The commonly used computer camera interface is the USB interface, while the cameras on ordinary smartphones are MIPI interfaces, and some cameras are DVP interfaces; in layman's terms, USB is a serial universal serial bus,mipi camera manufacturer， MIPI is a mobile industry processing DVP is a digital video port.


The MIPI interface has fewer signal lines than the DVP interface. Because it is a low-voltage differential signal, the interference generated is small, and the anti-interference ability is also strong.


The PCLK of the DVP bus is limited to about 96M, and the trace length should not be too long. The maximum rate of all DVPs is best controlled below 72M, and the PCB layout is easier to draw. Therefore, the requirements for PCB routing and impedance control are higher.


On top of that, DVP interfaces are limited in terms of signal integrity and speed. 500W can barely use DVP, 800W and above all use MIPI interface.

Silica gel is an amorphous substance with stable chemical properties, non-toxic and harmless, no allergic reaction, insoluble in water and any solvent, and will not change its original elasticity and softness in contact with other tissues. silicone bottle brush，It is not easy to melt in a high temperature environment, which also lays the foundation for future use.


For example, for rhinoplasty, the prosthesis is made of silicone, which is not easy to deform. In breast augmentation, it is also made of silicone, and the softness is not easy to change. Generally speaking, the biggest advantages of silica gel are good adsorption, good heat resistance and good insulation. It is because of these properties that it is used as a desiccant and adsorbent.


High heat resistance, no change in performance under high temperature environment, so it is used as a sealing ring for electrical appliances, which is non-toxic and tasteless when heated.

Electronic cigarettes are called "substitutes" by merchants, which can restore the real taste of cigarettes. So what is the working principle of electronic cigarettes?


An electronic cigarette is an electronic product that mimics a cigarette and has the same look, smoke, taste and feel as a cigarette.electronic cigarette ， The working principle of the electronic cigarette is that the electronic cigarette atomizer operates the battery through the airflow sensor or the button, connects the atomizer, heats and evaporates the e-liquid, and produces an atomization effect, which achieves a similar effect to smoking.


According to reports, there are currently two main products in the Chinese market, collectively referred to as electronic cigarettes. One is a heat-not-burn product belonging to a new type of tobacco, and the other is an electronically atomized cigarette. In my country, heat not burn products belong to tobacco products and belong to the tobacco monopoly system. As a result, pods for products like IQOS cannot be sold in China. The only real electronic cigarette on the market is the vaping cigarette
