Not long ago, Apple released a new MacBook Pro with only one Thunderblot interface, and also removed the SD card slot, which made many users crazy. It should have been expected that Apple has explained a lot of the decisions behind it and is confident in this choice, although the user may not agree. In an interview with the Independent, Apple executive Phil Schiller said that the reason for removing the SD card slot is that it is a burden, and the wireless transmission technology on the camera is already a good alternative. His original words are: "There are several reasons. First, it is very cumbersome, always half-out (not good-looking). And there is a very good USB card reader on the market, you can also use the SD card. This problem is difficult to solve, choose SD card slot Because many cameras use SD cards, but we can only choose one, which needs to be weighed. In addition, more and more cameras are beginning to use wireless transmission, and it has proved to be very useful. So, we have taken a step further and let consumption Use a card reader or wireless transmission." Of course, many photographers may not agree with him. Although wireless transmissions are getting better and better, they are often cumbersome to use and slower than SD card transmission. In the professional field, speed and reliability are the most important, and Apple's choice is not satisfactory. When asked about the traditional headphone jack on the new MacBook Pro, but using new technology on the iPhone 7, this is a contradiction, Schiller said, professionals have many other audio devices without wireless capabilities, so the traditional interface is very necessary. "If it's just for headphones, it's really not necessary, wireless headphones are a good choice." In a later interview, Schiller went on to talk about the new MacBook Pro. He said he was surprised by the criticism of the outside world, but using the Thunderbolt interface is a bold decision, and Apple will help users "get through" these changes. As for how to help, it should be to buy accessories. HIFU Piezoelectric Ceramic Parts
High Intensity Focused Ultrasound (HIFU) technology is to focus ultrasound on a single point to produce high energy, function on the dermis and SMAS layer of skin, stimulate the proliferation and recombination of collagen, effectively achieve the effect of compact contour and smoothing lines.
Focused ultrasound does not heat the skin surface, nor does it need to pass through the skin as a medium for the transmission of laser energy, so it does not affect the tissue on the skin surface and the tissue through which the laser passes, of course, there will be no excessive heat residue on the skin surface. In this way, the epidermis will not be affected by heat, which can reduce the Eastern people's thermal reaction easily, and greatly reduce the chance of scald. Focused ultrasoundtherapy produces thermal coagulation points in the SMAS layer, and the thermal effect diffuses outward from the coagulation points, so the heat source is concentrated in the SMAS layer to be treated. It can produce more collagen denaturation.
