From: http://en.wikipedia.org/wiki/High-intensity_focused_ultrasound ADH(High-Intensity Focused Ultrasound) (SometimesFUSOrHIFUS) Is a highly precise medical procedure using high-intensity focused ultrasound medical device to heat and destroy pathogenic tissue rapidly. it is one modality of therapeutic ultrasound, and, although it induces hyperthermia, it shosho

In the past, B-Ultra just walked into the county hospital, doctors often encountered such things: (County doctor) had to have a boy, have to see also, in the early days there are crying let us a identification of fetal sex, we say this is the law can not identify fetal sex, most can understand. We are in the home of the "mother-Child Law" strict regulations, prohibit the use of B-ultrasound to identify the sex of the fetus. Except for some genetic dis

Let's look at a simple example:Code snippet 1: public class Container { public void init() { Speaker s = new Speaker(); Greeting g = new Greeting(s); } } We can see that the Container class (Container) will gene

Audio is a very important element in information transmission, and even a good play without sound is also useless. Therefore, audio technology has been paid attention to during the development of TV. However, compared with the image progress, audio technology development lags behind, so the audio industry workers should work hard. Skyworth A12 audio Engine Technology Skyworth has A12 audio engine technology on LCD TV audio, and challenged Hisense, which is dominant in the Chinese mark

Psychological acoustics This paper studies the relationship between subjective hearing and physical quantity of sound. It focuses on the relationship between sound stimulation and response. People's correct feeling and comprehension of sound are very important to the Evaluation of sound. Phase When the phase difference between two sound signals is equal to O, two States are specified in the audio system: one is that when two (or more) Speakers input the same signal, the vibration direction

Zheng Yi 20091119 Dongye often adds all kinds of knowledge points to his reasoning novels, so that you can enjoy his strict logical reasoning and get popular science. Two examples have been given above, such as the P/NP problem in "the dedication of the Suspect X", and the Monroe Effect in the predicate of the series "probe Galileo. Therefore, it is strongly recommended that science and technology students read the reasoning novels of dongqiawu and click here to package and download his 21 nov

vibration detection with piezoelectric elements This example shows you how to use a piezoelectric element to detect vibrations. (The piezoelectric element has many kinds of applications, the buzzer is one kind, but here is not "forward" uses the piezoelectric element, but uses its circuit characteristic "the reverse" uses. That is, the power generated vibration, vibration sound, now is the vibration generated current, judging by the current vibration. This example shows you how to use a piezoel

What are the best professional stage audio brands?First, the American speaker brand1, the Sound/polkaudio (is the world famous audio manufacturing company, one of the world's largest speaker manufacturers, with 65 patents above, the United States brand)2, Dr. Bose (American brand, founded in 1964, one of the world's first loudspeaker companies)3. JBL (American brand, world famous old

Ultrasonic Ultrasonic (Waves): The frequency at which human ears can hear is 20hz~20khz. When the vibration frequency of sound waves is greater than 20KHz or less than 20Hz, we can not hear. Therefore, we refer to sound waves that are above 20000 Hz as "ultrasound". Because of its good directivity, penetrating ability, easy to obtain a more concentrated sound energy, in the water spread far away, can be used for ranging, speed, cleaning, welding, grav

ASP. NET reflection, Two examples in reality:1. B-ultrasound: You probably have performed B-ultrasound during the health check. B-ultrasound can detect the physiological status of your internal organs through your belly. How is this done? B-ultrasound is a B-type ultrasound.

The line connection of the home theater is centered on the AV Power Amplifier. Its input end is connected to signal sources such as DVDs, CDs, and satellite receivers through a signal line. Its output end is connected to speakers, televisions, and projectors. Currently, the speaker system of the home theater system is generally dominated by 5.1. The connection diagram is as follows: As shown in, the two main speakers of the 5.1

someone sends a message asking "Where are you", Hangouts will automatically pop up a bubble and let people share the location directly to each other.EMU will also affect other Google products, such as Inbox, can also be directly based on the content of the mail, automatically provide geolocation, OpenTable, Yelp and other services. Copresence, cross-platform ultrasound pairing Google is developing an

The achievable accuracy for systems and multiple ADCs depends directly on the reference voltages applied to the ADCs. Medical-ultrasound-imaging systems, for example, commonly include a large number of ADCs in the system ' s Beam-former elect Ronics, with the ADCs usually organized in groups of--- To obtain maximum beam accuracy, you must minimize errors in the ADC path. Poor accuracy of the reference voltages of the individual ADCs degrades the overa
