Ultrasonic

Acoustic resonance principle Built into the cavity is an array of ultrasonic transducers, which are used to create the separate standing-wave patterns at ultrasonic frequencies.

The principle behind a pulsed-ultrasonic technology is that the transmit signal consists of short bursts of ultrasonic energy.

Ultrasonic actuators are designed to produce movements in a micrometer order at ultrasonic frequencies (over 20 kHz).

Ultrasonic force Ultrasonic Force Microscopy (UFM) has been developed in order to improve the details and image contrast on "flat" areas of interest where AFM images are limited in contrast.

Ultrasonic time-domain reflectometers (which send an ultrasonic pulse through a material and measure reflections from discontinuities) could find flaws inside cast metal and stone objects, improving structural safety.

Ultrasonic welding In ultrasonic welding of plastics, high frequency (15 kHz to 40 kHz ) low amplitude vibration is used to create heat by way of friction between the materials to be joined.

And as others have said, this is all eliminated by a firmware update that filters out ultrasonic frequencies.

Crane ultrasonic humidifier for around $39-$48.

Doctors then direct ultrasonic energy through a targeted pinpoint in the skull to the globus pallidus, a structure deep inside the brain that helps control voluntary movement.

Nvidia was developing the software, while Valeo was providing ultrasonic sensor hardware in the collaborative project for an unnamed automotive parts manufacturer.

Of course, humans can’t hear it normally, as the noise is ultrasonic and too high-pitched, so the scientists lowered the frequency until they managed to pick up the peculiar sound.

R92 Restorations, set up by Carl Robson, is based in Hexhamshire and will offer vapour blasting and ultrasonic cleaning as some of its main services.

The necklace was fresh from a cleaning — an ultrasonic water bath, followed by a steam — and visiting the office of the jewelry designer Alex Moss in late January en route to its owner: the rapper and singer Drake.

Future buyers can expect Qualcomm's latest Snapdragon 8 Elite processor with tons of RAM, the second-generation BOE X2 display, fancy new 6,000 mAh silicon-carbon battery, and an ultrasonic fingerprint sensor.

In addition to ultrasonic testing, magnetic particle inspection can be used to identify surface and slightly subsurface cracks.

It also comes with a 1,400 lux LED lamp, an ultrasonic dog whistle for search and rescue applications, and a Morse code-programmed SOS beacon.

It’s a technique that offers several advantages over conventional testing methods, such as ultrasonic and radiographic testing.

MANILA, Philippines — A group of students from the Quezon City Science High School have developed a device that can remove algal blooms in water bodies using ultrasonic radiation.

The cordless mower comes with detachable lithium-ion batteries and utilises a grass recognition camera and ultrasonic sensors, eliminating the need for a boundary wire, outdoor power socket or app, according to Chronicle Live.

These extraterrestrials have ultrasonic hearing and kill without hesitation.
