TAT, a design company from Sweden, once again demonstrated a user interface system called Velvet, which is mainly developed for the Meego tablet and provides users with a cool user interface experience.
First of all, let's introduce the TAT first. Although this design company is not very famous, the works are often amazing. The first Android mobile phone G1 is designed by TAT. They have also released many user interface systems for Android phones, such as TAT ​​Home, Fuse UI, Nexus, etc., all with unique 3D effects and touch experience. Has won the attention of Android users, but these interfaces so far have not really been applied to mobile phones.
The Velvet Velvet user interface system recently demonstrated is designed primarily for tablet products and is currently being developed based on the Meego platform. With the popularity of iPad, tablet devices will usher in explosive growth in 2010 and 2011, including Meego, Android, Windows 7, and other systems will be added to the competition. But what kind of user experience will these devices provide? How to design a user interface system?
After the trial, it was found that whether the mobile phone user interface is transplanted to the tablet or the complete desktop experience is reduced to the tablet, the tablet user can not provide a good user experience. Tablet PC user interface must be developed according to its own characteristics, including multimedia, web browsing, news reading and other common applications must be optimized for the tablet's screen size, touch operation and other hardware, let the tablet play its own Mobility and rich media features.
The Velvet Velvet User Interface System is an interesting conceptual system that supports 3D graphics and shadow effects for full dynamic interface effects. In the demonstration video, we can see that the entire interface uses a curtain-like drag operation, and the effect of dragging Google Maps as a curtain back and forth is very realistic. This interface provides a full range of plug-in, browser, application, video, music, pictures, search and other functional applications, are all centralized into one interface system for ease of use.
In the rectifier circuit; the use of diodes in series can increase the back pressure withstand value (usually the sum of the back pressure of all diodes, but it is best to use diodes of the same specification).
In the voltage stabilization circuit; the series connection of the diode is equal to the sum of the voltage stabilization value of the diode. The use of diodes in parallel is theoretically the sum of rated currents, but considering that it is impossible to be absolutely symmetrical, they can only be used below 80% of the total.
TVS transient suppressor diodes work in the same way as regulator diodes, but there are structural differences.The biggest difference is that the PN junction area composed of the general regulator diode is very small, it can withstand the reverse current is small.
