Your lungs are healthy: When it blows on your phone
Today, patients with chronic lung diseases such as cystic fibrosis or asthma have been inconvenient to monitor their respiratory tracts. Instead, they have a special device called a spirometer because they can go to the doctor's office for testing. Therefore, in the past two years, graduate students at the University of Washington in Seattle have been working on developing an application that accurately measures lung function, but it requires additional hardware, and the hardware of existing applications is entertainment. In other words, they have been working hard to put spirometers in smart phones. Now, researchers in electrical engineering and computer science have published their SpiroSmart app, which is a portable spirometer that they tested on 52 "mostly healthy" volunteers. Basically, the researchers simulated the tubes of the human trachea and vocal tract system, which can replace the traditional spirometer and use the iPhone4S's microphone to analyze the frequency of sound waves. The researchers wrote on the SpiroSmart website: Through analysis of lip reverberation, we were able to monitor lung diseases such as asthma, chronic obstructive pulmonary disease, cystic fibrosis, and more. The team has received funding from the Kurt Foundation and conducted more clinical trials from patients. A simple and fun game on the phone, I believe users will not mind playing it at regular intervals.
The cutting machine is suitable for the cutting of Chinese medicinal herbs including rhizomes,fruitages,leaves,and grasses etc before it being fine processed,grinded or extracted,as well as for the cutting process of foodstuff(sliced fruit,preserved fruit),aquatic products(sliced kelp),tobacco leaves,and tea leave etc.This slicing machine is composed of motor, variable speed mechanism, tool rest, step and retreat material, adjustable tool rest machinery and so on. Due to the use of advanced step feeding, so that the cut of the sheet shape uniform, can freely control the feeding distance, will not cause the material extrusion knife bad situation. Due to the reasonable layout, the machine is easy to operate, light appearance, light weight. This machine is mainly composed of two parts, such as conveying and cutting medicine, machinery and so on.
