Recent accounts of ultrasonic flowmeters usually concentrate on either transit time or Doppler types. Although these are the most common types in use today, at least six other types exist. Part 1 of this two-part paper describes the physical principles of eight types of ultrasonic flowmeters, along with some general considerations (flow profile ...

Ultrasonic masker clarifies ultrasonic perception in man
Hearing Research, 2003Bone conduction enables ultrasound to be heard. Although several hypotheses about ultrasonic perception have been presented, the perception mechanism of bone-conducted ultrasound has not yet been established. In this study, to investigate ultrasonic perception, the amount of masking produced by 27-, 30- and 33-kHz bone-conducted ultrasonic maskers for ...

Ultrasonic Visualization of Ultrasonically Produced Lesions in Brain [PDF]
Stereotactic and Functional Neurosurgery, 1970 Three anatomically discrete, ultrasonically produced brain lesions in the rhesus monkey have been visualized ultrasonically in the immediate post-lesion period, as well as three weeks later. After sacrifice at three weeks, the histologically prepared brain sections in the lesion area have been compared with the echogram information to verify lesion ...

Journal of Clinical Periodontology, 1974
Abstract The vibrating tips of ultrasonic instruments have been shown to remove deposits mechanically. Calculus removal is equally effective with ultrasonic or hand instruments, whereas stain removal has been shown to be better with the former. It has been observed that ultrasonic instruments remove heavy supragingival calculus faster than hand ...
