For single channel sound velocity measurement system accuracy was generally not high,a high-precision dual-channel sound velocity of seawater measurement system was designed.Based on ultrasonic speed of sound measurement in seawater with time-of-flight method,the system used ARM microcontroller to combine with high-precision time interval measurement chip,and the sound velocity measurement was translated into distance and time measurement. Then the influence of the time delay of the system was eliminated by method of difference.The paper introduced the modules of the system,and the high-precision time interval measurement method as the key technology of time-of-flight method for the velocity measurement system was expounded.It wasproved by experiment that the measurement accuracy of the system on the velocity reached 0.019m/s.

This paper describes a time-interval measurement system with increased resolution using multiple taped delay lines. In this time-interval measurement system, sixteen time-stamps are registered during a single measuring cycle (one shot). It means that the value of the measured time-interval can be interpolated with higher resolution without increasing the number of measurements or the interpolation time. Limiting the total measurement time reduces the energy consumption which is particularly important in battery powered systems.

Time Interval Measurement

The purpose of this study was to determine whether accuracy training for interval judgments of stuttering might generalize to increased accuracy and/or interjudge agreement for intervals other than those used during training. Ten upper-division speech-language pathology students judged 5-s audiovisually recorded speech intervals as stuttered or nonstuttered in a series of group and single-subject experiments. Judgment accuracy was determined with respect to judgments provided previously by 10 recognized authorities on stuttering and its treatment. Training occurred within single-subject experiments that used multiple baselines across speakers and repeated generalization probes to assess training effects. Results showed that judgment accuracy tended to increase after training for speakers used during the training process as well as for unfamiliar speakers. Results also replicated previous findings of slight increases in interjudge and intrajudge agreement after interval-judgment training. The implications of these results for developing a valid and reliable stuttering measurement system are discussed.
