Ultrasonic sound
Ultrasonic sound refers to sound waves with a frequency greater than the upper limit of human hearing. Ultrasound has a variety of uses including medical imaging, detection, measurement, and cleaning. Bats, dolphins, and some animals can perceive ultrasound due to their ability to hear very high frequency sounds, which they use for echolocation and navigation. Detection and ranging applications of ultrasound include non-contact sensors, non-destructive testing, sonar for underwater range finding, and medical ultrasonography.
USES OF ULTRASOUND WAVES
This document discusses various uses of ultrasound waves. It begins by defining ultrasound as sound waves with a frequency above the human hearing range. It then lists 10 common uses of ultrasound, including for cleaning, disintegration, humidifiers, welding, weapons, and various applications in medicine like sonography and therapy. Each use is then discussed in more detail with explanations and examples. The document concludes that ultrasound has diverse uses across many fields like medicine, industry, and nature.
Basics of Ultrasound
Ultrasound uses high-frequency sound waves to produce images of the inside of the body in real-time without using radiation. It is widely used due to its availability, low cost, speed, and ability to show internal structures and blood flow. Common uses include examining organs like the heart, liver, and kidneys, as well as guiding procedures, imaging breasts and blood vessels, and assessing fetal development in pregnancies. The procedure works by a transducer sending sound waves into the body and receiving echoes to create images based on the return signal.

The ultrasonic generator converts the supplied alternating voltage of 50 Hz or 60 Hz to a frequency that corresponds to the operating frequency of the transducer.
The transducer then converts the released electric energy into mechanical acoustic oscillations causing the surrounding fluid to oscillate.
Each oscillation leads to an over-pressure phase or low-pressure phase in the fluid, depending on whether the transducer expands or contracts.
During the low-pressure phase, due to the fluid's limited tensile strength, small cavities form in the fluid; these so-called cavitation bubbles implode during the over-pressure phase.
When the cavitation bubbles implode at the surface to be cleaned, dirt particles are removIt is important at this stage to draw attention to the very important and significant difference between 6dBµV and 6dB. 6dBµV is another way of expressing a voltage measurement 0f 2µV. 6dB however is merely expressing a ratio – stating that one number is 6dB higher than another indicates that the first number has double amplitude of the second. So if the decibel is dimensionless, i.e it does not have a specific reference attached to it, then that decibel reading is not telling anything. To say this is double is quite meaningless without a reference – it must be double compared with something else.
It is very important to keep in mind that decibels should not be multiplied or divided. They are dB and should only be added or subtracted. To say for example that 36dBµV is twice as big as 18dBµV is in correct. The difference between these two values is 18dBµV which correspond to a ratio of 7.9. So the voltage amplitude of a signal of 36dBµV is not 2 times higher than the voltage amplitude of a signal of 18dBµV, its in fact, 7.9 times higher!
Lets apply this to the bearing:
In January, bearing “A” was measured with an ultrasound detector and the value was 10dBµV
In April, that same bearing measured 62dBµV.
62dBµV - 10dBµV = 52dBµV (factor of 400)
Therefore, from January to April, the ultrasonic signal from bearing “A” increased by a factor of 400 – probably the has already failed.

How to Manufacture Disposable Surgical Devices, Medical Products, Hospital Pr...
Medical and surgical device manufacturers worldwide produce a multitude of items that are intended for one use only. The primary reason is infection control; when an item is used only once it cannot transmit infectious agents to subsequent patients. Like medicines and other health technologies, they are essential for patient care – at the bedside, at the rural health clinic or at the large, specialized hospital. The demand of these goods is not only because of their “one time use” property but also due to the hygienic methods adopted to produce them. From manufacturing to Marking, production of disposable goods is stacked with numerous standards and regulations.

Like medicines and other health technologies, they are essential for patient care – at the bedside, at the rural health clinic or at the large, specialized hospital. The demand of these goods is not only because of their “one time use” property but also due to the hygienic methods adopted to produce them. From manufacturing to Marking, production of disposable goods is stacked with numerous standards and regulations.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Ultrasound
- 2. Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Although this limit varies from person to person, it is approximately 20 kilohertz (20,000 hertz) in healthy, young adults and thus, 20 kHz serves as a useful lower limit in describing ultrasound.
- 7. 1.Winding & Unwinding Ultrasound sensors are used to detect the changes in diameter of drums and reels as they are wound or unwound. Typical industries are: •Paper and Printing •Metal working •Textiles •Packaging •Plastics INDUSTRIAL APPLICATIONS
- 8. 2. Slope Control Ultrasonic sensors are used to monitor the slope of loops of material in a process. They are the sensing components of systems that control continuous running of flexible material. Typical industries are: •Paper and Printing •Chemicals •Textiles •Metal Working •Packaging INDUSTRIAL APPLICATIONS
- 9. 3. Height Measurement With high accuracy and repeatability, ultrasonic sensors are used to measure the height of objects that are moving past the sensor. Measurements are generally unaffected by surface finishes and shapes of the measured objects. Industries where this type of application are found include: •Automotive •Packaging and Distribution •Printing •Metal Working •Assembly •Agriculture INDUSTRIAL APPLICATIONS
- 10. 4. Position Control Pairs of ultrasonic sensors are used to accurately position objects. Linked together in a control system. the sensors provide the prime input for object location and position adjustment. Industries using these applications include: •Automotive •Packaging •Printing •Assembly •Robotics •Plastics INDUSTRIAL APPLICATIONS
- 11. 5. Collision Protection Ultrasonic sensors are attached to moving objects and equipment to provide collision protection. The sensor continuously relays proximity data to a controller. Many industrial users include: •Automotive •Automation •Logistics •Metal Working INDUSTRIAL APPLICATIONS
- 12. 6. Level Sensing Ultrasonic sensors have a unique ability to detect uneven surfaces and return accurate distance data. The sensors are used in many applications where the detection of the level of a fluid in a container is needed. Typical industries include: •Food and Beverage •Chemical •Water Treatment •Power Generation INDUSTRIAL APPLICATIONS
- 13. 7. Filing Sensing Ultrasonic sensors can accurately detect the changing levels of powders, grains and other semi fluid substances. Many industrial users include: •Agriculture •Chemicals •Packaging •Fluid Handling INDUSTRIAL APPLICATIONS
- 15. Biomedical ultrasonic applications •According to Radiology Info, ultrasounds are useful in the detection of pelvic abnormalities and can involve techniques known as abdominal (transabdominal) ultrasound, vaginal (transvaginal or endovaginal) ultrasound in women, and also rectal (transrectal) ultrasound in men. •Focused high-energy ultrasound pulses can be used to break calculi such as kidney stones and gallstones into fragments small enough to be passed from the body without undue difficulty, a process known as lithotripsy.
- 19. A common use of ultrasound is in range finding; this use is also called SONAR, (sound navigation and ranging). Ultrasonic range finding
