Measurement of total ultrasonic power using thermal expansion and change in buoyancy of an absorbing target.
The Radiation Force Balance (RFB) technique is well established and most widely used for the measurement of total ultrasonic power radiated by ultrasonic transducer. The technique is used as a primary standard for calibration of ultrasonic transducers with relatively fair uncertainty in the low power (below 1 W) regime. In this technique, uncertainty comparatively increases in the range of few ...
متن کاملUltrasonic Power Output Measurement by Pulsed Radiation Pressure
Direct measurements of time-averaged spatially integrated output power radiated into reflectionless water loads can be made with high accuracy using techniques which exploit the radiation pressure exerted by sound on all objects in its path. With an absorptive target arranged to intercept the entirety of an ultrasound beam, total beam power can be determined as accurately as the radiation force...
متن کاملMulti-output Portable Universal Power Supply Kit with Plug-and-Use Equipment for Emergency Application
This paper presents design and analysis of Multi-output Portable Universal Power Supply Kit (EPS Kit). This EPS Kit is intended as an alternative power supply kit to reduce the issue of a power outage. Lead Acid Battery which is considered one of the easiest sources that can be found during an emergency state is the best alternative energy source. The EPS Kit is designed to store the power in L...
متن کامل[The development of ultrasonic diagnostic equipment for dental use].
When a dentist prepares a vital tooth, it is very important to know the distance between the prepared surface and the pulp chamber wall, and now we have developed ultrasonic diagnostic equipment which can indicate the nearness of these two boundaries by measuring the thickness of the remaining dentin. This equipment can be used to measure the thickness of the remaining dentin between the prepar...
متن کاملA simple and novel method for acoustic streaming power measurement of ultrasonic horn
Ultrasonic horn with transfer of acoustic wave into an aqueous solution results in unique properties. When, transfer of sound wave into a liquid results in liquid movement in the direction of wave propagation which gradually loses its energy due to the viscous friction. This wave motion induces a flow which is known as acoustic streaming or micro-streaming. In this article, a simple innovative ...
