torque measurement

Electrical Engineering, 1942
The need for an improved method of measuring starting torque of large induction starting synchronous motors as compared to the power input and dynamometer methods, has led to the use of the acceleration oscillogram. A low ripple, permanent magnet type d-c generator is driven by the motor, and traces a time-speed oscillogram, from which acceleration ...

Wavelet frequency spectrum analysis of oscillograms

The Analyst, 1999
By combining wavelet transform with frequency spectrum analysis, wavelet frequency spectrum analysis of an oscillogram was achieved, based on the wavelet property of extracting useful information. Compared with Fourier frequency spectrum analysis of an oscillogram, this method presents many advantages.

Interpretation of the Speech Oscillogram

The Journal of the Acoustical Society of America, 1966
Due to the dynamic nature of sound, it is difficult to observe speech characteristics quantitatively by ear and make precise reproducible measurements unless of a rather coarse nature. However, we can stop the motion and obtain static measurable elements by taking pictures of the sound waves.

Analysis of Short-Circuit Oscillograms

Transactions of the American Institute of Electrical Engineers, 1941
METHODS of analyzing the oscillograms of short circuit currents of synchronous machines, in accordance with the two reaction theory, are presented in this paper. Differences between the results found here and the more generally accepted equations, based on symmetrical components, are pointed out.

Clinical investigation by the oscillogram of peripheral arteries

American Heart Journal, 1955
Abstract An analysis of the oscillograms (tracings of arterial oscillations) of the extremities of 127 subjects, both normal and diseased, is presented. Tracings were made with a specially constructed differential manometer based on the principles of the torsion-tension relationship of a twisted metal band, and utilizing an ordinary blood pressure ...

Breaker performance studied by cathode ray oscillograms

Electrical Engineering, 1935
Analyses of cathode ray oscillograms of circuit interruptions reveal characteristics of the circuits that are significant in the study of circuit breaker performance. While a complete analysis of such an oscillogram involves much detailed work, the study of several typical oscillograms reveals the significance of certain types of voltage variations and
